Help stuck with JBoss 4.0.2 and MySQL 4.1.13
Hi All,
I have a HospitalBean which is called from a HospitalManagerBean which is a SessionBean.
The Manager code is as follows
public HospitalData addHospital(HospitalData hospitalData) throws EJBException,RemoteException{
HospitalData newHospitalData = new HospitalData();
try {
System.out.println("Debug in HospitalManager 1********");
InitialContext initialContext = new InitialContext();
System.out.println("Debug in HospitalManager 2********");
HospitalHome hospitalHome = (HospitalHome) initialContext.lookup(JNDINames.Hospital_Home);
System.out.println("Debug in HospitalManager 3********");
Hospital hospital = hospitalHome.create(hospitalData);
System.out.println("$$$$$$$Created Hospital$$$$$$$$$$$");
System.out.println("Hospital Primary Key" + hospital.getPrimaryKey().toString());
newHospitalData = hospital.getHospitalData();
return newHospitalData;
} catch (NamingException ne) {
throw new EJBException(ne.getMessage());
} catch (CreateException ce) {
throw new EJBException(ce.getMessage());
}
}
The Hospital Entity Bean is as follows
public abstract class HospitalEJB implements EntityBean {
private EntityContext context;
public Long hospitalid;
public String hospitalname;
public void ejbLoad() throws EJBException, RemoteException {
}
public void ejbActivate() throws EJBException, RemoteException {
}
public Long ejbCreate(HospitalData hospitalData) throws CreateException{
Long myid = new Long(UniqueIdGenerator.getId());
System.out.println("My id generated ====== "+myid);
this.hospitalid = myid;
System.out.println("My id generated ====== "+this.hospitalid);
System.out.println("Came in ejbCreate method of HospitalEJB");
this.hospitalname = hospitalData.getHospitalname();
return null;
}
public void ejbPostCreate(HospitalData hospitalData)throws CreateException,RemoteException{
System.out.println("$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$");
System.out.println("Came in EJB POSTCreate of HospitalEJB");
System.out.println("$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$");
}
public void ejbRemove()
throws RemoveException, RemoteException, EJBException {
}
public void setEntityContext(EntityContext context)
throws EJBException, RemoteException {
}
public void unsetEntityContext() throws EJBException, RemoteException {
}
public void ejbPassivate() throws EJBException, RemoteException {
}
public void ejbStore() throws EJBException, RemoteException {
}
/**
* @return
*/
public abstract Long getHospitalid();
/**
* @return
*/
public abstract String getHospitalname();
/**
* @param long1
*/
public abstract void setHospitalid(Long long1);
/**
* @param string
*/
public abstract void setHospitalname(String string);
public HospitalData getHospitalData(){
System.out.println("Came in get hospital data");
System.out.println("In Get method of HospitalEJB"+this.hospitalid);
System.out.println("In Get method of HospitalEJB"+this.hospitalname);
HospitalData hospitalData = new HospitalData();
hospitalData.setHospitalid(this.hospitalid);
hospitalData.setHospitalname(this.hospitalname);
System.out.println("In Get method of HospitalEJB"+hospitalData.getHospitalid());
System.out.println("In Get method of HospitalEJB"+hospitalData.getHospitalname());
return hospitalData;
}
public void setHospitalData(HospitalData hospitalData){
System.out.println("In Set method of HospitalEJB" + hospitalData.getHospitalname());
this.hospitalname = hospitalData.getHospitalname();
}
}
The bean is deployed properly.The tables are also created but when I run the application it gives the following error:
18:27:12,093 ERROR [LogInterceptor] TransactionRolledbackException in method: public abstract com.cygnet.medina.Hospital.Hospital com.cygnet.medina.Hospital.HospitalHome.create(com.cygnet.medina.Hospital.HospitalData) throws javax.ejb.CreateException,java.rmi.RemoteException, causedBy:
