title: Struts : How to use function:substring in <bean:write> tag
body: <p>I am using <code>Hashmap</code> to print values on jsp.</p>
  
  <p>Here is my logic:</p>
  
  <pre><code>&lt;%--
  property="collectonRoot" is my hashmap
  property="value" is my hashmap values
  --%&gt;
  
  &lt;logic:iterate id="element" name="viewServerFileCounterStatusForm" property="collectonRoot"&gt;                
              &lt;tr&gt;
                  &lt;td  class="tblrows"&gt;&lt;bean:write name="element" property="value" /&gt;
                  &lt;/td&gt;
          &lt;/tr&gt;
      &lt;/logic:iterate&gt;
  </code></pre>
  
  <p>values output are like this</p>
  
  <pre><code>/archived/2012/3/20=1
  </code></pre>
  
  <p>This is ok, but now I want to use function with map values to get string after '=' sing means '1'. How can I do this?</p>
  
  <p>thanks in advance.</p>
