Hi, I have a problem with datasource, if I don't close the connection , jboss seid me:
org.jboss.resource.connectionmanager.CachedConnectionManager] Successfully closed a connection for you. Please close them yourself: org.jboss.resource.adapter.jdbc.WrappedConnection@2fcdf5
java.lang.Exception: Stack Trace

But, when I try to close the connection, with next code:
public Collection ejbFindAvailable(String sUser,String sPass) throws FinderException {
int iID=0;
ArrayList aUsuarios = new ArrayList();

String sGetUsuario="{call pUsuario_ValidateUser (?,?)}";
try {
ResultSet rsUsuario;
CallableStatement prstmt = con.prepareCall(sGetUsuario,
ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READ_ONLY);
prstmt.setString(1,sUser);
prstmt.setString(2,sPass);
rsUsuario=prstmt.executeQuery();
while (rsUsuario.next()) {//You are supposed to return a collection with the keys
iID =rsUsuario.getInt(1);//And findbyPrimarykey will return the instance
aUsuarios.add(String.valueOf(iID));
}
this.closeConnections(rsUsuario,prstmt,con);
} catch (Exception ex) {
throw new EJBException("ejbFindByAvailable: " + ex.getMessage());
}
return aUsuarios;
}
public void setEntityContext(javax.ejb.EntityContext entityContext) throws javax.ejb.EJBException, java.rmi.RemoteException {
this.context = entityContext;
try {
makeConnection();
} catch (Exception ex) {
throw new EJBException("No se puede conectar a la BD del Tren. " +
ex.getMessage());
}
}
private void makeConnection() throws NamingException, SQLException {
try{
InitialContext ic = new InitialContext();
DataSource ds = (DataSource) ic.lookup(dbName);
con = ds.getConnection();
System.out.println("Se conecto a la bd");
}catch (Exception ex) {
System.out.println("getConnection failed. See error log for stack trace.");
}
}
private void closeConnections(ResultSet res, CallableStatement cs,Connection c) {
try {
if (res != null){
res.close();
res=null;}
if (cs != null){
cs.close();
cs=null;
}
if (c != null){
c.close();
c=null;
}
System.out.println("Se desconecto de la bd");

} catch (Exception e) {
System.err.println(e.getMessage());
}
}

Jboss said:
[org.jboss.resource.connectionmanager.LocalTxConnectionManager$LocalConnectionEventListener] throwable from unregister connection
java.lang.IllegalStateException: Trying to return an unknown connection1!

What can I do to solve this problem? I read many solutions, but I can't solve my problem, I use Jboss 3.0.7 an SQL Server 2000, and I didn't find the transaction-server.xml file

Help me please!!
Thanks at all!!
