Which of the following methods will JAX-RS runtime automatically support if not explicitly implemented?

By default, the JAX-RS runtime will automatically support the methods HEAD and OPTIONS if not explicitly implemented. For HEAD , the runtime will invoke the implemented GET method, if present, and ignore the response entity, if set.

Which of the following is a best practice for designing a secure RESTful web service?

Q 2 – Which of the following is a best practice for designing a secure RESTful web service? A – No sensitive data in URL – Never use username, password or session token in URL , these values should be passed to Web Service via POST method.

Which of the following options of the JAX-RS API is used to create update a resource?

HTTP PUT request, used to update resource. HTTP POST request, used to create a new resource.

What mechanism does a programmer use to set up an API with JAX-RS?

Procedure

• Define the URI patterns for resources in RESTful applications.
• Define the client capabilities for RESTful applications using HTTP methods .
• Define the HTTP headers and response codes for RESTful applications using HTTP methods.

Which of the following HTTP method should be used to create resource using RESTful web service?

The HTTP POST method is used for creating a resource, GET is used to query it, PUT is used to change it, and DELETE is used to destroy it. The most common RESTful architecture involves a shared data model that is used across these four operations.

How do RESTful Web Services handle security?

You can secure your RESTful Web services using one of the following methods to support authentication, authorization, or encryption:

1. Updating the web. xml deployment descriptor to define security configuration.
2. Using the javax. ws.
3. Applying annotations to your JAX-RS classes.

How does REST API implement security?

2. Best Practices to Secure REST APIs

1. 2.1. Keep it Simple. Secure an API/System – just how secure it needs to be.
2. 2.2. Always Use HTTPS.
3. 2.3. Use Password Hash.
4. 2.4. Never expose information on URLs.
5. 2.5. Consider OAuth.
6. 2.6. Consider Adding Timestamp in Request.
7. 2.7. Input Parameter Validation.

How does RESTful web services work?

RESTful web services are built to work best on the Web. In the REST architectural style, data and functionality are considered resources and are accessed using Uniform Resource Identifiers (URIs), typically links on the Web. The resources are acted upon by using a set of simple, well-defined operations.

Is JAX-RS the same as REST API?

No, it is not. REST is an architecture style which can be implemented using servlets, but does not inherently use them, nor inherently have anything to do with Java. JAX-RS is a JSR Specification defining a Java API for RESTful Web Services. Jersey is a specific implementation of JAX-RS.

What is a @JAX-RS tutorial?

JAX-RS tutorial is provides concepts and examples of JAX-RS API. This JAX-RS tutorial is designed for beginners and professionals. There are two main implementation of JAX-RS API.

What is a JAX-RS compliant service?

RESTful service development (on Jersey) is an architecture, which inherently uses servlets. JAX-RS compliant tools like Jersey provide easy marshalling-unmarshalling of XML/JSON data, helping the developers.

What is the Java API for RESTful Web Services?

This chapter describes the REST architecture, RESTful web services, and the Java API for RESTful Web Services (JAX-RS, defined in JSR 311). Jersey, the reference implementation of JAX-RS, implements support for the annotations defined in JSR 311, making it easy for developers to build RESTful web services by using the Java programming language.
