    <p>I get a "java.lang.NoClassDefFoundError: com/hp/hpl/jena/shared/BadURIException" when running a very simple servlet. The error points back to the initialisation of the "Tagger" class. The code is as follows</p> <pre><code>import java.io.IOException; import java.io.PrintWriter; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import my.package.Tagger; public class NormaliserServlet extends HttpServlet{ public void doGet(HttpServletRequest req, HttpServletResponse response) throws IOException{ Tagger pot = new Tagger(""); response.setContentType("text"); PrintWriter out = response.getWriter(); out.println("hello"); out.println(pot.someMethod()); out.close(); this.log("Request for normaliser"); } } </code></pre> <p>The war file contains the jar file defining "Tagger" in WEB-INF/lib and a similar invocation works outside of a servlet. I can't seem to find what the problem would be. The web.xml is pretty standard too:</p> <pre><code>&lt;servlet&gt; &lt;servlet-name&gt;normalise&lt;/servlet-name&gt; &lt;servlet-class&gt;NormaliserServlet&lt;/servlet-class&gt; &lt;/servlet&gt; &lt;servlet-mapping&gt; &lt;servlet-name&gt;normalise&lt;/servlet-name&gt; &lt;url-pattern&gt;/normalise&lt;/url-pattern&gt; &lt;/servlet-mapping&gt; </code></pre> <p>I'm using winstone as the servlet container, but i get the exact same error in tomcat. The stacktrace is:</p> <pre><code>java.lang.NoClassDefFoundError: com/hp/hpl/jena/shared/BadURIException at NormaliserServlet.doGet(NormaliserServlet.java:13) at javax.servlet.http.HttpServlet.service(HttpServlet.java:104) at javax.servlet.http.HttpServlet.service(HttpServlet.java:45) at winstone.ServletConfiguration.execute(ServletConfiguration.java:249) at winstone.RequestDispatcher.forward(RequestDispatcher.java:335) at winstone.RequestHandlerThread.processRequest(RequestHandlerThread.java:244) at winstone.RequestHandlerThread.run(RequestHandlerThread.java:150) at java.lang.Thread.run(Thread.java:619) </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
