I am planning to upgrade my company's intranet from liferay 6.0.6CE to 6.2CE. I have done some research on it but I am still confused on API part. Will my custom portlets need only recompilation or would they need a complete rewriting. I am also concerned about my Theme and Exts. I have a lot of customization in my exts and my theme. What would be the best way to move ahead?
Also I have a NFS file server and SOLR search server configured with my current deployment. Need suggestions on that too.
I've heard recently, that the Migration Tool (6.1 to 6.2) now also supports themes. It won't be pixel perfect though. Check what it can do for you.
There have been some APIs that changed. Contrary to the comments given to your question, I'd say "It depends": I don't know how much of Liferay's API you use or if you just add functionality on top. You'll have to find out for yourself. The migration tool might help you.
The things that have changed the most are: Themes (using Bootstrap, as of 6.2) and Document Library (now including ImageGallery, which was still available in 6.0). Migration of data should be smooth if you follow the documented upgrade path. Migration of your portlets and plugins will definitely require recompile (within the new plugins sdk or updated maven dependencies) and probably adaptation to some changed API calls. I've seen instances where this was simple, but I've also seen hard cases.
As there have been no more updates for 6.0 CE for quite a while, I'm recommending to upgrade though (other than #FeinesFabi in the comment). If you want to have a long-term stable platform that you don't need to maintain for yourself, EE would be the way to go (supported for ~7 years after release)
For ext changes, you'll have to be aware that there are no guarantees: Ext allows you to change the inner implementation of Liferay, and that's what nobody strives to keep stable, even in minor updates. If you're using ext, you'll always have to be aware of incompatible changes. Ext allows you to keep your changes out of the official sourcecode - so they're well isolated. It doesn't say anything about the underlying implementation to be stable. With great power (ext) comes great responsibility. Keep your ext as small as possible - whatever you can do outside of ext should be done outside and use the public API.
The basic upgrade path (for Liferay itself, not your plugins) is quite well documented in the User's Guide.

At our company we are using Liferay for portals. My biggest issue with developing for such a huge framework is that the restart takes a lot of time even on a decent PC. We're trying to use hot deploying were it's possible but this sometimes just doesn't work (dependencies require restart, PermGen space errors occurs sometimes and Liferay have to be killed, etc.)
What i'm thinking about is that with most of our portlet's we are not really using any Liferay specific services just the JSR 168 provided things which is a standard. So i'm wondering if there's any minimal portlet environments available for Jetty or Tomcat which we can use for quicker portlet development? Of course i know that once i encounter a Liferay specific service call this is not an option.
I was testing Apache Pluto earlier which is a full blown but still lightweight portlet container however it works differently the way the portlet wars are assembled (web.xml should be modified) and it breaks compatibility in our build environment with Liferay. So it's not an option but i'm looking for something similar.
I've never used life ray portal, but too much played with GateIn portal because IBM Portal is heay, mostly for quick development on JSR-286 i used gatein
Currently used for visioneo.org, very flexible for every kind of use, large community.
Here is short summary
Liferay Currently used for visioneo.org, very flexible for every kind of use, large community.
eXo Platform Awesome look and set of web applications embedded. Last generation portal, very impressive! Based on Gatein
JBoss EPP Based on gatein, and designed to work with JBoss middleware architecture
Gatein A great portlet container. Light weight, easy to use. But unlike Liferay and eXo, it does not ship with collaborative portlets (Forum, Wiki etc.)
uPortal Beautiful portal, though its CSS are very intrusive: some BIRT styles are broken by uPortal's css.
Pluto Not really a portal, Apache Pluto can be used as a development / test platform. Often considered as a reference for portlet specifications.
Jahia Great look however not based on standards: portlets are supported but not really highlighted, a specific module technology is used instead
You might want to try the JRebel integration for Liferay. There's an introduction Webinar available, I don't know if it fully applies to the current implementation (the webinar is a bit aged) but it will give you an idea of the product/project.
What is your approach for creating your own set of controls aka own Extensions Library? After a few years of Xpages development we have a huge set of controls that are general purpose for building UI, some web services etc. (Probably as most other developers.) When we start a new project now we have to copy the entire stuff from one database to new one which involves controls, jars, css, images, JAVA code ... and then you completely loose control to maintain some central version of this controls & codes, everything is scattered among several projects/databases and things get messy fast.
We have thought about creating our own extension library as described here
http://www-10.lotus.com/ldd/ddwiki.nsf/dx/Master_Table_of_Contents_for_XPages_Extensibility_APIs_Developer_Guide but there is not enough documentation for this topic and the entire development process is quite complicated (at least seems to me. I tried two times based on docs above going through eclipse plugin project -> feature project -> update site and still having some bugs around)
What is your experience and approach for creating and maintaining shared Xpages controls in your Domino environment? Is there some hidden feature we miss here that can help us?
Take a look at the XSP Starter Kit on OpenNTF and the XPages SDK to setup an eclipse environment for plugin development. You'll also want Eclipse IDE for RCP and RAP Developers. Install the starter kit and SDK into eclipse and you should be all set.
The starter kit is a sample plugin with all kinds of examples of phase listeners, components, etc. Once you want to deploy your plugin, create an update site from within eclipse and use the Update Site NSF available on your server install to place your update site. Once that's done, you can replicate that NSF to any other servers that may need the plugin.
For more information about the starter kit, take a look at this slide deck. There is also a github project for the starter kit. Documentation for the XPages SDK can be found here. And a video for setting up the SDK is available on youtube. Lastly, here's the documentation for setting up the update site NSF.
While we haven't gotten to that yet in XPages, our model for regular Notes design elements is to have a central template that contains the elements that are shared, with those specific design elements marked to inherit from that template. Sometimes, a database inherits design elements from two different central templates.
That way, those centrally controlled design elements remain the same in all databases.
I would recommend looking at some example's on github for how they have library/components setup. One of the more simpler examples that has just a single component built into a Library is Steve Pridemore's App Layout Extension...https://github.com/DominoDev, Another good one is Nathan Freeman's Starterkit: https://github.com/the-ntf/xspstarterkit. Hopefully these will help you get the file structure down on which files you need and how they work.
I am having trouble finding a NoSQL databases that officially support MonoTouch via a local DB on the device. If their are, could someone provide a list of them here.
According to http://nosql-database.org/ there's siaqodb. Note that others might support MonoTouch without being mentioned in that site.
Edit: a few more clicks shows that HSS Database (from the same list) also supports MonoTouch.
You might also want to look at which ones support iOS (e.g. with Objective C) and see if bindings are available (or write your own).
Take a look on Couchbase Lite xamarin's component
RavenDB supports an embedded mode, and can run on Mono using the "Munin" storage engine option.
Although, there has been talk in the user group lately about dropping Munin, and it's not usually recommended for production, so it may not be a viable option.
I've not heard of someone using it with MonoTouch specifically, but there are some running it on Mono. If you try it, please update comments here with your findings. Thanks.
A bit late, but still relevant:
I'm the author of MarcelloDB, and I just released version 0.3.0 on nuget.
MarcelloDB is a document DB, built specifically for mobile apps (light-weight, low memory usage) and supports Xamarin Android and iOS as well as the windows platform.
I still have some features I want to add before reaching v1, but the file format and existing api are allready quite stable.
I'm trying to determine which open source (or at least free) bug tracker works the best with Mylyn. My hope is to find something that "just works" with good Mylyn support. I want to avoid lots of configuration and maintenance to get it going or keep it working with Mylyn. Also, I'd like the interaction to support as many types of fields and data exchange as possible.
I've heard that Jira is the best one to use, but the project I'm working on is a private closed source venture, and the funds aren't there to pay for Jira. Same for FogBugz. I need a free solution for closed-source code. Possible options that I've heard of so far are Bugzilla, Mantis, Redmine, and Trac. Is there a strong preference between these? Are there other better solutions?
At this time, we're using SVN for source control, but may transition to GIT in the future. Not sure if that matters, but if it does, I wanted to mention it.
The bug tracker will be installed and run on a linux VPS server with Apache and MySQL installed. But it can be customized to run other software if necessary.
Bugzilla, Mantis or Trac all work just fine with Mylyn. I would say that the best one supported is and probably will be Bugzilla, since eclipse people use it for their own bug tracking, and Bugzilla connector is developed by core Mylyn developers.
I have installed Redmine at home. I have it up at running with Mylyn in Eclipse too. I have used Bugzilla previously, but I think Redmine's interface is much cleaner and I especially like the roadmap feature.
I work for a very small company (~5 employees, 2.5 coders). We have gotten away with no code or document management for several years, but it's starting to catch up with us as we grow a bit.
Any suggestions for a management system. Free is better, but cheap is acceptable. We just don't want to spend more time on installation/configuration than it is going to save us.
We use mostly VC++ 6, but we're branching into VC# 2008. Also, we need to keep track of mechanical drawings and circuit diagrams for several pieces of hardware, as well as user manuals for both hardware and software (but I don't really expect to find one tool that will do all of this, just hoping).
Subversion (SVN) is an excellent option for you. It's free, integrates nicely into Windows with TortoiseSVN, and is well-tolerated by users.
We are using it for source code, as well as for document management.
http://trac.edgewall.org/ - might be a bit hard to install but otherwise is very good if coupled with svn repository
Mantis is good for issue tracking. Subversion for source control. Both are free.
For documents, I do not know. Sounds like you would do fine with a network share.
You may want to look at Trac.
I work for a similar sized company, and when I got here I was in the same place as you. I implemented SVN/Subversion http://subversion.tigris.org/ quite easily. If you use the svn protocol and use svnserve (can be setup as a windows service that auto starts on your server) it should take you 1.5-3 hours to setup depending on how much you want to read http://svnbook.red-bean.com/, see collabnet http://www.collab.net/downloads/subversion/ for the Windows package download
Using Windows, you can use Tortoise SVN which integrates into the windows shell. There is also a new release of Ankh SVN (2.0) http://ankhsvn.open.collab.net/ that integrates into Visual Studio. Ankh is very nice (has pending changes window, kind of similar to Subclipse like functionality) but it is a new release and is somewhat buggy (we have experienced some memory probs and slowness). We currently use both Tortoise for initial checkouts or imports and Ankh for everything else and are pretty happy.
If you have any Mac users, there are a lot of options out there. We have a mac user here who uses Versions http://www.versionsapp.com/, though it sounds like they will charge for it once they get out of beta.
I would recommend SVN because it is widely used out there and I feel that is important with open source projects you are going to use daily for production purposes. Just to spell it out, everything (other than Versions) mentioned is free.
Perforce!
It's extremely fast compared to most other source control systems. It works great remotely. (SSH tunnels, in my case)
The VS plugins are quite decent... I haven't tried the Eclipse one that much yet.
If you can get by with two users with 5 workspaces each, then you can use it for free. (I do, currently)
If that won't work, then it does cost a bit... something like $800/user I believe. Sometime next year I'm probably paying that. (5 workspaces is tough when you work on several machines with VMs)
Still, I heard the slower-than-glacial ClearCase/ClearQuest system one client one mine is using was something like $10k per developer, so expensive where source control is concerned is a relative concept.
Don't skimp on the source control, man! Slow source control is a serious pain in the a$$.
Avoid SourceSafe-like systems that only version files... use systems that track tasks or change sets. It's very useful to see what all belongs together as a task. Tags are not an acceptable substitute.
Also, the journalling nature of Perforce makes backups and recovery a lot easier.
Use Git for source control, Basecamp/Pivotal Tracker/Unfuddled for coding workflow, and Sharepoint/Google Docs for document management.
If you get a MSDN developer license, you can run TFS workgroup edition. That has source control and document management rolled all up in one package that's pretty easy to use and manage. That, in addition to an internal wiki, is what my company does.
Use Subversion. It's free and is the preferred source control system for the vast majority of open source projects.
SVN uses shallow copies, so when you have large files in a repository and you branch, a full file copy isn't done... just a pointer to the original. As for text files (code) only diffs are stored.
Use TortoiseSVN for windows explorer integration.
TFS is a pig, and you'd need to open visual studio to interact with source explorer. Stupid for a CAD engineer to have to need a license to TFS for that.
For document management, just use Windows Sharepoint Services that comes with Windows Server 2003 (or 2008).
I also work for a small company and we mainly develop in .NET languages. We have decided to use Visual SourceSafe for source control, despite its questionable reputation, since it integrates nicely with Visual Studio. VSS works very well for us, and we have not experienced any serious problems with it. Also, we host a SharePoint server, which we use to store documents like coding standards, storyboards, and even our SCRUM log.
We use HostingPlayground. For $6 per month we get multiple Subversion repositories and an instance of Trac. Can't beat it. And since its a service its available immediately.
It seems the solution for your 'management' requirements will require at least a tool or set of tools in the following categories: (sorry about the links, not enough reputation to put proper ones in the reply)
Source Code Management
Trouble/Bug Ticketing
Document Management
Definitely take a look at stackoverflow.com/questions/15024/tools-to-help-a-small-shop-score-higher-on-the-joel-test Tools to help a small shop score higher on the joel test referenced by stackoverflow.com/questions/84303/code-document-management-for-a-very-small-company/84363#84363 Kristopher
Each have various free/open source solutions, and likewise there are commercial solutions.
Source Code Management (SCM)
A significant trend(?) of source code management is evolving from centralised code management with something like TFS(?), cvs or subversion.tigris.org svn), to decentralised 'distributed' source code management with tools such as www.selenic.com/mercurial/wiki/ or git-scm.com/. Some of the tools either integrate into continutation
The above mentioned source code management tools all have nice ms windows integration tools, and some even have closer Visual Studio integration (e.g. TFS, ankhsvn.open.collab.net/ ANKH svn mentioned by Mario).
A simplistic generalistion would recommend git/mercurial when your coding involves a good portion of time away/off disconnected from your centralised source code repository (such as doing a lot of coding from home when your repository is not accessible through the Internet.)
Wikipedia has a en.wikipedia.org/wiki/Source_code_management nice overview of the various issues related to source code management, and the benefits of various options.
If you haven't used scm before, just pick one or two of the tools that fits your groups requirements and test it. Of course, if you know someone near who has experience with a particular scm solution it may help with the team's learning curve to have that shared experience around.
My pick for your scenario: Subversion with ankhsvn.open.collab.net Ankh SVN for Visual Studio integration.
Trouble/Bug Ticketing
None of the tools available solve everything for everybody, each have their advantages and most require some compromise from a development teams existing modus operandi. Again, wikipedia is your friend with a en.wikipedia.org/wiki/Bug_tracker general summary and en.wikipedia.org/wiki/Comparison_of_issue_tracking_systems comparison of major tools.
Installation
The php based tools are the easiest (in my experience) to get up and running, and the perl tools more involved(?) Of course there's python one that's real easy to install, but then requires a better mind than mine to configure.
My pick for your scenario: trac.edgewall.org/ Trac
Trac is an enhanced wiki and issue tracking system for software development projects. Trac uses a minimalistic approach to web-based software project management. Our mission is to help developers write great software while staying out of the way. Trac should impose as little as possible on a team's established development process and policies.
It provides an interface to Subversion (or other version control systems), an integrated Wiki and convenient reporting facilities.
Trac allows wiki markup in issue descriptions and commit messages, creating links and seamless references between bugs, tasks, changesets, files and wiki pages. A timeline shows all current and past project events in order, making the acquisition of an overview of the project and tracking progress very easy. The roadmap shows the road ahead, listing the upcoming milestones.
Drawings/Document Management
If you use Subversion with Trac then much of your document management may be solved with these tools. Otherwise another stackoverflow discussion topic: stackoverflow.com/questions/587481/developer-documentation-sharepoint-document-management-vs-screwturn-wiki Developer documentation sharepoint document management vs. screwturn wiki, for Windows centric environment, is a good read.
