Jasper Digester Problem with JDK1.4 & Tomcat

2003-05-27 18:52

I'm able to have Jasper generate HTML reports fine as a Java app. But have a problem using it with Tomcat 4.1.24 and J2SE1.4.1 and J2EE 1.4b. My servlet runs fine but when Jasper tries to compile, it gets a class NoClassDefFoundError for org.apache.commons.digester.Digester (below). It may have something to do with conflicting XML parsers used by Jasper vs that used by Tomcat or JDK1.4. I'm so close to getting this web reporting work. I read the Tomcat 4.1.24 Classloading documentation but still can't get it to work. Can anyone help me? Thanks.

Hi,

 

Have you placed commons-digester.jar and the other

commons-xxx.jar files from the /lib directory of the

project into your WEB-INF/lib directory?

 

Your error comes from the fact that the Jakarta Digester

library is missing from the classpath of you web appplication.

 

Thank you,

Teodor
