2:12 a.m.
Environment:
1. Standalone Tomcat 6 (as serlvet container)
2. Standalone JBoss 4.2.2 (as ejb container)
I invoke methods (from webapp that deployed on Tomcat) on ejb3x beans that deployed on
JBoss. As result of work of some methods I should get object with lazy loaded
relationships, but in reality I have:

I have copied to tomcat's 'lib' folder almost all jboss's client
libraries that related to ejb3 and hibernate but it doesn't help.
List of libs:
antlr.jar
commons-logging.jar
concurrent.jar
ejb3-persistence.jar
hibernate-annotations.jar
hibernate3.jar
javassist.jar
jboss-aop-jdk50-client.jar
jboss-aspect-jdk50-client.jar
jboss-client.jar
jboss-common-client.jar
jboss-ejb3-client.jar
jboss-j2ee.jar
jboss-remoting.jar
jboss-serialization.jar
jboss-transaction-client.jar
jbosscx-client.jar
jbosssx-client.jar
jnp-client.jar
Excerpt from my orm.xml:
| <entity class="mypackage.MyClassName"
name="MyClassName">
| <table name="MYTABLE"/>
| <attributes>
| <id name="id"><column
name="ID"/></id>
| <basic name="name"><column
