今天打开Myeclipse10的时候，发现server窗口出现一堆问题，问题如标题，然后下方出现了一堆java.lang.NullPointerException的问题。

java.lang.NullPointerException

这个问题的出现是在启动myeclipse之后出现的，这时还没有启动tomcat，因此可以排除tomcat中项目代码问题。应该是myeclipse在初始化工作空间workspace 的时候

出的问题。

仔细看下错误发现有一条 at
com.genuitec.eclipse.ast.deploy.core.Deployment.这个错误，于是到工作空间下面的
D:\Workspaces\.metadata\.plugins\org.eclipse.core.runtime\.settings目录下面找
到了名称为at
com.genuitec.eclipse.ast.deploy的prefs文件，打开文件一开，哈哈，原来里面都是原来的一些项目信息，怪不得会报
java.lang.NullPointerException错误呢。果断将此文件删除，重启myeclipse10问题解决
