weblogic JMX 中遇到的问题

通过JMX操作来监控weblogic jdbcpool实例如下
package weblogic;
import java.util.*;
import javax.management.*;
import weblogic.management.*;
import weblogic.management.configuration.*;
import weblogic.management.runtime.ServerRuntimeMBean;
import weblogic.management.runtime.JDBCConnectionPoolRuntimeMBean;

public class TestJMX {

/**取得当前weblogic server 的jdbcconnectionPool
* @param args
*/

public MBeanHome localHome;
public MBeanHome adminHome;
public Stack stack;
public static String SERVER_NAME="myserver";
public Stack find()
{
stack=new Stack();
String url="t3://130.30.15.44:8080";
//其中t3 是protocol
localHome = (MBeanHome)Helper.getMBeanHome("weblogic","weblogic",url,SERVER_NAME);
adminHome = (MBeanHome)Helper.getAdminMBeanHome("weblogic","weblogic",url);
Set set1 =adminHome.getMBeansByType("JDBCTxDataSource");
Set set2 =adminHome.getMBeansByType("JDBCDataSource");
Iterator it1 = set1.iterator();
while(it1.hasNext()){
JDBCTxDataSourceMBean dm1 = (JDBCTxDataSourceMBean)it1.next();
System.out.println("%%%%%%%%%%%"+dm1.getJNDIName());
stack.add(dm1.getJNDIName());
}

Iterator it2 = set2.iterator();
while(it2.hasNext()){
JDBCDataSourceMBean dm2 = (JDBCDataSourceMBean)it2.next();
System.out.println("%%%%%%%%%%%"+dm2.getJNDIName());
stack.add(dm2.getJNDIName());
}

return stack;

}

public static void main(String[] args ) {
TestJMX test=new TestJMX();
test.find();
}
}
我访问的是weblogic 8 我的jdk 是1.6
附：请导入weblogic.jar编译出错如下
