Am Donnerstag hat SpringSource das erste Milestone-Release von Spring Data JPA veröffentlicht. Spring Data JPA ist die Weiterentwicklung der Synyx OpenSource Bibliothek Hades.

Hades wurde hauptsächlich von Oliver Gierke entwickelt, welcher bis Anfang 2010 als Software Architekt bei Synyx tätig war. Die Entwicklung des Projekts wurde von Synyx vollumfänglich unterstützt und gefördert, die Bibliothek in vielen Projekten erfolgreich eingesetzt.

Today, I tried to install parts of the SpringSource Tool Suite into Eclipse Helios SR1 via update-site.
After finding the right update-site of the STS for version 3.6 of eclipse (namely: http://dist.springsource.com/release/TOOLS/update/e3.6 and http://dist.springsource.com/release/TOOLS/composite/e3.6) and following the installation instructions carefully, I had Spring IDE 2.5.2 successfully integrated.
But after restarting eclipse I was shocked, it seemed that the update-manager broke down…
when opening the update-manager the log gasped out:
"An internal error occurred during: Contacting Software Sites. java.lang.NullPointerException…"
didn't sound good. After quite a lot of researching and try and failing, I was very glad to find a bug report, which mentioned that this occurs on updating Spring IDE. Thanks to Christian Dupuis from SpringSource, who provided a workaround yesterday. For some reason a second org.apache.commons.httpclient_3.1.0….jar was shipped and confused eclipse. But after commenting one of them out in "configuration/org.eclipse.equinox.simpleconfigurator/bundles.info"
everything was working well again.
Now I can enjoy my Spring IDE and perhaps you can so, too.

Many of the Web-Applications we develop for our customers are based upon our small Framework on top of Spring / Spring MVC. This framework basically brings often used components ready-to-use (or ready to customize) and - of course - makes things even simpler than Spring already does.
