So i'm working through this and have it about 50% done and i'm running =20=

into trouble, i'm not much of a Java person so maybe someone on this =20
list might be able to shed some light on the subject. I've got the =20
bindings to compile, jar to build, libpreludejava.so to link and load =20=

and when I get call:


c=3D new ClientEasy("prelude-java-agent");
c.Start();

I get:

$ java test
java.io.IOException: Error importing X509 private key: ASN1 parser: =20
Error in DER parsing.
java.io.IOException: Error importing X509 private key: ASN1 parser: =20
Error in DER parsing.
    at java.lang.reflect.Constructor.newInstance(libgcj.so.90)
    at com.prelude.easy.Client.Start(Client.java:45)
    at test.main(test.java:13)


I can verify that the profile "prelude-java-agent" works using the =20
gnutls-cli tool, and can also very that the custom python script's =20
i've built around this work too. Tracing through the various =20
libraries, the only thing I can think of is that the JNI (jvm) is =20
getting tripped up somewhere trying to actually read the key...

I'm attaching a patch of what i've come up with so far, thinking while =20=

i bang my head against the wall trying to debug this, maybe someone =20
with some more java I/O exp. could take a look at it and see why the =20
asn1/gnutls init is failing. I've traced it down to the auth_init =20
function in the code (tls-auth.c +350 or so)


I've created an "issue" with the code attached to it so we can keep =20
easy track of this:
