Liferay ships with a pretty old copy of Vaadin 6, but most documentation and examples out now are for Vaadin 7.  It's pretty easy to upgrade the shared Vaadin environment to Vaadin 7, as simple as installing the Vaadin 7 Control Panel from the Marketplace. When the Vaadin 7 Control Panel is installed, it will purge Vaadin 6 from the Liferay environment and copy an initial...

Are you developing a large amount of plugins? Ever found yourself frustrated with having to manually deploy war-files to development, test and production (clustered?) environments?  When performing Quality Assurance on a release it is important that it is the same build / release that is eventually deployed to production. This might sound like an easy task but...

It is a common practice to embed Web Content Articles in a theme. Once Web Content's were embedded using Web Content Display portlet, nowadays we can use journalContentUtil which is already visible for theme developers: $journalContentUtil.getContent($groupId, $articleId, $viewMode, $locale, $theme_display) As usual, there are pros and cons of this approach: It...

I previously wrote a blog entry regarding Liferay Sync and ways to authenticate the application even when using SSO (and not really having access to the SSO-password). Apparently there was interest in seeing the code and hopefully using it. I published it on Github under my employer's organization (Uppsala University).  The code is really written as a proof of concept,...

Enough reason to get together and talk about the underlying...

Why SSO? Using single sign on (SSO) is probably something that more and more systems aim towards. A large benefit is improved user experience, perhaps not so much for publically available sites. These sites generally attach to Facebook, Twitter or Google and await the crowds going 'aaaaw' in appreciation of the the techniques used.   No, instead,...

Hi everyone and Merry, Merry Christmas to all of you!  In the last couple of months I had a lot of fun playing with Go, a very promising compiled, concurrent, garbage-collected, cross-platform language by Google. I thought it would have been nice to use my newly acquired skills to build something useful for the Liferay community, and so, after my Liferay SDK for Windows, I...
