To work my way through the Cattle Drive Servlet area, I installed OrionServer 1.4.5 in NT environment. The unzipped orion folder is located in the root directory and I copied tools.jar into that folder. From c:\orion, I run java -jar orion.jar and the startup fails. I get an exception in main; java.lang.VerifyError: (class: com/evermind/server/ApplicationServer, method: ux signature: ()V) Incompatible object argument for invokespecial. Any ideas what the problem is?
