Hi All,
I am getting Null PointerException when i tried to view my login page.
Struts is not able to find the message resources.
This is configuration in my struts-config.xml
<message-resources parameter="security" null="false"></message-resources>
i am getting
java.lang.NullPointerException at
org.apache.struts.taglib.TagUtils.retrieveMessageResources(TagUtils.java:1174)
at org.apache.struts.taglib.TagUtils.message(
TagUtils.java:1037) at org.apache.struts.taglib.bean.MessageTag.doStartTag(
MessageTag.java:224) at
jsp_servlet._content._jsp.__login._jspService(__login.java:161) at
weblogic.servlet.jsp.JspBase.service(JspBase.java:33)
I have attached the struts source i and i found it is happening in the
following line of TagUtils class
----
if (resources == null) {
ModuleConfig moduleConfig = getModuleConfig(pageContext); //
Returns Null !!
resources =
(MessageResources) pageContext.getAttribute(
bundle + moduleConfig.getPrefix(),
PageContext.APPLICATION_SCOPE);
}
While debugging, it is returning the ModuleConfig as null. I dont' know why
it is trying to get the module config even though i haven't configured any
struts module.
This is my web.xml
