Ok, I tested this this morning and it is working great. The idea here is to add this action class to your config and set the url of the application tag to the /ajax action. Your application class's method will get invoked and if it returns an ActionForward the result of the path in that forward will be return to your javascript call, otherwise you can just return and object.
This goes back to the discussion of adding the xoscript flavor of ajax to struts, here is the quick view to the changes in the set up configuration explained here. http://www.xoscript.org/opencms/opencms/documentation/setupconfig.html 1. You would not need to declare the XSOServlet, the ActionServlet would be all that is needed. You will need the xso.jar from the site above 2. Set the url of the application to the AjaxAction class below. and import the main class for your application and optionally other imports if needed. <xso:Application excludescript="true" servleturl="http://localhost:8080/webexit/ajax.do";> <xso:Import name="main" object="com.yourcompany.app.Main"/> </xso:Application> 3. Add the AjaxAction to your struts config. <action path="/ajax" scope="sessioin" type="com.yourcompany.struts.action.AjaxAction" validate="false"></action> 4. In your Main class you will have the option of returning an object of any kind to the javascript call to it's methods or if you return an ActionForward the action servlet will get the result of that path associated with that action and return it to your javascript as a string. public class Main { public ActionForward getTestPage() throws Exception{ ActionForward forward = new ActionForward(); forward.setPath("/test.jsp"); return forward; } } 4. The javascript veriable main will now contain the resulting content of test.jsp Here is the AjaxAciton class. package com.yourcompany.struts.action; import javax.servlet.RequestDispatcher; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.apache.struts.action.Action; import org.apache.struts.action.ActionForm; import org.apache.struts.action.ActionForward; import org.apache.struts.action.ActionMapping; import org.xoscript.server.HttpMetaData; import org.xoscript.server.HttpMetaRequestWraper; import org.xoscript.server.HttpMetaResponseWraper; import org.xoscript.service.LogFactory; import org.xoscript.service.LogProvider; import org.xoscript.service.ProxyObject; import org.xoscript.service.ProxyObjectFactory; import org.xoscript.service.XOService; import org.xoscript.service.XOServiceFactory; public class AjaxAction extends Action { private static LogProvider log = LogFactory.getLogProvider(); private static XOService xoService = null; public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { ActionForward forward = null; if (log.isInfoEnabled()) { log.info("begin processRequest ------------------------------>: "); } try { /** * The (POJO)'s method call invoked by xoService below * can retrieve this meta data object from the * XOServiceFactory to get information about the * request and response objects */ xoService = XOServiceFactory.getService(); HttpMetaData metaData = new HttpMetaData(); response.setContentType("text/xml; charset=ISO-8859-1"); metaData.setRequest(request); metaData.setResponse(response); metaData.setContext(null); XOServiceFactory.setMetaData(metaData); /** * The xml is read in and a ProxoyObject is created. * The ProxyObject now contains the lookup information * for the POJO and what method and argument should be * invoked.
