How to import class (bean) from an other bundle

[walter.accantelli]

Hi all,

I have 2 osgi bundle (osgi-import-sample1 and osgi-export-sample1) and this is what I would like to do:

1) export a class (called BeanToExport) from bundle osgi-export-sample1

2) import/use that class (BeanToExport) in bundle osgi-import-sample1

This is what I've done:

1) In osgi-export-sample1, I've created a simple Bean (com.bundleexport.beans.BeanToExport) that implements InitializingBean and DisposableBean and it's exported with the following configuration in pom.xml:

          <Export-Package>

               com.bundleexport.beans.BeanToExport

          com.bundleexport</groupId>

               <artifactId>osgi-export-sample1</artifactId>

               <version>0.1</version>

               <type>bundle</type>

               <scope>compile</scope>

          </dependency>

          ....

          <Import-Package>

               *,

               ...,

               com.bundleexport.beans

          </Import-Package>

After that, when I try to use the BeanToExport inside osgi-import-sample1, that class is not visible - I cannot import/use that class in osgi-import-sample1.

Is there something I miss or I done wrong?

I've attach the source code, hope this help to undestand.

Hi,

One obvious problem I can tell is

you should use

<Export-Package>

com.bundleexport.beans

</Export-Package>

but not

<Export-Package>

com.bundleexport.beans.BeanToExport

</Export-Package>

Could you change it and do a quick test again?

Hi Freeman,

I try, but nothing has changed; error still remain....

I solved.

1) In bundle export, I removed Export-Package tags from maven-bundle-plugin configuration (by default, all packages that are not defined in Provate-Package tags are exported)

2) In bundle import, there is no need to specify import packages, they are automatically available from all other bundles.

After these changes, I re-build both bundles and it works: I can use exported packages from bundle1 (osgi-export-sample1) into bundle2 (osgi-import-sample1).

Note: I notice that sometimes, in eclipse, it is necessary to "Update Project Configuration" to make changes works (see screenshot).

I attach the updated bundles, hope this can help someone.
