extrahiert werden. Nun habe ich einen erholsamen Webservice mit einer get-Methode erstellt, die eine Liste von Banktransaktionen basierend auf einer Konto-ID zurückgibt. Der Service funktioniert gut, wenn ich es teste.javax.ws.rs.NotFoundException: Der Parameter konnte nicht aus der HTTP-Anforderung
Dann habe ich einen erholsamen Client in meinem managedBean erstellt. Diese Ausnahmen erscheinen, wenn ich meinen Webservice aufruft.
Ich habe diese Methode bereits mit einer Liste aller Clients (ohne Parameter) versucht und es funktionierte, aber wenn ich einen Parameter zu meiner Transaktionsmethode hinzufüge, konnte die ID nicht aus meiner Anfrage extrahiert werden.
das ist mein WebService

@EJB

public List<Transaction> getTransactionById(@PathParam(value="id") Integer id)
{
Account account=local1.findAccountByid(id);
return local2.showTransactionByAccount(account);

PS: Ich denke, diese Zeile das Problem ist seit Es erhält die Basis-URL, aber die ID wird nicht korrekt extrahiert webtarget=client.target(base_url).path("id");
Wenn Sie noch etwas brauchen, lassen Sie es mich bitte wissen.
danke :) Sie sind richtig, Herr, ich tat das und ich fügte auch eine Zeile in meinem Client, dass ich wegen der Stress vergessen lol. Ich werde die Antwort posten. – javaManiac
Ja, tatsächlich funktioniert das WebTarget-Objekt wie ein Builder, und Sie müssen es mit dem Neuabstimmungswert einer beliebigen Methode neu zuweisen. – ChapL
