Administrative portlets (eg. Wiki Admin, Message Boards Admin) in Liferay - liferay

How can I create administrative portlet for my custom portlet, such as Wiki Admin for Wiki portlet in Liferay. Is it possible ?

Admin portlets are not something different then other portlets in the sense that they are just new portlets which re-use some of the functionality (service methods and some JSPs) of their counter-parts and add more functionalities for Administrator like add/edit/delete/assign-roles/assign-permissions/configurations etc.
So I think you just need to create a MyCustomAdmin portlet for your MyCustom portlet in the same WAR.
If you want the MyCustomAdmin portlet to appear in the control-panel then you can follow the steps here.
It just depends upon how you design your portlet so that you can re-use stuff to-fro between the two portlets.
I hope I have answered what you desired, if you have something else in mind then kindly update the question.
P.S.: I assume you are talking about custom plugin-portlets built using plugins-SDK

Liferay : How to see which portlets are composing a page?

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_">

Liferay: Page to portlet mapping

I have a requirement in liferay portal to allow user to add some specific portlets on a particular page. Same can be done in 2 ways:
This will require some custom code to be plugged in add panel code
create a custom portlet which will be present on left hand
side of page and allows portlet to be added and dragged on page.
On add of portlet it checks if the page can have this portlet and accordingly remove it
The question I have is which of these 2 approaches shall be used, and how?
Note: I was unable to find much about this on google as well
I believe Liferay permission system is strong enough to express what you need.
The portlet list shown in "Add more portlets" menu can be customized through a Regular Role. See How to customize which portlets to show in “Add more portlets” menu for detailed info.
To restrict the options for a single page (or several pages), modify its permissions, so that only the new Regular Role is be able to update it.
Based on your comment to Tomáš Piňos's answer, my suggestion would be to create a custom portlet that uses Liferay's API and enables you to do just this: On the page where it's available, use it to enable/disable the portlets you'd like to be there by use of Liferay's API. You'll find quite a lot of sample when you're looking for the old sevencogs example (that sadly does not compile any more, but in general the API has only changed marginally). The most up to date resources with further links to the ancient code are these 2 blog articles.
About your third option (as you ask in the comments): Yes, it's possible: You can override Liferay's Services as well as react to model changes. This means that you could add your own check on updates. However, I'd feel it inappropriate to offer the option to add any portlet only to prohibit it whenever a user indeed uses the offered option. That's why I didn't include this option in my initial answer.

Can we duplicate the titles of Liferay's OOTB portlets?

I am talking about the Add menu which appears for admins on the left hand side.
The requirement is that we want Liferay's portlet say, Blogs portlet to appear not only in the Collaboration category but also in a custom category say, Test Portlets with a different name like Test Blogs.
Also when the User adds the portlet Test Blogs then the title of the portlet on the page should also be Test Blogs.
Is this possible?
Why I want to do this?
Because we are using Application Adapters to customize some of Liferay's OOTB portlets and we want a different name for them in few sites.
It will be fine even if the portlet can be moved to a separate category with different name in few sites.
Thanks for any help in this direction.

Liferay Social Office - Is there a Related Content portlet?

I'm looking for the Related Content portlet in Liferay, and in particular for Social Office. I know about the Asset Publisher and Related Assets portlet. But I can seem to find the Related Content portlet? I'm using 6.1 CE of Liferay and I just installed the newest Social Office CE yesterday. Was this portlet removed/deprecated?
This page claims that there is this feature: http://www.liferay.com/products/liferay-social-office/features
And this page says the portlet should already be there. But I don't see it.
http://www.liferay.com/documentation/social-office/2.0/user-guide/-/ai/lp-2-0-soen01-social-office-features-0
Any help would be great. Thanks.
Related Assets will only display when there actually are related assets. Further, AFAIK it will not show when you show all blogposts (the documentation says it's on the Blogs page), but when you select one article.
Alternatively, if you have sufficient permissions, enable "Edit Controls" in the dockbar and the portlet will appear (greyed out and without content).
Another alternative, if it indeed is not there, you might be able to change the social office site template and add it to the template.

Using Liferay for an already developed project

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.
