This is a critical problem to me as compiling from Eclipse and from ant
via the command line causes classes serial version problems.

I tried setting all compile flags and options to be identical by I'm
missing something. If I could see how Eclipse compiles the class files,
I may remedy this problem.

You can see the compiler options used to compile your .java files in
Window->Preferences->Java->Compiler.
Note these can also be set on a per-project basis: Project->Properties->Java
Compiler.

There is no such thing as a command line in this case because the compiler
is part of eclipse.

That's the usual phenomenon when using different compilers. AFAIK there
are some issues in the language spec that make serial version generation
underspecified, i.e., different compilers may generate different version
ids for the same souce.

The great law of serialization: You must not mix classes compiled by
different compilers!

This is especially true if you use applets in conjuction with
serialization and compilation of server and client with different
compilers.

see above.

Different compilers also means different versions of the same compiler
(javac 1.3 compare to javac 1.4 for example.

However the Eclipse compiler could be used in batch mode.

About serialization, there is no portable solutions between compilers
than setting the SerialUID inside each class for which you want to
serialize instances.

Setting SerialUID is that best option at any rate.
