Liferay 6: OpenSocial Gadgets

Michael Young

Less Than a Minute Read

Liferay 6 will feature an OpenSocial container based on Shindig. OpenSocial Gadgets present as first-class citizens via the "Add Application" menu, just like portlets.

To configure a Gadget in Liferay, all you need is the Gadget URL. In the screenshots below I've configured three gadgets:

http://www.labpixies.com/campaigns/todo/todo.xml
http://www.google.com/ig/modules/horoscope.xml
http://localhost:8080/opensocial-portlet/gadgets/files/samplecontainer/examples/SocialHelloWorld.xml (this is a sample Shindig gadget)

Micheal, thanks for the info. Where does the data get saved when you use the new Gadget feature in Liferay?

Please sign in to reply.

Hi Philip, the portlet opensocial-portlet has its own database table to save the data (name and URL) as

create table OpenSocial_Gadget (
gadgetId LONG not null primary key,
companyId LONG,
createDate DATE null,
modifiedDate DATE null,
name VARCHAR(75) null,
url STRING null
);

Hope that it helps,

Thanks

App data is saved via Expando on a per user / per app basis.

Nice feature! emoticon

Are open social gadgets for portal instance or portal wide, like themes?

Please sign in to reply.

Hi Jader, open social gadgets are portal-instance wide, since company-Id is one of fields. right?

I have downloaded LR 6 Beta CE, logged in as Bruno, but do not see this feature. Am I missing something ?

Thanks

Hi Tony, you need deploy opensocial portlet first.

You can find the portlet (opensocial-portlet-6.0.2.1.war) at http://liferay.cignex.com/palm_tree/book/0387/chapter12/.

Hope that it helps,

Thanks

Really nice feature. I just testing it and seems to work out of the box.
Well, i tried changing the view, and seems that feature is not yet available. do you have plans for his feature?

Carlos,

Thanks for checking that out. We're going to implement the views very soon. Which gadget(s) are you testing with?

Please sign in to reply.

Just testing some copy&paste examples.

I testing OpenSocial because i'm thinking about to integrate a .NET application with strong AJAX background an OpenSocial fits nicelly with that kind of integration.

It would be desirable also, the possibility available on regular portlets of redirect the view change to another page.

Really, i think that Liferay becames a OpenSocial container gives it a great future. OpenSocial overlaps in many ways Portlet specification, but the development lifecicle is fas simple. I'm really excited about it.

Gadgets now running in LifeRay :-) However they are removed when LifeRay is restarted. The portlet frame is left behind with following message in the content area:

'This portlet has been undeployed. Please redeploy it or remove it from the page.'

Please sign in to reply.

the same problem than Tony, when you restart the server the gadget dissapear from the add menu and the portlet is not available in the pages.

I'm testing in Liferay 6 RC2. the message is "Portlet is temporarily unavailable." and a nullpointer appears in the console.

Hi Unai, thanks. This is a bug. I can reproduce the same. You may report this in JIRA.

I want to add a gadget dinamically from another application. What is the better way to do it?

Very nice and interesting feature . Thank You emoticon

Does this gadget work on Liferay 6.0 ? Because I can't use it on my Liferay's version....

I deployed the opensocial-portlet-6.0.2.1.war file (from the download link posted by @Jonas) on my liferay-6.0.4 bundled installation. I got the following error message in my server log. Sorry, I have to paste the log file content as I cannot attach it in the post.

Possibly a dumb question but I have been googling for 30 min to find a directory of open social gadgets... anyone know where they are?

Please sign in to reply.

I created an OpenSocial gadget (6.0.6.1) with the URL that contains https and got an exception:

08:36:54,853 ERROR [PortletServlet:96] javax.portlet.PortletException: org.apache.shindig.gadgets.process.ProcessingException: javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated

at com.liferay.opensocial.portlet.GadgetPortlet.render(GadgetPortlet.java:88)
at com.liferay.portlet.FilterChainImpl.doFilter(FilterChainImpl.java:101)
.....
does anyone know what to be defined so that OpenSocial gadget can handle seccured URLs?

Thanks

Has anyone integrated Jira and Liferay using OAuth?

I created public/private key using keytool and exported the certificate into rsaSigningKey.pem. Placed this file in liferaydatafolder/opensocial/.

Configured Incoming authentication in Application Links of Jira with

Consumer key - www.myliferay.com

Consumer Name - Liferay

Public key - public key text from rsaSigningKey.pem file.

Public key greyed out and saved the configuration.

Added the OpenSocial gadget onto the Liferay page. Gave the url of activityStream of Jira and in Manage OAuth section selected RSA_private and gave the consumer key as www.myliferay.com. Saved the configuration.

My activity stream in Liferay shows empty. When I checked the liferay console, it shows an error of jodd.bean.BeanException: Simple property not found: oAuthConsumerId Invalid property: 'OAuthConsumerImpl#oAuthconsumerId (actual: 'OAuthConsumerImpl#oAuthConsumerId', forced=false)

Where am I going wrong? should the consumer key be the CN of public/private key creation?

Kicha
