RE:SOLUTION FOUND [Asterisk-java-users] Is this a bug?

[Jason W. <jas...@be...>]

I finally found the problem listed below and wanted to communicate it
because perhaps it will be a help to others.

I had reset the classpath on the machine, and it was not correct(typo).  I
was able to run all types of simple java programs so I thought that this
couldn't be the problem.  However, I was not able to concatenate strings.
Someone on the groups told me that the chance of the program failing on that
line (where the concatenation was) was 0%. Saying the chance of anything
failing is 0% is probably never appropriate, as there is always a
possibility, and in this case, was the direct key to the problem.

The class needed to perform string concatenation couldn't be found at
runtime and therefore the DefaultAGIServer just hung, and then gave a severe
error on subsequent requests. Is there a way to simply change the way this
server works so that it would give detailed error information to the screen
when this type of thing happens? would this be a worthwhile change? I had
the code in the agi in try-catch blocks, with a system.out of the exception,
but didn't see this on the screen. running the program in main I was able to
see the problem, so I'll do this quicker next time. perhaps this was more
about honing my debugging technique than anything else! :)

Thanks again Stefan for your hard work on Asterisk-Java.

what JDK are you running on that machine? a sun one or some of the
"free" ones like kaffee that sometimes come shipped with linux distros?
try a java -version
You probably want to make sure you are actually running a recent sun (or
bea jrockit) jdk there.
