Jboss 啟動錯誤:InvokerServlet is privileged and cannot be loaded by this web application

在啟動Jboss 4.2 時,在載入自己開發的 web時出現下列錯誤:
Caused by: java.lang.SecurityException: Servlet of class org.apache.catalina.servlets.InvokerServlet is privileged and cannot be loaded by this web application
at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:1134)
at org.apache.catalina.core.StandardWrapper.load(StandardWrapper.java:981)
at org.apache.catalina.core.StandardContext.loadOnStartup(StandardContext.java:4069)
at org.apache.catalina.core.StandardContext.start(StandardContext.java:4366)
...以下省略

解決方式:
修改：deploy\jboss-web.deployer\context.xml
原來的：Context cookies="true" crossContext="true"
加上：privileged="true"
