Hi,

i'm using ANT 1.6.5 on Linux (same for JDK 1.4 or 1.5).

I have written an own task, inside this i use
java.util.logging.
When i want to load my own logging handler it fails:

[xmlBlasterScript] java.lang.ClassNotFoundException: 
org.xmlBlaster.util.log.XbNotifyHandler
[xmlBlasterScript]      at 
java.net.URLClassLoader$1.run(URLClassLoader.java:199)
[xmlBlasterScript]      at 
java.security.AccessController.doPrivileged(Native Method)
[xmlBlasterScript]      at 
java.net.URLClassLoader.findClass(URLClassLoader.java:187)
[xmlBlasterScript]      at 
java.lang.ClassLoader.loadClass(ClassLoader.java:289)
[xmlBlasterScript]      at 
sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:274)
[xmlBlasterScript]      at 
java.lang.ClassLoader.loadClass(ClassLoader.java:235)
[xmlBlasterScript]      at 
java.util.logging.LogManager$5.run(LogManager.java:783)
...

The java.util.logging.LogManager.java uses following code:

 Class clz = ClassLoader.getSystemClassLoader().loadClass(word);

It seems the system class loader does not find my XbNotifyHandler class
even that it is definitely in the CLASSPATH,
i have also tried
 <typedef >
 <classpath> <pathelement location="..."
and -lib

with no success.

But this is works fine:
 Class clz = 
Thread.currentThread().getContextClassLoader().loadClass(cname);

but i can't change the java.util.logging code to use the ContextClassLoader! 


How can i resolve this issue?

thanks
Marcel
