Testing web.xml filters from IDE launch [message #1752886]

Hi all,
is there a way to test/debub the behavior of a filter in web.xml from the IDE launch, that is, without having to deploy the RAP war into a Servlet container?
Thank you very much
Vincenzo

Hi,
In RAP Launch Configuration dialog you can specify to run RAP application from web.xml.
HTH,
Ivan

Thank you Ivan,
but I omitted to write that we are using the RAP Launcher.
We have RAP applications based on OSGi, with all the classic 3.x workbench, and we have always used the RAP Launcher up to now.

As far that I can see only the RWT Launcher provides a way to specify a web.xml.
Is it possible to use the RWT Launcher also in our scenario?
Thanks
Vincenzo

Thank you Ivan,
but maybe I could do with an intermediate solution where you can help us.
Let me explain.
In a classic JSP page I can do this:

getServletContext().getInitParameter("PARAM1")

and I can retrieve the PARAM1 value defined in web.xml like this

  <context-param>
    <param-name>PARAM1</param-name>
    <param-value>TEST</param-value>
  </context-param>

Now, in a RAP (with workbench) application, let's say I dare to do this:

RWT.getRequest().getServletContext().getInitParameter("PARAM1");

where does it look for in order to resolve the value?
Could I put some file with a given name in some internal RAP runtime folder in such a way it can resolve an find the value?

Thank you very much
Vincenzo

It looks at the embedded Jetty instance

You might be able to create a bundle that looks for a service called javax.servlet.http.HttpServlet
From that object you can get a ServletContext and call setInitParameter

I don't know if that would be the correct context, but it's worth a shot. It would keep your dev code completely separate in it's own bundle.

Thank you Chris,
it seems a good idea.
However now when if I try to set a parameter:

httpServlet.getServletContext().setInitParameter(...)

I get this error

java.lang.IllegalStateException
	at org.eclipse.jetty.servlet.ServletContextHandler$Context.setInitParameter(ServletContextHandler.java:1132)

I also tried to do this in a JEE thread

	RWT.requestThreadExec(new Runnable() {
			@Override
			public void run() {
				httpServlet.getServletContext().setInitParameter("PARAM1", "AAA");
			}
		});

but the result it's the same.

Ok, so turns out jetty won't let init params be set unless it is in the starting state.
