Hi,
I am using WSAD 5.1.0 and when i tried to explore the JNDI with a simple Servlet, which connects to a MySQL database and displays some records.

After I start the WSAD, the mySQL_DS is binded to jdbc/mySQL_DS, in console :
*******************************************************************
Binding mySQL_DS as jdbc/mySQL_DS
*******************************************************************
*********** servlet code *********************************
InitialContext ctx = new InitialContext();

DataSource ds = (DataSource) ctx.lookup("jdbc/mySQL_DS");
conn = ds.getConnection("root", "fedfed");

stmt = conn.createStatement();
rs = stmt.executeQuery("SELECT * FROM USER");

*********************************************************************
When I access this servlet I get this error:
[11/26/04 18:52:41:761 GMT] 621e2e82 ConnectionFac E J2CA0036E: An exception occurred while invoking method setDataSourceProperties on com.ibm.ws.rsadapter.spi.WSManagedConnectionFactoryImpl used by resource jdbc/mySQL_DS : java.lang.reflect.InvocationTargetException: com.ibm.ws.exception.WsException: DSRA8050W: Unable to find the DataStoreHelper class specified:

Need your help on what is causing this.
Thanks and regards,
