Can't get BMP Entity Bean Instance!!

Question

Hello
I have created a BMP Entity bean, and put on the findPrimaryKey method this code:
try {
context = new InitialContext();
DataSource ds = (DataSource) context.lookup(nombreConexion);
conn = ds.getConnection();
stmt = conn.createStatement();
rs = stmt.executeQuery("select count(upc) from musiccdejb where upc='"+ primaryKey +"'");
if (rs!=null && rs.next()) {    
countNumber = rs.getInt(1);
if (countNumber!=1) {
throw new Exception();
catch (SQLException e) {
System.out.println("Error ejbFindPrimaryKey"+e);
catch (Exception e1) {
System.out.println("Otro error ejbFindPrimaryKey"+e1);
Everything there seem to be ok, because the select return 1, so the primary key exist, but after that the container doesn't get the information for this entity bean, everything is null when I tried to acces the information.
Context ctx = new InitialContext();
MusicCDBMPHome musicCDHome = (MusicCDBMPHome)ctx.lookup("java:comp/env/ejb/MusicCDBMP");
boolean found = false;
try {
musicCDObj = musicCDHome.findByPrimaryKey("1");
found = true;
} catch (Exception e) {
found = false;
if (found) {
out.println(musicCDObj.getUpc());
out.println(musicCDObj.getTitle());
Please help me, I am working with JDeveloper 9i Release 2 and OC4J Standalone version 9.0.2.

Yes, I alredy did that, and this is te content of my ejbLoad:
String upc = (String)entityContext.getPrimaryKey();
ResultSet rs = null;
try {
context = new InitialContext();
DataSource ds = (DataSource) context.lookup(nombreConexion);
conn = ds.getConnection();
stmt = conn.createStatement();
rs = stmt.executeQuery("select count(upc) from musiccdejb where upc='"+ upc +"'");
if (rs!=null && rs.next()) {
if (rs.getInt(1)!=1) {
throw new Exception();
catch (SQLException e) {
System.out.println("Error ejbLoad"+e);
catch (Exception e1) {
System.out.println("Otro error ejbLoad"+e1);
Another suggestion??
