I would like to know if built in functionality exists or how to implement functionality to search the static text of JSPs not web content of all deployed portlets in liferay from a centralised portlet (or theme). Unfortunately, there does not seem to be help regarding this issue.
Thanks.
This could be helpful. You must get rid of long and ugly URLs and use Liferay API's mentioned in that Wiki.

I'm new to liferay.
I imported a big lar into my liferay instance but, for the moment, have none of the required portlets : there are a lot of portlets in the project I'm joining.
Currently, I have the site structure, but the pages display the message that the portlet is not here (logical).
For comprehension purposes, I wanted to build my portlets one after the other, on the need, to see them appear by the grace of liferay ;-)
But for that I wanted to know which portlet is missing.
This thread : How can i find - which portlets are deployed on which pages in Liferay 6.1? explain how to achieve this through the DB.
Is there really no built-in solution to do it through the liferay interface? Have we really to hack in the DB to get the info or install plugin?
Thanks!
In your browser console, Liferay.Portlet.list contains all portlets in the page.
This value is generated by themeDisplay.getLayoutTypePortlet().getAllPortlets() on the server.
As an alternative you can also look at the HTML code of the page and look for elements with the class portlet-boundary. For example this belongs to an instance of the Journal Content Portlet (Portlet name 56):
<div class="portlet-boundary portlet-boundary_56_ portlet-static portlet-static-end portlet-borderless portlet-journal-content full-screen" id="p_p_id_56_INSTANCE_WdRdMGe86kDa_">
I have a portal in Liferay 6.2, and need to design the velocity template of a web content that must have a menu listing the pages (linked names) of the site where is present.
My questions are:
Is this possible?
What would be the correct way to do this?
Would it be better to make a portlet instead of a web content for this purpose?
Thanks for the help.
It feels a bit like you are trying to solve many problems in a single template - consider to compose the UI from many different elements (e.g. custom portlets) rather than building the one structure/template that fits all requirements.
That being said, as there's also the chance that your template doesn't do more than just displaying the current navigation: You have two options: The out-of-the-box Navigation portlet is quite configurable, you might be able to utilize that one instead of implementing anything yourself (check the configuration options).
And lastly, if you want to implement for yourself: Get hold of the themeDisplay object. With getLayout() you'll get the current page, while getLayouts() you'll get all pages of the current site and can enumerate them. However, there's one problem: You typically don't have access to the themeDisplay object from a CMS template. But there are several ways to still get to the data (search the Liferay forums for cms template themedisplay). Also, an Application Display Template will be a lot more powerful - and you can also check how the layouts collection is built - just search for usage of ThemeDisplay.setLayouts in Liferay's source code. But with ADT we're diverting from your original question.
Liferay offers a sitemap portlet out-of-the-box which lists pages of a site. You can configure it and define your own application display template (ADT).
I know this is a duplicate post but I needed help here. I had posted about my query before on how should I approach to migrate a website which is currently in OpenCms into Liferay.
I will share whatever I have found on internet and a reply that I got in one of the forums here on stackoverflow.
I was suggested to use ftl templates. but won't it be like executing the code everytime the user makes changes to a web page?
The website has static as well as dynamic pages. I need a way to recreate them in liferay so that in future if the users wish to change the data content of website they can do so easily. IN case of dynamic pages they will upate their database. IN case of static pages they would want to change data (if required) from liferay framework.
How should I create templates and add pages that use a particular template and also add content to the pages?
SHould I write a code or can I do directly from the liferay UI ? Is there a quick way to do this?
Regards
First of all, let me tell you what I am or my company is intended to do. We have already developed a project using Java, JSP and Servlet. We want it to integrate with Liferay so that we can change logo, css, images, themes or any other UI related component at run time using Liferay admin panel. But backend should be what we have developed.
In short, the UI of our project is controlled by Liferay, but control of data displayed on UI or submitted from UI should be from our developed backend code.
Now I have a few questions regarding above said approach of fulfilling the requirement:
What we are trying to do is possible?
Is this approach recommendable for what we intended to do?
Or do we need to develop our project from scratch to fit into Liferay? Like developing portlets and deploying in Liferay or other approach that has been given in Liferay documentation.
What about database integration? We have around 15 columns/fields in user table in database of our project which is completely different from that of Liferay's user table.
Liferay is a very new for us. We have checked the documentation section of Liferay but still few things like above said requirements and its implementation is not clear. Also, we would like to know in what scenarios/requirements Liferay is useful.
Ok let me try to answer your question point-wise and I would answer your last question first, which should automatically clear other questions:
Q. Also, we would like to know in what scenarios/requirements Liferay is useful.
This can have a very wide answer, but I have made it shorter for you:
If your site is content heavy and not data heavy then go for Portal
If you plan to use only a single web-application in a portal then I would suggest standalone custom developed web-application is much better.
I agree liferay portal will give you lot of things out-of-box like Single Sign-on, authorization, authentication, friendly-url and page creation and also lot of applications like Blogs, Wikis, Document library, some social networking apps etc. But think about it, do you really need all this? if not, then this is overkill
Here are some really nice links to better understand a portal's usage:
When to use a portal
Why to use portal technology
liferay tag wiki: It has nice description as to what is liferay and it also contains relevant links to Admin guide which will tell you what all functionalities liferay has and how you can manage it.
So still if you find your other questions unanswered, read-on ...
Q1. What we are trying to do is possible?
Nope. Portlet technology is different from Servlet technology. Liferay (or anyother portal) does not provide a way (atleast a simple one) to integrate servlets that would render pages inside a portal. For eg: Since with servlet you define URL mappings for a particular servlets before-hand in a web.xml but in a portal the URLs are generated by the Portlet Container. So portals work with portlets and not Servlets.
Q2. Is this approach recommendable for what we intended to do?
Nope. As I already explained in Q1.
Q3. Or do we need to develop our project from scratch to fit into Liferay? Like developing portlets and deploying in Liferay or other approach that has been given in Liferay documentation.
If you want to go the liferay way then Yes.
If you want to build applications that talk to your custom tables then portlets are the way to go.
Q4. What about database integration? We have around 15 columns/fields in user table in database of our project which is completely different from that of Liferay's user table.
If you go with Liferay. In this scenario you can create a combination of liferay-hook & portlet (may be using service-builder) to customize liferay's User creation mechanism and there by store data in both Liferay's User table and your custom tables.
Liferay's permission system is really fine-grained so you can also benefit from this system and put permission even on the data level.
In conclusion I would say:
Everything boils down to what your requirements are and what resources you have. And sometimes what future requirements you can have.
Note: All the terms used in this answer which are specific to liferay (like service-builder, hook etc) are explained in the liferay tag wiki.
Hope this helps. If you would like to know anything specific I would gladly update my answer.
I've developed with WPS and WCM for several years and now I am also learning Liferay. I can't help but compare the features and I understand that in Liferay some things are done differently.
I would like to know the best practices to manage the following simple example:
A simple page with a carrousel with several images and links
Google analytics inserted in the page (Reusable in most pages)
The following is how I'd solve it in IBM WPS:
A HTML component with the Google Analytics code that is called in every page (I can't find how to do this in Liferay)
A content definition of an image and a link.
Create several contents for each image and link.
Create a menu that shows the list of content in the form of a carrousel (I can't find how to do this either in Liferay)
I am aware that Liferay has a list portlet and content that has repeatable items. I know I could use these, however its much more usable if I can have on content for each image/link and one reusable HTML snippet of code.
How should I solve this in liferay in the most efficient way?
Thanks!
You have to use Liferay Web Content portlet for creating the carousel. This is available in Control Panel. For your particular requirememnt you have to create a dynamic web content, which involves using of Velocity language and javascript to iterate over a set of images. Infact if you see Liferay's website, the home page has this kind of stuff.
For Google Analytics there are two ways. Liferay is not just meant for creating one site, it caters creation of multiple sites. Each site has a group of pages. You can create site from Control panel again. In the site settings you have this option to add google analytics id. So with each site can have different google analytics id.
If you want to do it at a global level, we add the google analytics script snippet in the Theme of liferay.
To get a better understanding of all the jargons used in Liferay, you have to atleast go through Liferay's documentation. And while going through it you have unlearn what you have previously learned. Liferay has hell lot of features than Websphere portal.
