Here's what I used when I had to upgrade to Java 1.5. Don't know if
these instructions still hold for Xcode 2.3, but it's worth a shot:
Double-click Application Server target in Xcode.
Select Java Compiler Settings.
Set Target VM version to 1.4
Set Source Version to 1.4
Add this to Other Compiler Flags:
-bootclasspath "$(LOCAL_LIBRARY_DIR)/Java/Home/../../1.4/Classes/
classes.jar"
Then, with the popup menu at the upper left, switch from "Settings
show [Development] configuration" to each of the other configurations
(Deployment, Webserver, Default, etc.) and make all the same changes
to the Target VM, Source and Other Compiler Flags.

Hi Patrick
I tried this and did not really help.
I thought it was correct but I tried this all the way back to 1.3.1
and did not address the situation..
Still the same error...
Is there a global way to set the compiler to use an earlier JVM

Hi All
I have been running an app on Tiger server + latest Webobjects
run environment and recently updated development to the latest
XCode 2.3
Now I have tried to build an existing running app and when I try
to start it I get a error - this runs on the client but problem
is when I upload to the server:
java.lang.UnsupportedClassVersionError: Application (Unsupported
major.minor version 49.0)
Any ideas what this could be?
Gino
The JVM on the target machine has encountered a classfile in JDK
1.5 format. This most likely means you built using the JDK 1.5
compiler, which became the default after a recent software update,
and the machine on which you are trying to deploy is still using
the 1.4.2 JRE. Since WebObjects has not (yet?) been qualified for
Java 5, you are best off rebuilding using JDK 1.4*, see also
