============================================================================

Cause

This is cause due to incorrect path in for the of Keystore for Signature token under Security tab of Web Service step.

Environment

Release : 10.2

Component : CA Service Virtualization

Resolution

First copy the keystore file to an accessible location in Simulator machine.
Then change the path of Keystore for Signature token under Security tab to make sure it points to that location of simulator machine.
This will resolve the "Unable to instantiate Crypto class; nullpointer exception" exception.

Additional Information

After this error is resolved, if you get connection timeout error, make sure that the endpoint host is accessible from the Simulator machine on that port using Telnet command in Simulator machine.
