Dynamic Class Reloading

[kallin]

A feature I've come to rely on in java 1.5/1.6 development is the ability to recompile a class in IDEA/eclipse while debugging a remote JVM, and have that class reloaded in that remote JVM. When I try this on the WTK JDK I receive unsupported operation exceptions. Is it really impossible to do this with this minimal JVM, or am I just missing something?

I've never even attempted it before. My *guess* is that it won't work for J2ME. The classes are all verified before running, and that probably messes up any chances of doing what you suggest. Anyone else doing something similar?

You don't know what you're missing out on Adam . With a 'hotswap' capable jvm, you rarely need to restart an app unless you're making major structural changes. There's also the ability in eclipse/idea to open up a dialogue box when you've hit a breakpoint and write arbitrary code with access to all variables in scope. I guess i'll just have to learn to live without it...

That does indeed sound useful. It's been years since I've done any proper debugging. I currently make ample use of System.out.println()
