title: 'Batik not in classpath' error when running servlet
body: <p>I'm writing an extension of the FopServlet.java included in Apache FOP. </p>
  
  <p>My platform is Linux CentOS 5.7-64bit, with Tomcat 5.5.  </p>
  
  <p>The <code>servlet</code> 'works', but I'm unable to process SVG files. </p>
  
  <p>The error I get when Tomcat runs the <code>servlet</code> is </p>
  
  <blockquote>
    <p>'Batik not in classpath'. </p>
  </blockquote>
  
  <p>But in <code>'webapps/fop/WEB-INF/lib'</code> there is <code>'batik-all-1.7.jar'</code> and all the other jars.</p>
  
  <p>I'm not a java expert, so I'm unable to focus on the problem; googling around, maybe there is a missing jar, but which one? </p>
