Debug Seam using the "jboss-seam-debug.jar"

[toni]

Hi,

I would like to debug my seam application and have a look inside the contexts etc.

For that I have added the "jboss-seam-debug.jar" to the "/WEB-INF/lib/" directory of the WAR and inserted the following lines into the "web.xml" descriptor:

<context-param>
<param-name>org.jboss.seam.core.init.debug</param-name>
<param-value>true</param-value>
</context-param>

However, as soon as I try to access the webapplicaton the following exception gets thrown:

Servlet.service() for servlet Faces Servlet threw exception
java.lang.IllegalStateException: org.apache.myfaces.webapp.webxml.WebXml.init must be called before!

What do I have to change to make it working?

For anybody who has the same problem. Actually it says in the documentation that one should include the jar "along with the Facelets", which consist of the following jars: el-api.jar el-ri.jar jsf-facelets.jar

I think would be good to mention them by name in the docs.

Anyway, I have a new problem now: I can access the debug.seam page, but the content/type, which is returned is "text/plain" and I don't know how to change it to "html/plain". I added a mime type into the web.xml, but it does not work.

Well a workaround is creating a file "debugFixed.jsp", which contains two lines:

<%@page contentType="text/html"%>
<jsp:forward page="/debug.seam"/>

This was already fixed in the latest release of Seam.
