Hello,
I am working on an editor based on GEF. I want to save and load the complete model from a database using hibernate.
I put the following libraries to the classpath of the plugin:
antlr-2.7.6.jar
commons-collections-2.1.1.jar
dom4j-1.6.1.jar
hibernate3.jar
javassist.jar
jta.jar
log4j-1.2.13.jar
mysql-connector-java-5.1.11-bin.jar
jb3-persistence.jar
asm-attrs.jar
asm.jar
c3p0-0.9.0.jar
cglib-2.1.3.jar
commons-logging-1.0.4.jar
dom4j-1.6.1.jar
hibernate-annotations.jar
hsqldb.jar
jboss-archive-browsing.jar
jta.jar
Now I tried to test some simple code but I always get a IllegalArgumentException:
Caused by: org.hibernate.hql.ast.QuerySyntaxException: DiagramElement is not mapped [delete from DiagramElement]
at org.hibernate.hql.ast.util.SessionFactoryHelper.requireClassPersister(SessionFactoryHelper.java:158)

... 44 more
I do not know how to solve the problem. It seems that something of the plugin-path is wrong because if I add a Class with a main and run its main with the same code as Java-Application everything works fine..
I would really appreciate any help!
Thanks in advance & best regards
Alex
