java.lang.IllegalStateException: removing bean lock and it h
Hi All,
I am using JBOSS 3 and CMP 2.0. DB is Hypersonic.
I have written a simple bean like this :
****************************************************
public abstract class CustomerBean implements EntityBean
{
protected EntityContext ctx;
public CustomerBean()
{
System.out.println("CustomerBean -- Constructor ");
}
// abstract get/set methods
public abstract String getCustomerId();
public abstract void setCustomerId(String customerId) ;
public abstract String getCustomerName();
public abstract void setCustomerName(String customerName);
// ejb specific methods
public void ejbActivate()
{
System.out.println("CustomerBean -- Activate ");
}
public void ejbPassivate()
{
System.out.println("CustomerBean -- Passivate ");
}
public void ejbRemove()
{
System.out.println("CustomerBean -- remove ");
}
public void ejbLoad()
{
System.out.println("CustomerBean -- ejbLoad ");
}
public void ejbStore()
{
System.out.println("CustomerBean -- ejbStore ");
}
public void setEntityContext(EntityContext ctx)
{
this.ctx = ctx;
System.out.println("CustomerBean -- EntityContext ");
}
public void unsetEntityContext()
{
this.ctx = null;
System.out.println("CustomerBean -- UnsetEntityContext ");
}
public void ejbPostCreate(String customerId, String customerName)
{
System.out.println("CustomerBean -- ejbPostCreate ");
}
// create a row - called when create() is called on Home Interface
public CustomerPK ejbCreate(String customerId, String customerName) throws CreateException
{
this.setCustomerId(customerId);
this.setCustomerName(customerName);
CustomerPK c = new CustomerPK(customerId);
System.out.println("calling PK = " + c.toString());
return c;
}
}

I get a exception like this:

Any Idea why it is occurring? Any tips would be welcome.
NOTE: IT'S WORKING ALL RIGHT WITH SIMPLE PRIMARY KEY FIELD.
Why is it like that?
Thanks,
Saroj
