I'm running the VRTest server on Windows 2000...

I'm running the VRTest server on Windows 2000 and the client on Windows 2000 can connect to it okay. I'm running eDirectory 8.5 on NetWare 5.1. I'm trying the Java vrtest driver.

On sys:system\lib, I have the following files:

09/25/2000 08:41a              50,690 xds.jar

I used the .xml file to bootstrap the driver using the setup wizard running on the Windows 2000 client. When I click the start button for the driver, dstrace and my dirxml log show this error information:

DirXML Driver Initialization Error!

I've looked at the code, line 133 is the first trace call that shows
"TRACE: VRTest/Driver: Initializing driver shim..."

It's quite unclear why the driver fails to load. Seems there is some more stack information that is missing from the trace. Does the driver need to authenticate to the vrtest server? I don't see a userID or password anywhere in the documentation. My driver is NDS equivalent to admin.

Novell's Shon Vella, on the DirXML Development Team, responded as follows:

Get rid of vrtest_api.jar and replace vrtestdriver.jar with the attached version. There was a minor incompatibility between the original and 1.1.7b JVM used on NetWare (or more correctly a bug in the class libraries for that JVM.)

I also noticed that there are few things that you will have to adjust in the rules to get the driver to work that were not prompted for on the import.

On the driver object, you will need to set the IP address of the Windows 2000 server on the Driver Parameters tab.
The placement rule on the publisher channel needs to have DELILAH_TREE replaced with the name of your NDS tree.

This should get you up and running!
