bundle-classpath problem
Hello,
I think I hav a problem with the Bundle-Classpath. I want to import some
jars inside the bundle-jarfile, so I used the Expression
Bundle-Classpath: xy.jar. But by starting my app I get a
FileNotFoundException, cause the Class (khs2010com.echoosgi.Main.class)
implementing the BundleActivator doesn't get found. I think it's because
of the classpath althoug the Main.class is inside the directory
"khs2010com/echoosgi". The OSGi-R4 says that the classpath would be the
bundles root directory, so I don't understand why the class doesn't get
found. If I cancel the Bundle-Classpath expression it works, but missing
the needed jars of cause.
Manifest-Version: 1.0
Bundle-SymbolicName: MA
Bundle-Description: A bundle that displays messages at startup and whe
n service events occur
Bundle-Name: Service listener example
Created-By: 1.5.0 (Sun Microsystems Inc.)
Bundle-Activator: khs2010com.echoosgi.main.MainActivator
Bundle-Vendor: Apache Felix
Bundle-Version: 1.0.0
Bundle-Classpath: Echo2_App.jar, Echo2_Extras_App.jar,
Echo2_Extras_WebContainer.jar, Echo2_WebRender.jar, Echo2_WebContainer.jar
Import-Package: khs2010com.osgiifaces, org.osgi.framework,
nextapp.echo2.app
Export-Package: khs2010com.osgiifaces, nextapp.echo2.app
I hope someone can help me with this simple problem.
Thanks
Achim

Well, if you are starting it via embedded execution, then you would
definitely need to include "javax.naming" in the
org.osgi.framework.system.packages property in the config map you give
to Felix' constructor, because this property is only set if you are
using the standard launcher.

I'm using JDK 1.5 and start felix with embedded execution. But the problem with importing javax.naming has been solved without doing something. :-D
But thanks for the quick responses, that helps a lot.

Standard Java packages are not automatically available according to the
spec, but Felix is configured to automatically export them for convenience.
Looking in the conf/config.properties file, it appears that javax.naming
is available in there, so it looks like it should be exported for resolving.

could you tell us what version of JDK and Felix you are using, and how are
you starting Felix?
also is there an import clause for javax.naming in your manifest?
finally, if you could provide the exception trace showing the resolve error,
that would be great

I thought the standard java-packages are automatical avaible for the
bundles. But javax.naming can't be resolved.

Thanks for the short description. Now it works fine.

the default Bundle-Classpath entry if not set in the manifest is . (ie. dot)
looking at the manifest, you're setting it to:
Bundle-Classpath: Echo2_App.jar, Echo2_Extras_App.jar, \
Echo2_Extras_WebContainer.jar, Echo2_WebRender.jar, \
Echo2_WebContainer.jar
without a dot, which means only classes inside the listed jars will be
available
if you have classes (non-jarred) inside your bundle then you need to add a
dot entry:
Bundle-Classpath: ., Echo2_App.jar, Echo2_Extras_App.jar, \
Echo2_Extras_WebContainer.jar, Echo2_WebRender.jar, \
Echo2_WebContainer.jar
BTW, if you have classes (non-jarred) whose packages are inside a sub-folder
(such as org.foo.MyClass located at <bundle>/somedir/org/foo/MyClass)
Bundle-Classpath: ., somedir, Echo2_App.jar, Echo2_Extras_App.jar, \
Echo2_Extras_WebContainer.jar, Echo2_WebRender.jar, \
Echo2_WebContainer.jar
just like how a normal java classpath works (except it uses commas)
