在WAS上发布一个应用，报错如下：

SRVE0020E: ［Servlet 错误］－［action］：无法装入 servlet：javax.servlet.UnavailableException: CTGIMV907E An error occurred loading the SelfServiceUI.properties at org.apache.struts.action.ActionServlet.init(ActionServlet.java:368) at javax.servlet.GenericServlet.init(GenericServlet.java:258) at com.ibm.ws.webcontainer.servlet.StrictServletInstance.doInit(StrictServletInstance.java:82) at com.ibm.ws.webcontainer.servlet.StrictLifecycleServlet._init(StrictLifecycleServlet.java:147) at com.ibm.ws.webcontainer.servlet.PreInitializedServletState.init(StrictLifecycleServlet.java:270) at com.ibm.ws.webcontainer.servlet.StrictLifecycleServlet.init(StrictLifecycleServlet.java:113) at com.ibm.ws.webcontainer.servlet.ServletInstance.init(ServletInstance.java:189) at javax.servlet.GenericServlet.init(GenericServlet.java:258) at com.ibm.ws.webcontainer.webapp.WebAppServletManager.addServlet(WebAppServletManager.java:876) at com.ibm.ws.webcontainer.webapp.WebAppServletManager.loadServlet(WebAppServletManager.java:224) at com.ibm.ws.w -- <truncated> --

试图访问，ie上报错如下：
Error 503: Failed to load target servlet [action]

哪位老兄赐教一下。多谢了

这个错误比较少见，应该需要打开Web容器相关的Trace.
