InvocationTargetException

[damir]

Cheers everyone.   I'm trying to run JPetstore on Tomcat 5.0 and Oracle 10g.   Everything installs fine, however whatever I choose I get the following exception:   «Error dispatching bean action via URL pattern ('viewCategory'). Cause: java.lang.reflect.InvocationTargetException»   Can you tell me what could be a cause for this? Thanks.
