jboss 4.0.2, hibernate3 and mysql NullPointer problem

jboss 4.0.2, hibernate3 and mysql NullPointer problem

I am trying to deploy a simple persistence class using hibernate3 on Jboss 4.0.2 with database being mysql.

Following is the my hibernate-service.xml

java:/mySQL
org.hibernate.dialect.MySQLDialect
java:/hibernate/SessionFactory

org.hibernate.cache.HashtableCacheProvider



My Customer.hbm.xml
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 2.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">
<hibernate-mapping package="com.anand.data">

<id name="no" type="int" unsaved-value="null" >
<column name="number" sql-type="integer" not-null="true"/>

<property name="name" not-null="true"/>

</hibernate-mapping>

My persistent class
public class Customer {

public int no;
public String name;

/**
* @return Returns the name.
*/
public String getName() {
return name;
}
/**
* @param name The name to set.
*/
public void setName(String name) {
this.name = name;
}
/**
* @return Returns the no.
*/
public int getNo() {
return no;
}
/**
* @param no The no to set.
*/
public void setNo(int no) {
this.no = no;
}
}

As soon as i deploy this my my jboss crashes. Any idea what could be wrong I am attaching the stacktrace below.

Hello, did you find the way to solve the NullPointerException error with Hibernate (during the execution of buildSessionFactory) ? I'm having the same problem.

Thanks in advance!

I have 2 comments:

- Your mapping files reference the 2.0 DTD. Outside JBoss this will cause the session factory to build very slowly because Hibernate attempts to locate a DTD externally which would ordinarily resolve to a location inside the jar. Perhaps it behaves differently inside JBoss?

- Did you copy commons-collections.jar to the hibernate deployer service directory like the getting started guide suggests?

I deployed my first HAR file last night using existing H3 mapping files (from outside JBoss) and it worked flawlessly. I'm using MySQL as well.

Hope this helps.

Thanks, that worked for me. I've now got:

jboss.har

* service=HARDeployer
* service=Hibernate

In the JMX Console window.
