as you can imagine i tried a lot of hacks and workarounds to get a stand=

on the wiki page. but now i try to generate a simple keystore and get th=

org.bouncycastle.jce.provider.JDKPKCS12KeyStore.engineStore( JDKPKCS12Key=

at java.security.KeyStore.store(KeyStore.java:620)
...
for me it looks like cant load class or invalid protection domain. playi=
ng =
with classloader up and down, xbootclasspath or =
-Dosgi.parentClassloader=3Dapp dont change anything. i tried some change=

java.policy like permission grand all. but nothing changes.
maybe somebody has solved the same problem within his app or has a good =

is a (all threads the same Classloader) switch. maybe there is a =
combination of problems. security and classloading. i dont realy =
understand how this security stuff exactly works. i know how the =
classloaders chained together, but not how the protection domains can be=

modified on them.
iam grateful for any tip about debuging or hopefully solving this proble=

thanx for the fast and helpful hints:-)

hi chris,
thats the classloader try/catch thing i have tested. think i have to cut=
=
all the stuff out and test only the keystore alone. maybe i have to much=
=
of this setcurrentClassloader lines in my app.i used it for all the =
factory stuff from xerces but iam not sure how much colateral damage it =
=
cause:-) is it posible to setup this stuff once in the "main" method and=
=
it works for all threads. or do you use that localy, like catching the =
factory creation and thats it?
feel free to collect some more ideas here. dont want to write swing apps=
=
anymore:-)
