Re: failed parameter passing to main?

The initial problem:
>> I've got an application I normally launch with the following arguments
>> java -Xmx256m
>> -classpath "/myhome/Desktop/ice_junk/contigeditor.jar:/myhome/Desktop/
>> ice_junk/mysql.jar" contigeditor.ContigEditorApplet
>> "http://an.ip.address/ice/"; "another.ip.address" "mouse"
>>
>> I've tried to use the MRJ App builder to make this nice and
>> double-clickable. The program launches, but then shows a dialog
>> indicating
>> that it's getting the wrong number of parameters.

> You should also post what is in your MRJApp.properties file for us to
> figure out what is wrong.
>
> You can also try launching your app from the command line in Terminal
> with verbose launching. You need use the full path to the executable
> inside the .app package. Ex:
>
> prompt> setenv JAVA_LAUNCHER_VERBOSE
> prompt> /path/MyApp.app/Contents/MacOS/MyApp
>
> The launcher will then print out status information as it parses your
> MRJApp.properties file.

I've tried this two ways now: one with a "terse" form, where the class
paths and main() location were omitted from the passed parameters (since
they seem to be handled by the wrapper) and a verbose one where everything
is identical to the args above. For the verbose one, I should note that
I've also kept the original .jar files in the locations pointed to by those
args.

Some further details which may or may not be helpful - I'm not the original
author of this software; it's freely downloadable, and I'm just trying to
make it so that people in my lab don't have to fuss to much to get it to
run. The downside is that I can't tell you what exactly it is that main()
is looking for. Depending on which version of the args I use, the dialog
shows a different numbered error (the dialog is displayed by the java app,
so it at least finishes launching).

I've also tried launching this through Obj-C/NSTask and Java/Process, but
neither of those seem to handle the parameter list well, either.

Thanks,
Jay
