用DataSource就不行，我的code：

public Connection getConnection(){

Connection con = null;

DataSource ds = null;

try{

InitialContext ctx = new InitialContext();

System.out.println("ccccccccccccccccc");

ds = (DataSource)ctx.lookup("java:comp/env/estore");

System.out.println("dddddddddddddddd");

con = ds.getConnection();

System.out.println("eeeeeeeeeeeeeeeeeeeee");

}

catch(Exception e){

e.printStackTrace();

}

return con;

}

执行不到System.out.println("eeeeeeeeeeeeeeeeeeeee");

抛出的异常：

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

java.sql.SQLException: Cannot obtain connection: driverURL = jdbc:weblogic:pool:estoreConn

ectionPool, props = {enableTwoPhaseCommit=false, jdbcTxDataSource=true, connectionPoolID=e

storeConnectionPool, dataSourceName=estoreDataSource}.
