Subject [jira] [Commented] (CMIS-878) Allow loading classes from other OSGi Bundles in OSGi Client Wrapper
Date Tue, 12 May 2015 07:55:00 GMT

Sascha Homeier commented on CMIS-878:
-------------------------------------

Yep, there are some things missing currently:

1) The Bundle Change Listener to react on changes of SPI bundles
     Currently you can stop/uninstall objectfactory/authprovider bundle and it does not affect
the session (classloader is still taken into account)
2) Some research if/how to avoid start level adjustement to ensure spi bundles are loaded
before ClientWrapper

> When using the OpenCMIS OSGi Client Wrapper it is hard to load classes from other bundles.
For example if you specify an own Authentication Provider class as Session Parameter then
the Wrapper will not find this class when it is located inside another bundle. Same problem
should occur when defining an own Cache.
> *1)*
> It would be nice if other bundles could register their Classloaders so that ClassLoaderUtil
can use it when trying to load classes.
> *2)*
> Another simpler option would be to simply add "DynamicImport-Package: *" to the Manifest
of the Wrapper. By doing this the Wrapper will find all classes which are exported by other
bundles. Though this approach feels more like a hack since it breaks modularity.
> What do you think about it?
> Cheers
