tomcat启动时出错

Question

java.lang.reflect.InvocationTargetException异常 在 sun.reflect.NativeMethodAccessorImpl.invoke0(本地方法)

在myeclipse中启动tomcat 5.5.x服务器出现上述错误。

实际上我已经在我的 32 位 Windows 机器上检查并编译了它。现在，当我备份我的 tomcat 并结帐并尝试在 Windows 7 64 位中启动时，我遇到了错误。任何人都可以提出问题所在。下面是完整的堆栈跟踪。

Caused by: java.lang.OutOfMemoryError: PermGen space

Answer 1

这里的重点是

Caused by: java.lang.OutOfMemoryError: PermGen space

我的第一个有根据的猜测是您的 PermGen 内存不足。网上有很多关于如何处理的信息(包括 stackoverflow )，所以我不会在这里重复解释。
