Rational Rose 2003 错误解决

问题描述：

启动时报错java.lang.ClassNotFoundException，软件可以启动
在退出时报错java.lang.NullPointerException，而且软件还无法退出

解决办法：软件启动以后在工具栏-adds-in里面把Web Modeler禁用了即可。

解释：

This sounds like you have either installed an incompatible JDK on your machine (not likely as Rose works with most) or your java class path has been corrupted. The addins written in Java are Web Modeling, Data Modeling (Both based on the MSJVM), deployment, patterns, and Toplink (All three pure Java). Try disabling these addins and see if the problem goes away. You should take a look at your class path and see if it makes sense. Sometimes, if you have a lot of Java Apps on your machine, the class path can get too long and be truncated. This may have happened to your install.
