Hi,

I'm fighting to get JBuilder 2005 to compile and execute code samples from
Sun. In the main the compiler errors indicate missing symbols for both code
samples. The code samples are JavaSoundDemo and those with the commapi.

I'm creating new projects and including all the source code then making,
rebuilding and running. In general the errors come about when making and
attempting to execute since that remakes the files. Few classes build
without error and produce java code.

I have checked and rechecked the location for the supplied dll, jar and
.properties files and possibly have them in other places to to cover the
options. I've tried to explicitly include references to the jar files that
come with the samples thinking that there's some important library missing.


I can run the bytecode as supplied so it seems that the environment is
close to being what it should though not entirely right since the
serialDemo does not see the PC's ports and the soundDemo does not show any
midi voices.

I am aware that the CLASSPATH needs setting up by pointing to the
directories with the .jars located. I'm not sure if the CLASSPATH requires
the .jar in the path statement.

I had some luck trying to get this working and at one point the SerialDemo
seemed to work after altering the CLASSPATH. Chasing a similar result for
the JavaSoundDemo I have the sound demo running but the Serial demo doesn't
work now! 

I'm not sure what changed and all attepts seem to fail.

I note that the JavaSoundDemo requires the classes unpacking from the .jar.
I assume that the unpacked classes should go in a directory in the
CLASSPATH and probably best in the project /classes directory. Is this
right?

I feel certain that there's a problem finding the javax libraries and
something is wrong with CLASSPATH.

I'd like to start using these samples as the basis of experiemntation and
development activity.

Please shed some light on what I'm doing wrong.

Cheers,

Philip
