Tomcat catalibnna.bat start闪退问题 Error starting static Resources java.lang.IllegalArgumentException:

1 出现“catalibnna.bat start”闪退，不要怕，先找问题

输入: 在命令行中输入：catalibnna.bat run 会在出现错误后停止，而不是退出，这样我们可以看到问题，方便解决

CATALINA_HOME,JRE_HOME 保证路径正确就可以（这两个路径不正确，也会闪退）

C:\Users\Administrator\Desktop\apache-tomcat-7.0.63-cas\bin>catalina.bat run

C:\Users\Administrator\Desktop\apache-tomcat-7.0.63-cas\bin>set JAVA_OPTS=-Xms51

Using CATALINA_HOME:   "C:\Users\Administrator\Desktop\apache-tomcat-7.0.63-cas"

3 原因是什么？删除CAS(我自己的项目名称)：C:\Users\lele\Desktop\apache-tomcat-7.0.63-cas\work\Catalina\localhost中的文件不干净，没有删除相应配置文件。

打开tomcat安装目录中 /conf/server.xml文件 发现：有一个cas在那里存在着。。。

<Context docBase="cas" path="" workDir="work/Catalina/localhost/cas" reloadable="true"/>

注释上面这句话（你的可能是其他的项目），然后重新启Tomcat就OK了。
