Wrong exception is thrown during entity's ejbCreate()

[sergeibatiuk]

Hello,

My env:

JBoss-3.0.2_Tomcat_4.0.4
JDK 1.4
Win2000


I have developed two ejbs: a sesson bean, DepartmentManager, and an entity bean, Department. DepartmentManager is responsible for creating new Departments:

public void createDepartment( DepartmentData dd ) throws DeptSysException, ValidateException {
try {
Context ctx = new InitialContext();
DepartmentHome deptHome = ( DepartmentHome )ctx.lookup( "java:comp/env/ejb/Department" );
deptHome.create( dd );
}
catch( ValidateException ex ) {
throw ex;
}
catch( Exception ex ) {
throw new DeptSysException( ex.toString(), ex );
}
}

the Department's ejbCreate() method first validates the supplied data and throws ValidateException if data is not valid, and then fills the fields with appropriate values.
DeparmentHome interface looks like:

public interface DepartmentHome extends EJBLocalHome {
public Department create( DepartmentData dd ) throws CreateException, ValidateException;
public Department findByPrimaryKey( Integer pk ) throws FinderException;
}


ejbCreate() method for the DepartmentBean:

public class DepartmentBean implements EntityBean {
..

public Integer ejbCreate(DepartmentData dd) throws CreateException, ValidateException {
try {
validate();
this.setData( dd );
return null;

}
catch( Exception ex ) {
throw new CreateException( ex.toString() );
}
}
..
}

the validate() method throws ValidateException if validation fails. However, the exception caught by DepartmentManager is not ValidateException, as expected, but javax.ejb.EJBException instead:

javax.ejb.EJBException: RuntimeException; CausedByException is:
javax.ejb.CreateException: bsv.depfunc.ejb.ValidateException: Validation failed

The ValidateException still appears on the screen, but it seems to be wrapped within EJBException. It looks like javax.ejb.EJBException to the DepartmentManager, not ValidateException.


What am I doing wrong? How do I force ejbCreate() throw ValidateException, so that DepartmentManager could catch it, without EJBException?

That is because you catch the ValidateException and convert it into a CreateException yourself...??

Thanks very much peterje!

Sometimes the more stupid the mistake, the harder it is to find! I think I never felt that stupid before...

I added the
}
catch( ValidateException ex ) {
throw ex;
}

and everything works perfectly, as it should!

Thanks,
