Problems to setup transitive dependency across bundles

[Beta User]

I have maven project with multiple modules that I want to turn into OSGi bundles and deploy to the S2AP to be available to web modules. In order to follow the migration steps carefully, I started with one exported service from one module and created a new project with a simple web module to test it.

Having the Eclipse AP tool to deploy the web module, I received a classpath not found error from the installed bundle. I did not understand why the class loader was not able to find a class that should be available through the spring library, since I included the <Import-Library: org.springframework.spring;version="[2.5.4,3.0)"> header in the manifest file. To get rid of this, I included one Import-Package after every successive complaint from the class loader. So far, my manifest file looks like this:

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-SymbolicName: org.helianto.core
Bundle-Vendor: I-Serv Consultoria Empresarial
Bundle-Name: Helianto Core package
Bundle-Version: 0.0.1.20080612
Import-Bundle: com.springsource.org.apache.commons.dbcp;version="[1.2.2.osgi,1.2.2.osgi]",
com.springsource.org.hsqldb;version="[1.8.0.9,1.8.0.9]"
Import-Library: org.springframework.spring;version="[2.5.4,3.0)",
org.hibernate.ejb
Export-Package: org.helianto.core,
org.helianto.core.creation,
...
Import-Package: org.springframework.context.support,
org.springframework.orm;version="[2.5.5.A,2.5.5.A]",
org.springframework.orm.hibernate3;version="[2.5.5.A,2.5.5.A]",
...
org.springframework.transaction.support;version="[2.5.5.A,2.5.5.A]"

But from the last error report (see below) I see that now the required dependency comes from a spring bundle, not from the bundle I deployed. I certainly missed the point to set up this the right way. I also found a discussion topic having a similar issue: http://www.springsource.com/beta/applicationplatform/comments.php?DiscussionID=216&page=1#Item_0

My question: where in the documentation or discussions can I look for a missing step on my setup?

Thank you,

Mauricio

Hi Mauricio,

Just out of curiosity, are you certain you've properly copied the Hibernate library (e.g., org.hibernate.ejb-library-3.3.2.GA.libd) and all corresponding bundles to the correct locations in the Platform (e.g., repository/libraries/usr and repository/bundles/usr, respectively)?

After doing so, did you restart the Platform as well?

Regards,

Sam

[Beta User]

Thank you Sam,

Well, I missed that. At the time of my previous question, I did not realize the library has only references to bundles actually installed under repository/bundles/usr. But, yes, now I assured -> I properly copied the Hibernate library (e.g., org.hibernate.ejb-library-3.3.2.GA.libd) and all corresponding bundles to the correct locations in the Platform (e.g., repository/libraries/usr and repository/bundles/usr, respectively), and also restarted Eclipse and the Platform (also using Eclipse -clean option). But the error remains:

I also noticed this from the OSGi console:

23 INSTALLED com.springsource.org.hibernate.annotations_3.3.1.g a
24 INSTALLED com.springsource.org.hibernate.ejb_3.3.2.GA
25 ACTIVE com.springsource.org.hibernate.annotations.common_ 3.3.0.ga

Hi Mauricio,

The output from the OSGi console is interesting... What errors, if any, do you get if you attempt to start the Hibernate and Hibernate annotations bundles in the console? E.g.:

> start 22
> start 23

My guess is that some of these bundles' dependencies are missing from the repository. The errors should help us to confirm that's the case.

Thanks,
Andy

Hi Mauricio,

Go to this page...

http://www.springsource.com/repository/app/library/version/detail?name=org.hibernate.ejb&version=3.3.2.GA&sea rchType=librariesByName&searchQuery=hibernate

... and make sure you have each of the bundles listed under the "Required Dependencies" section installed in your repository.

Or, if you're using version 3.3.1 of the Hibernate library, go to this page:

http://www.springsource.com/repository/app/library/version/detail?name=org.hibernate.ejb&version=3.3.1.ga&sea rchType=librariesByName&searchQuery=hibernate

Sam

Hi Sam,

I checked my directory listing against the library listing. It seems to be ok. Here it is:

Hi Mauricio,

Your directory listing only lists the bundles directly referenced by the library, but it does NOT list all of the "Required Dependencies" of those bundles. Please review my previous post.

You'll notice under the "Required Dependencies" section of the SpringSource Enterprise Bundle Repository for the Hibernate JPA library (version 3.3.2) that you need the following as well:

(see the previously listed URL for better formatting)

JBoss Hibernate Object-Relational Mapper com.springsource.org.hibernate 3.2.6.ga

Sam, Andy,

I do not know if you are in Europe or US, what is your time zone? Knowing that would help me plan the rest of my day (I am at GMT-3). Thanks.

Now the error is pointing to other unresolved dependencies. My next step is to place the dependencies in the right place.
