I have been trying to integrate Apache OFBiz ERP into my existing web application which is written using Struts2 , Hibernate and Spring .
But OFBiz is written with servlets and jsp . Is this at all possible and if yes how .
OFBiz stands on its own with Tomcat embedded. It's certainly technically possible to use it with Struts2 and Spring but Hibernate is not needed. OFBiz uses its own Entity Engine, the same thas Atlas Jira is using underneath for more than 10 years. And yes, it's not for the faint or heart.

I cannot access remote EJB beans of our application server within a web application running on Glassfish 3 web-profile using jndi lookup.
Using full profile for our web-application or even testing with a console application we have no problem accessing jndi remote beans.
Exception:
Unable to acquire SerialContextProvider for SerialContext
We just hoped to make our web servers more lightweight.
The Web Profile version of Glassfish only contains EJB Lite, which doesn't support #Remote interfaces. You need the Full Profile which supports the full EJB 3 spec.
From the oracle docs:
The Web Profile of the GlassFishTM Server supports the EJB 3.1 Lite
specification, which allows enterprise beans within web applications,
among other features. The full GlassFish Server supports the entire
EJB 3.1 specification. For details, see JSR 318.
You can find a comparision of features included in Web Profile and Full Profile here (It was made for Glassfish 3.1.1 but it should be nearly the same for Glassfish 4 except some newer versions of some features). You can find a nice feature comparision between EJB 3.1 Lite and Full in this article.
Update:
As you wrote in the comment (and the initial question) you are not using any enterprise beans directly in your web application, but you are retrieving bean instances via JNDI. This doesn't work with the Web Profile of Glassfish because the functionality for remote lookups is not there, e.g. the CORBA and ORB modules are missing (there are some basic CORBA OMG APIs but only because they are needed by other modules).
As your goal was to make the server more lightweight, maybe this is another option for you: You can remove unused components and modules with the pkg command-line-tool or with the graphical utility updatetool. You could install the Full Profile of Glassfish and then remove obsolete components step by step to make the server more lightweight. More details about the tools can be found in the oracle docs.

I want to know that how to configure/run Activiti BPM in Grails?? I'm using fedora as my OS, Grails 2.1 . If their is any tutorial websites are is plz mention it also..
There is a plugin for Grails applications that provides much of Activiti within a Grails app. http://grails.org/plugin/activiti However, development has sadly stopped on it by the main developer. The last update was for Activiti 5.9 and Grails 2.1, though much of the plugin content seems to be built for older versions of Grails; for example, actions in the plugin's TaskController are all closures, not methods. Also, someone did issue a pull request to update it to 5.10.
I've been trying to puzzle through the source for that plugin myself. I keep vacillating between simply setting up a standalone Activiti server and utilizing the RESTful API from within a Grails Service class, importing a few of the Activiti classes into my Grails app, or trying to re-engineer the plugin to suit my needs (my site is stuck on Grails 2.0.1 for the time being).
I'm trying to include Grails applications into a Liferay portlet. I tried the Grails Liferay Portlets Plugin but it did not work for me at all.
Does anybody know any other possibilities? Which do you think is the best and why?
We had our Grails project integrated with Liferay at one point but it was a mess. Inevitably we pulled it out of Liferay and we were able to use Grails properly again. In our instance the question became, why are we using Liferay and do we really need it?
Now if you have a requirement for Liferay you might try simply using Spring Portlet support and use parts of Grails you like but not fully integration. Spring Portlets with Groovy were much easier and cleaner to do. If you simply want Grails goodies for services etc. you can try deploying a Grails WAR on the same tomcat and expose services to your portlets through REST, Hessian, Burlap or some other easy service serialization mechanism in Spring/Grails. In this case you have a Liferay UI app that calls your Grails services.
Once again, try some options, then decide if you truly need (or have) to use Liferay. With advances in Javascript UI packages, I'm not sure 'portlet' spec apps are as appealing as they once were and the word 'portal' is something that sounds good to management but inevitably means little to what needs to be implemented.
We are trying to look for plugins for Grails to make a CMS site. Any suggestions?

I've never used it but apparently it can be used as a stand-alone site or integrated into an existing grails app as a plugin.
There is also Alfresco plugin, though it's likely more focused on the document management side of Alfresco (it allows both Document Management and Web Content Management).
in a struts application, I have a filter that forces certain pages to be accessed only over https via redirection. I'm thinking in porting it to grails so my question is: In the this environment, is there a "grails" way to implement such filter or is it similar/the same as I did ? Thanks
The Spring Security core plugin has support for this. See section 17 - "Channel security"
