Need help linking NXT file

[aikmin]

I am using eclipse 3.2 on a Windows XP machine and i am having trouble linking NXT files. I am able to compile the java file, and i am able to download the sample .bin files into the NXT, but not able to link my java file. I am getting the following error

java.lang.NoClassDefFoundError: js/tinyvm/TinyVM
Exception in thread "main"

I tried several version of java including 1.4.1_02, 1.4.2_10, 1.5.0_10, and 1.6.0. I also tried is on the command prompt, and i am getting the same error, so it is not something i did wrong on eclipse. Any help would be great. Thank you.[/quote]

I got it to work by recompiling the source files and the replacing the jtools.jar file with the new class files.

I am trying to use Eclipse to control the NXT in java. I've downloaded the lejos_nxj files, started a new project in Eclipse and brought in all the files to that workspace, but I suppose it's much more comlicated then that to actually get things started. Could you give me a few pointers?
thanks

Here is an ant build.xml file that will compile and link a lejos NXJ program in Eclipse. Just set the lejos_home property.

<project name="Tune" default="link" basedir=".">

<!-- set global properties for this build -->
<property name="lejos_home" location="" />
<property name="src" location="."/>
<property name="program" value="Tune"/>
<property name="binary" value="${program}.bin" />
