Felix Meschberger commented on SLING-2109:
------------------------------------------
Added system bundle extension fragments for XML and Transaction APIs in Rev.
1138907.
Added these bundles to the build project in Rev. 1138908
Added these bundles to the launchpad builder in Rev. 1138909
Removed the XML and Transaction APIs from the jre-1.?.properties and activation
package from the jre-1.6.properties in Rev. 1138910
All integration tests still pass.
> Separate some system bundle provide packages into properties for easier

> Key: SLING-2109
> URL: https://issues.apache.org/jira/browse/SLING-2109
> Project: Sling
> Issue Type: Improvement
> Components: Extensions, Launchpad
> Affects Versions: Launchpad Base 2.3.0
> Reporter: Felix Meschberger
> Assignee: Felix Meschberger
> Fix For: Launchpad Base 2.3.2
>
>
> Currently a number of Java Extension packages are exported without a version
> from the system bundle; for example javax.transaction.*, or javax.xml,*.
> The problem with these packages is that some applications will not want to
> depend on these packages from the environment hence do not want them to be
> exported from the system bundle. Yet, in different contexts like the default
> Sling Launchpad build, we just want them available.
> To fix this issue, the following should be done:
> * Remove Activation, Transaction, and XML APIs from the System Bundle Export
> * Create two system extension fragment bundles: (1) for JTA and (2) for XML
> APIs
> The javax.activation API is problematic anyway and should probably not be
> used from the environment due to the extension loading mechanism employed by
> default. The JTA and XML API system extension fragment bundles can be
> replaced by real bundles. For example to use JAT inside the OSGi framework
> the Apache Aries Transaction Manager bundle can be deployed instead of the
> JTA system extension fragment.
> This is related to SLING-1958 which is about replacing the XML related
> exports from the system with bundles embedding the API in the framework
> itself and thus encapsulating from the environment.
