Consider this:

# bad style (potential name clash)
from jpype import *
startJVM('/usr/lib/jvm/java-1.5.0-sun-1.5.0.06/jre/lib/i386/client/libjvm.so','-ea')

# that's better
import jpype
jpype.startJVM('/usr/lib/jvm/java-1.5.0-sun-1.5.0.06/jre/lib/i386/client/libjvm.so','-ea')

# for long names of modules
import jpype as jp
jp.startJVM('/usr/lib/jvm/java-1.5.0-sun-1.5.0.06/jre/lib/i386/client/libjvm.so','-ea')
