Hi,

I have been trying to  Orbeon with one portlet in liferay.

Does anyone know which is the cause of the problem I am having?

I have been following this guide: http://wiki.orbeon.com/forms/doc/developer-guide/xforms-separate-deployment-with-portlets

After following all these steps, I got a block of words in my portlet. Thanks to Stian, I found out that, the problem was that I was using .jsps, and there are some limitations with that.

But now, after doing some changes, I get this error, and when I deploy my portlet in liferay, it says: OrbeonTestXFormPortlet is temporarily unavailable.

I get this error:

INFO: Server startup in 99515 ms
09:33:17,075 ERROR [PortletRequestDispatcherImpl:93] javax.servlet.ServletException: Can't find Orbeon Forms context called '/orbeon'. Check the 'oxf.xforms.renderer.context' filter initialization parameter and the <Context crossContext="true"/> attribute.
javax.servlet.ServletException: Can't find Orbeon Forms context called '/orbeon'. Check the 'oxf.xforms.renderer.context' filter initialization parameter and the <Context crossContext="true"/> attribute.

    at javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
....

I know (I believe) that there must be a problem with crossContext, but I can't find it.
in server.xml :

   <Host appBase="webapps" autoDeploy="true" deployXML="false" name="localhost" unpackWARs="true" xmlNamespaceAware="false" xmlValidation="false">

      <Context path="/orbeon" docBase="orbeon" crossContext="true"/>
      <Context path="/ROOT" docBase="ROOT" crossContext="true"/>

   </Host>

(ROOT is where liferay is placed, do I need to put  ROOT or the name of my portlet?)

I change that in server.xml, and every time I start my server it is remove...

I don't know what is my problem... can anyone help???

Thanks so much.

Regards,

María

Hi Maria

 

You appear to have an identical setup and are experiencing an identical problem to what I have been attempting to resolve.

 

The reason why you are just getting "a block of words" is because the OrbeonPortletXFormsFilter currently has a bug in it when used in conjunction with .jsp content like you described.

Essentially the filter believes there is no content, so what you're seeing in Liferay is the actual XForms mark-up which the filter should have converted into pure HTML/JavaScript.  (view the Liferay page source to see what I mean)

 

I've been able to work around this by simply not using .JSPs.  Instead I've written my portlet to read in a {someform}.xhtml file and write() this to the Portlet's RenderResponse like this:

 

File includeFile = new File(getPortletContext().getRealPath("/html/orbeontestxformportlet/someform.xhtml"));     
FileReader includeFileReader = new FileReader(includeFile);         
PrintWriter respWriter = renderResponse.getWriter();

int byteInt;
while((byteInt = includeFileReader.read()) != -1) {
 respWriter.write(byteInt);
} 

Hope this is a viable workaround for you too, until the underlying issue with Orbeon is fixed.

This issue was recently documented in the Wiki @ http://wiki.orbeon.com/forms/doc/developer-guide/xforms-separate-deployment-with-portlets (See "Limitations" section)

 

P.S. If you discover a way of using .JSP output then I'd be very interested in hearing how you did it as this is a long term requirement for me too.

Subject: [ops-users] Re: Re: XForms in a portlet

Thanks, Erik.

I am using a nightly build (yesterday's, I think). I have deployed it in /jboss-home/server/default/deploy. I've tested Orbeon Form Builder, and it is working properly (I am able to create new forms, etc...)

On the other hand, I create a Liferay portlet (with Liferay SDK in Eclipse). I include orbeon-xforms-filter.jar in /lib. I edit portlet.xml, with this:

</portlet>
    <!-- Define the Orbeon portlet XForms filter (for handling XForms within your own portlets) -->
    <filter>
        <filter-name>orbeon-forms-portlet-xforms-filter</filter-name>
        <filter-class>org.orbeon.oxf.portlet.OrbeonPortletXFormsFilter</filter-class>
        <lifecycle>RENDER_PHASE</lifecycle>
        <lifecycle>ACTION_PHASE</lifecycle>
        <lifecycle>RESOURCE_PHASE</lifecycle>
    </filter>

    <!-- Map the Orbeon portlet XForms filter -->
    <filter-mapping>
           <filter-name>orbeon-forms-portlet-xforms-filter</filter-name>
        <portlet-name>hola</portlet-name>
</filter-mapping>
</portlet-app>

I also edit web.xml


<servlet>
        <servlet-name>orbeon-trampoline-servlet</servlet-name>
        <servlet-class>org.orbeon.oxf.portlet.OrbeonTrampolineServlet</servlet-class>
        <init-param>
            <param-name>oxf.xforms.renderer.context</param-name>
            <param-value>/orbeon.war</param-value>
        </init-param>
    <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>orbeon-trampoline-servlet</servlet-name>
        <url-pattern>/xforms-trampoline</url-pattern>
    </servlet-mapping>


Do I need to change /xforms-trampoline/ ??

The third thing I need to do is enabling cross-context. I don't know if its here where I get the error. In Jboss, which is the best way to do so?  I've added

<Context path="/orbeon.war" docBase="orbeon" crossContext="true"/>
<Context path="/liferay.war" docBase="liferay" crossContext="true"/>


in /jboss-home/server/default/deploy/jboss-web.deployer/server.xml
my-app is in this case /liferay.war?

I want to display my form in view.jsp, so here I have my xhtml code, and I would like to see the form in my portlet, but it seems difficult. The only thing I see now, is just a block of words.

Can anyone help? I would be delighted with a bit of help...

Thank you and sorry for all these questions...

Best Regards,

María
