      Hi all,

      I currently encounters a very curious problem on my Linux box, running RH 7.1, MySQL-Max 3.23.51, Sun JDK 1.4.0 and JBoss/Jetty 3.0.2.

      But when I try to get data using an Entity Bean CMP 2.0, I have the following error:

      ...

      It seems this is not not a JNDI problem. I guess it come from JDBC/persistence and I'm unable to fix this. But I have made several test. And the result is very strange. I can access to my Datasourse (my previuos Entity Bean uses the same) and my data with the following code into a Session Bean:

      DataSource ds = (DataSource)ctx.lookup("java:comp/env/jdbc/myDS");
      Connection con = ds.getConnection();
      PreparedStatement stmt = con.prepareStatement("SELECT * FROM user");
      ResultSet rs = stmt.executeQuery();
      if(rs.next())
      {
      str = rs.getString("email");
      }
      stmt.close();
      con.close();

      More curious: I have this issue only on my 2 Linux box. But it's working fine on Win XP workstation. Windows working better than Linux, I can believe that!!

      Quid.

      I hope someone can help me.

      Thanks,
      Alexis
