Could someone help me and explain why "org/w3c/dom/NodeList" is not found ?
NodeList is a standard java inteface included into the jdk I use (1.5).

Please sure that a bundle which export the org.w3c.dom package in your

Re: exception using groovy bundle
Posted by Felix Meschberger <fm...@gmail.com>.
Hi,
Assuming the framework actually exports the org.w3c.dom (and other)
packages as stipulated by David in his separate message, this should
actually work. Have you verified the org.osgi.framework.system.packages
property containing the required packages. This should be set correctly
if you use the Felix main launcher. If you launch the Felix framework
you should ensure this manually.
Maybe you could try to use the Maven Bundle Plugin to generate the
required imports for your groovy service bundle ?
Regards
Felix

I think Stuart has the right idea, make sure you actually wrap all
calls to Groovy with the setting the context classloader code.
Furthermore, you will need to have your bundle importing the
org.w3c.dom packages.
If that doesn't work you could try to enable bootdelegation for the
missing packages but that would be the last resort. Additionally, you
might want to post your code/manifest/bundle-layout someplace so that
we can have a look at it.

Karl

Re: exception using groovy bundle
Posted by "fred.ac" <fr...@scarlet.be>.
Here are the modif made on my original test code :
start method in Activator.java
...
ClassLoader old = Thread.currentThread().getContextClassLoader();
try {
Thread.currentThread
().setContextClassLoader(getClass().getClassLoader());
groovyService = new GroovyService(); <===== this line of code
cause the exception NoClassDefFoundError: org/w3c/dom/NodeList
context.registerService(GroovyService.class.getName(),
groovyService, null);
} finally {
Thread.currentThread().setContextClassLoader(old);
}
...
I also modified the manifest with :
Import-Package: org.w3c.dom,org.osgi.framework

interesting - I think Equinox sets the thread-context-classloader (TCCL)
in bundles to be a special classloader, called the ContextFinder, which
tries to fix various legacy issues - it works like the TCCL solution that
Felix mentioned, but also does a lot more checking of what's visible on
the stack (FYI, the ContextFinder can be used on other frameworks)
however, this does mean that just because a bundle works on Equinox,
it doesn't mean that the bundle will work on a "strict" OSGi framework
(note that although Equinox is the reference implementation for OSGi,
it doesn't run in reference mode by default because it has to support
legacy code in Eclipse)
btw, where did you put the TCCL switch?
around the service registration or wrapped around the Groovy service?

Re: exception using groovy bundle
Posted by "fred.ac" <fr...@scarlet.be>.
Thanks, I don't know how Groovy is using class loaders but I tried the code
you suggested wthout any success :-( same exception, grrrr...
I just tried to run my test with equinox and it works. (I just executed pax
runner with an extra option '--p=e' to run equinox that guarantee that my
code/config is exactly the same)
I prefer to use felix container but I need you help, yet an other idea ?
Fred.

Re: exception using groovy bundle
Posted by Felix Meschberger <fm...@gmail.com>.
Hi,
How is Groovy using class loaders ? Is it using the Thread context class
loader ? In this case, you would have to set the correct context class
loader on the current thread before calling into groovy. Something like
this in the activator start() method:
...
ClassLoader old =
Thread.currentThread().getContextClassLoader();
try {
Thread.currentThread().setContextClassLoader(getClass().getClassLoader());
... do groovy stuff ...
} finally {
Thread.currentThread().setContextClassLoader(old);
}
Regards
Felix

Re: exception using groovy bundle
Posted by "fred.ac" <fr...@scarlet.be>.
I also tried to add the package in the import manifest section :
Import-Package: org.w3c.dom,org.osgi.framework
but I doesn't change anything, I still receive :
java.lang.NoClassDefFoundError: org/w3c/dom/NodeList
Any other ideas ?
Thanks
Fred.

Re: exception using groovy bundle

Hi Fred,
Looking at the bundle manifest, it seems that the org.w3c.dom package is
not imported by your bundle. Could this be the cause ?

Felix
