处理办法

 在Tomcat Server 配置中添加下面内容

-Dcatalina.base="D:\workspace-jee\.metadata\.plugins\org.eclipse.wst.server.core\tmp0" -Dcatalina.home="D:\middlesoftware\tomcat7" -Dwtp.deploy="D:\workspace-jee\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps" -Djava.endorsed.dirs="D:\middlesoftware\tomcat7\endorsed"

-server -Xms800m -Xmx800m -XX:PermSize=128M -XX:MaxNewSize=256m -XX:MaxPermSize=256m -Djava.awt.headless=true
