javax.crypto

Hello list

I use a --disable-shared GCJ, built two days ago (revision 117030)...

What's the state of javax.crypto? Gnu classpath states that they 
implemented it mostly. But when running a compiled test app (attached), 
I get:

WARNING: Error loading security provider gnu.javax.crypto.jce.GnuCrypto: 
java.lang.ClassNotFoundException: gnu.javax.crypto.jce.GnuCrypto
WARNING: Error loading security provider gnu.javax.crypto.jce.GnuSasl:

PBEWithMD5AndDES
   at javax.crypto.SecretKeyFactory.getInstance(bin)
   at CryptionUtilities.crypt(bin)
   at CryptionUtilities.main(bin)

Do I miss some requirements? I didn't find anything on the net...


thanks
Marco
