Hello Experts,
I have Eclipse and JDT 2.1.3 on WinXP, and using JDK 1.4.1. I have a
simple test program that calls java.lang.Integer.toString(int). I set a
breakpoint in my test program before this method call. I launch the test
program in JDT debugger. Then I step into the
java.lang.Integer.toString(int) method (JDK source is available.) When
inside the java.lang.Integer.toString(int) method, however, the
"Variables" view tab in the Debug perspective is empty. How can I see the
local variables when stepping into such "standard" Java source files?
Thanks.

use this ant build file
And you should be OK.
I use it all the time (now on 1.4.2_04)

Hi,
Thanks for all the responses. Clicking on the build.xml attachment gives
'Object not found'/'Error 404'. Can you please re-post the build.xml or
email it to me?
