I am creating my first SOAP Service and I am getting the error Not a valid Service. Could someone please help me out? I am creating a project for a imaginary belt store. SO my service is supposed to get all the products that are not shipped yet. For now i am just sending it in an array. Once the service starts working i will modify it in a better way.
Below is my error
Exception in thread "main" javax.xml.ws.WebServiceException: {http://service.itmd.iit/}OrdersImplService is not a valid service. Valid services are: {http://util.itmd.iit/}OrdersImplService

System.out.println(rs.getFetchSize());
while (rs.next()) {

String customerId = rs.getString("CUSTOMER_ID");
result[i]=orderId;
result[i]= customerId;
System.out.println("userid : " + orderId);
System.out.println("username : " + orderId);

if (conn != null) {
try {
conn.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
return result;
}
}
I created a client to call the SOAP Service. The code for the client is below
package iit.itmd.client;
import java.net.MalformedURLException;
import java.net.URL;
import javax.xml.namespace.QName;
import javax.xml.ws.Service;
import iit.itmd.domain.*;
import iit.itmd.service.Orders;
public class Client {
public static void main(String[] args) throws MalformedURLException {
URL url = new URL("http://localhost:9999/BeltStore/getnotshipped");
//1st argument service URI, refer to wsdl document above
//2nd argument is service name, refer to wsdl document above
QName qname = new QName("http://service.itmd.iit/", "OrdersImplService");
Service service = Service.create(url, qname);
Orders order = service.getPort(Orders.class);
System.out.println(order.getNotFulfilled());
}
}
Could someone please let me know what i am doing wrong? Thanks.
In your client code you specify a namespace for the service, which is good practice, but I don't see that namespace back in your service code. Your service has to define a namespace and this should correspond with the namespace your client uses for specifying the webservice method. E.g.
#WebService(targetNamespace = "http://service.itmd.iit/")

here databasesNames is null and you are doing operation on null , that is why you are getting null pointer exception

URLs are treated as encoded when received by the servlet. The % symbol followed by a 2 hex digits is the ASCII code of the character so %50 represents the letter P. To represent the % symbol you have to send %25 to represent the % symbol.
Your URL should be:
192.168.0.222:7001/Project/KonuEkle?uye=test&&baslik=%2550 discount&&mesaj=test&&kategori=123&&link=null
Here you can find a list of the character codes:

Usually you should ask a specific trouble you have instead of ask for samples. It looks like you have a structured code and all you need is implement all operations exposing as a service.
In case you need a sample, there quite a lot of resources on the web. Something like this: https://code.google.com/p/javaee6-crud-example/
I'll try give you some quick tips below:
WebService - UsuariosService.java
#POST
#Path("/usuarios")
public Response save(Usuario user) {
try {
manager= new AccessManager();
manager.save(user);
return Response.ok("User has been created.").build();
} catch (Exception e) {
e.printStackTrace();
}
return usuarios;
}
#DELETE
#Path("/usuarios/{id}")
public Response delete(#PathParam("id") String id) {
try {
manager= new AccessManager();
manager.delete(id);
return Response.ok("User has been deleted.").build();
} catch (Exception e) {
e.printStackTrace();
}
return usuarios;
}
#PUT
#Path("/usuarios/{id}")
public Response delete(#PathParam("id") String id, Usuario user) {
try {
manager= new AccessManager();
manager.update(id, user);
return Response.ok("User has been updated.").build();
} catch (Exception e) {
e.printStackTrace();
}
return usuarios;
}
If you don´t understand the usage of PUT, DELETE, POST and so on, I recommend you to read HTTP Method Tutorial. There is several discussion regarding this but you might skip it for a while.
I think you might get an idea from here. Your DAO needs to implement methods to perform CRUD interface as well. The link I've added has a very simple sample that might help as well. You might also check this JPA link.
Not sure whether info above helped but I think it is a start since you have to code it in order to understand more about it :)
I'm trying to use the #PathParam using Jersey, but it always sees it as null.
Here's the method:
The url is http://localhost:8080/GiftRegistryAPI/api/v2/inventory/david with /v2/inventory being at the class level
package com.omar.rest.inventory;
import javax.websocket.server.PathParam;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Request;
import javax.ws.rs.core.Response;
import org.codehaus.jettison.json.JSONArray;
import com.omar.rest.util.*;
#Path("/v2/inventory")
public class V2_Inventory {
#GET
#Produces(MediaType.APPLICATION_JSON)
public Response returnHostRegistries(#QueryParam("hostId") int hostId) throws Exception {
String returnString = null;
JSONArray jsonArray = new JSONArray();
try {
// A host ID of 0 indicates a null parameter, there will never be a host with an ID of 0
if (hostId == 0) {
return Response.status(400).entity("Error: please provide a valid host ID for this search").build();
}
Schema dao = new Schema();
jsonArray = dao.qryReturnHostRegistries(hostId);
returnString = jsonArray.toString();
}
catch (Exception e) {
e.printStackTrace();
return Response.status(500).entity("Server was not able to process your request").build();
}
System.out.println(returnString);
return Response.ok(returnString).build();
}
#Path("/{firstName}")
#GET
#Produces(MediaType.APPLICATION_JSON)
public Response returnSearchedRegistries(#PathParam("firstName") String name) throws Exception{
String returnString = null;
JSONArray jsonArray = new JSONArray();
System.out.println("Name: " +name);
try {
Schema dao = new Schema();
jsonArray = dao.qryReturnHostRegistries(name);
returnString = jsonArray.toString();
}
catch (Exception e) {
e.printStackTrace();
return Response.status(500).entity("Server was not able to process your request").build();
}
System.out.println(returnString);
return Response.ok(returnString).build();
}
}
The name parameter when debugged is always null, and I can't find any way at all of getting it to recognise I've entered anything in.
Any ideas what might be going wrong?
It was my import statement
import javax.websocket.server.PathParam;
should have been
import javax.ws.rs.PathParam;
In this error, most of the time the issue is wrong import. Just make sure you have import javax.ws.rs.PathParam;

Lucene uses fields to index data.
searchQuery.addTerm(**Field.CONTENT**, keywords,true);
Or
searchQuery.addTerms(new String[]{Field.TITLE,Field.DESCRIPTION,Field.CONTENT}, keywords, true)
It looks like you are searching for the exact phrase "mridul test". I think you probably want to search for "mridul" and "test". If so, give this a spin:
String[] terms = keywords.split(" ");
for(String term : terms){
searchQuery.addTerm(Field.TITLE, term,true);
}
