[JAVA] Web Service con axis2
Salve a tutti, sto iniziando a studiare come creare dei web service con axis2 ma mi sto imbattendo in alcuni problemi.
Ho creato la classe che definisce le operazioni rese disponibili dal web service, la classe è la seguente: Codice:
package samples.quickstart.service.pojo;
import samples.quickstart.service.pojo.Util.Prodotto;
import java.util.*;
public class StockQuoteService {
private HashMap map = new HashMap ();
public double getPrice(String symbol){
Double price = (Double) map.get(symbol);
if(price!=null)
return price.doubleValue();
return 42.0;
}
public void update(String symbol, double price){
map.put(symbol, new Double(price));
}
public Prodotto[] getCatalogo(){
Prodotto[] catalogo = new Prodotto[map.size()];
Set chiavi = map.keySet();
Iterator it = chiavi.iterator();
for(int i=0; i< chiavi.size(); i++){
String key=(String)it.next();
catalogo[i]= new Prodotto(key, ((Double) map.get(key)).doubleValue());
}
return catalogo;
}
}
Detto ciò ho generato il pacchetto aar da installare su tomcat (tramite il tool di eclipse "Axis2 service archive") ed ho installato il web service ottenendo questo file wsdl: Codice:

Quando invece provo ad invocare getCatalogo come risposta dal web service ottengo null. Di seguito incollo il client che ho scritto con l'output che mi viene dato: Codice:
import java.rmi.RemoteException;
import org.apache.axis2.AxisFault;
import test.ws.client.StockQuoteServiceStub;
import test.ws.client.StockQuoteServiceStub.GetPrice;
import test.ws.client.StockQuoteServiceStub.GetPriceResponse;
import test.ws.client.StockQuoteServiceStub.GetCatalogoResponse;
import test.ws.client.StockQuoteServiceStub.Prodotto;
import test.ws.client.StockQuoteServiceStub.Update;
public class X {
private StockQuoteServiceStub sqss;
public X() throws AxisFault {
sqss = new StockQuoteServiceStub();
}
public static void main(String[] args) throws RemoteException {
X classe = new X();
classe.update("fiat", 50.0);
classe.update("opel", 72.2);
classe.update("mercedes", 100);
System.out.println(classe.getPriceW("fiat"));
System.out.println(classe.getPriceW("mercedes"));
System.out.println(classe.getPriceW("skoda"));
System.out.println(classe.getPriceW("opel"));
Prodotto[] ps = classe.getCatalogo();
for(int i=0; i<ps.length; i++)
System.out.println("Catalogo"+ps[i].getNome()+", "+ps[i].getPrezzo());
}
public double getPriceW(String nome) throws RemoteException{
GetPrice parametro = new GetPrice();
parametro.setSymbol(nome);
GetPriceResponse grp = sqss.getPrice(parametro);
return grp.get_return();
}
public void update(String nome, double prezzo) throws RemoteException{
Update imp = new Update();
imp.setSymbol(nome);
imp.setPrice(prezzo);
sqss.update(imp);
}
public Prodotto[] getCatalogo() throws RemoteException{
GetCatalogoResponse risposta = sqss.getCatalogo();
Prodotto[] catalogo = risposta.get_return();
return catalogo;
}
}

Perchè un comportamento simile? Cosa sbaglio? Un'ultima cosa, per generare le classi stub ho installato anche il plug-in per eclipse di axis2 (Axis2 code generator), ma questo tool a quanto ho potuto notare non mi funziona mai e non mi da mai nessun file in output mi da un messaggio d'errore: Quote:
Grazie a tutti. Ciao ciao |
