If you have not already practiced using Maven, be sure to follow the instructions in the Dropwizard Hello World Tutorial PDF. Note: You may need to update the dropwizard version in the pom.xml file to align with the version that you are using. To view the specific tasks you have been assigned, navigate in your Eclipse project to the Window, then Show View, then Tasks view. You can double-click on any of the tasks to be directed to the line of code where the task that needs to be completed is located. Specifically, review and complete all assigned tasks outlined below as indicated in the FIXME comments within the various Java files. A text version of this image is available: FIXME Text Version Word Document. . User Interface: Write code to create the user interface for entering data for user authentication and securing REST APIs with the proper annotation. To do this, you must complete the following tasks in the GameAuthApplication.java file based on the BasicAuth Security Example: o Register the GameUserREST Controller. . Create a JerseyClientBuilder instance named "DemoRESTClient". . Client: Write code to expose the Controller class and create a path for the client-side endpoint. To do this, you must complete the following tasks in the corresponding Java files: . GameUserRESTController.java: Add the proper annotation to expose this Controller class with the base endpoint URL as /gameusers. . RESTClientController.java: Add the proper annotation for the HTTP GET method and a path of /gameusers/ to expose an endpoint in order to return a list of all game users. . Authentication and Authorization (Server): Create a username and password-based authentication and role-based authorization for users, using annotations that set up permissions for the users. To do this, you must complete the following tasks in the corresponding Java files based on the BasicAuth Security Example: GameAuthenticator.java: Complete the Authenticator method by verifying a new instance of the GameUser class based upon the username that has been authenticated. GameAuthorizer.java: Complete the Authorizer method by roles of the user in the GameUser class based upon the username that has 22TextEdit File Edit Format t View Window Help 91% Thu 6:38 AM Q *Homework Help - Q&A from Or x D21 4-2 Assignment: Game Player | X D21 Module Four Assignment Guide X + C learn.snhu.edu/d21/le/content/1158564/viewContent/20018047/View GameAuthenticator.java: Complete the Authenticator method by verifying a new instance of the GameUser class based upon the username that has been authenticated. . GameAuthorizer.java: Complete the Authorizer method by roles of the user in the GameUser class based upon the username that has been authenticated. This completes the interface requirement for authentication using the Basic Authentication method. . User Protection and Security: Complete a REST Application including all classes, resources, and representations, along with APIs that request validation and are tested and verified using data provided. To do this, you must complete the following tasks in the GameUserRESTController.java file based on the BasicAuth Security Example: . Add the proper RolesAllowed annotation to restrict the createGameUser HTTP POST method to only authenticated users with the ADMIN role. . Add the proper RolesAllowed annotation to restrict the getGameUserByld HTTP GET method to only authenticated users with the USER role. o Test your code by running the application in Eclipse. Remember to add the values "server config.yml" as Program Arguments on the Arguments tab of Run Configuration. Use any web browser to visit the URL http://localhost:8080/gameusers. The browser's Basic Authentication dialog should appear with blank fields for Username and Password as shown below: Sign in http://localhost:8080 Username Password Sign in Cancel Valid usernames to try are "guest" "user" "player" and "admin" all with the same password value of "password" Unon successfulTextEdit File Edit Format View Window Help 91% Thu 6:38 AM Q IE . . *Homework Help - Q&A from Or X D21 4-2 Assignment: Game Player | X D21 Module Four Assignment Guide X + C learn.snhu.edu/d21/le/content/1158564/viewContent/20018047/View N Sign in http://localhost:8080 Username Password Sign in Cancel " Valid usernames to try are "guest", "user", "player", and "admin", all with the same password value of "password".

Visiting the URL with /2 will return the player whose ID is 2 (John Gruber), and so on. Close the browser, then reopen it and try accessing the same URL as a player or guest, and you should see the following JSON string displayed: { "code" : 403, "message" : "User not authorized."} .

Place them close enough to the clamp to prevent the cart from running into the pulley. Make sure the books do not interfere with the movement of the string. 19 2. Remove the rubber stopper and circular spring from the cart if attached. Use caution when removing the spring, as it can decompress quickly and become a projectile. 3. Tie a string to the cart through the hole where the rubber stopper was attached. 4. Place the cart on the table so the front edge rests against the stopping books. 5. Thread the string over the pulley and down to the floor. 10 6. Unbend a paperclip to make a hook where you can suspend the washers. See Figure 3. 7. Cut the string near the floor and tie the free end of the string to the paperclip. When the front edge of the cart rests against the books and the string is threaded over the pulley, the paperclip and the washers will be suspended just above the floor. 11 PHY 150 M4 Ne...docx Show All Xt Homework Help QEA from -:' x {.j.'
