Ofbiz service call from GWT RPC

[Gintare Ragaisiene]

Hello,

   I'm working on tintegration GWT into ofbiz. GWT compiled js files is
placed into ofbiz "images" component in order ftl access them:

gwt_test.ftl

  <script type="text/javascript" language="javascript"
src="/images/gwttest1/gwttest1.nocache.js"></script>
  <table align="center">
      <tr>
        <td colspan="2" style="font-weight:bold;">Please enter your
name:</td>
      </tr>
      <tr>
        <td id="nameFieldContainer"></td>
        <td id="sendButtonContainer"></td>
      </tr>
    </table>

   Then I access GWT RPC from javascript. For this I corrected "images"
component war, because javascrip searches for servlet with path
"/gwttest1/greet" :

framework/images/webapp/images/war.xml :

<web-app>
  <display-name>Open For Business - demostore images</display-name>
  <description>Demo Store Images for the Open For Business
Project</description>

  <servlet>
    <servlet-name>greetServlet</servlet-name>

<servlet-class>org.ginsoftware.server.GreetingServiceImpl</servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>greetServlet</servlet-name>
    <url-pattern>/gwttest1/greet</url-pattern>
  </servlet-mapping>

  <session-config>
    <session-timeout>1</session-timeout>
  </session-config>

  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>main.jsp</welcome-file>
  </welcome-file-list>

</web-app>



    And I implemented servlet it self GreetingServiceImpl.java and classes
is put into images/WEB-INF :

   public class GreetingServiceImpl extends RemoteServiceServlet implements
GreetingService {

       public String greetServer(String input) {

            //Haw to call ofbiz service ?

            String serverInfo = getServletContext().getServerInfo();
            String userAgent =
getThreadLocalRequest().getHeader("User-Agent");

            return "Hello, " + input + "!<br><br>I am running " + serverInfo
+ ".<br><br>It looks like you are using:<br>" + userAgent;

       }
    }


    Until now everything works fine and my question is how do I call ofbiz
service from greetServer() method ? I've tried obtain LocalServiceDispacher
in variuos ways, but no luck at all.

Or is there somebody who already did that integration in more convenient way
that me ?


Thanks,

I would suggest you to go with a xml-rpc way.
Explore XmlRpcTests.java & XmlRpcClient.java files.

You can export services to external world by setting service definition
export attribute to true.
Take a look at the service definition "testScv" for more details.

OFBiz has XML-Rpc client and server inbuilt in it.
So you can see the output generated by XmlRpcTests.java file by following
command on console.

java -jar ofbiz.jar -test

Check block : "Running OFBiz Automated Tests" in the below document.

Hi.

I am also toying with integrating GWT and Ofbiz. Using rpc calls available
in Ofbiz (xml, soap or json) does work with GWT with not much problem. My
problem is that I dont want to make all the services I need in Ofbiz to be
publicly available. Is there a way to make a service available for RPC but
would limit it to specific IPs only? Or is my concern unnecessary?

Regd integration.

Approach we took was:
ofbiz does not have GWT native RPC support but it can do JSON and Http/XML more easily.
Use http/JSON RPC instead of GWT Native RPC + GWT serialization.


Regd getting LocalServiceDispacher
You should be able to do:
        LocalDispatcher dispatcher = (LocalDispatcher) request.getAttribute("dispatcher");
        result = dispatcher.runSync(...)
LocalDispatcher is set in ControlServlet.
ControlServlet is in each web.xml
    <servlet>
        <servlet-name>ControlServlet</servlet-name>
        <display-name>ControlServlet</display-name>
        <description>Main Control Servlet</description>
        <servlet-class>org.ofbiz.webapp.control.ControlServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>ControlServlet</servlet-name>
        <url-pattern>/control/*</url-pattern>
    </servlet-mapping>

Note Load on startup and that your URLS will have /control/ i.e. loading ControlServlet.
Make sure your control servlet is loaded or look at how ofbiz is setting things in ControlServlet. Perhaps override if you cannot use ControlServlet configuration as is.
