OSGi ClassNotFoundException despite using DynamicImport-Packages =
*
Hi,
I am using ehcache 2.5.1 to cache my objects. I've deployed on ServiceMix
4.3.
I am using the ServiceMix bundle version of Ehcache, which has the headers
set as follows
karaf@root> osgi:headers 281 | more
Apache ServiceMix :: Bundles :: ehcache (281)
---------------------------------------------
Manifest-Version = 1.0
Bnd-LastModified = 1333038240996
Tool = Bnd-1.50.0
Built-By = jbonofre
Build-Jdk = 1.6.0_26
DynamicImport-Packages = *
Created-By = Apache Maven Bundle Plugin
Bundle-Vendor = The Apache Software Foundation
Bundle-Name = Apache ServiceMix :: Bundles :: ehcache
Bundle-DocURL = http://www.apache.org/
Bundle-Description = This OSGi bundle wraps ehcache 2.5.1 jar file.
Bundle-SymbolicName = org.apache.servicemix.bundles.ehcache
Bundle-Version = 2.5.1.1
Bundle-License = http://www.apache.org/licenses/LICENSE-2.0.txt
Bundle-ManifestVersion = 2
Import-Package =
javax.jms;resolution:=optional,
javax.management,
javax.management.openmbean,
javax.naming,
...
I have made sure that my bundle exports the offending package:
karaf@root> packages:exports 282
ID Packages
282 a.b; version=1.0.0.SNAPSHOT
282 a.b.c; version=1.0.0.SNAPSHOT
And yet I still get the runtime error:
Caused by: java.lang.ClassNotFoundException: a.b.SomeClass not found by
org.apache.servicemix.bundles.ehcache [281]
at
org.apache.felix.framework.ModuleImpl.findClassOrResourceByDelegation(ModuleImpl.java:812)

What am I missing?
cheers,
Kato

Hi James,
At the moment I can not answer precisely,
But to address the problem IHMO it is better to remove the dynaminc import
In this manner you can figure out What you're missing.
Could probably be the bundle ehcache but it is merely a hypothesis.
let me know

Hi Filippo,
The package is one of my own that I have deployed in a bundle. In the above
post I have called it a.b
Specifically, the exception reports a class within the package cannot be
found, i.e. the class I am trying to cache.
Could there be some version problem? I am pretty sure that there are no
other packages also exporting the same package since there is only one
version reported through packages:exports
Cheers,
James

Thanks folks. I can see there is nothing left to be done on this one. I'll
check out those links for future.
What are the approximate timescales for release of these patched bundles?
Cheers,
Kato

Hey Filippo,
Good catch - if you refresh that page now, this should be fixed as well!

Kato,
You can also find more information about contributing and creating patches
in http://servicemix.apache.org/community/contributing.html - Filippo
already pointed you to the right location for JIRA, so disregard the broken
links in that page (will fix that up right after sending this mail ;))

Hi James,
I have just made a jira to trace the problem.

I hope this is ok for you.

Thanks Gert, you have sharp eyes! Just what I was looking for...
I have manually adjusted the header and it seems to work.
I am not sure how to patch or raise a JIRA. Can you give me the links to the
necessary information please?
Cheers,
James

Kato,
There seems to be a problem with the OSGi headers of that bundle. The
bundle header should be called DynamicImport-Package instead of
DynamicImport-Packages. Could you raise a JIRA issue to get that fixed?
If you fancy providing a patch as well, that would be very welcome too
obviously ;) Source code can be found at
http://svn.apache.org/repos/asf/servicemix/smx4/bundles/trunk/ehcache-2.5.1/

Gert

Hi James,
another approach to follow see if the packages used in class a.b.SomeClass
are exported by ehcache bundle
