Re: [Springframework-developer] Spring Framework 2.1 M1 released

I agrea with all those arguments and the fact SUN JDK 1.3 is not supported
anymore.
My customer still uses a shared websphere 5.0.2 for its apps with no
migration plan, so I need Java 1.3 compatibility that gets difficult to get
with many frameworks.
Is the javac ant task targetted to 1.3 class format ? This could make spring
2.1 usable (but unsupported) on java 1.3
