Hi there,
I am trying to get the ajax push to work with the liferay but haven't been able to update multiple client browser running on different machine.
Please take a look @ the code and provide me some direction

I am using icefaces 1.8.2 with liferay 5.2.3 on GLASSFISH 2.1 on windowsXP.
push server.war is install and in the log all i see is this message

20:35:30,105 INFO [RenderHub:238] core render service created:

Anyone ? or anyway from icefaces ?

thanks

Can you successfully build and deploy on of the portlet examples that come with the ICEfaces distributions? There are a couple under [icefaces.dir]/samples/portlets.

There is also an introductory Ajax Push tutorial online that you walk through. It's not specific to portlets but it might be helpful:
http://facestutorials.icefaces.org/tutorial/easy-ajax-push.html

One thing in your code is that that you're adding the Renderable bean in what looks like an Update actionListener. This means that the bean will not be added to the render group until that actionListener is triggered (ie clicking a button). If you want the bean added to the group when the bean is created, you should move that logic to the setter where the RenderManager is injected.

hi deryk,
thanks 4 ur reply.
I did take a look @ the tutorial u mentioned and some of the other tutorials on ajax push... they all provide the same code mechanism. I 'm just wondering if icefaces 1.8.2 and liferay 5.2.3 work fine when using ajax push.... is there any setting or configuration that i maybe missing....

???

Hi deryk,

So after further investigation I found out that this is what is generated by the icefaces push when i try to send the updates to client browser.

<updates>

<update address="_Monitor_WAR_Monitor001SNAPSHOT_INSTANCE_qF6v_:iceform:j_id14" tag="span">

<attribute name="class"><![CDATA[iceOutTxt]]></attribute><attribute name="id">

<![CDATA[_Monitor_WAR_Monitor001SNAPSHOT_INSTANCE_qF6v_:iceform:j_id14]]>

</attribute>

<attribute name="style"><![CDATA[line-height:2em]]></attribute><content><![CDATA[2010-06-17 01:18:03.998]]></content>

</update>

</updates>

<<<<<![CDATA[2010-06-17 01:18:03.998]] >>>>>> is the time stamp i want to send to client browser using ondemand renderer

However client browser does not get updated with the icefaces push

Hope that you would be able to provide me direction.

The update looks about right so perhaps it's not getting applied due to some other error. Are you using a browser that has a JavaScript console of some kind (ie Firefox + Firebug or Chrome) that would log a problem?

You can also try CTRL-SHIFT-T to bring up the ICEfaces client console and see if it logs anything.

Besides that, you could post a simple example of your portlet .war for us to look at.

Hello deryk,

I created 2 portlets based on Icefaces push technology. Each portlet is on a different WAR file.
If i deploy only one WAR file. The portlet works well. If i deploy 2 WARs file in Liferay the portlets will not work properly(ajax push not working) althrough i already deployed Push Server Comunity server.

To test my assumtion. I packed 2 portlets in only one WAR file and they work.

My server is Tomcat 6 and already deployed in NIO mode.

It seems that i have to deploy AHS to make 2 WAR files work

Could you tell me where i am wrong here?

Thanks you

Hi Deryk:
Sorry for replying you back so late. I had to build a simple sample war for you and in doing so I ran into another issue.
Anyway here is the output from the google chrome browser. I don't see any error in the server log file however I don't see
the updates in the second browser after clicking the update button.

Output is listed below with the screen shot and sample war file.

My portlet crashes if I put the addbtn logic in the request bean constructor method that's why i had to put it in the btn event.

Server Output is given below when these two lines are added in the constructor

stockGroup = renderManager.getOnDemandRenderer( "DynamicGroupName" );
stockGroup.add(this);

Server Output

Let me know if you require additional information

Hello,

Anyone helps me out of this error?

I followed the trace and looked at com.icesoft.util.ServerUtility.java

The code that causes the error is:

if (_serverInfo.startsWith("jetty")) {
136 _servletContextPath =
137 _path.substring(
138 _path.indexOf("__") + 2,
139 _path.lastIndexOf("__"));
140 }

Can anyone helps me out of this?
