Hi all,

I have a problem that I have not been able to solve. I am currently developing on 10.6 (5.4.3) and attempting to deploy on 10.5 (5.4.3). Currently all my deployment machines are on 64-Bit Java 1.6 and I am hoping to keep it that way.

When I deploy the app on 10.5, running it manually on the command line launches it ok. Some errors do show up:

[2011-5-18 14:39:1 GMT-04:00] <main> The bundle <AppName> has malformed version number:

and I can see java 64 bit is being loaded

java.specification.version=1.6

java.vm.name=Java HotSpot(TM) 64-Bit Server VM

However, running it using WOMonitor (Apples) in combination with SpawnOfWotaskd.sh Logging addition (http://wiki.objectstyle.org/confluence/display/WO/Troubleshooting+wotaskd+and+JavaMonitor+on+OS+X) I get:

/Library/WebObjects/Extensions/xml-apis.jar

/Library/WebObjects/Extensions/

java.lang.UnsupportedClassVersionError: Bad version number in .class file

I have tried

• adding -d64 to additional arguments, which is pointless since the correct java version is loading

• embedding system frameworks and not embedding them

• switching to 1.5 compatibility which raise another error in a Math library I was using

I'm really not certain how to remedy this. Does anyone have any pointers as to what the problem is exactly?
