Missing requirement package in OSGI Bundle - Felix & Servicemix

Question

I have spent a few days trying to understand how to deploy as OSGI bundle and need some help. I am using servicemix 4.5.2, maven 3.1.0 and maven-bundle-plugin 2.4.0. I have added the following tags in my .pom

<Embed-Dependency>*;scope=compile|runtime</Embed-Dependency>    
<Embed-Transitive>true</Embed-Transitive>

My bundle builds and when I deploy into servicemix, I get a series of BundleExceptions. I iteratively add the missing packages to my pom until I hit a wall. "Missing requirement package; (package=com.ibm.ejs.ras)". The immediate issue is that I can't find the ras.jar to download or in a Maven repository. But I think the larger issue is that I am doing something incorrectly that is resulting in my having to manually track down transitive dependencies.

I have dug around and saw that common issues were resolved by using the pre-bundled versions from Spring and Fuse. The Fuse repository appears to have vanished and the Spring one seems to be sun-setting and doesn't have all the .jars I need. I also tried the bundleall maven-bundle-plugin which I saw on another post the goal is now deprecated). That resulted in "Error generating OSGi bundle for project org.beanshell:bsh-core: aQute.bnd.osgi.Descriptors$PackageRef cannot be cast to java.lang.String".

I have used previous (pre-OSGI) versions of servicemix and camel and have high regard for both products. However, I am losing steam (and work time) trying to get over the OSGI hurdle and Mule is becoming more attractive. If anyone has some insights, they would be greatly appreciated.

Thank-you.

Answer 1

com.ibm.ejs.ras is probably an optional dependency to one of the JARS you have bundled in.

You would update your Import-Package to filter out the offending package.

<Import-Package>!com.ibm.ejs.ras, *</Import-Package>.

Also:

Embed-Dependency uses Bundle-Classpath under the hood. I'd defer to the creator of the tool that is enabling you to do this: http://www.aqute.biz/Bnd/FAQ#bundleclasspath

I would definitely agree that Embed-Dependency is definitely not necessary in this case, considering you are using ServiceMix which comes with 90% of what you are needing in this case anyway. The rest can be installed within ServiceMix itself using mvn: or wrap:mvn: style-urls. (which is only dbcp and lang3 and selenium)
