LifeCycle DS ES communication with Web Server

[Anshul108]

Hi,

    I have written a simple Flex 3.2 code that accepts Name, uses Flext HttpService via LifeCycle DS ES 3.0. At the Server Side I am using Struts1.2 on Tomcat 5.0. My Flex code is running and Server side Struts code is running. The problem is the Name accepted on Client Side is not displaying on Server side JSP page. Below is the Client Side & Server Side code.

Client Side

hello.mxml

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

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">

<![CDATA[

public function hello1():void{

HelloCall.send();

}

]]>

</mx:Script>

<mx:HTTPService id= "HelloCall" destination= "myHello">

      <mx:request  xmlns= " " >

<mx:TextInput  id= "nameInput" x="260" y= "104" fontSize= "20" />

<mx:Button  x= "301" y= "186" label= "Submit" fontSize= "20" click= "hello1();" />

<mx:Label  x= "312" y= "285" text= "{HelloCall.lastResult.jlc.message}" fontSize= "20" />

</mx:Application>

proxy-config.xml

I believe JEE LCDS 3.0  is not supported on Tomcat 5. Also the MXML snippet put forth is malformed.

Hi Rohit,

     Yes, that seems to be one problem. Will switch to Tomcat 6.0 on web server.

Thank You.

Anshul.

Ok good.

While we are at:

[1] You haven't specified the URL for the server side JSP. E.g. The destination decl in proxy-config.xml can specify the URL as follows:

<destination id="myHello">

     <properties>

          <url>/{context.root}/testdrive-httpservice/catalog.jsp</url>

     </properties>

</destination>

Rohit

[2] The HTTPService declartion and request structures should be declared together:

<mx:HTTPService id= "HelloCall" destination= "myHello">

      <mx:request  xmlns= " " >

           <name>{nameInput.text}</name>

      </mx:request>

</mx:HTTPService>

Alright Rohit,  Here is the complete snippet, both client side & server side.

HelloAction.java
------------------

package com.jlcindia.struts;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.*;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.DynaActionForm;

import java.io.PrintWriter;

public class HelloAction extends Action{

public ActionForward execute(ActionMapping am,ActionForm af,HttpServletRequest req,HttpServletResponse res) throws Exception {

    System.out.println("Hi am here");
    DynaActionForm daf= (DynaActionForm)af;
    String name= daf.get("name").toString();
    String msg= "Hello!"+ name + "Welcome to JLC FLex LCDS with HttpService";
    res.setContentType("text/html");
    PrintWriter out= res.getWriter();
    out.println("<message>" + msg + "</message>");
    out.close();
    return am.findForward("success");
}
}

It seems that the WebServer is not receiving the message from LCDS ES Server. As I have used println statement in Action Class but noting gets printed.

Anshul, use one forum thread to track the issue. So, choose one, either this or the other one
