    <p>I'm trying to make a Java servlet that can make Apache Thrift calls, but I'm having trouble starting the servlet.</p> <p>I have a <strong>thrift client</strong>, a Java class for making calls to the thrift server</p> <pre><code>public class ThriftClient { static TTransport transport; static TProtocol protocol; static MyService.Client client; static long xtk_pointer; public static void openSocket() throws TException { transport = new TSocket("localhost", 9090); transport.open(); protocol = new TBinaryProtocol(transport); client = new MyService.Client(protocol); } </code></pre> <p>and I have a <strong>java servlet</strong> which opens a socket through the thrift client</p> <pre><code>public class MyServlet extends HttpServlet { protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { out.println("Hello World"); } void startThrift(String [] args) { try { ThriftClient.openSocket(); </code></pre> <p>However, when I try to run this servlet (using eclipse and a tomcat server), I get an error like </p> <pre><code>SEVERE: A child container failed during start </code></pre> <p>and a <code>ClassNotFoundException</code> for <code>org.apache.thrift.TException</code></p> <p><strong>EDIT: All I had to do was include the thrift jars into the Tomcat Server's classpath. See my answer below</strong></p> <p>I have used the thrift client already without any ClassNotFoundExceptions, and the servlet works on its own as well. However, once I add <code>ThriftClient.openSocket();</code> into the servlet, it breaks, so I have a feeling Thrift and Tomcat are clashing somehow. Any ideas?</p> <p>Edit: The weird part is that I never call the method <code>startThrift()</code> but I still get the error.</p>

    3. COYou can call `exception.printStackTrace()` inside the catch block and you should see the stack trace in the Eclipse console.

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.
