消息驱动bean的发布问题

[zuoyangguang]

消息驱动bean发布的时候，报如下错误：
java.lang.NullPointerException

我配置了connection factories,stores,和servers,我的weblogic是8.1的。

java.lang.NullPointerException
明显是空指针异常，光看错误信息别人也不知道你哪里错了

[zuoyangguang]

我在jbuilder下配置的weblogic8.1,然后利用向导作了一个消息驱动bean,在onMessage方法下加了如下代码，然后就编译，发布，就出现上述错误。
if(msg instanceof TextMessage){
TextMessage tm=(TextMessage)msg;
try {
String text=tm.getText();
System.out.println(new StringBuffer().append("Received new message:").append(text) );
}
catch (JMSException ex) {
ex.printStackTrace();
}
}
