If workbench can achieve everything, then why do we have an eclipse plugin for development?
If workbench has the entire functionality right from defining rules to exposing restful apis, then eclipse would be redundant right?
Or am I missing something?
I am new to jbpm/drools and before proceeding, wanted to understand why both of them exist instead of just 1.
JBPM/Drools can be used in standalone mode or embedded mode. In standalone mode, workbench seems to be the best way to create and manage rules and processes. In embedded mode, jbpm/drools is embedded into an existing project. In that case, it is good to have an eclipse plugin for jbpm/drools so that entire project can be developed in a single platform.
In my experience, even if you use workbench, you still have to develop some java classes(using an IDE) outside of workbench.
Moreover, it is up to developer to decide what suits better.

I need to create a web based project where I will use java codes to do the back-end processing and database connections. So I need to write my code in JSP. I already installed tomcat.
But in Aptana i do not get the option "New Dynamic Web Project". Which i have created JSP projects previously. Any one knows how to add it or what toold i need to install?.
I'm not a fan of Aptana; in my experience it's a bloated tool that tries to do too much and does nothing particularly well. I would just get the Eclipse IDE for Java EE Developers package from http://www.eclipse/downloads and use that.
My base need is to use the Jersey framework to develop very basic REST webservices.
I've read several tutorials regarding Jersey (JAX-RS framework) and writing webervices but so for I've not found an easy way to setup a development environment based on Eclipse Helios and Glassfish (Open Source Edition). When creating a Webservice in Eclipse, it seems to use JAX-WS, or when creating a Dynamic Web App, Eclipse reports a credentials error (I use admin/admin) or a wrong user name / password.
The tutorials I've found either use myEclipse, or Tomcat, or Maven. The later works pretty well but I wish I could avoid using the command line because creating the web.xml and other files like that one is really scary, and I'm not sure these files are supposed to be human-written. So I suppose (maybe I'm wrong) using a IDE will make things easier.
What do guys use ? How do you generate these files ? Do you use Eclipse only for writting code or also use the deploy facilities?
Any pointers are appreciated !
Thank you

You DO need to modify web.xml whenever it's needed. Especially with JAX-RS, you will have to define your servlet in web.xml.
I recommand you to use Maven. There are plenty of exemple in the web to do so. Good luck, JAX-RS is really great ! Maven is also nice.
I also use eclipse for creating and consuming web service based applications. In addition to WTP, I also use Axis plugins to make things easier (through wizards, highlighting as well as for schema verification).
The bottomline is to find the plugins that suit you the best
I'm trying to learn how to develop a j2ee web application but is currently figuring out what's the advantage of using seam-gen vs eclipse seam web project or vice versa.
Why would I use one over the other?
Thanks,
czetsuya
Command line seam-gen stuffs the whole application into a single project and included some files that we didn't need (6 versions of the messages file, for example, each in a differnet language).
The eclipse jboss tools seam-gen produces a bit more modular, streamlined app. It generates 3 separate projects (4 if you want a test project). It took some time to get used to it, but once I got it down, I prefer it. Additionally, when you create he project in eclipse you can leverage more easily the benefits of using those integrated tools.
You can do this with a seam-gen commandline-generated project as well by creating an eclipse project using your seam-gen project as source , but it takes some fiddling around in eclipse to get the settings just right.
My recommendation is to go with eclipse/jboss tools. If you come from a command-line centric background (as I did), the learnign curve may be a bit steeper, but in the end it will be worth it. Use the jboss tools forum for questions you have about this project.
Good luck. Once you get going with eclipse/jboss you'll find it's a great environment to work in.
We have three Eclipse RCP applications running in parallel. Now I need to implement another RCP that displays/operates part of the running applications. In Windows the solution would be to provide the functionality as OLE-Control.
How can I achieve the same thing in Eclipse?
There is some limited OLE interation (OLE Documents and ActiveX controls) in the OLE SWT package available in the win32 version of SWT. You would need to make sure that you ran different versions of this RCP app on win32 vs another platform or you encapsulated any per-platform code in a fragment.
See http://www.eclipse.org/articles/article.php?file=Article-ActivexSupportInSwt/index.html for an introduction to SWT OLE integration.
There isn't an OLE/inter process communication within Eclipse. You can stick to plain Java way of doing things (such as a TCP-IP connection between processes)
I have a running dynamic web project in Eclipse (Java EE + Maven + Spring). I am at the point where I need to integrate a persistence layer and want to use Hibernate with a MySql database.
I am wondering what plugins would be useful for me at this point? For Hibernate should I install hibernate tools or is it not necessary? Are then any plugins that are most widely use for connecting / exploring database connections that would be appropriate for the type of project I am working on? Thanks.
Hibernate Tools is definitely a nice plugin (that provides wizards, a nice console useful to setup the HQL queries, a mapping editor, etc). I'm actually tempted to say: why not using it? I use it in conjunction with the database support provided by the Eclipse Data Tools Platform (that is included in the Eclipse IDE for Java EE Developers or available via the update manager). In your case, I would maybe just consider using SpringSource Tools Suite as base instead of a vanilla Eclipse.
Update: As reminded by BalusC in a comment, the Hibernate Tools also include a database reverse engineering tool which is maybe the most powerful feature. I should have mentioned it, this is now fixed.
You can look at http://fast-code.sourceforge.net/ as well. You can create FooService and FooServiceImpl and the configurations just by typing foo. It has nice way to create unit tests as well.
