title: Java JSON package importing failure
body: <p>I'm working with OpenJDK 7 (openjdk-7-jdk) under Ubuntu,
  compiling my code with following command</p>
  
  <pre><code>javac -d ./classes ./src/Program.java
  </code></pre>
  
  <p>My code contains imports</p>
  
  <pre><code>...
  import java.util.concurrent.ExecutorService;
  import javax.json.Json;
  import javax.json.stream.JsonParser;
  import javax.swing.text.html.parser.ParserDelegator;
  ...
  </code></pre>
  
  <p>and i'm getting the following error</p>
  
  <pre><code>./src/Program.java:21: error: package javax.json does not exist
  import javax.json.Json;
                   ^
  ./src/Program.java:22: error: package javax.json.stream does not exist
  import javax.json.stream.JsonParser;
                          ^
  </code></pre>
  
  <p>It is curious that there is no problems with importing from javax.swing or java.util.</p>
  
  <p>Please tell, what am i doing wrong?</p>
