[jboss-user] [Remoting] - Problem of remoting in ajax with jseam

Wed Feb 25 09:24:09 EST 2009

Hi everybody:
  I'm studying ajax in JSeam using remoting and got stuck with the helloworld demo.

  The java code:
@Local
public interface Hello {
	@WebRemote
	public String sayHello(String name);
}
@Stateful
@Scope(SESSION)
@Name("helloAction")
public class HelloAction implements Hello{
    public String sayHello(String name) {
	   System.out.println("get name:"+name);
       return "Hello, " + name;
    }

    @Remove
	public void destroy() {
	}
}

   The .xhtml:
<html xmlns="http://www.w3.org/1999/xhtml"
	  xmlns:ui="http://java.sun.com/jsf/facelets"
	  xmlns:h="http://java.sun.com/jsf/html"
	  xmlns:s="http://jboss.com/products/seam/taglib">

	<!--  tried,no use
    <s:remote include="helloAction"></s:remote>
    -->

    function sayHello() {
      var name='zwz';
      Seam.Component.newInstance("helloAction").sayHello(name, sayHelloCallback);
    }

    function sayHelloCallback(result) {
    	alert(result);
    }

  Say Hello

   The part of web.xml about jseam:

		<listener-class>
			org.jboss.seam.servlet.SeamListener
		</listener-class>

		<servlet-name>Seam Resource Servlet</servlet-name>
		<servlet-class>
			org.jboss.seam.servlet.ResourceServlet
		</servlet-class>

	<servlet-mapping>
		<servlet-name>Seam Resource Servlet</servlet-name>
		<url-pattern>/seam/resource/*</url-pattern>
	</servlet-mapping>

		<filter-name>Seam Filter</filter-name>
		<filter-class>org.jboss.seam.web.SeamFilter</filter-class>

	<filter-mapping>
		<filter-name>Seam Filter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

		<servlet-name>Seam Remoting</servlet-name>
		<servlet-class>
			org.jboss.seam.remoting.SeamRemotingServlet
		</servlet-class>

	<servlet-mapping>
		<servlet-name>Seam Remoting</servlet-name>
		<url-pattern>/seam/remoting/*</url-pattern>
	</servlet-mapping>

     The faces-config.xml :

        <view-handler>com.sun.facelets.FaceletViewHandler</view-handler>

    The components.xml :
    <core:init jndi-pattern="JSeamDemo_Remote/#{ejbName}/local"
		debug="true" />

	<core:manager conversation-timeout="120000" />

		true

      true

    The .xhtml page have javascript error, said "Seam.Component." method doesn't exist.
    I use JBoss AS 5, JSeam2.1.1,IE7.
    And I'm still confused about the code in .xhtml:

    where is the js file, which host is it on?
   Can anyone help me ?
   Thanks a lot.
