  • SOAP cannot use REST because it is a protocol, whereas REST can use SOAP web services because it can use any protocol, such as HTTP.
  • SOAP exposes business logic through a service interface, whereas REST exposes business logic through URIs.
  • JAX WS is the Java API for SOAP web services, whereas JAX-RS exposes business logic via URI.
  • SOAP defines standards that must be strictly followed, whereas REST does not define as many standards as SOAP.
  • SOAP necessitates more bandwidth and resources than REST, whereas REST necessitates less bandwidth and resources than SOAP.
  • REST web services inherit security measures from the underlying transport, whereas SOAP defines its own.
