"Unresolved constraint in bundle" deploy exception

[rkozura]

Hello, I am just starting out using FUSE ESB and I am having problems deploying my osgi bundle.

I start out building the cxf-osgi example program using maven.  I added a mandatory external jar to the maven repository with the following command:

mvn install:install-file -Dfile="technica -util.jar" -DgroupId=com.technicacorp -DartifactId=util -Dversion=1.0 -Dpackaging=jar -DgeneratePom=true

I edited the project's pom.xml file to include the dependency and import the package.  I do a "mvn install" and it generates a .jar file.  I drop the jar file into the deploy folder while FUSE ESB is running and I get the following error:

karaf@root> ERROR: Error starting file:  test.jar (org.osgi.framework.BundleException: Unresolved constraint in bundle test : package; (package=com.technicacorp.util.distributor)) org.osgi.framework.BundleException: Unresolved constraint in bundle test : package; (package=com.technicacorp.util.distributor)

        at org.apache.felix.framework.Felix.resolveBundle(Felix.java:3299)

        at org.apache.felix.framework.Felix.startBundle(Felix.java:1657)

        at org.apache.felix.framework.Felix.setActiveStartLevel(Felix.java:1128)

        at org.apache.felix.framework.StartLevelImpl.run(StartLevelImpl.java:264

)

        at java.lang.Thread.run(Thread.java:595)

How the heck do I solve this problem?  I am sorry if I am leaving details out, nothing comes to mind right now.  If you need more information I would be glad to supply it.  I have attached my pom file if you want to have a look.

Thank you for helping me.

Hi,

This error means you are missing a bundle which export com.technicacorp.util.distributor package.

Thank you for your suggestion.  So I should add an export package header to the external jar's manifest file?

I tried to "osgi" an external jar using a tool called bnd.  It worked and added export package headers, but when I rebuilt and deployed, I still got the same run time error

I cleaned up the MANIFEST file a little bit for readability:

Manifest-Version: 1.0

Created-By: 1.5.0_22 (Sun Microsystems Inc.)

Bnd-LastModified: 1280811698546

Export-Package: com.technicacorp.util.distributor

Bundle-Version: 0

Bundle-Name: technica-util

Originally-Created-By: 1.5.0_17-b04 (Sun Microsystems Inc.)

Bundle-ManifestVersion: 2

Bundle-SymbolicName: com.technicacorp.util

Tool: Bnd-0.0.384

I feel like I am missing something important.  Any help is greatly appreciated.

Thank you.

Hi,

You need install technica -util.jar as a bundle which export com.technicacorp.util.distributor package.

You can read about deploying and using OSGi here

http://fusesource.com/products/enterprise-servicemix4/#documentation

There is a OSGi guide from that link.

I resolved my issue by issuing the command "osgi:install technica-util.jar" within felix.  I then started the bundle with the command "osgi:start 'number of the bundle to start'" and I no longer get my run-time error.

Thank you for your help.

I am sorry to bump this thread, but is there any other way I could have solved this?  After trying to develop other web services, I keep getting back to the unresolved constraint issue and it seems sloppy to keep manually adding jar files.

I exported the correct class "com.technicacorp.util.distributor" in the manifest of the jar (that is in the Maven repository), and I imported the package and have the jar as a dependency in the pom.

Anyone have any hints?  I would greatly appreciate it.

You need to install the third party jar in the karaf,

Use this command if it works for you,

osgi:install -s wrap:file:///C:/Bridge/wlfullclient.jar

Then include the package name in the Import-Package

[rkozura]

Thank you divakar, but this is the way I am doing it now.  Is there any possible way to not manually install the jar into osgi?

For instance, can't I just put the jar inside of the local repository and configure the pom to install the jar automatically?

I know I am knit picking, but I am trying to be consistent.

[divakar]

I came across a help saying that, you can install the jar in the local maven repository and include the dependencies in the pom.xml.

BTW I am not an expert in here, I am also try to get some help!

Cheers,

Hi,

You can put all necessary bundles in features file to do provisioning.

Basically a feature is a set of bundles which can do certain functionality.

Take a look at to get more details.
