Alfresco as portlet application

doblek — Mon, 10 Jul 2006 18:56:55 GMT

Hi all, I don't know where to post this message, so I apologize in advance if I post it in the wrong place. I was wondering if there is any stand-alone release of Alfresco made with portlets. In other words, can I get a release of Alfresco as a portlet application (a war file with portlets that can

In the 1.3 release of Alfresco we fixed the JSR-168 portal integration to be generic to any JSR-168 container (previously only JBoss Portal worked 100% correctly). So now it supports and run nicely within Liferay also. In theory it should work in Jetspeed as well now. I suggest you download the WAR for Alfresco 1.3 and try working out how to deploy it in Jetspeed. You will need to create the appropriate portal deployment XML files (both the JBoss + Liferay Alfresco bunldes have examples of those) which are specific to Jetspeed, but other than that in theory it should work.

You are correct that it would be best if Alfresco had native JSR-168 portlets, which it would be great if the community were interested in developing - as currently the entire Alfresco web-client is deployed as a single large portlet which is not ideal.

Thanks,

Kevin

Hi everyone!

I've procceded as Kevin suggest me but I found an error I'm not able to fix =/

I've modified the war file that it's included in alfresco-comunity-war-1.3.0.zip following somehow the instructions given in the wiki for deploying Alfresco over an existing copy of Liferay.

I've followed this steps:
1) unpack alfresco.war in temporary folder (C:\alfresco_temp)

2) delete the file portlet-api-lib.jar (which is at C:\alfresco_temp\WEB-INF\lib)

3) modify web.xml (I used the web.xml that comes with Liferay+Alfresco)

[size=75]WEB-INF/faces-config.xml[/size]

[size=75]CONFIG_FILES[/size]

[size=75]com.liferay.portal.shared.servlet.PortletContextListener[/size]

[size=75]com.liferay.portal.shared.servlet.PortletServlet[/size]

- disable servlet-mapping associated with this servlet

liferay-portlet.tld

Note: I've disabled this features because I thought they refer to Liferay libraries and I'm using Jetspeed 2[/size]

4) modify faces-config.xml (I used the one that comes with Liferay+Alfresco)
Instead of

<faces-context-factory>com.liferay.util.jsf.apache.myfaces.context.MyFacesContextFactoryImpl</faces-context-factory>‍

I use

<faces-context-factory>org.apache.myfaces.context.FacesContextFactoryImpl</faces-context-factory>‍

since I'm not sure I have the first one, and the second one lives in C:\alfresco_temp\WEB-INF\lib\myfaces-impl.jar

5) copy the portlet.xml that comes with the Liferay+alfresco

6) copy the faces_config.xml, web.xml and portlet.xml under C:\alfresco_temp\WEB-INF\

7) create the new alfresco.war

😎 deploy this new alfresco.war under the deployment folder of the portal (in my case, $TOMCAT_HOME\webapps\jetspeed\WEB-INF\deploy)

However, though jetspeed recognizes this file when it tries to deploy it, the following errors appears:

We have not tried JetSpeed ourselves so i'm only guessing here:

You may not need step 4 - it depends, does JetSpeed have a JSF bridge?

>GRAVE: connection failed: com.sun.star.connection.NoConnectException: java.net.ConnectException: Connection refused: connect
This is because you don't have openoffice server running (for document transformations) - it is not a problem.

>java.lang.OutOfMemoryError: Java heap space
What is the default JVM memory size for Jetspeed? I suggest you set it to at least 128MB and turn off any log4j debugging for Spring/Hibernate (if you have any).

Thanks,

Kevin

Hi Kevin,

Well, maybe your guesses point me to the right direction… 😃 I'm a little bit stuck =/ So I'm very thankful to you for your interest.

You may not need step 4 - it depends, does JetSpeed have a JSF bridge?

I guess it does… see this page. I took a look to the jsf sample application that comes out-of-the-box with Jetspeed2 when setting up descriptors… but I didn't get anything clear… =/
Then if there's a jsf bridge, what factory should I use??
As I can see from the logs, there is a problem initializing Listeners. Are these two issues related?? Should I "uncomment" those lines in the web.xml??

>GRAVE: connection failed: com.sun.star.connection.NoConnectException: java.net.ConnectException: Connection refused: connect

Ok.

I can't remember very well right now… but i would say it is set to 65MB and there is a log4j logger for Spring. Until this moment, I haven't had problems with this issue… but I will try.

Thanks,
Enrique

I'm not sure - it sounds like the JSF sample app is the best thing to examine. Does it have a web.xml that starts up a JSF bridge? If so then copy what it does. You may not need any! The JBoss Portal JSF bridge did not require us to have any special lines in the web.xml, but Liferay was different.

As I can see from the logs, there is a problem initializing Listeners. Are these two issues related?? Should I "uncomment" those lines in the web.xml??

No, i think they are needed.

The Spring logger may only be an issue if it's set to DEBUG. 64MB is a bit low for a portal+alfresco.

Hi,

I've been working around this thing, but with no luck… Tomcat becomes hung while (or inmediatly after) deployment.
I looked into web.xml from jsf-demo application, and Kevin was right: there is no factory definition in it. There are navigation rules, beans,… and all that stuff. But Alfresco has all these things split in different xml files, so I decided not to include de faces-config.xml (since this file only defines the factory). That not worked, so now I have an almost-empty faces-config.xml… and seems to work bit better…

In the web.xml I've modified also the class for the Alfresco Servlet to use

<servlet>
<servlet-name>AlfrescoClient</servlet-name>
<servlet-class>[size=109]org.apache.jetspeed.container.JetspeedContainerServlet[/size]</servlet-class>
    <init-param>
         <param-name>portlet-class</param-name>
         <param-value>org.alfresco.web.app.portlet.AlfrescoFacesPortlet</param-value>
    </init-param>
    <load-on-startup>0</load-on-startup>
</servlet>

instead of

<servlet>
<servlet-name>AlfrescoClient</servlet-name>
<servlet-class>[size=109]com.liferay.portal.shared.servlet.PortletServlet[/size]</servlet-class>
    <init-param>
         <param-name>portlet-class</param-name>
         <param-value>org.alfresco.web.app.portlet.AlfrescoFacesPortlet</param-value>
    </init-param>
    <load-on-startup>0</load-on-startup>
</servlet>

However, I think i keep going through some trouble because of the first listener… but I didn't find in liferay portal-ejb api any class called [size=75]PortletContextListener[/size] inside the package [size=75]com.liferay.portal.servlet[/size]. Does anyone know what is this listner for (so I can look for its equivalent in Jetspeed)?? I've found a PortletFacesContextImpl in the jsf-bridge library of J2 that maybe could work…

Thanks and regards,
Enrique

I see the Alfresco integration is never happen, because you never integrate the login between Alfresco and Liferay/JBoss Portal

I think your integration right now is useless..

but problem happen, we try to implement Liferay SSO using CAS, but Alfresco using another mechanism.

can help?

Hello, i want to do the same thing with Liferay. Can anyone help us ?

Thank you.
