Hi,
i'm new in RAP/Equinox and I have some questions around integration of
existing server side logic into RAP plugins.
First, what I have todo to deploy a RAP plugin on any standalone or
Embedded EE Webcontainer outside of eclipse (JBoss, Apache Tomcat)?
Can I generate an independet web application archive (*.war) of my rap
plugin by eclipse or ant? Wich files and dependencies are required on
server side application archive? E.g. howto configure and run the well
known 'org.eclipse.rap.demo' plugin on any outside EE server.
Second, How can I access request and session attributes within a RAP
application? I want to integrate existing logic (EJB3/JPA/JNDI) into my
RAP application. By web.xml I could define a Filter or RequestListener
wich injects a transactional persistence facade from JNDI context into the
request scope.
All servlets and jsp's could access the facade by a code fragment like
this: PersistenceFacade facade = (PersistenceFacade)
request.getAttribute("persistenceFacade");
Within my RAP plugin, wich class or factory is my entry point for
accessing attributes of request or session scope?
Thank you for any help or advice.

For a quick start, have a look at the RAP Help:
http://help.eclipse.org/ganymede/index.jsp?topic=/org.eclips e.rap.help/help/html/advanced/deployment.html
Deployment questions have been discussed over and over on this
newsgroup. You can search the archives for terms like deployment or tomcat.

RWT.getRequest() gives you a reference to the HttpServletRequest
instance that you can use to access the http attributes, session, etc.
