Re: XMLSignature.sign() NullPointerException

Hi Sean,


I am also facing this problem.

I have also explicitly specify the provider like this:-

signContext.setProperty
     ("org.jcp.xml.dsig.internal.dom.SignatureProvider", new
au.com.eracom.crypto.provider.slot0.ERACOMProvider());


but i am still getting the error.

can you please provide your input.
