Hello,
I've got the following
PROBLEM:
-org.eclipse.net4j.util.container.FactoryNotFoundException: Factory not found: org.eclipse.emf.cdo.server.queryHandlerFactories[ocl]
-Receiving this problem both when trying to use MySQL database and H2-database.
+ A previous topic told to check whether the bundle org.eclipse.emf.cdo.server.ocl is resolved/active (using $ss cdo in OSGi console)
148 RESOLVED org.eclipse.emf.cdo.server.ocl_4.0.100.v20130318-1729

- Running Kepler4.3M6Classic, installation of CDO 4.2M6 stable builds, using the bookmarks as given.
+ Server is installed and runs without warnings/errors. Followed a tutorial written by Vincenzo (RCPvision). The console shows that the server is started succesfully.

An internal error occurred during: "Find Papyrus models".

-adding plugins in run configuration
-adding plugins to the feature project containing the cdo-server.xml and product file.
-importing separate files into the cdo database:

extended by org.eclipse.emf.cdo.spi.server.QueryHandlerFactory
extended by org.eclipse.emf.cdo.server.ocl.OCLQueryHandler.Factory
I assume the exception is thrown in the class QueryHandlerFactory (contains:'String PRODUCT_GROUP ="org.eclipse.emf.cdo.server.queryHandlerFactories')
How do I solve this problem?
This is only a rough description of the problem. If more specific descriptions are required, let me know which output you need.

Can you set a breakpoint in org.eclipse.net4j.util.container.ManagedContainer.getFactory(String, String) and try to find
out what goes wrong there in your deployment? Maybe org.eclipse.emf.cdo.server.ocl or one of its dependency bundles can
not be activated...

I *suspect* that Papyrus internally uses OCL queries here and there. Christian (CC'ed) may want to comment on that, but
in the meantime we can focus on why the OCLQueryHandler can not be created in your server.

That looks OK. This plug-in requires
org.eclipse.ocl.ecore_[3.0.0,4.0.0). That dependency is also correctly
resolved, with its dependency tree?

Papyrus uses an OCL query to find the resources in the repository that
are Papyrus models (they contain a SashWindowMngr at the root). This
is used to present them as "models" in the browser with child nodes for
the resources that contain the DI, UML, and Notation content.

That is correct. But the problem with the OCLQueryHandler is not
something that I have encountered in my test configurations. What else
could it be than missing the Eclipse OCL run-time on the server side?

Hi, Dieter,
There may be an exception stack trace in the workspace .log file that
can help us to determine what went wrong for you. Perhaps you could
attach that?
Apart from this, the application that is the CDO server is
org.eclipse.cdo.server.app. In case it might help you, I attach the
launch configuration that I use to launch a CDO server for testing the
Papyrus CDO integration feature.
You don't need to create a product configuration to debug the CDO
server. Running the server application (as in the attached launch
config) should be sufficient.
HTH,
Christian

Hello,
The problem regarding stated above has been solved, it was indeed a matter of unresolved dependencies. By comparing the launch config you provided I've noticed some deps were missing. Now also found the 'validate plugin' functionality... Sorry for the inconvenience.
Creating models (with class diagram and basic types) in the repository ok now, add'n'save children (eg. classes) in model explorer and cdo-editor works also. Yet I'm facing a NullPointerException error when adding a class on the class diagram and then save the model.
The .log has been added (LOG.NullExcInitTable.txt). In attempt to debug (breakpoint on: cf. code below), the program keeps on breaking (+30 times) on BREAK1, showing a TimeoutRuntimeException (LOG.timeoutExcep.txt).
The ID of debug variable (DEBUG.NullExcInitTable.txt) "this HorizontalNonAuditClassMapping (id=4923)" increases but the amount of tables in the database (MySQL) stays constant. When I disable BREAK1, leaving only BREAK 2 on the next line, the NullPointerException at AbstractHorizontalClassMapping.initTable pops up.
table = database.getSchema().getTable(tableName);
if (table == null)
{
IDBSchema workingCopy = database.getSchemaTransaction().getWorkingCopy(); //BREAK1
table = workingCopy.addTable(tableName); //BREAK2
This occurs with both H2 (no password) and MySQL database (root user and password) (for mongo I'm getting a not yet implemented error).
Thanks,
Dieter

Don't worry. Plugins are a blessing when the deployment is okay and a PITA if it isn't :P

In the latest I-build we fixed some odd memory and thread leaks that caused TimeoutExceptions in our Hudson build. Can
you try out that build?
Your breakpoints sit on very new code which resulted from a major overhaul of the net4j.db framework. Unfortunately the
stack traces do no longer match the tip of the master branch. Can you reproduce them with the latest I-build?
