Hi,
I'm trying to use the CDO Provider in ECP. I run a CDO Server (I followed descriptions from http:/ /www.rcp-vision.com/?p=1285&lang=en). Also I installed the CDO Model Repository 4.2 from Market Place as well as MySQL Connector/J and also Net4j DB Framework MYSQL Adapter (and the H2 Adapter) from their update sites.
A simple headless Unit test runs successful for H2. When I provide the functionality of the Unit Test in my product via a Menu Command, everything is fine for H2, too. But for MySQL I get a nested Exception: org.eclipse.e4.core.di.InjectionException: org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1DiagnosticWrappedException: java.io.FileNotFoundException: 1 (Das System kann die angegebene Datei nicht finden). It is thrown, when I request a resource from the transaction. (The same code runs with H2 without any problems). The test is basically this:
CDONet4jSession session = new CdoTestHandler().openSession("launch");
CDOTransaction transaction = session.openTransaction();
CDOResource resource = transaction.createResource("TestRes");
Nevertheless I tried working with H2. When I start the product, I get a NumberFormatException:
java.lang.NumberFormatException: null

To avoid the NumberFormatException, in org.eclipse.emf.cdo.internal.workspace.CDOWorkspaceImpl I bypassed in loadProperties() the assignment of the timestamp property and set instead new Date().getTime(). It's a rough quickfix but it works...
After this fix and after adding a CDO Repository everything ssems to be fine. Collasping a repository, produces the following:
org.eclipse.net4j.util.container.FactoryNotFoundException: Factory not found: org.eclipse.net4j.connectors[null]

I can fix this issue, when I pass in org.eclipse.emf.ecp.cdo.core.createSessionConfiguration() my own properties. The ECPProperties are null and I'm not sure, where to define them.
String connectorType = properties.getValue(CDOProvider.PROP_CONNECTOR_TYPE);
String connectorDescription = properties.getValue(CDOProvider.PROP_CONNECTOR_DESCRIPTION);
String repositoryName = properties.getValue(CDOProvider.PROP_REPOSITORY_NAME);
Adding a Model Element to the project runs into several NPEs

I also tried the way with MySQL, here I have also some errors. The RegistryNotFoundException occurs also with MySQL, here my Quickfix works also. The NumberFormatException occurs not. But additionally I get a StringOutOfBoundsException, when I try to checkout a repository (after confirming the name of the new project). The exception occurs even for names with more then 80 characters.

The project is added in the Project Tree now. Expanding the created project shows only an Error as Element... Here also adding model elements produces a NullPointerException...
I'm sorry for this long post :/

Hi Felix,
I don't see an actual question in your long post but the stack traces indicate that the CDO Provider in ECP is not
working as expected for you. It's very long ago that I worked on this provider and right now (and most likely in the
coming months) I won't find time to work on it. Maybe this helps you to work around some problems:
1) The ECPProperties (IIRC.) in this case are set on the ECPRepository (either through a rightclick in the Repository
Explorer or programmatically).
2) I guess most problems would be in either the CDOProvider for ECP or in CDOWorkspaceImpl.
3) CDO is best tested by us with H2.
I fear if you want more help you need to ask more specific questions.
Cheers

But additionally I get a StringOutOfBoundsException, when I try to checkout a repository (after confirming the name of the new project). The exception occurs even for names with more then 80 characters.
