Injecting EJB into cxfse service impl...

[yusuf.jakoet]

Hi

I've amended the cxf-wsdl-first-osgi-package example and I'm struggling to get the following to work.  I'm configuring one EJB via spring.  The bundle compiles file.  When I do a features:install, however, I get a dependency error on javax.ejb.EJBHome.  Now, my service implementation was doing a manual ejb lookup and that worked.  All I want to do now is have the ejb injected.

The debug output shows the packages that are wired when the feature is deployed.  Before it fails, the only dependencies that are wired are Spring packages, so it fails due to not being able to find javax.ejb.EJBHome.  Why are those imports not available at the time the spring context is initialised?

Spring configuration:

      <property name="jndiName" value="jndiName" />

      <property name="businessInterface" value="remoteInterface" />

Hi,

I think you need import-package javax.ejb in the pom.xml for your cxf-se bundle.

That's the thing, it's already there.  And if I do a manual lookup in code then it works.  For some reason the spring config doesn't...

[yusuf.jakoet]

A couple of questions:

a) Would it be possible to deploy a spring configuration containing the ejb and then do an osgi lookup via jndi?

b) Can I configure a remote ejb via blueprint configuration? and would i be able to deploy the configuration to smx?

[yusuf.jakoet]

Just tried to deploy a spring config to smx and got the same error:

Caused by: java.lang.ClassNotFoundException: *** Class 'javax.ejb.EJBHome' was not found because bundle org.springframework.context does not import 'javax.ejb' even though bundle wrap_file_____var_java_mtest_jboss_client_jbossall-client.jar does export it. To resolve this issue, add an import for 'javax.ejb' to bundle org.springframework.context . ***

Would I be able to configure the org.springframework.context bundle?

Hi,

Actually org.springframework.context import javax.ejb, but as optional, so after you install your bundle wrap_file_____var_java_mtest_jboss_client_jbossall-client.jar which export javax.ejb, you do osgi:refresh bundle_id_for org.springframework.context, then you could see this package get resolved for org.springframework.context, then you install your cxf-se bundle, you will not see  'javax.ejb.EJBHome' CNFE.

Thanks for that.  It makes sense, but at which point would the osgi:refresh make the spring-context bundle see my packages?  The refresh isn't picking up the packages.

Will re-installing the jbossall-client.jar help?

Thanks

Hi,

jbossall-client.jar export javax.ejb package, right?

After you install jbossall-client.jar successfully(you can check this bundle status, and check if jbossall-client.jar export javax.ejb), then refresh spring-context  should get javax.ejb resolved, it expected the javax.ejb version [2.1.0, 4.0.0), ensure the javax.ejb version exported by  jbossall-client.jar meet the requirement.

Freeman

[yusuf.jakoet]

Yes it does export javax.ejb.

When I refresh the spring-context, i get a few exceptions :

ERROR: JarContent: Unable to read bytes. (java.lang.IllegalStateException: zip file closed)

once it settles, then i can no longer use the 'osgi:' commands in the karaf shell...

here's a snippet of what's happening after i install the jbossall-client.jar...

Hi,

What FUSE ESB version you're using?

If you're using 4.3.0-fuse-00-00, edit etc/config.properties

change

karaf.framework=felix

to

karaf.framework=equinox

Or you should use 4.3.0-fuse-00-01.

I think there's a felix[1] issue related to refresh spring-context bundles

https://issues.apache.org/jira/browse/FELIX-2480

I've switched to equinox.  The bundle installs fine, but cannot start due to the spring dependency.  Same issue, though the spring-context refresh doesn't kill servicemix..

How do i know if the Spring-Context has picked up the packages correctly?

[ffang]

Hi,

You can use

packages:imports bundle_id

to check which package the bundle import

Hi,

Okay, the Spring Context bundle isn't importing javax.ejb.  The command I'm using to install the jbossall-client.jar is

osgi:install -s wrap:file:////path/to/file.jar

Once the bundle is active, and I do a osgi:refresh on the spring context, should it work?  How can I be sure that the Spring Context bundle is the culprit?

Thanks

[yusuf.jakoet]

I've noticed that the packages exported by jbossall-client bundle have the version set to "0.0.0" ie.  (done via packages:export...)

wrap_file_____var_java_mtest_jboss_client_jbossall-client.jar (172): javax.ejb; version="0.0.0"

wrap_file_____var_java_mtest_jboss_client_jbossall-client.jar (172): javax.ejb.spi; version="0.0.0"

Could this be the cause. If so, how do I go about changing that value?

[yusuf.jakoet]

Caused by: java.lang.NoClassDefFoundError: javax/ejb/EJBHome

Is anyone able to get around this issue when injecting an EJB into a cxfse bundle...?
