OW2 Bundles

Florent BENOIT added a comment - 15/Jul/08 3:58 PM Well I think that the main issue is linked to the missing import on log4j

ekkehard gentz added a comment - 15/Jul/08 4:16 PM yes, thats the main issue, but its also problematic if you import the same packages you own in the bundle I have the same problem with the core bundle: imports many many packages, but owns the packages itself in /dependencies/xxx.jar and then exports them also so - if there's anywhere a bundle exporting one of those packages, too, then eclipse PDE detects a cycle and I cannot deploy a bundle with a dependency to easybeans.core - I first have to remove those imports but - as I wrote in the list, I'm working on it to "unbundle" all those jars from core will take some time... I'll report my solution ekke

Florent BENOIT added a comment - 15/Jul/08 4:24 PM I have some problems with transforming each module into a bundle. The main issue is that we've to deploy several jars in order to get something working. For someone that wants only get EasyBeans running on an OSGi gateway, this may be problematic. But for users having existing bundles, this is not great to have some monolitic bundles as classes are not shared. Maybe the best way could be to have some "installation" bundle that may install automatically a set of bundles.So users don't have to bother to install tons of jar in order to get something working and all is modular which is fine. Also, it's a common feature to import what we export. This avoid to get ClassCastException if two bundles are exporting the same packages.

ekkehard gentz added a comment - 15/Jul/08 4:44 PM I had the following scenario: Eclipse 3.4, with PDE target platform this target platform includes: com.springsource.javax.ejb-3.0.0 (I need this for my client bundles using the API) easybeans.core imports , owns and exports the packages from ejb.jar then I developed a bundle with package-import ejb.jar and cannot deploy it from PDE, got a report: cycle com.springsource.javax.ejb-3.0.0; easybeans.core; com.springsource.javax.ejb-3.0.0 after removing the imports from easybeans.core it works well ekke

Florent BENOIT added a comment - 15/Jul/08 5:14 PM Yes, big bundles are great in some cases and very problematic for many other cases So we need to find a way to use "small" bundles (with maven, we already have modules, so one module = one bundle) but to make it easy for end users (and that it is fine also for advanced users)
