Woo hoo! I got my first skrev. :)

Hmm...I'm using the compiled classes. Do you mean I should recompile jxl
with a 1.4 JDK? There's probably a cool way of doing that, right? I mean
some way of recompiling all the code in jxl.

Hi folks -

I'm getting the following error when I attempt to create a Java program.
This is/was a working program - the only difference is that I am
attempting to use a newer version of jxl. What's up with the version
Is the a JVM level thing?


- Michael

javac -classpath /OpenSource/jexcelapi/jxl.jar MakeXLS.java
MakeXLS.java:23: cannot access jxl.write.NumberFormats
bad class file:
class file has wrong version 50.0, should be 48.0
Please remove or make sure it appears in the correct subdirectory of the
import jxl.write.NumberFormats;

You are trying to run it with Java 1.4, and it was compiled with and for
Java 6.

If at all possible consider compiling with a Java 1.4 JDK. Second
choices are compiling with Java 6 but telling to generate Java 1.4
compatible files. Third but slow, is to compile on the i :)
