java-programmer, Jars built with JDK 1.3 and JDK 1.4 interoperating The Runtime Environment is JRE 1.4. The latest code I have written has
been compiled with JDK 1.4. However it depends on some packages written
and compiled with JDK 1.3. Is there anything to look out for in this
kind of setup or should I have to recompile the older code with 1.4? I
have tested the whole thing and it works, but I wanted some more
information. It is a swing code and I need the JProgressBar's
indeterminate state which is available only in JDK 1.4.

Any update is welcome. If there is any document explaining the above,
that would be perfect. I searched but I was not able to find any
reference.

Thanks
JS

This might help http://java.sun.com/j2se/1.4/compatibility.html but it
should be totally upwards compatible.
