    2005-04-05 02:24:02 StandardWrapperValve[action]: Servlet action is currently unavailable

    Here is my action tag in struts-config
    <action
    path="/userLogin"
    type="mortar.UserLoginAction">
    <forward name="success" path="/success.jsp"/>
    <forward name="failure" path="/failure.jsp"/>
    </action>
    I checked the config file with struts console it didnt generate any error.
    I've commons-beanutils.jar and struts.jar and all other jars in lib directory.
    struts examples is also not workin generating the same error. Plz help
  2. Maybe error in web.xml, as thats where your ActionServlet is configured ?

    Compare it to the web.xml in struts-blank from struts-distro!
  3. Re:Action servlet not loaded[ Go to top ]

    I faced the same problem as I was not able to call any action in my struts application after getting validated and authorized. However on checking the logs (/etc/<the directory of jakarta tomcat>/logs/catalina.out), I found that by mistake I had done multiple entries for the same attribute for an action form in struts-config.xml.
    i corrected it and it solved the problem.

    Regards
  4. Re:Action servlet not loaded[ Go to top ]

    The in every tag has to be unique. Duplicates cause tomcat not to start correctly. Regards
  5. I also faced the same problem a while ago. Pleae make sure that your all struts library (.jar) files are under WEB-INF/lib/ directory. I did the same thing and got my problem solved.
