Subject: What is this error?
I don't understand this error, what am I doing wrong? This is the alpha
3 version.

You must call the superclass constructor as the first thing in a
method. Since you didn't do that, the compiler used the default
constructor with no arguments, which of course doesn't exist in Frame.

Subject: invoking javah and javap
In the "Implementing Native Methods" example, I'm unable to apply either
javah or javap to the class files I generate with javac. When I try
to execute
javap demo.File
for example, javap reports it can't find a class called demo.File.
I've confired that this isn't a CLASSPATH problem, and I've tried
every permutation of options and class names and I can think of.
Interestingly, javah and javap work fine on classes in hotjava/classes/...
You should say:
javap <classname>
e.g.,
javap java.lang.String
Also, while I'm at this: is it really possible to execute native methods
using the NT alpha2 release? I seem to recall someone mentioning that
a critical .dll is missing from the release.
Yes, this works.

Subject: Re: what is wrong with an answer that has C++ sucks in it?
Sorry, I keep hoping that the Java team folks will start particpating in
this forum again... :-(
Instead they are working 15 hours a day getting the beta version ready
for release.
It seems that the Sun Java team doesn't have the
time/energy/bandwidth/etc. to deal with all of the issues that
they need to address so they have prioritized their list of
issues. The standalone Java support seems to have been placed
relatively low on their list. :-(
Yeah, but Sun is a big company, and they might have other parts of the
company, that has practice creating development enviroments, working on
some of the other aspects of the language. The Java team is working
on the technology at its lowest level. Some of the other 12000 Sun
employees are working on the rest.
