6 个解决方案

#1

jar/类 太多了

http://blog.csdn.net/fengyie007/article/details/1780375

#2

这个有什么解决的办法吗？

#3

今天试着去做东西的话  是这样 页面不会报错  但是程序依然是报出空指针异常……页面跳转也成功了  提交的时候依然会报出上面的空指针异常，我新建了一个工程环境  然后用svn从新检索出这个项目 这次是页面不报错了  但是问题是 成依然报出空指针异常，这 该如何解决呢？

#4

空指针异常 Debug一下就知道了

#5

我这的程序都有debug   关键是具体的异常报不出来

#6

这里面是两类错误，并不一样。


永久区内存溢出是一类错误，参见：

空指针错误：
java.lang.NullPointerException
 at com.icss.ro.starflow.organization.impl.WfHumanImpl.getMobile(WfHumanImpl.java:152)

检查WfHumanImpl.java程序的 152 行代码。
