Hi, I posted this problem few days ago. Someone also has the same problem. But it seems no solution util now. This should be a easy for you gurus but frustrate me a lot. My jvm is 1.4.1. I repeated my problem as follows
I checked out cocoon2 from cvs and build a webapp > with the folloing command > > .\build.bat -Dinclude.webapp.libs=yes > -Dexclude.webapp.javadocs=yes > webapp > > I installed the web ap on tomcat 4.1.18 and access > the firt page with url http://localhost:8080/cocoon/, > then the error responed as shown in the following, > what is wrong? type fatal message Failed to execute pipeline.
