Re: [virgo-dev] Sad tale of JavaAPIforKML...
|
Hi Tim
I hope Dmitry's suggestions have helped, but let me also unpack this further just in case.
It seems that the Virgo Java 6 profile is offering both boot delegation of javax.xml.* packages and a system bundle export of 5 specific javax.xml packages at version 0 (the default). So you have the following options if you want to load javax.xml.transform classes from the framework class loader:
1. Delete the import of javax.xml.transform from your bundle. The classes will be loaded by boot delegation.
2. Delete the version range on the import of javax.xml.transform from your bundle. Your bundle will then be wired to the system bundle for javax.xml.transform, but I *think* class loads will still be boot delegated (which should be harmless) unless you also delete javax.xml.* from the boot delegation property.
3. Keep the version range on the import of javax.xml.transform in your bundle and add an export of javax.xml.transform at e.g. version 1.3.3 to the system packages property. Your bundle will then be wired to the system bundle for javax.xml.transform, but I *think* class loads will still be boot delegated (which should be harmless) unless you also delete javax.xml.* from the boot delegation property.
Also please note that if you use bundlor to calculate the manifest of your bundle, it can take the OSGi profile into account in its calculations and avoid generating imports for boot delegated packages (although I'm not absolutely certain what it does when there is an overlap between boot delegated packages and system packages as is the case here, but *if* there's a bug we can fix it). See [1].

Glyn

Tim,
There is some more to this :) I missed it initially.
There is this:
org.osgi.framework.bootdelegation = \
org.eclipse.virgo.osgi.extensions.*,\
org.eclipse.virgo.osgi.launcher.*,\
org.eclipse.virgo.kernel.authentication,\
com.sun.*,\
javax.xml.*,\
org.apache.xerces.jaxp.*,\
org.w3c.*,\
org.xml.*,\
sun.*
So any javax.xml.* packages will be delegated for resolution to vm boot classloader.
I think this is a best explanation of bootdelegation and system.packages that I have seen so far: http://blog.springsource.com/2009/01/19/exposing-the-boot-classpath-in-osgi/
Maybe in your environment it makes sense to customize those values and see if Virgo still comes up.
For example you might try to take out javax.xml.* from list of org.osgi.framework.bootdelegation packages and just rely on org.osgi.framework.system.packages. I can't compute the impact that it might have. But I think you have choices here.
You can try dropping all of the xml libraries that you need into $VIRGO_HOME/lib and those jars will be on the server classpath (look in bin/setupClasspath.sh/bat) and will be available for resolution with bootdelegation. No changes needed to the java6-server.profile.

Dmitry

Tim,
Following packages are exported by means of org.osgi.framework.system.packages (look in lib/java6-server.profile). Remove version range or set it to version="0" and you should be in business.
javax.xml.transform,\
javax.xml.transform.dom,\
javax.xml.transform.sax,\
javax.xml.transform.stax,\
javax.xml.transform.stream,

We are trying to bundlize JavaAPIforKML so that it is deployable on Virgo.
Despite all our efforts, we are getting the following when we deploy to Virgo. The issue seems to be that JAK relies on JAXB. We changed the pom to reference the Spring bundles and added the Spring maven repos to the project, and added the dep jar download so we could see all the required jars. The result is that we have spent quite a bit of time on this issue and the bundle won't deploy. The only conclusion is that the bundles we have in the user repo claim to export javax.xml.transform but something has gone wrong. In days past, we have just punted and put the jars in the bundle, but we are trying to do this as cleanly as possible.

Anyone have suggestions about how to proceed? This is a killer issue for our project and even though this is not likely a Virgo issue, Virgo is going to take the blame.
