Cannot run on Tomcat 4.1.31 Â

2006-01-10 10:13

Hi there,Â

Â

I am having problems running JasperReports 1.1.1 on jakarta-tomcat 4.1.31. I believe the older digester jar file in tomcat/server/lib is conflicting with the one in my app /app/WEB-INF/lib/commons-digester-1.7.jar, but I cannot find a work around. The exception I see on startup is:Â

I have tried moving the jar files around to the different tomcat lib directories (shared, common) but to no avail. I am starting to believe that JasperReports simply cannot run on Tomcat 4.1.x. Does anyone know of a way around this problem? Your help would be much appreciated.Â

For those who are experiencing this issue, I found my problem and it may be yours:Â

Â

My app contained an older version gnujaxp.jar which was causing conflicts with the tomcat classloaders. Removing this jar file fixed the startup problems.
