The only way the launcher will work in linux is with wine, and then java being installed in wine, then using the 32 bit windows jpcsp.. even after all that Im not sure the opengl part of java will work correctly under wine.
you might want to try the native linux builds
http://buildbot.orphis.net/jpcsp/
then just type
./start-linux-x86.sh
or
java -Xmx514m -Djava.library.path=lib/linux-x86 -jar bin/jpcsp.jar
under the jpcsp directory
