Hello virgo users

I'm facing a "Uses violation" error that I do not understand and hope that someone can give some tipps how to get things up and running.

We created a "super-bundle" of the neo4j database that contains all internal dependencies as jar files and exports org.neo4j.* and some other packages. A second bundle (org.springframework.data.neo4j) uses this "super-bundle", but cannot be resolved due to these uses violations:

Caused by: org.eclipse.virgo.kernel.osgi.framework.UnableToSatisfyBundleDependenciesException: Unable to satisfy dependencies of bundle 'org.springframework.data.neo4j' at version '2.0.0.BUILD-SNAPSHOT': Cannot resolve: org.springframework.data.neo4j
    Resolver report:

             Resolver reported uses conflict for import


I cannot understand why these violations show up. I walked through the imports of both bundles, but could not find any conflicts.

Our client bundle imports the neo4j super-bundle with Import-Bundle. When I deploy this one, I get the following message that I cannot understand neither:
Detected Import-Bundle of bundle 'org.neo4j.neo4j-osgi-bundle' version '0.1.0.SNAPSHOT' which exports packages that are exported by the system bundle: consider importing the packages explicitly. For example, use Import-Package: org.neo4j.cypher.javacompat,scala.annotation.unchecked,org.apache.lucene.util,many many more...

Why does virgo think that this bundle exports the same packages as the system bundle?

I'd really appreciate any hints how to solve this.

The two bundles I was talking about can be found in the pickup directory of the following zip file. It also contains the repository/usr directory with all dependencies:
http://dl.dropbox.com/u/11739559/neo4j-bundle.zip

We are using Virgo 3.0.1.


Best regards,
James

Thanks James. I'm grabbing the zip and will take a look when I have a spare few minutes. (I'm "rippling" some changes up at the moment, so I can't launch Virgo without spoiling my day.)

I may have found a clue to the first problem by eye-balling the manifests. The Neo4j bundle exports org.neo4j.kernel.impl.transaction with a uses constraint on javax.transaction and javax.transaction.xa, but Neo4j does not appear to import (or export) these packages. This is a toxic combination as any bundle, such as the Spring Data Neo4j bundle, that imports org.neo4j.kernel.impl.transaction and javax.transaction/javax.transaction.xa will hit a uses constraint violation because it can't possibly wire to the same version of the javax.transaction/javax.transaction.xa packages as the Neo4j bundle. So it looks like the Neo4j bundle manifest is faulty and needs correcting.

(I am guessing the second problem is related although I haven't gone into that yet and the diagnostics are misleading, which looks like a bug in Virgo on the face of it.)

...
Started bundle 'org.springframework.data.neo4j' version '2.0.0.BUILD-SNAPSHOT'.
...

... Shocked

Ahhh. javax.transaction was indeed the bad guy. The jar "geronimo-jta_1.1_spec-1.1.1.jar" that has been included in the neo4j bundle *is* an implementation of javax.transaction. I have not noticed that. Sad
After excluding this dependency so that it is not included in the jar anymore, I can successfully start all bundles - including our client bundle. And the message that the neo4j bundle is exporting packages that also the system bundle does also disappeared - although this message should not have been shown since the neo4j bundle actually did not export the packages. But this seems to be a minor issue for me now.

Thank you very much for pointing me to the right direction. I could have "eye-balling the manifests" for another couple of hours without noticing this inconsistency. You could sometimes lend me an eye ball... or two... Smile


Best regards,
James

Hi James

Glad you are sorted. I'm following up to see if the original diagnostics can be improved. Running on a development build of Virgo Tomcat Server I seem to be missing at least one package:

Cannot resolve: org.springframework.data.neo4j
Resolver report:
An Import-Package could not be resolved. Resolver error data <Import-Package: org.springframework.data.annotation; version="[1.0.0,2.0.0)">. Caused by missing constraint in bundle <org.springframework.data.neo4j_2.0.0.BUILD-SNAPSHOT>
constraint: <Import-Package: org.springframework.data.annotation; version="[1.0.0,2.0.0)">
An Import-Package could not be resolved. Resolver error data <Import-Package: org.springframework.aop.framework; version="[3.0.6,4.0.0)">. Caused by missing constraint in bundle <org.springframework.data.commons_1.2.0.BUILD-SNAPSHOT>
constraint: <Import-Package: org.springframework.aop.framework; version="[3.0.6,4.0.0)">

Did you also upgrade Spring to 3.0.6?

Regards,
Glyn

Oh yes. We had to upgrade to Spring 3.0.6 by putting the spring libs into the repository/ext folder. Shell I make you the ext folder available?

(Sorry for the delay in responding - somehow I got unsubscribed from this thread).

Nah, that's ok, but thanks for confirming. I can grab Spring 3.0.6 no problem.

Raised https://bugs.eclipse.org/bugs/show_bug.cgi?id=366218 to cover the basic insufficiency of the resolution diagnostics in this case.
