I'm trying to create a "javah" command that behaves like the "javaw"
command on Windows, so that when a user double-clicks a .jar file it
launches. I've created a shell script that does the job pretty well, and
a RDEF to go with it.
"javah" is already taken (by the JNI header/stub generator). And the
purpose of javaw on Windows is actually just to start a non-console
application (a problem that doesn't exist on Haiku). It has only
indirectly to do with starting JARs on double click.
Anyway, a separate application -- a real application, not a script --
could do the trick of running a JAR. However, that is really only a
solution for this situation. There are similar ones that have the same
issue.
What is missing in Haiku is an option to associate a file type with a
command line instead of a preferred application. For JAR files one would
simply set "java -jar %f". This would also be a solution for all file
types where the handling application would actually be a script.
However, how do I add the attributes from the RDEF to the shell script?
Xres corrups the file (obviously). I can copy a preexisting binary file
(e.g. cp), xres the compiled RDEF onto it, and then "copyattr" to the
shell script, but that's more a hack than a real solution...
The procedure is: 1. rc to resource file, 2. use resattr to add the
resources as attributes. However, then you have the usual application
attributes on a script, but I believe that doesn't help you with setting
the script as a preferred application for a file type. I'm fairly sure
BMimeType and/or BRoster check that the file is actually an application.
