  2. 2. Agenda <ul><li>Restlet Concepts: </li></ul><ul><ul><li>Operations: </li></ul></ul><ul><ul><ul><li>GET, PUT, DELETE </li></ul></ul></ul><ul><ul><li>Representations: </li></ul></ul><ul><ul><ul><li>XML </li></ul></ul></ul><ul><li>Restlet-DateService: </li></ul><ul><ul><li>Download distribution </li></ul></ul><ul><ul><li>Command line usage </li></ul></ul><ul><ul><li>build.xml </li></ul></ul><ul><ul><li>The server-side code </li></ul></ul><ul><ul><li>The client-side code </li></ul></ul><ul><ul><li>JUnit tests + Jacoco </li></ul></ul><ul><ul><li>Building the jars </li></ul></ul>
  3. 3. In our last episode <ul><li>Restlet-timeservice </li></ul><ul><ul><li>Only implements GET </li></ul></ul><ul><ul><li>Data passed is simple strings </li></ul></ul><ul><ul><li>Uses only the core restlet jar file. </li></ul></ul>
  4. 4. A contact service <ul><li>Server supports addition, deletion, and retrieval of &quot;contacts&quot;. </li></ul><ul><li>Contacts are objects with the following fields: </li></ul><ul><ul><li>First Name </li></ul></ul><ul><ul><li>Last Name </li></ul></ul><ul><ul><li>Info </li></ul></ul><ul><ul><li>Unique ID </li></ul></ul><ul><li>The system represents Contacts two ways: </li></ul><ul><ul><li>As Java classes </li></ul></ul><ul><ul><li>As XML </li></ul></ul>
  5. 5. System structure <ul><li>org.hawaii.contactservice.server </li></ul><ul><ul><li>Server-specific code (in server jar file) </li></ul></ul><ul><li>org.hawaii.contactservice.client </li></ul><ul><ul><li>Client-specific code (in client jar file) </li></ul></ul><ul><li>org.hawaii.contactservice.common </li></ul><ul><ul><li>Code for both client and server (in both jars) </li></ul></ul>
  6. 6. Playing with the system <ul><li>Using jar files: </li></ul><ul><ul><li>Run server jar file in one command shell </li></ul></ul><ul><ul><li>Send/retrieve contact data using client jar file in another shell. </li></ul></ul><ul><li>Using ant commands: </li></ul><ul><ul><li>Compile, run unit tests, see coverage, build jar files. </li></ul></ul><ul><li>Using Eclipse: </li></ul><ul><ul><li>Inspect code, invoke unit tests. </li></ul></ul>
  7. 7. On to the demo.
