Hi!
I have some trouble with my application. It should be a Semantic
Annotator Assistent that receive as input a
description HTML of a Web API. To upload this description i did a RPC
and so i created two classes client-side (DataLoadingService and
DataLoadingServiceAsync) and one class server-side (named
DataLoadingServiceImpl).
When i compile i have these error:
- Rebinding com.gabrielebonzi.RSSReader.client.DataLoadingService
Checking rule <generate-with
class='com.extjs.gxt.ui.rebind.core.BeanModelGenerator'/>
Unable to find type
'com.gabrielebonzi.RSSReader.client.DataLoadingService'
Hint: Previous compiler errors may have made this type
unavailable
Hint: Check the inheritance chain from your module; it may
not be inheriting a required module or a module may not be adding
its source path entries properly
- Deferred binding failed for
'com.gabrielebonzi.RSSReader.client.DataLoadingService'; expect
subsequent failures
Unable to load module entry point class
com.gabrielebonzi.RSSReader.client.RSSReader (see associated exception
for details)
java.lang.RuntimeException: Deferred binding failed for
'com.gabrielebonzi.RSSReader.client.DataLoadingService' (did you
forget to inherit a required module?)

This is the code:
CLIENT-SIDE
1) DataLoadingService
package com.gabrielebonzi.RSSReader.client;
import com.google.gwt.user.client.rpc.RemoteService;
import com.google.gwt.user.client.rpc.RemoteServiceRelativePath;
@RemoteServiceRelativePath("dataloading")
public interface DataLoadingService extends RemoteService
{
Doc dataLoading(String path);
}
2) DataLoadingServiceAync
package com.gabrielebonzi.RSSReader.client;
import com.google.gwt.user.client.rpc.AsyncCallback;
import com.google.gwt.xml.client.Document;
public interface DataLoadingServiceAsync
{
void dataLoading(String path, AsyncCallback<Doc> callback);
}
SERVER-SIDE
3) DataLoadingServiceImpl
package com.gabrielebonzi.RSSReader.server;
import java.io.IOException;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import org.xml.sax.SAXException;
import com.gabrielebonzi.RSSReader.client.DataLoadingService;
import com.gabrielebonzi.RSSReader.client.Doc;
import com.google.gwt.dom.client.Element;
import com.google.gwt.user.server.rpc.RemoteServiceServlet;
import com.google.gwt.xml.client.Document;
public class DataLoadingServiceImpl extends RemoteServiceServlet
implements DataLoadingService
{
private static final long serialVersionUID = 1L;
Doc doc;
public Doc dataLoading(String path)
{
DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
DocumentBuilder builder = null;
try
{
builder = factory.newDocumentBuilder();
}
catch (ParserConfigurationException e)
{
e.printStackTrace();
}
try
{
doc = (Doc) builder.parse(path);
}
catch (SAXException e)
{
e.printStackTrace();
}
catch (IOException e)
{
e.printStackTrace();
}
Element root = (Element) doc.getDocumentElement();
System.out.println("Stampa nodo radice albero xml:
"+root.getNodeName());
return doc;
}
}
And i use these methods to call the created classes:
public void goURL(String path) throws RequestException, IOException
{
setPath(path);
String url = URL.encode(path);
dataSvc = GWT.create(DataLoadingService.class);
dataSvc.dataLoading(path, callback);
ServiceDefTarget endpoint = (ServiceDefTarget) dataSvc;
endpoint.setServiceEntryPoint(GWT.getModuleBaseURL() +
"dataloading");
//System.out.println("Testo: "+doc doc.get.getTextContent());
//htmlItem.addText(doc.getTextContent());
layout();
Window.confirm("Hai inserito '"+path+"'. E' corretto?");
}
AsyncCallback <Doc> callback = new AsyncCallback<Doc>()
{
public void onFailure(Throwable caught)
{
System.out.println("Failed: "+caught.getMessage());
}
public void onSuccess(Doc result)
{
// htmlItem.addText(result.get);
System.out.println("OK! Entraton in onSuccess!");
}
};
