Javax.transaction.RollbackException

Question

Please take few moments to look at this code. I can't see what I am doing wrong. Can you? it is about the RollbackException. the create method inserts a record in de database, but I am not sure if the container rolls it back, or may be the primary key class is not well implemented.
Your help is very appreciated. I am stack here since 3 days ;(
The create method in the Movie_LoanBean
public Movie_LoanKey ejbCreate (int Member,int Movie,int copy_number,java.sql.Date DayDate_Loaned)
throws CreateException {
if (Member == 0 || Movie == 0 || copy_number == 0 || DayDate_Loaned == null ) {
throw new CreateException(
"Rerquired fields are not filled.");
try {
insertMovie_Loan(Member , Movie , copy_number , DayDate_Loaned );
this.Member = Member;
this.Movie = Movie;
this.copy_number = copy_number;
this.DayDate_Loaned = DayDate_Loaned;
return new Movie_LoanKey(Member, Movie, copy_number, DayDate_Loaned);
} catch (Exception e) {
throw new CreateException (e.toString());
private void insertMovie_Loan(int Member,int Movie,int copy_number,java.sql.Date DayDate_Loaned)
throws SQLException {
makeConnection();
System.out.println("in insertMovie_Loan");
String insertStatement = "INSERT INTO Movie_Loan2 VALUES(?, ?, ?, ?)";
PreparedStatement prepStmt = con.prepareStatement(insertStatement);
prepStmt.setInt(1, Member);
prepStmt.setInt(2, Movie);
prepStmt.setInt(3, copy_number);
prepStmt.setDate(4, (java.sql.Date) DayDate_Loaned);
prepStmt.executeUpdate();
prepStmt.close();
System.out.println("leaving insertMovie_Loan");
releaseConnection();
The primary key class
public class Movie_LoanKey implements java.io.Serializable {
public int Member;
public int Movie;
public int copy_number;
public java.sql.Date DayDate_Loaned;
public Movie_LoanKey() {}
public Movie_LoanKey(int Member, int Movie, int copy_number, java.sql.Date DayDate_Loaned) {
this.Member = Member;
this.Movie = Movie;
this.copy_number = copy_number;
this.DayDate_Loaned = DayDate_Loaned;
public int getMember() {
return Member;
public int getMovie() {
return Movie;
public int getcopy_number() {
return copy_number;
public java.sql.Date getDayDate_Loaned() {
return DayDate_Loaned;
public boolean equals (Object obj) {
if ( obj == null || !( obj instanceof Movie_LoanKey ))
return false;
else if ( (((Movie_LoanKey) obj).Member == Member) && (((Movie_LoanKey) obj).Movie == Movie) && (((Movie_LoanKey) obj).copy_number == copy_number) && (((Movie_LoanKey) obj).DayDate_Loaned == DayDate_Loaned) )
return true;
else
return false;
public String toString() {
return String.valueOf(Member) + String.valueOf(Movie) + String.valueOf(copy_number) + DayDate_Loaned.toString() ;
public int hashCode() {
String tmp0 = String.valueOf(Member) ;
String tmp1 = String.valueOf(Movie) ;
String tmp2 = String.valueOf(copy_number) ;
String tmp3 = DayDate_Loaned.toString();
return tmp0.concat(tmp1).concat(tmp2).concat(tmp3).hashCode();

Answer 1

It means that your code somewhere throws a system exception.
Have you tried to debug you'r bean ? Run EJB server under an IDE with debugging capabilities (JBuilder, IDEA).
This would speed up your development.
Why do you use a BMP beans ? In this case CMP would work without any problems.
