Re: unsupported class version error
MIke:
I unjar'd my app.jar yesterday and did `file Application.class` and it returned
version 49 - so it looked normal. I am running now though. On Eclipse's
'Installed JREs' preference pane, I checked "JVM 1.6.0 (MacOS X Default)." I
had previously selected 1.5 there. The compliance setting has always been at
1.5. But my next build ran.
The weird thing is that I haven't changed any JVM or java settings in recent
weeks. I have no idea why that change effected anything. I hadn't changed any
java settings recently. And I have no idea which classes I produced were
wrongly versioned since everything I looked at seemed correct.

Re: unsupported class version error
your bootstrap class actually loaded, so it looks like it's one of your other
classes ... In particular, I suspect your Application class is built 1.6, since
it's failing on the first defineClass call.
unjar your application jar and run
find . -name '*.class' -exec file {} \; | grep 50
I would add a source and target declaration to your wocompile step in
build.xml, or pass in -source and -target to ant. I don't think ant building,
even from eclipse, cares about your JDK setting.

Re: unsupported class version error
Exactly how did i spell it "WOBoostrap" like 5 times? That's weird ... Did i copy and paste it so i didn't have to keep typing it? This email is a mystery wrapped in an enigma (wrapped in a sausage, wrapped in a pancake). I'll attribute this to being sent at 11:36PM. Suffice to say, I meant WOBootstrap, with all of its T's. ms On Nov 11, 2009, at 11:36 PM, Mike Schrag wrote: > For anyone who is getting an unexplained UnsupportedClassVersion error at > startup -- unjar your WOBoostrap.jar and run file on the WOBoostrap.class. > George Domurot and I just discovered that there is at least one > WOBoostrap.jar floating around the intertubes that was built with 1.6 and has > a 50.0 version number.

unsupported class version error
For anyone who is getting an unexplained UnsupportedClassVersion error at startup -- unjar your WOBoostrap.jar and run file on the WOBoostrap.class. George Domurot and I just discovered that there is at least one WOBoostrap.jar floating around the intertubes that was built with 1.6 and has a 50.0 version number. Possibly this came from a Snow Leopard developer preview? This file comes from whatever machine performed your build and typically is found in /System/Library/ WebObjects/JavaApplications/wotaskd.woa/WOBoostrap.jar (though the precise location is defined in your wolips.properties). I don't know how widespread that 1.6 build is, but if you've got it, this might save you a lot of insanity. ms ___ Do not post admin requests to the list. They will be ignored.
