I used mySQL Connector/J 3.0.6 as JDBC Driver in the environment of jboss 3.0.6 with jetty as servlet and jsp container. When the following jsp code executed, the error occured which said, "java.sql.SQLException: General error,  message from server: "Table 'logistics.po' doesn't exist" ". The jsp file is following:

try {
	stmt = conn.createStatement(ResultSet.TYPE_FORWARD_ONLY, ResultSet.CONCUR_UPDATABLE);
	rs=stmt.executeQuery("select po.id pid,po.company pc from tb_purchase_orders po inner join tb_order_status b on po.status=b.id where b.name='validated' and po.id='03020002'");
} catch(Exception e){

I tried to change the condition. The result is as following:
1. When I created a non-updatable Statement, the error disappeared.
2. When selecting fields from both joined tables, the error disappeared. 
   e.g. select po.id,b.name from ......
3. The error is not related to conn.setAutoCommit(false);

The error didn't occur under the version of MySQL Connector/J 2.0.14.
Infact, the error is not related to JBoss because I repeated the error in a simple java local program. 

How to repeat:
Write any program using jdbc which include codes above.
