Abstract: A method, computer program product, and system for auto generating a Java application programming interface (JAX-RS) for representational state transfer (REST) web services. A reference interface for a REST service object is received by a server computer system. A set of determiners defines a plurality of configuration values for a REST service object to generate a service binding. A plurality of resource methods for each resource class in the reference interface is determined, and for each resource method, a parameter, a return type, and an exception are determined. Each resource method of each class is sequentially processed and the name of each resource is written into a string buffer. The operation type for each resource method for each resource class is determined based on at least one predefined match and an operation name is written into the string buffer for each resource method. A return type is determined for each resource method for each resource class.
