As I said before ('bout 3 days) we're using own DataBase for storing CMP's, everythings fine, we can lookup, store, findByPrimaryKey, findAll etc. But during startup of jBoss there's this weird Exception. We changed to class-Name as you said but nevertheless this Exception...What went wrong or what file do you need to locate the mistake? We didn't make any changes to your jBoss with embedded Tomcat but added our DataBase connection in StandardJaws.xml, jBoss.jcml and to .conf I think it's too much to give you everything 'cause it works as we want even with occuring of this Exception. But it doesn't look like working ok... Here again the printout: ...
