Yeah, the WO version you are using does not match what the app was written against:
Exception logging in User: com.webobjects.foundation.NSForwardException [java.lang.NoSuchFieldError] _EOGlobalModelLock:java.lang.NoSuchFieldError: _EOGlobalModelLock
Caused by: java.lang.NoSuchFieldError: _EOGlobalModelLock
at ZpdDB$UnbrokenEOModel.entityNamed(ZpdDB.java:41)
What version is installed on this machine? That field has been on EOModel for a while IIRC, since 5.4. Does that machine have 5.3 installed on it?

>> The very same code running against the same database works from Solaris. I have currently no easy access to the source (somewhere on a XP Machine). Any idea what could be wrong? For a test the customer has copied the xyz.woa directory to a different Sun workstation (where Apple WebObjects runtime has been installed) and tried it there with the very same exception. So it looks as if we miss something in the environment setup. Question is: What?
>>
>> Background: The customer has once (>4 years ago) asked me to port the application to the modern world but then cancelled the project. And now the old Solaris box is dying and the customer desparately needs a replacement deployment environment. About a dozen apps have been moved over from Soalris to OS X with no problem (all Wonder), just this baby refuses to work (no Wonder - pun intended). And of course we have no time now to Wonderize, recompile, and test things.
