Cannot resolve package json-default, hibernate-default

[Gagan Grover]

Hi,

I have struts.xml (Struts 2) file as shown below

<struts>

  <constant name="struts.enable.DynamicMethodInvocation" value="false"/>
  <constant name="struts.devMode" value="true" />

  <package name="reports" namespace="/reports" extends="json-default, hibernate-default">

    <action name="ShowReportList" class="com.ql2.reports.actions.ShowReportList" method="initializeReportList">
      <result>/pages/ReportList.jsp</result>
    </action>

    <action name="ShowReportInputParams" class="com.ql2.reports.actions.ShowReportInputParams" method="initializeReportObjects">
      <result>/pages/ReportInputParams.jsp</result>
    </action>

    <action name="SaveAndViewReport" class="com.ql2.reports.actions.SaveAndViewReport" method="saveAndViewReport">
      <result>/pages/ReportTableau.jsp</result>
    </action>

    <action name="GetContextFilterData" method="extractData" class="com.ql2.reports.actions.GetContextFilterData">
      <result type="json" />
    </action>

  </package>

</struts>

But in this xml the line extends="json-default, hibernate-default" is coming in red with error "Cannot resolve package json-default, hibernate-default". I have put the plugin jars for both in the lib folder, these jars are struts2-fullhibernatecore-plugin-2.2.2-GA.jar, struts2-json-plugin-2.1.8.jar and i have associated there plugin xmls in Struts2 facets in project settings. Also, if I use either of them in the extends attribute this error does not come. I am using Intellij Idea as the IDE for development.

Are there any other settings that needs to be done other than those described above or what can be solution to this problem?
