find and call web service from uddi java

So I have been looking around for days and I still can't find a simple working method. This is what I am trying to do:
1 - Search and find web services registered in UDDI based on keywords
2 - Decide which service fits and use/call it
All this using Java (Eclipse).
I don't want to create my own uddi nor do I want to publish services, just find existing services stored in the public UDDI (I believe there's one, right?). I thought that these two tasks (find WS, call WS) would be easy and that it would be possible to find sample code to use, but I can't find any.
I came across Juddi while searching, but not sure if it works for my case and if it's worth installing.
Any tutorials? suggestions ? I found the following code, but can't find the jar file to use its libraries:

GWT Java how to convert List<File> to something the client side can use?

EDITED
This is probably a stupid question but I can't figure it out. I am using Java with GWT in Eclipse to create a RPC application to get google drive metadata. All is working (I am getting back the metadata on the server side) but I can't figure out how to pass this data over to the client side so that I can display it.
I am getting a list of metadata for google drive docs as follows:
public List<File> getFromRemoteServer()
throws HowToListingException {
List<File> lista = null;
try {
lista = retrieveAllFiles(getDriveService("email#xxxx.org"));
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (GeneralSecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (URISyntaxException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return lista;
}
My question is, how do I change the List type to something that the client side can use? i.e what do I put here (fill in the blank)? And how would I convert lista to that type?
asyncSvc.getFromRemoteServer( {
new AsyncCallback<____________>() {
}
A bit more hopefully clarifying information:
I know to make this work I have to serialize the File object. I'm just not sure if I can or where to put this.
http://www.gwtproject.org/doc/latest/tutorial/RPC.html#serialize
In the server side implementation, I am using this File:
import com.google.api.services.drive.model.File;
Which I need to use to have this code work properly:
public static Drive getDriveService(String userEmail) throws GeneralSecurityException,
IOException, URISyntaxException {
HttpTransport httpTransport = new NetHttpTransport();
JacksonFactory jsonFactory = new JacksonFactory();
GoogleCredential credential = new GoogleCredential.Builder()
.setTransport(httpTransport)
.setJsonFactory(jsonFactory)
.setServiceAccountId(SERVICE_ACCOUNT_EMAIL)
.setServiceAccountScopes(Arrays.asList(DriveScopes.DRIVE))
.setServiceAccountUser(userEmail)
.setServiceAccountPrivateKeyFromP12File(
new java.io.File(SERVICE_ACCOUNT_PKCS12_FILE_PATH))
.build();
Drive service = new Drive.Builder(httpTransport, jsonFactory, null)
.setHttpRequestInitializer(credential).build();
return service;
}
private static List<File> retrieveAllFiles(Drive service) throws IOException {
List<File> result = new ArrayList<File>();
Files.List request = null;
try {
request = service.files().list();
FileList files = request.setQ("'"+"0B9lpwZZfxxxxxxxxVeEJFR3M"+"' in parents and trashed=false").execute();
result.addAll(files.getItems());
request.setPageToken(files.getNextPageToken());
}
catch (IOException e)
{
System.out.println("An error occurred: " + e);
request.setPageToken(null);
}
for(File f:result)
{
System.out.println(f.getTitle());
System.out.println(f.getOwners());
System.out.println(f.getModifiedDate());
}
return result;
}
The problem comes when I try to use
import com.google.api.services.drive.model.File;
on the client side in the synchronous and asynchronous interfaces and the client code (entry point). I get the error message about "did you forget to inherit a required module - no code found for this import." I am assuming that means I can't use this on the client side. I've tried to import java.io.File instead but then I get messages that I can't convert between the two types.
I feel like I am close, I just need a push in the right direction. Any help appreciated.

You can only pass classes that implement Serializable. I don't know what File class is, but if it's not serializable, you cannot pass it using RPC.
If File implements Serializable, you can pass ArrayList<File> to AsyncCallback. Note that with GWT it is always better to use a specific implementation (ArrayList instead of List) in order to reduce the compiled code.

Design your own class that contains the info you need to display. And maybe a unique path. Send that class, which should be Serializable to the client.

Google App Engine HTTP ERROR 503 error

Ï am Taking data From server written in "C" using Sockets .
My java class name is ReceivingData, and here's the code for receiving the data and storing it in ArrayList and passing the ArrayList to other Class's Constructor.
package pack.exp;
import java.io.InputStream;
import java.net.Socket;
import java.util.ArrayList;
import java.util.List;
public class ReceivingData implements Runnable
{
public static void main(String[] args)
{
Thread t = new Thread(new ReceivingData());
t.start();
}
public List<String> obj1;
#Override
public void run()
{
Socket s;
InputStream stream;
try
{
s = new Socket("10.9.211.22", 6870);
stream = s.getInputStream();
byte[] data = new byte[13];
int read;
String can_Id= null;
while((read = stream.read(data)) != -1)
{
String can_Data=
String.format("%02X:%02X:%02X:%02X,
data[0], data[1], data[2], data[3]);
List<String> obj1= new ArrayList<String>();
obj1.add(can_Data.substring(0, 2));
obj1.add(can_Data.substring(3, 5));
obj1.add(can_Data.substring(6, 8));
obj1.add(can_Data.substring(9, 11));
Receiving_At_Regular_IntervalServlet rari= new
Receiving_At_Regular_IntervalServlet(obj1);
Thread.sleep(3000);
}
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
This is the Servlet which is receiving the data from ArrayList passed by the above File.
and storing this data from the arraylist in to the Entity for datastore and deploys it on the Google App engine.
package pack.exp;
#SuppressWarnings("serial")
public class Receiving_At_Regular_IntervalServlet extends HttpServlet
{
List<String> obj2= new ArrayList<String>();
public Receiving_At_Regular_IntervalServlet(List<String> obj2) throws
IOException
{
this.obj2= obj2;
System.out.println("Receiving in Web Project" + obj2);
System.out.println("");
System.out.println("");
}
public void doGet(HttpServletRequest req, HttpServletResponse resp) throws
IOException
{
Key k1 = KeyFactory.createKey("C","0D F0 0800 1");
String parameter1 = obj2.get(0);
Entity can1 = new Entity(k1);
can1.setProperty("First Parameter", parameter1);
DatastoreService datastore = DatastoreServiceFactory.getDatastoreService();
datastore.put(can1);
Entity can11 = null;
try
{
can11= datastore.get(k1);
}
catch (EntityNotFoundException e)
{
e.printStackTrace();
}
String first_P= (String) can11.getProperty("First Parameter");
resp.setContentType("text/plain");
resp.getWriter().println("Parameter--- " + first_P);
}
}

The ReceivingData code evidently runs a thread and reads data from 10.9.211.22 port 6870 using Socket from a local computer. That's fine. It converts four bytes to a List and passes that to Receiving_At_Regular_IntervalServlet. Fine but not what you need.
This part might work on a development computer but won't work if deployed to the cloud. AppEngine servers does not permit developers to define main(), use Socket or communicate with private IP subnet 10. Forget about deploying that code to AppEngine.
Receiving_At_Regular_IntervalServlet has a custom constructor. AppEngine does not call your constructor because its servlet code expects only the default constructor. That is probably when your 503 error occurs.
With servlets the data is not supposed to come in via a constructor. Data must come in via members of the request parameter of the doGet method (though to be RESTful you should rather use doPut in this example). You insert the data into the request parameter but sending a correctly constructed http request to the server. Your code lacks that web application design.
Build your main program and your AppEngine code in separate projects and make main talk to servlet using http.

HTTP ERROR 503 error
You can't help anything when a server throws this error. It is only thrown when a service from the server is unavailable.
You need explicit handling on such error codes, other than 200 OK, in the client app and appropriate message has to be shown or as the alternate requirement suggestion.

how to use Service,ServiceLocator,portType,porttypeProxy and stub to create a java client

i have used axis web service client wizard + develop client slider for generating files as :
Mage_Api_Model_Server_HandlerBindingStub
Mage_Api_Model_Server_HandlerPortType
Mage_Api_Model_Server_HandlerPortTypeProxy
MagentoService
MagentoServiceLocator
please look at my post
i am trying to make a client some thing like this:
package Magento;
public class MyClient {
public static void main(String[] args) {
try{
MagentoServiceLocator msl = new MagentoServiceLocator();
MagentoService ms = (MagentoService) msl.WHICH_METHOD_TO_CALL();
double product_list = ms.catalogProductList;
System.out.println("Product List: " + product_list);
} catch (Exception e) {
e.printStackTrace();
}
}
}
any help i have tried to the best of mine but not getting which method should i call for accessing a php webservice method.
any help?

Create a client for the given wsdl and try this:
WebServiceSoapBindingStub stub = new WebServiceSoapBindingStub();
stub._setProperty(Stub.ENDPOINT_ADDRESS_PROPERTY, wsdlUrl);
WebService service = (WebService) stub;
service.authenticateUser(username,password); //service.yourservicename
More information that will help you.

Using the content handler API (JSR 211) to open applications

I want to be able to launch native and J2ME applications through my application using the content handler API (JSR 211) on a Nokia 6212.
At the moment, I am unable to do so, as it always states that there is "No Content Handler Found" and throws a javax.microedition.content.ContentHandlerException.
At the moment, I am trying to get the phone to launch its browser and go to a certain website, just to test that I can use the framework. I have tried many different Invocation objects:
//throw exceptions
new Invocation("http://www.somesite.com/index.html",
"application/internet-shortcut");
new Invocation("http://www.google.co.uk","text/html");
// a long shot, I know
new Invocation("http://www.somesite.com/text.txt","text/plain");
// massive long shot
new Invocation("http://www.google.co.uk","application/browser");
//appears to download the link and content (and definitely does in the Nokia
// emulator) and then throws an exception
new Invocation("http://www.google.co.uk");
new Invocation("http://www.somesite.com/index.html");
Below is the code that I have been using, please bear in mind the parameters often changed to generate the different Invocation objects.
/*
* Invokes an application using the Content Handler API
*/
public void doInvoke(String url, String mime, String payload){
Registry register = Registry.getRegistry(this.getClass().getName());
Invocation invoke = new Invocation(url, mime, null, false,
ContentHandler.ACTION_OPEN);
boolean mustQuit = false;
try {
mustQuit = register.invoke(invoke);
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (ContentHandlerException e) {
e.printStackTrace();
} catch (SecurityException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
if(mustQuit){
this.quit();
}
}

Try this:
Registry register = Registry.getRegistry(this.getClass().getName());
You must call Registry.getRegistry for the MIDlet inheritor. Just use your MIDlet for getting the class name.
