Dave,
I had this exact same problem, you need to specify 1.4 in about 187
different places. I also found it helped to delete the 'build' folder
in your project and do a clean build.
Cheers

Moray,
thanks, that sounds reasonable and probably caused my problem.
However, I was getting strange error messages when I ran my app
(unknown Controller classes from nib file, used NSObject instead etc
etc).
This was due to a missing Java 1.4 "Target VM" configuration in "Pure
Java Specific" settings. Looks like you have to keep three settings
in sync.
merci beaucoup
Dave
I'm pretty sure XCode/Project Builder uses Java 1.3 by default, you
need to select 1.4 in the Target Settings if the Java stuff you are
using is only available in 1.4.
Cheers
Moray
Hello,
I have a Cocoa/Java class that is supposed to make use of Pattern/
Matcher. The project runs fine without the use of Java 1.4's regular
expressions, but if I
import java.util.regex.*;
and, in one of the methods,
Pattern p = Pattern.compile("aa");
Matcher m = p.matcher("aaaaa");
the application won't load. The error message I am getting isn't very
helpful:
ObjCJava WARNING:
jobjc_jvm_newObject(): constructor with signature ()V on class
DialogueManagerController failed (should morph the java exception)
2004-02-22 22:36:03.014 Mumo[11248] AppKitJava: uncaught exception
OBJCJava_RUNTIME_EXCEPTION ((null))
2004-02-22 22:36:03.015 Mumo[11248] AppKitJava: exception = (null
description)
I tried to trace the error in the XCode debugger, which showed that
there is a ClassNotFoundException for java.lang.CharSequence and
then a
PrivilegedActionException.
Btw, a small java app to test the regular expressions (without Cocoa
layer) works as intended. I should probably add that I'm trying to
do the above in a class that is instantiated in a Controller class
controlled by some Cocoa code.
That's where I'm stuck. I would very much appreciate the help of
someone
who's a little more knowledgeable with this stuff than I am..
I very much appreciate your help.
Dave
