title: Java Webapplication works from netbeans but not in "stand-alone"
body: <p>i've created a rather simple Web application for demo purposes. It works perfectly fine when running it from netbeans (using tomcat). there is a search form and a search results display page. The search result display page uses AJAX with JQuery and it datatables plugin. a column in the datatable contains a dynamically generated image.</p>
  
  <p>When i deployed it statically in tomcat applications works and no errors are thrown but the images are not created. the column displays the content of the image tags alt attribute.</p>
  
  <p>How could I "debug" this issue? Is it a tomcat config problem?</p>
  
  <p>EDIT:</p>
  
  <p>I can render image by going to the render servlet directly i then get following message displayed instead of the image:</p>
  
  <pre><code>The image cannot be displayed because it contains errors
  </code></pre>
  
  <p>This is on Windows. The images are created from an existing library that does the work. This works perfectly fine when deploying the application from netbeans. Also note I'm not a tomcat expert.</p>
