This error is most likely caused by one of the following:
  • You faled to speciffy <load-on-startup>2</load-on-startup> for the Struts ActionServlet in your web.xml file
  • You did specify the above, but the Struts ActionServlet didn't initialize properly because of an error. Check the log file entries for the time period when the Server first starts up to see if it initialized properly.

    If you look closely at the stack trace, it's telling you very specifically what's wrong: Struts can't parse the XML in your struts-config.xml file

    Is what you posted the entire contents of your struts-config.xml file? If so, it's pretty clear why Struts can't parse it: It doesn't follow the format required by the DTD.

    It's really better if you don't try to build your struts-config.xml file from scratch. I'd recommend starting from the template provided in the struts-blank.war file that comes with the Struts download.

    Here's what I recommend:
  • Rename your current struts-config.xml file to some other name
  • Find the struts-blank.war file that came with the download
  • Unzip the file into a directory on your disk somewhere
  • Copy the sample struts-config.xml file in the WEB-INF directory to the same directory in your application
  • Copy and paste the <form-beans> and <action> stanzas from your old renamed file into the new struts-config.xml file and delete the sample ones that are already there
  • There's one problem you need to make sure gets corrected in the new version of the config file: All <action> stanzas must be enclosed in a single <action-mappings> stanza
  • Redeploy the application and retest

    what about Action servlet. Is it one of the reasons that error has occured.
    Because I could see everything goes fine until the action servlet is encountered, in the log file. for your information, in the log file
    localhost.2007-03-08.log, we can see this piece of errror message,

    INFO: Marking servlet action as unavailable
    Mar 8, 2007 11:42:55 AM org.apache.catalina.core.StandardContext loadOnStartup
    SEVERE: Servlet /test threw load() exception


    and in catalina.2007-03-08.log ,

    Mar 8, 2007 11:42:55 AM org.apache.struts.action.ActionServlet initChain
    INFO: Loading chain catalog from jar:file:/E:/dhamu/kicha/Tomcat6.0/webapps/test/WEB-INF/lib/struts-core-1.3.5.jar!/org/apache/struts/chain/chain-config.xml
    Mar 8, 2007 11:42:55 AM org.apache.commons.digester.Digester fatalError
    SEVERE: Parse Fatal Error at line 2 column 6: The processing instruction target matching "[xX][mM][lL]" is not allowed


    so does Action servlet had something to do with the error?

    The reason the ActionServlet is unavailable is that it didn't initialize properly when the server started up. In order to become active, the ActionServlet must perform its initialization logic, part of which is to read and parse the struts-config.xml file. The following part of the stack trace tells you very specifically that the ActionServlet was trying to perform it's init method, but ran into an error when it tried to parse the struts-config.xml file.
