Hi!
I've used j2ee from Sun and everything worked. Now with jboss-2.4.4 this situation happend:
In EJB I've got this code:
private String dbName = "java:comp/env/jdbc/WDesignerDB";
private void makeConnection() throws NamingException, SQLException {
InitialContext ic = new InitialContext();
DataSource ds = (DataSource) ic.lookup(dbName);
conn = ds.getConnection();
}
Sometimes it works, but sometimes (after few calls of EJB bean) it throws exception on getConnection() method calling. I use MySQL (the new one) and mm.mysql JDBC driver (the new one too). The exception returns null getMessage(), so I do not know what is wrong.
Has anybody same problem?
Thanx.
