Referring Bill’s post below that 2
MDRs and 2 data managers work in the OSGi environment …
Can some one let us know the bundles that need
to be picked up, to bring all 4 entities (2 MDRs and 2 Data managers) up and
running within eclipse-OSGi environment?
Despite picking all bundles given under
cosmos-demo\DataManagers\configuration\config.ini file, we couldn’t bring
them up and running under eclipse- OSGi environment.
Also this wiki page http://wiki.eclipse.org/COSMOSDataCollectorEnvironment,
seems outdated. Can someone update this page?

Some kind of silent dependency on org.w3c.dom something?
I agree it is very weird because as you mentioned the other MDRs which work
have this.

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:

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.

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.

RE: Build issue

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.

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.
