RESTful Web Services with Java in less than a month!

Explore the application class for deploying a restful service, comparing manual resource registration and package scanning, and using singletons to maintain state across requests.

Implement a custom message body writer for hash map data, create a wrapper with an ex-MIL root element, and register it in the application to enable ex-MIL responses.

Create a new message body reader to parse a hash map of integer car IDs to cars, enabling the rest endpoint to add multiple cars at once across formats.

Implement a ParamConverterProvider to transform form-encoded dates into local time and back, register it manually in a rest app, and ensure seamless string-to-local time conversion.

Learn how to implement an XMLAdapter and use package annotations to marshal local time for json and xml responses, register the adapter, and handle map types in RESTful Java services.

Learn how a container response filter implements cors by adding access-control headers to responses, enabling secure cross-origin resource sharing for rest endpoints.

Implement a container request filter that assigns application/json as the default accept header when it is missing, using the request context and registering the filter.

Develop a general message data transfer object and an exception mapper to return a user-friendly 406 not acceptable response for unsupported media types.

Explore using the query param annotation to pass overnight as a URL parameter for car resources, enabling overnight state, pagination, and dynamic request handling in a RESTful Java API.

Learn to implement a global case-insensitive query parameter filter in a Java REST app by abstracting the logic into a reusable container request filter, applied globally with a binding annotation.

Explore the priority annotation to order filters and interceptors for Jack Sarus endpoints, using authentication and user constants to control processing order, defaulting to 5000 when unset.

Explore securing car creation in a rest java service by implementing a car creation constraint filter that validates a specific header with a name-binding annotation at method level.

Implement basic authentication with a JAAS-based JDBC realm in GlassFish by creating a two-table user and role database, hashing passwords with SHA-256, and configuring the realm in the server.

Configure basic authentication by creating a persistence unit and data source, and define security constraints and role mappings in the deployment descriptor, then test the connection.

Configure basic authentication for rest resources by mapping the admin role in the deployment descriptor, enabling authentication constraints, and testing with a base64 encoded username:password in the authorization header.

Developers can now create restful webservices with Java, building a solid ground layer to become a capable API developer and evangelist.

Download and install GlassFish server 5 by decompressing the archive to a fixed location. Use NetBeans to add an app server, select domain and ports, and preserve session across redeployment.
