I can't tell you why you get this error, but i can tell you how we are debugging cocoon enabled web applications in a similar environment as yours:
We are running eclipse, cocoon-2.0.4, tomcat-4.1.18 on solaris and linux. We run eclipse on a PC-frontend and we always start the tomcat server with the startup scripts. When debuging whichever webapp (including cocoon) we set the JAVA_OPTS as follows:
-server -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8000
Then we (re)start the tomcat server as usual with "startup.sh" or "startup.bat". Please note, that we set the JAVA_OPTS, not the CATALINA_OPTS for this, although the docs at the tomcat site state something else (that does not work for us)
On eclipse we set up a remote debugging session on port 8000. This works perfectly! It should also work, when the tomcat server is running locally.

Hi,
I try to use the combination of Eclipse, Tomcat and the Sysdeo Plugin to debug the cocoon source in Eclipse. This doesn´t work (error message when trying to access any Cocoon resource at the end). When I start Tomcat via the startup.bat everything works fine.
My environment:
Windows 2000
Eclipse 2.1 (Beta)
JDK 1.4.1_02
Tomcat 4.0.6
Sysdeo plugin for Eclipse 2.1 (Beta)
Cocoon 2.1-dev
I´ve also tried JDK 1.4.0, Tomcat 4.1.18 and Cocoon 2.0.4 in various combinations with no success.
All the Xerces and Xalan libs are replaced with the ones from Cocoon in the directories [JAVA_HOME]/jre/lib/endorsed, [CATALINA_HOME]/common/endorsed and in [ECLIPSE_HOME]/plugins/org.apache.xerces_4.0.7 (probably not necessary because not in the classpath of my webapp)
Does anyone have an idea what´s going wrong here?
Thanks in advance Helmut
