title: Java Bean: how <jsp:setProperty> in <jsp:useBean> is generated into Java Code
body: <p>For example, I have this code:</p>
  
  <pre><code>&lt;jsp:useBean id="dog" class="Dog" scope="application"&gt;
       &lt;jsp:setProperty name="dog" property="breed" value="House Dog !!!"/&gt;
  &lt;/jsp:useBean&gt;
  </code></pre>
  
  <p>I know how it works. But, sometimes, I change some some code in this, for example: "dog" to "newDog", I will meet error or unguested-result (with me).</p>
  
  <p>Please give me how above code is generated into Java. (maybe just a main idea)</p>
  
  <p>Thanks :)</p>
