In WSS4J I use the follwing way to define the provider to XML-SEC:
JCEMapper.setProviderId(id)
This static method sets the Id to use for SIgnature etc. For
XMLCipher you must use different methods, look at that:
if (provider == null) {
xmlCipher = XMLCipher.getInstance(symEncAlgo);
}
else {
xmlCipher = XMLCipher.getProviderInstance(symEncAlgo, provider);
}
If you like to specify a provider for XMLCipher you have
to use a specific getInstance method - see above. The provider
in this case is the provider id string, e.g. "BC" for
BouncyCastle.
