Akshay,
So you need to add an XML digital signature to an XML document and then post that document to some external partner using pub.client:http. Is that right?
To the best of my knowledge, there are no built-in services, modules or samples that will do this for you.
You can build java services that leverage the Apache XML Security library to do this, but it is a non-trivial task.
Now, why is it that you can’t use TN?
