cewolf and tomcat 5.0.19

[ygzq]

Dear All,

my cewolf 0.9.8 works fine with tomcat 4.1.18.

However, it seams does not fit with tomcat 5.0.19 at all.

The exception generated was as follows:

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

Do you have the JCommon package in Tomcat's classpath?

Do you have the JCommon package in Tomcat's classpath?

/usr/local/tomcat/jakarta-tomcat-5.0.19/webapps/cewolf/WEB-INF/lib/jcommon-0.8.0.jar

the jar file is in the context directory.

it should be automatically loaded with tomcat.

JCommon-0.8.0 is a really old version, the current version 0.9.3.

as can be seen above, jcommon-0.9.3 is loaded in tomcat 5.0.19.
However, i had the same result as in the first post.

Thank you all for ur help and attention.

I had get around the problem by not running tomcat 5 as native standalone server.
