Tim,
once more, thanks a lot! To sum up both threads, and to verify that I
have correctly understood your brilliant idea, can you confirm that this
is what you want me to do:
* Create a Workaround.jar file that contains nothing but a
META-INF/MANIFEST.MF file.
* The META-INF/MANIFEST.MF file contains the declaration of
"WorkaroundExtension".
* The META-INF/MANIFEST.MF file contains a Class-Path: attribute that
lists all the JARs of JDIC and JMF that I can found out to be needed (in
case if JDIC: jdic.jar and jdic_stub.jar, in case of JMF at least
jmf.jar plus possibly a list of currently unknown JARs).
* My Java EE Client Application JAR's META-INF/MANIFEST.MF shall
reference the "WorkaroundExtension" as a needed optional package.
* Put the Workaround.jar in JRE/lib/ext manually on each client (Thanks
god that I know all the workplaces and my application is not a public
place with thousand of anoynmous users).
Right?
This sounds like a standards compliant, vendor- and platform neutral, in
short: brilliant, solution to my problems (as long as I can find out
what JARs JMF is really installing into my system, besides jmf.jar)! You
really are an inexhaustable source of "bad" tricks. ;-)
I will try it out in the next hours and will post the results. I think
it will be interesting for other users, too.
BTW, do you have any idea whom to write to suggest putting correct
manifests into JDIC and JMF? Seems Sun lost interest in both projects,
since I just cannot find out a current email address that is not
returned by Sun's Mail Server... :-(
