Hi,


atm I try to understand OPS (a nightly built of 03.01.2007) in combination with liferay portal.
Liferay works well and I implemented some demo jsp portlets and deployed them successfully.

I also were able to run some of the orbeon examples as portlet, but not all. I think I did not understand the deployment mechanism completly.



So here some questions (I know this are a lot. So please tell me, if I should open several threads)



1. Deployment

        After installing liferay I had several folders in the webapps folder. I think "ROOT" is the important one.
        I deployed the ops.war so ops runs as normal (localhost:8080/ops)

        To deploy an ops portlet I defined it in the portlet.xml and web.xml of ops and added
        <portlet>
              <portlet-name>OrbeonTestPortlet</portlet-name>
        </portlet> in  liferay-portlet-ext. xml

        Is this the common way of deployment or should I deploy the ops.war with hot deploy functionality of liferay (which did not work when I tried)?



2. Defining and using Orbeon applications as portlets

        As mentioned above easy deployment of existing ops applications were only possible with some.

        - Examples where "path-info" is set to"*" or "/" in the pageflow.xml works fine (f.e. <page path-info="*" view="calc.xhtml"/> of calculator application)

        - In the TODO example I had to change
                <page path-info="/xforms-todo/" view="view.xhtml"/>
                to
                <page path-info="/" view="view.xhtml"/>

                The page info <page path-info="/xforms-todo/format-instance" view="format-instance.xpl"/> I did not touch.

                Otherwise a "Condition failed for every branch of choose" error occurs.
                But the gif's, defined in the view.xhtm I can not see. Seems to me that a path like src="../apps/xforms-todo/images/edit.gif" does not work.

        - the "forms" example did not run at all. Changing the path-info to "/" or "*" did not help. I even do not know, which path-info I should change there.


        How does the path-info mechanism works? Did I specify something wrong? The only place where a reference to the pageflow.xml is set is inside the portlet tag in portlet.xml

         <init-param>
                    <name>oxf.main-processor.input.controller</name>
                    <value>oxf:/apps/forms/page-flow.xml</value>
         </init-param>




4. How can I achive the following?

        I want to write a portlet with following functionality.
        My portlet should appear in the main portal window holding informations of the latest tasks a user has to do next. When the user clicks on a task, a full sized window appears, where he can insert         some comments etc..
        There should be also a  redirect button to the main portal page.

        What is the best way to achieve this? I have two ways in mind but dont know which one works or which is the best.

        1. I write two portlets. One for the tasklist, one for the details. The problem is, how the portlets can communicate. I read that jsr-168 can not communicate between each other. I this right? Is it also not                 possible that one portlet leads to another?

        2. I write one Portlet and deploy it inside the main window. I click on a task opens just a new window. Sounds pretty easy but I dont know how navigate back to the main portal window?



Many thanks for all answers

Best regards

Sebastian Kraus
