javax.transaction.RollbackException
I user a ejbCreate method to insert a record and fetch the generated id,the code is:
String sql="insert into questionTopic (name,parentId,description) values(?,?,?)";
PreparedStatement ps=conn.prepareStatement(sql);
ps.setString(1,this.name);
ps.setLong(2,this.parentId);
ps.setString(3,this.description);
ps.executeUpdate();
ps.close();
sql="select max(id) from questionTopic";
ps=conn.prepareStatement(sql);
ResultSet rs=ps.executeQuery();
if(rs.next())
this.id=rs.getLong(1);
rs.close();
ps.close();
when i execute the problem,it throws an Exception:
