ECF container does not get activated with Gemini Blueprint [message #1005456] Fri, 25 January 2013 09:15 Go to next message

We have been evaluating the Eclipse Communication Framework (ECF) with Declarative Services and Blueprint. While with DS works ok, when using Blueprint the ECF container does not work. All the required bundles for Blueprint have been installed:

- org.aopalliance
- org.apache.commons.logging
- org.eclipse.gemini.blueprint.core
- org.eclipse.gemini.blueprint.extender
- org.eclipse.gemini.blueprint.io
- org.springframework.aop
- org.springframework.asm
- org.springframework.beans
- org.springframework.context
- org.springframework.core
- org.springframework.expression

The blueprint appears as active but nothing gets published. Switching to DS (with the respective changes in the bean configuration under OSGI-INF and the manifest file) makes the ECF remote service available again. Is there something else we should do? We are seeing this even when modifying the examples found at http://git.eclipse.org (org.eclipse.ecf.examples.remoteservices.hello.ds.host and org.eclipse.ecf.examples.remoteservices.hello.ds.consumer) which work perfectly fine with DS.

Hi Joerg,

Simply put, I don't immediately know what's going wrong here. It clearly has something to do with Blueprint's behavior...probably WRT the ECF remote services impl...but I do not know how Blueprint works.

If you are game, I'll help figure this out if you can gather information (through testing your code + Blueprint). But first, have you asked this question on any Blueprint forum? Any insight from that?

Next, it would be helpful if you could paste in a listing of all bundles in your runtime...and their states (e.g. resolved, active, etc)...e.g. by using the OSGi console 'ss' command. What I'm looking for is what the status is of the ECF remote services implementation both before and after Blueprint is supposed to register the remote service. I also want to make sure that you have all the necessary ECF bundles in your running framework.

We can use this forum for interaction, but if you wish it might be useful to have this discussion on the ecf-dev mailing list (see here to sign up):

https://dev.eclipse.org/mailman/listinfo/ecf-dev

That is a more technical list, and it is monitored by more ECF committers (and their help might be useful...as they may have more familiarity with Blueprint than I do).

Thanks,

Scott

Hi Scott,

I appreciate your reply and effort to seek a solution.

The simplest way to analyze this would be to get the hello example to work with blueprint. I think the DS example is the most appropriate given that, from my experience, DS is quite similar to Blueprint in structure. Got it from the git repository org.eclipse.ecf under examples/bundles. This way, once we get it working it could also be submitted as an additional example on the repository.

First the host bundle (org.eclipse.ecf.examples.remoteservices.hello.ds.host) which I can start using the included product file. Once it is started, I can also view the endpoint in the Service Discovery tab within Eclipse (listed as ecf.osgirsvc). The consumer is not started yet. In this DS invocation the bundle list is as follows:

Then org.eclipse.ecf.examples.remoteservices.hello.ds.consumer is started and proceeds to succesfully perform the remote calls. Its bundle list is as follows:

With the above working as expected we proceeded to make changes to introduce Blueprint activation (and remove DS).

No errors are reported during startup. However, the service does not get published and the consumer cannot perform the remote calls. Also, nothing appears under Service Discovery in Eclipse. Tried with different startLevels, configurations, etc. but no dice so far.

I can also post the consumer-side changes but I think it's wiser to resolve the above issue before proceeding further.

Thanks,
Joerg

org.eclipse.gemini.blueprint.extender_1.0.0.RELEASE is RESOLVED so Gemini Blueprint's extender is not operational. You need to start it.

Thanks for the tip Glyn.

After adding the following line in the product configuration (having removed the blueprint.core auto-start):
<plugin id="org.eclipse.gemini.blueprint.extender" autoStart="true" startLevel="0" />

Gemini Blueprint does get triggered, but throws this error:
SEVERE: Unable to create application context for [org.eclipse.ecf.examples.remoteservices.hello.ds.host], unsatisfied dependencies: none
org.springframework.beans.factory.BeanCreationException: Error creating bean with name '.org.eclipse.gemini.blueprint.service.exporter.support.OsgiServiceFactoryBean#0': Initialization of bean failed; nested exception is java.lang.NoSuchFieldError: NULL

This looks similar to https://bugs.eclipse.org/bugs/show_bug.cgi?id=375225 and we assume we should upgrade to Gemini Blueprint 1.0.2.RELEASE (btw, we are using Spring Framework 3.1.1.RELEASE). Correct?

OK, after adding Gemini Blueprint 1.0.2.RELEASE:

INFO: Application context successfully refreshed (OsgiBundleXmlApplicationContext(bundle=org.eclipse.ecf.examples.remoteservices.hello.ds.host, config=OSGI-INF/hello.xml))

The application also successfully appears under Service Discovery.

I will proceed to the consumer-side adaptations and let you know.

Thanks!

With the above adaptations the synchronous remote call via proxy completes successfully using Gemini Blueprint.

However, the asynchronous remote call with callback fails with:
WARNING: Custom method [public void org.eclipse.ecf.examples.internal.remoteservices.hello.ds.consumer.HelloClientComponent.bindHello(org.eclipse.ecf.examples.remoteservices.hello.IHello)] threw exception when passing service [$Proxy2@58714e00]
java.lang.ClassCastException: $Proxy2 cannot be cast to org.eclipse.ecf.remoteservice.IRemoteServiceProxy


After looking into this it appears that when using DS the proxy instance is of type org.eclipse.ecf.provider.remoteservice.generic.RemoteServiceImpl whereas with Blueprint the proxy is of type org.springframework.aop.framework.JdkDynamicAopProxy (thus the ClassCastException). I'll keep looking... any advice is welcome.

I'm pretty much stumped. The way I understand it ECF remote service proxies are supposed to implement the IAsyncRemoteServiceProxy automagically. In this case the result would be to have a proxy that implements the IHelloAsync interface as well. This works when using Service Tracker or DS activation but I can't tell why this does not happen when using Blueprint.

Would that be part of the proxy creation code within ECF or is it within Gemini Blueprint?

Thanks!

When using DS the proxy is created by ECF and in particular org.eclipse.ecf.remoteservice.AbstractRemoteService$ProxyClassLoader. The createProxy() methods seem overly likely (even though I haven't verified through a debug session yet).

The generated instance implements the following interfaces:

interface org.eclipse.ecf.examples.remoteservices.hello.IHello,
interface org.eclipse.ecf.examples.remoteservices.hello.IHelloAsync,
interface org.eclipse.ecf.remoteservice.IRemoteServiceProxy

When using Blueprint the proxy creation appears to be handled through Gemini Blueprint only, involving the org.eclipse.gemini.blueprint.context.support.internal.classloader.ChainedClassLoader.

In this case the generated proxy implements the interfaces:

interface org.eclipse.ecf.examples.remoteservices.hello.IHello,
interface org.eclipse.gemini.blueprint.service.importer.ImportedOsgiServiceProxy,
interface org.springframework.aop.IntroductionInfo,
interface java.io.Serializable,
interface org.springframework.core.InfrastructureProxy,
interface org.springframework.aop.SpringProxy

Should the proxy creation have been delegated to ECF in the second case? Is there a way to cause this?

I'll put together a post to the Gemini forum as well.
