[jira] Created: (CAMEL-577) ResolverUtil can't resolve class under
osgi enviroment
ResolverUtil can't resolve class under osgi enviroment
------------------------------------------------------
Key: CAMEL-577
URL: https://issues.apache.org/activemq/browse/CAMEL-577
Project: Apache Camel
Issue Type: Improvement
Reporter: Freeman Fang
in method of
protected void find(Test test, String packageName, ClassLoader loader)
it try to load class from directory or jar, it works for standalone mode.
But if the classloader of the method is osgi bundle class loader, it will fail since the getResource(packgename) return neither directory nor jar
for example, package name is org/apache/camel/convert, then what returned is /org/apache/camel/convert, so both loadImplementationsInDirectory and loadImplementationsInJar doesn't work in this case

Hi Claus,
Yes, I have tried it with ServiceMix 4.0 which is osgi container and it works well.

-----------------------------------
Freeman, why are you returning early if its a spring delegating bundle loader?
{code}
+ if (loader.getClass().getName().equals("org.springframework.osgi.util.BundleDelegatingClassLoader")) {
+
+ return;
+ }
{code}
Is it because its loaded using bundles before, if so could you not return just after the loading from bundle, or move the check into that code, so its nearly the bundle stuff.
At least I think there should be some comments in the code why we return only for this osgi classloader.

Cheers Freeman, as you are on top of the ServiceMix and thus works with an OSGi kernel where you can test it for real.
And hopefully it fixes some of the related issues as well.

Hi Claus,
You are correct
This code
+ if (loader.getClass().getName().equals("org.springframework.osgi.util.BundleDelegatingClassLoader")) {
+
+ return;
+ }
shouldn't be in the patch at all. I forget to remove it after the change to avoid using hardcode classloader name
I will re upload a new patch soon, so for it

Freeman, can you provide a patch to fix it or any more hint/helps? Or attaching a small sample project that illustrates the bug/problem in Camel.

Claus Ibsen commented on CAMEL-577:
-----------------------------------
Guillaume, thanks for reporting this.
What would be a good strategy to resolve this?
A quick idea is having a new OsgiResolverUtil class that ResolverUtil could resort to if it should load in bundle?
Since Camel detects if it should try bundle without having hard dependecy this is doable:
{code}
Method mth = loader.getClass().getMethod("getBundle", new Class[] {});
if (mth != null) {
// it's osgi bundle class loader, so we need to load implementation in bundles
if (LOG.isDebugEnabled()) {
LOG.debug("Loading from osgi buindle using classloader: " + loader);
}
loadImplementationsInBundle(test, packageName, loader, mth);
return;
}
{code}
The loadImplementationsInBundle could be in the new OsgiResolverUtil so its only loaded if using OSGi bundles. And thus the class loading issue should not happend.
And we could catch the NoClassDefFoundError and output a user firendly message that org.osgi.core should be an dependency.
And how do we configure it to be optional in the camel-core pom.xml? Currently it is:
{code}
<dependency>
<groupId>org.apache.felix</groupId>
<artifactId>org.osgi.core</artifactId>
<version>${felix-osgi-version}</version>
</dependency>
{code}
Could we add
<optional>true</optional>
BTW: The activation stuff is now also a hard dependency - i haven't seen this in pom.xml

Hi
Just a very quick glimpse. I gotta do some work for the client so cant peek to much.
Isn't there a stable OSGI pendency for felix that can be used instead of 1.1.0-SNAPSHOT or whatever it was?
And are we sure its the spring osgi bundle classpath loader that is used all the time?

-----------------------------------
Freeman, I dont suppose I could ask you to try again with TRACE level debugging in org.apache.camel.util.ResolverUtil.
I would like to see if the trace logging is useable in situations to resolve problems. Especially of the osgi logging is useable, eg. the logging of the bundle toString() itself - does it provide a good toString() implementation or do we need to log: bundleId, symbolName, and whatever can be relevant.
If you could paste the logging output here would be super great.

-------------------------------------------
Also without dependency to org.apache.camel.converter package everything works fine, but there are even more error reports. Probably class loaders are checked in wrong order.

Hi
Just a very quick glimpse. I gotta do some work for the client so cant peek to much.
Isn't there a stable OSGI pendency for felix that can be used instead of 1.1.0-SNAPSHOT or whatever it was?
And are we sure its the spring osgi bundle classpath loader that is used all the time?
Med venlig hilsen
Claus Ibsen

Woljciech.
Do you mind creating a new ticket for your issue and attach a sample project that demonstrates the problem?
Please note what container and versions you are using and how to reproduce the problem.
Then we will be in a better position to address this for Camel 1.5

------------------------------------
re upload the patch
use 1.0.1 instead of 1.1-SNAPSHOT in the pom
also avoid hardcode classloader name, if the classloader has getBundle method , then it's an osgi bundle classloader

Leaving open until it is verified that it works in an osgi environment. Freeman are you able to try it out?
