WebServiceSecurity applications cannot run with J2SE 5.0 for the following reasons:
J2SE 5.0 PKCS11 does not support UNWRAP mode
J2SE 5.0 PKCS11 does not support RSA/ECB/OAEPWithSHA1AndMGF1Padding with PKCS11
Use J2SE 1.4.2 with any other JCE provider (not the one included by default). Note that hardware accelerator support will not be present in this configuration.
