[jboss-user] [Persistence] - HQL query doesn't have same result when deployed in JBoss

Hello everybody, I don't know if there is the good place for this post... Maven dependencies : - hibernate-3.2.4.sp1 - hibernate-entitymanager-3.2.1.ga - hibernate-annotation-3.2.1.ga - persistence-api-1.0 - mysql-connector-java-5.1.8 Application Server : JBoss 4.2.3 Database Server : MySQL 5.1 The hibernate library are those that can be found in the /lib folder of JBoss 4.2.3. I have a different behaviour when I test my application via JUnit and via my Web Application deployed under JBoss. I have a class MyClass with a property type. The type property is an enumeration define like that : @Enumerated(EnumType.STRING) I have the following query : SELECT m FROM MaClasse WHERE m.type = ? | | request.setParameter(Type.TEST); When I test the query with a JUnit test, the type parameters is correctly replaced by the "TEST" value in the sql query. If i deploy the WebApplication and do the same test the type parameters is not replaced by "TEST" value but by a strange value with hexa characters "2c14f2c45d47d58c8c8c8c8......" I've put the debug mode and I found that the Enumeration is not evaluated in the same way : - JUnit : EnumType - JBoss : SerializableType. My question is, why such behaviour ? Is there a specific link between JBoss and hibernate libraries ??? I tried to delete hibernate libraries from JBoss.. it didn't work. If someone has already encountered this kind of problem ?? Thanks in advance. ps : I can prepare a little test to reproduce the behaviour if you want. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4267892#...
