[jira] Created: (TUSCANY-1293) SDO does not work with OSGi
SDO does not work with OSGi
---------------------------
Key: TUSCANY-1293
URL: https://issues.apache.org/jira/browse/TUSCANY-1293
Project: Tuscany
Issue Type: Bug
Components: Java SDO Implementation
Affects Versions: Java-SDO-beta1
Environment: OS X Eclipse 3.3 M7
Reporter: Bryan Hunt
Priority: Blocker
When I execute:
XSDHelper.INSTANCE.define(schema, null);
I end up with a NullPointerException. I've tracked down root cause ...
The static initializer of the HelperProvider executes this code:
provider = getInstance(HelperProvider.class.getClassLoader());
which ends up calling:
HelperProvider provider = loadImplementation(cl, implName);
implName is null so
if (implName == null) {
implName = getImplementationName(cl);
}
ends up calling
implName = getImplementationName(cl);
which ends up calling:
InputStream is = cl.getResourceAsStream(SERVICE_RESOURCE_NAME);
where SERVICE_RESORUCE_NAME = "META-INF/services/commonj.sdo.impl.HelperProvider"
getResourceAsStream() return null because META-INF/services does not exist in the API bundle. It exists in the IMPL bundle and since you are using the class loader from the API bundle, it won't work.
You can set
-Dcommonj.sdo.impl.HelperProvider=org.apache.tuscany.sdo.helper.HelperProviderImpl
to get around the above problem, but as soon as
return (HelperProvider) cl.loadClass(implName).newInstance();
executes, you get a CalssNotFoundException. Again, this is because you are trying to load a class outside the bundle with the wrong class loader.
tried modifying the API manifest by hand to add
Eclipse-BuddyPolicy: dependent
and
Eclipse-BuddyPolicy: global
Either of those buddy policies will get past the class loader problem (although I believe this is specific to eclipse and won't work for OSGi in general), but when HelperProvider is initializing, you get the following exception:

--------------------------------------
Do you want to go as far as automatically unregistering types when the bundle that contains the implementation classes becomes unavailable?

-----------------------------------------
Amita, I get clean build from a clean extraction. Looking at runSDOTests() for your run there ought to be 106 outputs to system.out of TestFalluire instances. Can you take a look at these, and attach to the JIRA please?

[jira] Updated: (TUSCANY-1293) SDO does not work with OSGi
Posted by "Rajini Sivaram (JIRA)" <tu...@ws.apache.org>.
[ https://issues.apache.org/jira/browse/TUSCANY-1293?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Rajini Sivaram updated TUSCANY-1293:
------------------------------------
Attachment: sdo-osgi.txt
The attached patch sets up HelperProvider implementation when the SDO implementation bundle is loaded (in its bundle activator). Tests for running SDO in a multi-classloader environment and inside a Felix OSGi runtime have also been added.

[jira] Commented: (TUSCANY-1293) SDO does not work with OSGi
Posted by "Kelvin Goodson (JIRA)" <tu...@ws.apache.org>.
[ https://issues.apache.org/jira/browse/TUSCANY-1293?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12567667#action_12567667 ]
Kelvin Goodson commented on TUSCANY-1293:
-----------------------------------------
Rajini,
sorry to take so long to get to this, and thanks for the patch. I'm working towards getting thsi in for the next release. I note a couple of occasions in the tests where an exception is caught, and then either output is made to the System.out, or the exception is ignored. Could you help me understand if in either of these cases the symptom is truly benign please? If so i will add a comment to the code. If not then I'll change to let the exception surface through the test infrastructure.
First is on OSGITestCase ...
// Start all the installed bundles
for (int i = 0; i < bundles.size(); i++) {
Bundle bundle = (Bundle)bundles.get(i);
try {
bundle.start();
} catch (Exception e) {
e.printStackTrace();
System.out.println("Could not start bundle " + bundle);
}

[jira] Updated: (TUSCANY-1293) SDO does not work with OSGi
Posted by "Rajini Sivaram (JIRA)" <tu...@ws.apache.org>.
[ https://issues.apache.org/jira/browse/TUSCANY-1293?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Rajini Sivaram updated TUSCANY-1293:
------------------------------------
Attachment: sdo-osgi-export-patch.txt
I have tried to recreate the problem with IBM JDK 1.4.2, 5.0 and 6.0, and the tests work fine with all of them with a clean build.
Based on the errors in continuum, the attached patch explictly exports/imports the packages that reported missing classes. I am not sure if they are sufficient to fix the test, but it is worth a try.

[jira] Commented: (TUSCANY-1293) SDO does not work with OSGi

Kelvin Goodson commented on TUSCANY-1293:
-----------------------------------------
I don't have a feel for how important this is for a next release, and like Frank I don't have OSGi experience. Can someone with a vested interest in this fix give an indication of the impact of this issue and ideally provide a solution. That way it would have a chance of being fixed in the next release.

[jira] Commented: (TUSCANY-1293) SDO does not work with OSGi

Frank Budinsky commented on TUSCANY-1293:
-----------------------------------------
Hi Bryan,
Like I said before, I don't know much about OSGi, but my guess is something must be missing from in the MANIFEST.MF file (some kind of extension/extension_point information) that would make the impl bundle visible to the api bundle. This is just my guess anyway :-)
Can you, or anyone with some OSGi expertise, please investigate and/or suggest a sollution, or better yet provide a patch?
Thanks,
Frank.

[jira] Commented: (TUSCANY-1293) SDO does not work with OSGi
Posted by "Rajini Sivaram (JIRA)" <tu...@ws.apache.org>.
[ https://issues.apache.org/jira/browse/TUSCANY-1293?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12568011#action_12568011 ]
Rajini Sivaram commented on TUSCANY-1293:
-----------------------------------------
The first block tries to run bundle.start() on SDO bundles and its dependent bundles (EMF). It will throw an exception if one of these bundles could not be resolved. There is a testBundle.start() outside the loop which has dependencies on SDO (and hence on its dependencies). So if an exception is thrown by the loop, the following testBundle.start() will throw an uncaught exception ,causing the test to fail. I put the code to catch and print the exception from the loop rather than fail at the first exception so that all the bundles which failed to resolve can be identified in one run, rather than have to rerun after fixing one-by-one. The tests shouldn't really throw an exception now anyway, so please feel free to remove the try-catch block if you prefer.
The second catch block corresponds to delegation to the parent classloader during ClassLoader.loadClass(), and the exception there is deliberately caught and ignored (the child classloader loads the class if the parent classloader cannot). So the try-catch is necessary, and the exception doesn't reflect a failure.

[jira] Commented: (TUSCANY-1293) SDO does not work with OSGi
Posted by "Bryan Hunt (JIRA)" <tu...@ws.apache.org>.
[ https://issues.apache.org/jira/browse/TUSCANY-1293?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12503417 ]
Bryan Hunt commented on TUSCANY-1293:
-------------------------------------
The fundamental issue is the use of class loaders. This project (and others like it - Hibernate) assume that there is a single class loader and that all necessary classes can be found using this class loader. This is fine until you want to use the technology with OSGi. OSGi mandates one class loader per bundle. When a class is loaded from a bundle, any classes the loaded class is dependent on must come from it's bundle, or a bundle that has been explicitly declared as a dependency it's MANIFEST.MF. When you package something like SDO or hibernate as a bundle, there is no way to declare those dependencies.
Eclipse has a "workaround" for this problem called the buddy policy. There are various types of buddy policies that I won't discuss as you can find a much better explination by a simple google search on "eclipse buddy policy". While this works for Eclipse, I don't believe it's part of the OSGi specification and won't work with other OSGi implementations.
For the sort term, you might consider removing the ability to build Eclipse plug-ins (OSGi bundles) from your pom. For the long term, you might consider re-architecting the class loader to be compatible with OSGi.

Re: [jira] Commented: (TUSCANY-1293) SDO does not work with OSGi

Do you want to go as far as automatically unregistering types when the
bundle that contains the implementation classes becomes unavailable?

[jira] Commented: (TUSCANY-1293) SDO does not work with OSGi
Posted by "Bryan Hunt (JIRA)" <tu...@ws.apache.org>.

-------------------------------------
I'll try to comment on this issue this weekend. I've been swamped with work lately.
> SDO does not work with OSGi
> ---------------------------
>
> Key: TUSCANY-1293
> URL: https://issues.apache.org/jira/browse/TUSCANY-1293
> Project: Tuscany
> Issue Type: Bug
> Components: Java SDO Implementation
> Affects Versions: Java-SDO-beta1
> Environment: OS X Eclipse 3.3 M7
> Reporter: Bryan Hunt
> Priority: Blocker
> Fix For: Java-SDO-Next
>
>
> When I execute:
> XSDHelper.INSTANCE.define(schema, null);
> I end up with a NullPointerException. I've tracked down root cause ...
> The static initializer of the HelperProvider executes this code:
> provider = getInstance(HelperProvider.class.getClassLoader());
> which ends up calling:
> HelperProvider provider = loadImplementation(cl, implName);
> implName is null so
> if (implName == null) {
> implName = getImplementationName(cl);
> }
> ends up calling
> implName = getImplementationName(cl);
> which ends up calling:
> InputStream is = cl.getResourceAsStream(SERVICE_RESOURCE_NAME);
> where SERVICE_RESORUCE_NAME = "META-INF/services/commonj.sdo.impl.HelperProvider"
> getResourceAsStream() return null because META-INF/services does not exist in the API bundle. It exists in the IMPL bundle and since you are using the class loader from the API bundle, it won't work.
> You can set
> -Dcommonj.sdo.impl.HelperProvider=org.apache.tuscany.sdo.helper.HelperProviderImpl
> to get around the above problem, but as soon as
> return (HelperProvider) cl.loadClass(implName).newInstance();
> executes, you get a CalssNotFoundException. Again, this is because you are trying to load a class outside the bundle with the wrong class loader.
> tried modifying the API manifest by hand to add
> Eclipse-BuddyPolicy: dependent
> and
> Eclipse-BuddyPolicy: global
> Either of those buddy policies will get past the class loader problem (although I believe this is specific to eclipse and won't work for OSGi in general), but when HelperProvider is initializing, you get the following exception:
