Re: Class is not a servlet

Seriously, David's recommendation is the way forwards.

When he said, 'read the spec', he was indicating that you should at least have a basic familiarity with what a Servlet is. There are *extensive* and complete tutorials from basic to advanced to found for free online. Search Google (other search engines are available). Clue: Servlets are not written like a bean Class, you do not use the main(...) method.

Thank you very much for the two answers.

I don't know Java servlet enough to make PartsXupdate work
but now I have a way to follow.

I highly recommend reading the servlet spec.  There you will see a
servlet extends HttpServlet and overrides one or more of it's methods.

Now that I've changed the class file,
and re-do the deployment, Tomcat first show me
HTTP Status 405 - HTTP method POST is not supported by this URL
than I modify PartsXupdate.java as below
and only work the out.println

import org.xmldb.api.base.*;
import org.xmldb.api.modules.*;
import org.xmldb.api.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;

public class PartsXupdate extends HttpServlet {


throws ServletException, IOException {

PrintWriter out = response.getWriter();
out.println("Commento Inserito");
}


  public static void main(String[] args) throws Exception {
     Collection col = null;
     try {
        String driver = "org.apache.xindice.client.xmldb.DatabaseImpl";
        Class c = Class.forName(driver);

        Database database = (Database) c.newInstance();
        DatabaseManager.registerDatabase(database);

public void doPost(HttpServletRequest request, HttpServletResponse response) col = DatabaseManager.getCollection("xmldb:xindice://localhost:8080/db/test"); String xupd = "<xupdate:modifications version=\"1.0\" xmlns:xupdate=\"http://www.xmldb.org/xupdate\";>" +

"<xupdate:insert-after select=\"/scheda/info\">"  +
"<xupdate:element name=\"commento\">Bel libro!</xupdate:element>"  +
"</xupdate:insert-after>"  +
"</xupdate:modifications>";



   String nome = "4.xml";

           /* We are using XUpdateQueryService */
           XUpdateQueryService service =


           service.updateResource(nome, xupd);
     }
     catch (XMLDBException e) {
        System.err.println("XML:DB Exception occurred " + e.errorCode);
     }
     finally {
         if (col != null) { col.close();}
     }
  }
}

(XUpdateQueryService) col.getService("XUpdateQueryService", "1.0");
