[TM4J-users] ClassNotFoundException: net.sf.hibernate.LazyInitializationException

[George T. <geo...@fr...>]

Hello Kal

Using tm4j-0.9.8, I try to call the following code

      TMAPITopicMapImpl tmapiTmImpl = getTmApiTmImpl ();
      QueryEvaluator qe = QueryEvaluatorFactory.newQueryEvaluator
(tmapiTmImpl.getWrapped());
      TologResultsSet rSet = qe.execute ("topic($T)?");

while the TopicMap is connected to MySQL using Hibernate

the "qe.execute()" throws the following...

ava.rmi.UnmarshalException: Error unmarshaling return; nested exception is:

The same code works OK when the TopicMap is connected to Ozone or XTM

I have included all these in my classpath

            libs/hibernate/c3p0.jar
            libs/hibernate/cglib2.jar
            libs/hibernate/commons-dbcp.jar
            libs/hibernate/commons-lang.jar
            libs/hibernate/commons-pool.jar
            libs/hibernate/connector.jar
            libs/hibernate/dom4j.jar
            libs/hibernate/ehcache.jar
            libs/hibernate/hibernate2.jar
            libs/hibernate/jaas.jar
            libs/hibernate/jcs.jar
            libs/hibernate/jdbc2_0-stdext.jar
            libs/hibernate/jta.jar
            libs/hibernate/mysql-connector-java-3.0.16-ga-bin.jar
            libs/hibernate/odmg.jar
            libs/hibernate/proxool.jar


and the Hibernate works OK except for the part of the Tolog.
Do you have any ideas on what should I do to overcome the
net.sf.hibernate.LazyInitializationException?

Thank you and have a nice Summer
George
