No Such Entity Error

ateliersoft Sep 6, 2002 9:49 AM

Hello,

I am getting the following error when trying to deploy
an ejb jar with an entity bean connecting upto a mysql database. We are using the my-sql.2.0.6 driver. Does that give us a problem or is some configuration settings wrong. Thanks so much for answering.

thanks,

Hi,

Did you fix this issue?

I encounters the same problem. And this is very curious. I can access to my Datasourse 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();

But when I try to get the same data using an Entity Bean via the same Datasource, I have this error.

More curious: I have this issue only on my 2 Linux box(running RH 7.1 and JBoss/Jetty 3.0.2). But it's working fine on Win XP workstation.

Quid.
