Subject Cocoon 2.0.4_vm14 + JBoss 3.2.1 + J2SE 1.4.2 troubles
Date Tue, 15 Jul 2003 15:55:39 GMT
Hi.

I've got some troubles trying to run cocoon 2.0.4 application in the 
JBoss-3.2.1_Tomcat-4.* environment with J2SE 1.4.2 installed. I deploy 
cocoon.war and then try to request http://localhost:8080/cocoon. As a 
reply I get the following exception:

===cut===
Cocoon 2 - Internal server error

type fatal

I've experianced this on Windows2000 and Linux RH8 with J2SE 1.4.2 and 
JBoss-3.2.1 boundled with Tomcat 4.* or Jetty.
On the plain Tomcat (without JBoss) everything is OK.
On the old J2SE 1.4.1 everything is OK, but I have to use only JDK1.4.2

Have any ideas? I almost don't know Apache Avalon framework and so I 
don't know what can I do with the problem.
