Hi Michael,

The Java signature method for the method we are calling is:

encrypt(string, string, string, string)

which is declared as the following in the iPGP java class:

public native int encrypt(String passphraseoruid, String datain, String
pgpkeyring, String outputfilename);

Regards,

Well, this is what it says:

Trying method encrypt: name matches
Method is not static
Method has 4 arguments; expecting 3

And you haven't showed us the Java method signature, so I can't advise
any
further.
