Hey, ive got a problem and im searching for hours to find a solution. My problem is the following:
I have a little RPC-Service which returns as a result a "Domain"- Object (Own custom-class). But this Domain-Object could not be serialized, though i have made this "Domain"-class serializable with com.google.gwt.user.client.rpc.IsSerializable. Im using GWT SDK 2.01 and getting the following compiling error: [ERROR] com.google.gwt.core.client.JavaScriptObject is not assignable to 'com.google.gwt.user.client.rpc.IsSerializable' or 'java.io.Serializable' nor does it have a custom field serializer (reached via com.vostokdomains.kis.client.objetcs.Domain) [ERROR] com.google.gwt.core.client.JavaScriptObject has no available instantiable subtypes. (reached via com.vostokdomains.kis.client.objetcs.Domain) I hope you can help me out!! -------------------------------------------- Enclosed some code-snippets: package com.vostokdomains.kis.client.objetcs; import java.util.Date; import com.google.gwt.i18n.client.DateTimeFormat; import com.google.gwt.user.client.rpc.IsSerializable; ========== Domain-Object============ public class Domain implements Comparable<Domain>, IsSerializable{ private String adresse; private String tld; private Date create; private Date next; private int laufzeit; private double preis; private Kontakt registrar; private Kontakt admin; private Kontakt tech; private Kontakt owner; private String namesever1; private String nameserver2; private String records; Domain(){ } public Domain(String adresse, String tld, int tag, int monat, int jahr, Kontakt kontakt) { DateTimeFormat fmt = DateTimeFormat.getFormat("dd.MM.yyy"); this.setRegistrar(new Kontakt("Keine Angabe")); this.adresse=adresse; this.tld=tld; this.owner=kontakt; this.next=fmt.parse((tag+"."+monat+"."+jahr)); return; } public Domain(String adresse, String tld, Kontakt kontakt){ this.setRegistrar(new Kontakt("Keine Angabe")); this.adresse=adresse; this.tld=tld; this.owner=kontakt; this.next=new Date(); } [....] ================= DatabaseService ==================== public class DatabaseServiceImpl extends RemoteServiceServlet implements DatabaseService { /** * */ private static final long serialVersionUID = 1L; public Domain getDomains() { DBConnection conn = new DBConnection(); conn.connect(); Connection dbconn = conn.getConnection(); System.out.print("TEST"); Domain d = null; try { ResultSet rs = null; Statement stm = dbconn.createStatement(); System.out.print("STATEMENT"); stm.execute("SELECT * FROM domains"); rs = stm.getResultSet(); rs.next() ; Kontakt k = new Kontakt(rs.getString(2)); d = new Domain(rs.getString(3), "tld", k); } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } return d; } } ======================== RPC Call ======================== public class Kis implements EntryPoint { @Override public void onModuleLoad() { DatabaseServiceAsync rpc; rpc = (DatabaseServiceAsync) GWT.create(DatabaseService.class); ServiceDefTarget target = (ServiceDefTarget) rpc; String moduleRelativeURL = GWT.getModuleBaseURL() + "DatabaseServiceImpl"; target.setServiceEntryPoint(moduleRelativeURL); /* test.add(); RootPanel.get().add(test.vpanel);*/ rpc.getDomains(new AsyncCallback<Domain>() { public void onFailure(Throwable caught) { Window.alert("Übertragung fehlgeschlagen!" ); } public void onSuccess(Domain rs) { //Expiration ex = new Expiration(); //ex.create(rs,0); System.out.print(rs.getAdresse()); //RootPanel.get().add(ex.vpanel); } } ); } } -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
