Hi all,

I am getting the following exceptions when trying to creat an Entity bean. Here is the 
stack trace :
  
10:57:39,854 WARN  [JBossManagedConnectionPool] Exception destroying ManagedConnection

I am currently having a problem with the Sybase datasource that i am using. On 
deployment of the .ear file it connects to the DB creates the tables with no 
exceptions. I can also get a handle to it through jndi and execute an sql query again 
with no problems.

The error is caused by the "java.sql.SQLException: JZ0C0: Connection is already 
closed" exception.

Does anyone know what might be causing this.

Here is the text of my sybase-ds.xml maybe i am missing something.


  <local-tx-datasource>
    <jndi-name>jdbc/HylafaxDB</jndi-name>
    
<connection-url>jdbc:sybase:Tds:DBMS52:5000/hylafax?JCONNECT_VERSION=6</connection-url>
    <driver-class>com.sybase.jdbc2.jdbc.SybDriver</driver-class>
    <user-name>user<user-name>
    pas
