Spring IDE into eclipse
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.
