Java interoperability

[Paul-417]

I need to decrypt a string encrypted by an external company in java as
follows using our public key -

Cipher cipher = Cipher.getInstance( "RSA/ECB/PKCS1Padding", "BC");

How would I decrypt the resulting message using our private key in
Crypto++?

I have tried using RSAES_PKCS1v15_Decryptor  which doesn't work,
presumably because I am missing the ECB part?

If the RSA/ECB/PKCS1 combination cannot be dealt with, is there an
alternative java combination I can suggest (RSA/ECB/NoPadding?) and
what would the equivalent Crypto++ Decryptor look like?.

I got this working by changing the java end to use RSA/NONE/
PKCS1Padding.
This works with the RSAES_PKCS1v15_Decryptor
