My deployed *.war file aren't running on a extern tomcat , lokal debugging (exploded) it's working correct. Rebuild doesn't help. Missing "test/info.hbm.xml" <hibernate-mapping> <class name="dbm.ThisEntity" table="testtable"> <id name="id"/> <property name="value"/> </class></hibernate-mapping> The first start are missing the table und therefor i exclude this from the compile. Why are the difference between exploded ( with the *.hbm.xml ) and WAR ( without the *.hbm.xml ) Release 8823 have the same bug.
