add an empty directory "ext" under ...\lib.
That would solve your problem.

Subject: Jikes + weblogic

Hello,

I am using Weblogic, and trying to use Ant with Jikes. Jikes from command line works, Ant with javac works, but when I insert the line

<property name="build.compiler" value="jikes"/>

to my build file, Ant reports an error:

c:\work\antproba\build.xml:7: C:\bea\jdk130\jre\lib\ext not found.

Do you have any idea why does it happen? 
I searched the list for the answer, but couldn't find it, so please be patient if the answer is well known.

Thanks in advance,
Don
