problem verifying

[nimbus12345]

hi,

I've installed jdk1.4 and wtk2.1 and tried the Animation example from the PDF document "Using Ant and Antenna" from the nokia pages.

It compiles well, after I inserted the line
<property name="bootclasspath.dir" value="d:\wtk21\lib\cldcapi10api.jar"/>
into build.xml - which is not stated anywhere (took me many hours to find that out!).

This is what Ant shows me in my command window (w2k):

D:\JAVA\Phase1>ant
Buildfile: build.xml

initialize:
[echo] Cleaning up...
[delete] Deleting directory D:\JAVA\Phase1\jclasses
[delete] Deleting directory D:\JAVA\Phase1\pclasses
[delete] Deleting directory D:\JAVA\Phase1\final
[mkdir] Created dir: D:\JAVA\Phase1\jclasses
[mkdir] Created dir: D:\JAVA\Phase1\pclasses
[mkdir] Created dir: D:\JAVA\Phase1\final

compile:
[javac] Compiling 3 source files to D:\JAVA\Phase1\jclasses
[javac] D:\JAVA\Phase1\src\AnimateTimerTask.java
[javac] D:\JAVA\Phase1\src\AnimationCanvas.java
[javac] D:\JAVA\Phase1\src\Animation.java

preverify:
[exec] Error preverifying class java.util.TimerTask
[exec] java/lang/NoClassDefFoundError: java/lang/Runnable

package:
[jar] Building jar: D:\JAVA\Phase1\final\Animation.jar
[copy] Copying 1 file to D:\JAVA\Phase1\final

run:

BUILD SUCCESSFUL

Preverifying doesn't work - anyone know what I'm supposed to do?

Thanks in advance!

for my case, I insert both the CLDC and MIDP classpath in the 'bootclasspath" environment variable.
I was wondering what ver of JDK r u using, is ur JDK ver 1.4.2_03 ? Cause I found some problem with this version ... emulator installation program can't detect it! May be it's something doing with this ver. of JDK too(i face other similar problem too).
