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

AcUser.java
package de.psb_gmbh.main.business.persistence.hibernate;

import java.util.Set;

public class AcUser implements java.io.Serializable {

 // Fields
 private String UserId;
 private AcGroup AcGroup;
 private String LoginName;
 private String Name;
 private String Password;
 private Integer CheckCount;
 private Set<AcUserToGroup> SetOfAcUserToGroup;

 // Constructors
 public AcUser() {
 }

 // Property accessors
 public String getUserId() {
 return this.UserId;
 }

 public void setUserId(String UserId) {
 this.UserId = UserId;
 }

 public AcGroup getAcGroup() {
 return this.AcGroup;
 }

 public void setAcGroup(AcGroup AcGroup) {
 this.AcGroup = AcGroup;
 }

 public String getLoginName() {
 return this.LoginName;
 }

 public void setLoginName(String LoginName) {
 this.LoginName = LoginName;
 }

 public String getName() {
 return this.Name;
 }

 public void setName(String Name) {
 this.Name = Name;
 }

 public String getPassword() {
 return this.Password;
 }

 public void setPassword(String Password) {
 this.Password = Password;
 }

 public Integer getCheckCount() {
 return this.CheckCount;
 }

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

 public Set<AcUserToGroup> getSetOfAcUserToGroup() {
 return this.SetOfAcUserToGroup;
 }

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

AcUser.hbm.xml
