Hello, could someone help me? I will explain my problem : I'm using JBoss 2.0 final on Windows 2000 service pack 1 with Mysql 3.23.33 on a pentium III with 390 MB RAM. OS : Windows 2000 Service Pack 1 JBoss : JBoss 2.0 final JDK : java 2 sdk 1.3 J2EE : java 2 sdk enterprise edition 1.2.1 DBMS : MySQL 3.23.33 JDBC : mm.mysql-2.0.4-bin.jar I have created a database "RailTrackerDB" and I'd like to use it in my EJB's. When I start JBoss, I can see that it connects to mysql and to the right database. In that database, there is a table "CL". I have an EJB "Customer" that access to the table "CL". When I use this EJB on the sun J2EE reference implementation, it's all right; but when I try on JBoss, it tells me that it can't find the table "CL". What can I do to make him find this table ??? Is is a security problem ??? here is the error message : Erreur : java.sql.SQLException: Table not found: CL in statement [SELECT CLUID, CLID, SYNWID, CLNM, CLNMAB, CLALIA, CLBAI FROM CL WHERE CLID = '0211' AND SYNWID = 'ZR' ] java.sql.SQLException: Table not found: CL in statement [SELECT CLUID, CLID, SYNWID, CLNM, CLNMAB, CLALIA, CLBAI FROM CL WHERE CLID = '0211' AND SYNWID = 'ZR' ] at sun.rmi.transport.StreamRemoteCall.exceptionReceivedFromServer(StreamRemoteCall.java:245) at sun.rmi.transport.StreamRemoteCall.executeCall(StreamRemoteCall.java:220) at sun.rmi.server.UnicastRef.invoke(UnicastRef.java:122) at org.jboss.ejb.plugins.jrmp.server.JRMPContainerInvoker_Stub.invoke(Unknown Source) at org.jboss.ejb.plugins.jrmp.interfaces.StatelessSessionProxy.invoke(StatelessSessionProxy.java:175) at $Proxy1.getMinimumDetail(Unknown Source) at com.RailTracker.Client.CL.<init>(CL.java:27) at com.RailTracker.Client.CL.main(CL.java:41) thanks to help me.
