title: Caught exception while loading file struts-default.xml
body: <p>I'm not that new to Java. I've done plenty of stuff with it before. But I'm migrating from PHP to Java Servlet/JSP (which I <em>am</em> new to) and I can't figure out this error to save my life. I installed Tomcat6 using Ubuntu 9.04's Synaptic Package Manager and it works like a charm. But when I put struts in my WEB-INF/lib directory and try to make a struts app, I get the below in the log file.</p>
  
  <p>I used the struts-blank.war to start the project, so the web.xml is the same as provided in struts 2.1.8.1.</p>
  
  <p>It appears that there is some issue with reading the struts-default.xml file.</p>
  
  <p>Thanks in advance</p>
