accessing the HttpServlet or ServletContext [message #81852] Mon, 07 April 2008 09:08 Go to next message

Hello all,

I need to access the HttpServlet or ServletContext of the running
BridgeServlet before the first request. That's why I can't use
org.eclipse.rwt.RWT.
Is there an easy way to get one of them in my own bundle?

regards
Peter

Hi Peter,
can you explain what you want to do? I'm not sure whether I understand
your question but you can use
RWT.getRequest().getSession().getServletContext() to get the servlet
context. However this only works if you are within a request.

Regards,
Stefan.

Hi Peter,

unfortunately I don't have an answer to your question right away. But as
the problem you're describing is nothing special to RAP, but belongs to
every servlet mapped to osgi's http-service, you may have a look at the
equinox mailinglist/newsgroup whether this question has already been
raised there.


Ciao
Frank

Hello Stefan,

we use rap as frontend of a non osgied system. Beside rap with the
servletbridge, we start a spring context inside the same webapp. Now we
would like to provide this spring-context, which is contained in the
ServletContext, to our rap-ui-bundles inside the osgi-runtime. This has to
be done bevore the first request, maybe in a bundle activator.

regards,
Peter

Hi,

the bundle Activator seems to be a reasonable choice. If your spring
context is loaded using the webapp classloader you can configure the
web.xml to make the necessary classes available within the RAP app. See
'extendedFrameworkExports' in the org.eclipse.rap.demo.feature's web.xml
for more information. Note that you must use package import instead of
bundle-dependencies to provide the according types at development time.


Ciao

This way we can use the classes deployed outside the osgi. That's it how
we use it now with the sping context as static member of one imported
class.

This works fine, but how about non static access to the spring-context. I
thougt it would be a better way to get the instance contained in the
ServletContext direct?

regards,
Peter

Hi Peter,

I'm not sure if I really understand, but you can access the OSGi
provided HttpContext using:

ServiceReference reference ...
String name = HttpContextExtensionService.class.getName();
ServiceReference serviceRef = context.getServiceReference( name );
HttpContextExtensionService service
= ( HttpContextExtensionService )context.getService( serviceRef );
HttpContext rapContext
= service.getHttpContext( reference, "org.eclipse.rap.httpcontext" );

Unfortunately I don't know a way to get to the ServletContext object
this maps to. As this belongs to the equinox stuff, maybe there is more
information available in the equinox newsgroup/mailinglist.
