IIRC, this can also happen if the JDBC driver can not be found. I think that is
the error message anyway...
This happens on Windows as there are usually multiple JVM installations of the
same version. WebObjects installs one, but IE also puts one (at least) under
c:\Programs\JavaSoft. You will need to find each and install the JDBC driver
into the JRE\Lib\Ext directory.

I've just installed Webobjects 5.1 on a Win 2000 Pro machine. When I
try to run any app that access a database, I get the following error.
Server exception: _obtainOpenChannel --

com.webobjects.eoaccess.EODatabaseContext@75d6ab: failed to open
database channel.
This happens with any app, whether it's one that I generate from the
Wizard or it's one of the example apps. EO Modeler accesses the
databases (both OpenBase and Oracle), without problems but any app that
uses the same model gets the above error.
I don't use WO under Windows, but I believe EOModeler requires an
older Java version than WO 5.1 meaning that one must install 2 different
Java versions under Windows. If you didn't install 2 Java versions,
this might explain what you're experiencing. I would think that the WO
installation instructions would describe this process.
