Hi,
Jersey 1.x supports HMAC_SHA1 for OAuth 1. This exception occurs if the class with name "HMAC_SHA1” cannot be found using META-INF/services lookup. Do you have the jar "oauth-signature-*.jar” on the classpath? Which jersey version do you use?
Can you also try to use different signature method (e.g. PLAINTEXT)?
