Unresolved constraint in bundle, missing requireme

Question

I am having a project using OSGi-(felix), SpringDM, hibernate, maven. when I installed bundle, it is ok, the output when I run bundle id is:

LastModified         1384619994484

Bundle                 169|Installed  |    1|DrugManagerDAO (1.0.0)

This is what I see, when I start this bundle:

In addition, there is an completed error of bundle in felix.

Answer 1

Do you have this bundle installed in your container (Felix) as well?

     <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate</artifactId>
        <version>3.2.6.ga</version>
    </dependency>

If not install it and then see what happens when you start your bundle.

Answer 2

For missing requirement [Bundle-number] osgi.wiring.package, I added it as export-package in pom.xml, as mentioned below:

<Export-Package>
package for which error is thrown
</Export-Package>

and it worked. So if it throws the above error even after declaring it as dependency, export-package may help
