struts2-rest plugin..making both struts actions + rest actions work together but. giving java.lang.reflect.InvocationTargetException

rest, struts, struts2-convention-plugin

Solution

ive solved the problem with customMapper..

this is my custom mapper class....

   package org.apache.struts2.rest.example;

    import javax.servlet.http.HttpServletRequest;
    import org.apache.struts2.dispatcher.mapper.ActionMapper;
    import org.apache.struts2.dispatcher.mapper.ActionMapping;
    import org.apache.struts2.dispatcher.mapper.DefaultActionMapper;
    import com.opensymphony.xwork2.config.ConfigurationManager;

   public class CustomActionMapper extends DefaultActionMapper {


    public ActionMapping getMapping(HttpServletRequest request, ConfigurationManager configManager) {

        return getActionMapper(request, configManager).getMapping(request, configManager);

    }

    private ActionMapper getActionMapper(HttpServletRequest request, ConfigurationManager configManager) {

        ActionMapping actionMapping = new ActionMapping();  

        parseNameAndNamespace(request.getRequestURI(), actionMapping, configManager);

        if (!(actionMapping.getNamespace()).contains("/rest")) {

            return container.getInstance(ActionMapper.class, "struts");

        } 
        else 
        {
            return container.getInstance(ActionMapper.class, "rest");


}
}

........................................... my struts.xml is as follows......

<?xml version="1.0" encoding="UTF-8" ?>


  <!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">
