We have an OSGi project which needs spring and hibernate capability. I tried adding them separately as bundles, but they are not visible to the runtime environment. Below is a screenshot of our project (better picture http://i.stack.imgur.com/d6gV9.png). In the picture the plugins start with spring and hibernate contain the jars and I added them to the import packages in the needed bundles. I'm also attaching a sample manifest with this. Any help is appreciated. I always get classnotfoundexceptions for spring classes.
I created the jar bundles using eclipse's create plugin fro archives. In the wizard I selected them to be standard OSGi plugins (not sure if that is the right way). I'm building the project through IBM RAD (Aries).

The answer is in the error message: ClassNotFoundException: org.springframework.web.context.request.RequestContextListener.
Package org.springframework.web.context.request is not listed in the imports of your bundle.

I want to use cglib in an RCP client. The RCP client is build using maven and the tycho plugin. We are useing a manifest first strategy.
This is my MANIFEST.MF:
Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: INFO+ RCP Common UI Plug-in
Bundle-SymbolicName: a.company.prj.rcp.common.ui
Bundle-Version: 8.0.14.qualifier
Bundle-Vendor: Schweizerische Bundesbahnen SBB
Bundle-RequiredExecutionEnvironment: JavaSE-1.7
Bundle-Activator: a.company.prj.rcp.common.ui.CommonUIPlugin
Bundle-ActivationPolicy: lazy
Export-Package:
a.company.prj.rcp.common.ui,
...
a.company.prj.rcp.common.ui.wizards.page
Import-Package:
org.apache.log4j;version="1.2.17"
Require-Bundle:
org.eclipse.ui;bundle-version="3.7.0",
org.eclipse.ui.forms;bundle-version="3.5.101",
com.ibm.ws.jpa.thinclient;bundle-version="8.0.6",
...
a.company.prj.rcp.core;bundle-version="8.0.14",
...
To add cglib I changed the Import-Package section to:
Import-Package:
net.sf.cglib;version="3.2.0",
org.apache.log4j;version="1.2.17"
Now Eclipse complains with:
No available bundle exports package 'net.sf.cglib'
Ayn ideas how to include cglib with this environment?
You will need to add the cglib bundle to your target platform, i.e., the set of all bundles Tycho will consider when resolving dependencies. You have three options to do so (taken from the Tycho wiki page on this topic):
You can simply add an entire p2 repository to your target platform.
You can use a .target file and reference the cglib bundle therein (as already suggested by stempler).
You can declare a Maven <dependency> on cglib and make Tycho “consider” it.
As you already have a working Tycho build, I suggest you use whatever option you or your colleagues have used in the build before.
One more note: Options 1 and 2 require that the cglib bundle is available in a p2 repository, whereas option 3 works even if the bundle comes from a “normal” Maven repository like the Central Repository. But in all three cases the cglib JAR must be a valid OSGi bundle, i.e., include an OSGi MANIFEST.MF with Bundle-SymbolicName etc.
You should build the cglib jar file to a plugin and install it in Eclipse before you can use it. You can refer to this link: How can I add the external jar to the eclipse rcp application?
I have a large Java application that's mostly networking and file processing with lots of DB access. There's no UI. We expose a few web services (embedded Netty) and call some external rest web services. The project is built with Ant. It's about 10 different jars plus maybe 30-40 libraries.
My current task is to move the project to the OSGi framework. I am startling slowly.
Following the examples in "OSGi In Action" chapter 6, I have used the BND ant task to put the entire project into one huge jar file. This worked. I am able to run the program using java -jar. Here's my current .bnd file:
-output: bundle/MerchantServicesBundle.jar
-include: manifest/merchantservices.manifest
Bundle-Name: MerchantServices
Bundle-SymbolicName: com.shopping.services.merchant
Bundle-Version: 4.1
Main-Class: com.shopping.merchant.services.netty.MerchantServices
Class-Path: /home/ppantera/repositories/MerchantJava/modules/MerchantServices/conf/
Private-Package: *
I am using Apache Felix 4.0.3. From the Gogo shell I can install the bundle but when I start it I get this:
org.osgi.framework.BundleException: Unresolved constraint in bundle com.shopping.services.merchant [8]: Unable to resolve 8.0: missing requirement [8.0] osgi.wiring.package; (osgi.wiring.package=android.dalvik)
Why does Felix think this is an Android project?
There doesn't seem to be much about this on the 'net. Would you recommend using an older version of Felix so I'm sheltered from the newer OSGi features that could cause me confusion?
I tried adding this to my .bnd file:
Require-Capability: osgi.ee; filter:="(&(osgi.ee=JavaSE)(version>=1.7))"
That didn't help. What am I doing wrong? Any other pointers?
It looks like somehow bnd detected a requirement to an Android package, and added that to the MANIFEST.MF, it could be in your code, but could also be in one of your 3rd party libraries.
Check your manifest to be sure, I guess you'll find something like
Import-Package:android.dalvik.
If that's the case you can test the bundle by manually removing that header and see if that helps. When you've got that clear, you can resolve it for example by making that import optional in bnd.
One of easy solution is:
Go to FuseESB console:
Type the command:
osgi:install mvn:commons-io/commons-io/2.1
Replace 'common's-io' with your your dependency's group id and artifact id (Maven)
e.g my dependency was:
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>2.1</version>
<scope>provided</scope>
</dependency>

I got the security issue with a big Eclipse plugin Maven project, which uses Xtext, Xtend and fornax-oaw-m2-plugin (which fails).
I extracted the used classpath, and searched in there if the incriminated class is present in at least two jars, but no. It is only present in one bundle. Could I grab more information into the stacktrace? I could provide many more information.. I google since two days and not found interesting clue so far. As the class in in an Eclipse bundle, i can't change it safely..

Bundle-RequiredExecutionEnvironment: JavaSE-1.6
I have an OSGi bundle and I'm using java mail api in it to add mail functionality.
The problem I'm facing is, the bundle class loader is not adding the entries for mail-1.4.jar and activation.jar in classpath variable which it creates while loading the local or global classes.
I've added the mail-1.4.jar and activation.jar in the bundle classpath in manifest and these jar are simple jars(not the OSGi bundles). And these are in lib directory in my bundle.
Now while loading javax.mail.Address class ClassNotFoundException is thrown.
And this is when I'm running my application using command line.
It works completely fine when I run it in Eclipse.
I'm using equinox as my container.
Any suggestions?

Your use of the bundle classpath is unusual. You should use Import-Package (best practice) or Require-Bundle for dependencies. Bundle classpath is saying all those jars are packaged inside a lib folder inside your bundle archive. I suspect this isn't the case, and even if it was, you'd be totally bypassing all the modularity Eclipse gives you.
Try adding the 'javax.mail' package to your Import-Package header. For an explanation of why this isn't needed in Eclipse, see i/Why_does_Eclipse_find_javax.swing_but_not_Felix%3F.
Make sure you have included your lib folder inside the bin.includes (Build Tab in the Manifest editor) or they won't get exported in the final jar.
This is a very annoying 'bug' that it works in eclipse (because the files are accessible in the file system) but the builder will ignore not included files.
I have a Vaadin application, which I'm trying to build as a set of OSGI bundles using Maven + BND.
I can't deploy the bundles To Apache Felix because some dependencies can't be resolved.
Apache Felix complains that can't find package XYZ required by bundle "A", although this package is defined in this same bundle!!
I looked at the MANIFEST.MF file generated by Maven + BND and saw that the package (XYZ) from this bundle is added to both "import" and "export" sections. I understand why "export", but why "import"?? Why is the bundle trying to import its own package?

This is correct behaviour. The explanation is in section 3.5.6 of the OSGi core specification.
Regarding the unresolved error from Felix... this must be related to something else. Please post the actual error message.
Niel is, of course correct. To be honest though, I've been very successful with using the noimports:=true to get around this. In my applications, I usually have the following in my maven-bundle-plugin section:
<Export-package>*;noimports:=true</export-package>
This results in all of your packages being exported into OSGi, and none of them will appear in your import-package section. If you only need a couple of your exported packages to not appear in your import-package section, you can set the noimports flag for each individual package. Lastly, this syntax is from BND, so it should also work in your .bnd files.
