Sorry about the OT question, but how did you extract the
implementation-version info? Running in winxp, suns' sdk 1.4.2, I get null
whenever I try to get the info. Maven built the manifest correctly, but my
app can't get the info. Here's what I've tried:
//these two give me null for the implementation version
MyClass.class.getPackage().getImplementationVersion();
this.getClass().getPackage().getImplementationVersion();
//this gives me a NPE on the getPackage() call.
Package.getPackage("maven version info").getImplementationVersion();
I've gone through several forums enteries, but haven't got code working so
far. Appreciate any help or direction!
