Hi,
First of all let me thank for the great work concerning CDO. I love it and it really made my live as a developer so much easier.
Currently I am developing an application using Eclipse RAP and CDO.
When I deploy my application (and CDO server) on my linux server, I get an Exception when trying to commit a CDO transaction:
ArrayIndexOutOfBoundsException: 105 in CDOIDUtils in line 510
Everything works fine if I deploy the application (and CDO server) on my local machine.
Connecting to the CDO Server (on my linux server) with the CDO-Explorer (from my local machine) works just fine.
But connecting from my locally deployed application to the CDO server on the remote machine also fails with the ArrayIndexOutOfBoundsException (by connecting i mean committing a transaction).
Any idea what direction to go for solving this problem?
Please excuse that I dont't have an exact stack trace or exact versions right now.
If needed I will post it as soon as I have access the application again (I am not at the office right now).
I was just hoping that someone maybe has an idea what the problem is.
I'm using Java 7
CDO 4.1 with Mysql 5.1
Tomcat 7
CDO Server is deployed as an eclipse application, my application is packaged as a war and run in Tomcat

Thank you very much for the kudos ;-)
It would be great if you write a little review at https://www.ohloh.net/p/cdo/reviews/new to make others aware of CDO.
Larger community is better code!

Once I wrote a demo server with a RAP config interface. Very cool.

That would be at this line in CDOIDUtil.read(ExtendedDataInput):
Type type = Type.values()[ordinal];
org.eclipse.emf.cdo.common.id.CDOID.Type is an enum with way less than 105 enum literals. That makes me think that
you're using different CDO versions at client and server sides. That can (and almost always will) lead to unpredictable
behaviour. The reason is that the underlying Net4j Signalling Platform uses a performance-optimized binary protocol that
relies on matching meta data and transfer logic being deployed at both ends. Newer Net4j versions do check the protocol
version number.

Please make sure that clients and server have the exact same CDO+Net4j versions (ideally same build) deployed. Does that
help?
