Hi,
I'm searching for a persistence framework to use, and actually I try to test
hibernate.
My problem at the moment is that i get a NullPointerException if I make a
lookup.
In the JNDI VIEW page i found the entry: +- SessionFactory (class:
org.hibernate.impl.SessionFactoryImpl)
But in the log file I found these entries, and i don't know what to do now.
server.log:
| ...
| [org.hibernate.impl.SessionFactoryObjectFactory] Not binding factory to
JNDI, no JNDI name configured
| ...
| [org.jboss.hibernate.jmx.Hibernate] SessionFactory successfully built and
bound into JNDI [SessionFactory]
| ...
|
hibernate-service.xml:
| <server>
| <mbean code="org.jboss.hibernate.jmx.Hibernate"
name="jboss.har:service=Hibernate">
| <attribute name="DatasourceName">java:/DefaultDS</attribute>
| <attribute
name="Dialect">org.hibernate.dialect.Oracle9Dialect</attribute>
| <property name="hibernate.default_schema">LAGERDBA</property>
| <property name="connection.pool_size">1</property>
| <property name="show_sql">true</property>
| <attribute name="SessionFactoryName">SessionFactory</attribute>
| <attribute
name="CacheProviderClass">org.hibernate.cache.HashtableCacheProvider</attribute>
| <attribute name="ShowSqlEnabled">true</attribute>
| </mbean>
| </server>
|
UserManager.java
| ...
| InitialContext ctx = new InitialContext();
| SessionFactory factory;
| factory = (SessionFactory) ctx.lookup("SessionFactory");
| Session hsession = factory.openSession();
| Transaction tx = hsession.beginTransaction();
| ...

Sample Hibernate File

|
| public void setCheckCount(Integer CheckCount) {
| this.CheckCount = CheckCount;

|
| public Set<AcUserToGroup> getSetOfAcUserToGroup() {
| return this.SetOfAcUserToGroup;
| }
|
| public void setSetOfAcUserToGroup(Set<AcUserToGroup> setOfAcUserToGroup) {
| this.SetOfAcUserToGroup = setOfAcUserToGroup;
| }
| }
