I am using Weblogic 8.1. I have created connection pool and datasource both successfully. But at the time of getting connection through jsp its giving following error

java.lang.NoClassDefFoundError: weblogic/jdbc/wrapper/PoolConnection

java.sql.SQLException: Cannot obtain connection: driverURL = jdbc:weblogic ool:
My Pool, props = {enableTwoPhaseCommit=false, jdbcTxDataSource=true, connectionP
oolID=My Pool, dataSourceName=ejbPool}.
Nested Exception: java.lang.RuntimeException: Failed to Generate Wrapper Class

JSP code:

Context ctx = new InitialContext();
DataSource ds = (DataSource) ctx.lookup("ejbPool");
Connection con = ds.getConnection();
if(con != null)
out.println("Connection established successfully...");
out.println("Something wrong");

Rajkumar, make sure that weblogic.jar file is in class path.
