JMX监控weblogic

今天尝试着测试一下Weblogic 11g的MDB功能，发现尽管引入了weblogic.jar，可是仍然有很多J2EE的Class找不到。我本地没有安装Weblogic，只好一个类库，一个类库的找。后来在网上发现，原来在Weblogic 10以后，应该使用wlfullclient.jar来取代weblogic.jar。可以使用下面的办法生成wlfullclient.jar。

1. Change directories to the server/lib directory.
cd WL_HOME/server/lib

2. Use the following command to create wlfullclient.jar in the server/lib directory:
java -jar wljarbuilder.jar

3. You can now copy and bundle the wlfullclient.jar with client applications.

4.classpath加入wlfullclient.jar

5.测试代码
