Release 6.5 of Documentum Composer contains bug fixes to allow it to run on Ganymede (Eclipse 3.4). Just to be absolutely clear this isn’t a platform that will be supported by our Tech Support organization because Composer hasn’t actually been certified on it; i.e. it hasn’t been through QA in this configuration. But I checked in the bug fixes and I’ve been developing and running Composer on it for 3 or 4 months now. I haven’t found a problem yet so I am pretty confident that it will work for you.
To upgrade to Ganymede, download and unzip the Eclipse IDE for Java EE from here.
Launch it and use the new (p2) Update Manager to download EMF Validations, which is the only dependency required by Composer not included in the Java EE package. Help ->Software Updates->Available Software->Ganymede->Uncategorized->EMF Validation Framework SDK 1.2.0.
Eclipse will now restart.
Once it restarted close it again. Now copy all folders and jars beginning “com.emc.ide%” from the features and plugins folders of your existing Composer 6.5 install into the dropins folder of your Eclipse for Java EE install. Note that prior to Eclipse 3.4 we used to drop these resources into the the corresponding features and plugins folders. However, Eclipse 3.4 introduced a new provisioning system called p2 and a new configurator. These have deprecated the capability to just drop features and plugins into these corresponding folders. These were deprecated in favour of this new “dropins” folder.
That’s it. You should be all set.
Happy Composing.
