[ORA-01400: cannot insert NULL into ... issue]

Hi,

i have problems running my application on a linux environment. The jasper reports are embedded into a web application. when clicking a report however i get a stacktrace.

It seems nothing can be insert into the jasper database, I use jboss510GA and oracleXE112

below part of the stacktrace.. I saw some topic on wrong dialect or so, but i have set it to Oracle10g dialect, should be ok....

Anyone a clue? Any more info needed?
