Hi Joel,

We don't need to call. I will update the manifest files, and start a build. I know there is code checked in for the UI as well. Let's all check the next build.

My current theory of the problem is that if a class has the class Element in a method signature, the class reflection fails to find the Element class. It may be a classloader problem.

I will now work on tweaking the manifest file settings...

Give me a shot if you know how to fix it!

Subject	RE: Build issueLink

I confirmed John's finding that the program stops at

Method methods[] = resourceClass.getMethods();

where resourceClass is the LoggingDataManager's class object.

I added the following two lines at AbstractDataManagerActivator, right before we call contribution manager. The program stops at this getMethods() call as well.

Method[] methods = dataMgrImpl.getClass().getMethods();
System.out.println("number of methods: " + methods.length);
manager.manage(dataMgrImpl);

So there is something strange about this class, but I have no clue what that is.

Note the EPR printed. There should be one EPR for each MDR or data manager in the container. When I run the build, I only see two EPRs, printed. The EPRs two new data managers are not bound.

I don't see any stacktrace.

Subject: RE: Build issue

Hi all,

Here is an update of my findings. I can't pinpoint the location yet, but I found that a change in the managed operation method signature can make a difference.

I created a test program with a very simple data manager. See attached file. The capability interface "ITest" has only one method. The EPR of the data manager is bound if the capability has the following operation:

@ManagedOperation
public String test(String x) throws CosmosException;

However, if I change the return type to Element, then it doesn't work.

@ManagedOperation
public Element test(String x) throws CosmosException;

It's strange because there the IQuery interface has a capability that returns Element, and MDRs work.

You can play around with my test case. Unzip datamanager.zip it to the DataManagers/plugins directory. And update the config.ini to append the following string to the first line:

plugins/datamanager_1.0.0@start, plugins/datamanager.common_1.0.0@start

Source code of the 2 modules are in the code.zip. You can import them to your workspace:

Subject	RE: Build issue

Hi Joel

To summarize the problem: we have 4 data managers, 2 are mdrs (Example & SML) and 2 are data managers (CBE & Stat). All of them work within osgi. But outside of osgi, only the 2 mdrs work. JT traced the failure of the 2 data managers outside osgi to the resourceClass.getMethods() line in ManagedProxyInvocationHandler.java (using tedious println statements). There was no actual failure exception thrown; instead the println after the getMethods was never reached. So it appeared that getMethods() hung the thread. Since this hang occurred while processing the annotations, we thought you could help identify the cause and provide a resolution.

Hope this helps.

Regards
Bill

Hi Joel,

We are using org.eclipse.equinox.ds taken from orbit. I don't know who implemented it.

You can download the build from here:
http://www.eclipse.org/cosmos/downloads/

The last two developement builds should be good. I am running with COSMOS-1.0.0-200801142344.

Subject	RE: Build issue

Hubert,

From what I understood (wrongly – it appears), you were getting the stack trace during registration whenever you ran. It wasn’t clear to me that this only occurs running outside of OSGi. When I ran, I got a different exception, which I attributed to some sort of race condition. When I flipped the implementation over to use declarative services on both ends, everything registered fine.

Looking at your code, I agree that it should work – I’m wondering if it’s a problem with the equinox declarative services implementation, where the service registration event is going out before the service is actually initialized. In the binding code, I use the activate call to initialize muse, and I’m wondering if DS is sending the registration event prior to the activate returning.

IIRC, ProSyst had donated a production-strength implementation of DS to equinox – is that the one we’re running with?

Can you point me to your current build?

Thanks,

Joel

Subject: RE: Build issue

Joel, can you briefly summary your findings on what caused the problem?

The proposed change is pretty big. It changes the programming model and affects existing data managers.

The reason why I didn't use declarative service is because I didn't want every developer who need to create a data manager or MDR to create a component XML, and let the framework handle the osgi service related details. I will look for a simpler solution.

I had a look at the patch, though some of it is greek to me.
The problem is that its not as easy as applying the patch to workspace and trying it out, because my workspace already works just fine,
Its what the build generates that is a pickle, so there is some environmental factor involved.

Subject: Build issue

We tracked why the CBE and Statistical datamanagers don’t get registered to some kind of annotation issue.

Where it gets stuck is in ManagedProxyInvocationHandler.processAnnotations() trying to get the methods of the datamanager class

Method methods[] = resourceClass.getMethods();

It does not return from this call

Here’s how it got there.

I tried to figure out what’s different about these datamanagers from the ones that get registered but did not turn up any substantive leads.

I have no idea why it can’t get the methods of the class, or why it does not return (instead of throwing an exception)

We noticed that if we call getDeclaredMethods() instead, it comes back but then hangs on a getAnnotation() call on the first one it finds.

I need help figuring this out.
