Hi
This simple Servlet works (address: http://localhost:8080/testapp/testservlet):
public class Server extends HttpServlet {
public void doGet (HttpServletRequest req, HttpServletResponse res) throws
ServletException, IOException {
PrintWriter out = res.getWriter();
out.println("Hello, you!");
out.close();
}
}
I'm using an ant script that creates testapp.war and deploys it.
my web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd";
version="2.4">
<servlet>
<servlet-name>TestServlet</servlet-name>
<servlet-class>testpackage.TestServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>TestServlet</servlet-name>
<url-pattern>/testservlet</url-pattern>
</servlet-mapping>
</web-app>
However, my simple Xml Rpc application doesn't. If my client makes a Xml Rpc
call on address http://localhost:8080/testapp/testservlet, I get the error:
Exception in thread "main" java.io.IOException: Server returned HTTP response
code: 500 for URL: http://localhost:8080/testapp/testservlet
Code:
public class Server extends HttpServlet {
public void doPost (HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
XmlRpcServer xmlrpc = new XmlRpcServer();
xmlrpc.addHandler ("testHandler", new TestHandler());
byte[] result = xmlrpc.execute(req.getInputStream());
res.setContentType("text/xml");
res.setContentLength(result.length);
OutputStream out = res.getOutputStream();
out.write (result);
out.flush ();
}
}
public class TestClient {
public static void main(String[] args) throws XmlRpcException,
IOException {
XmlRpcClient xmlrpc = new XmlRpcClient
("http://localhost:8080/testapp/testservlet";);
Vector params = new Vector ();
params.addElement ("hello world");
// this method returns a string
String result = (String)
xmlrpc.execute("testHandler.hello", params);
System.out.println(result);
}
}
public class TestHandler implements Serializable {
public String hello(String input) {
return input;
}
}
