Hi,
I got the equinox bridge running in both Tomcat and WAS. I am wondering
how the equinox bridge accepts request. Is it possible get it work in
the follow senario:
Servlet A running in Tomcat,
Servlet B running in OSGi,
Plugin C running in OSGi,
Servlet A get a request. Can the servlet A forward the request to
servlet B through the equinox bridge?
Servlet A get a request. Can the servlet A forward the request to plugin
C through the equinox bridge?
Any suggestion or sample code would be greatly appreciated!
Susan

Hi Simon,
Thank you for your reply.
I decided to use the first use case. I did some prototype. However,
RequestDispatcher only works when servlet A and servlet B are in the
same WAR. In my case, servlet A is in WAR_A, servlet B is inside the
bridge WAR in OSGi. Do you have any suggestion on how to forward request
and response from one WAR to another WAR?

If you want to do inter-WAR RequestDispatching you first have to get the
other WARs context.
e.g. ServletContext.getContext("other")
....and then use that context to do your request dispatching
