Answer 1

个人认为：XCpubSocketView.java:50 行，构造方法中有对象为空。

Answer 2

java.lang.NullPointerException
空指针异常。
然后报错的第一行也就是报错的根源，即：
    at xcpubsocket.XCpubSocketView.<init>(XCpubSocketView.java:50)确保对象不为空。

Answer 3

这个程序，放在netbeans里面，就不会报这个错了，奇怪就奇怪在这里，你们觉得是不是因为无法加载界面的原因，还是少了包~

Answer 4

不懂，帮你查了一下，参考一下，不知道对不。http://hi.baidu.com/zhuzhenping/blog/item/32630312b9978454f819b8c2.html
