com.moyosoft.exchange.util.ExchangeServiceClient

Represents an HTTP client accessing the Exchange Web Services (EWS). The method sendRequest is used to send a SOAP request over HTTP to the Exchange server and returns the received response.

A custom client can be used by implementing this interface. Usage example:

public class CustomServiceClient implements ExchangeServiceClient
{
  public ExchangeResponse sendRequest(ExchangeRequest request) throws ExchangeServiceException
  {
    try
    {
      HttpURLConnection connection = (HttpURLConnection) new URL("https://server/ews/Exchange.asmx").openConnection();
      connection.setDoInput(true);
      connection.setDoOutput(true);
      connection.setRequestMethod("POST");
      connection.connect();

      request.writeTo(connection.getOutputStream());

      return new ExchangeResponse(connection.getResponseCode(), connection.getResponseMessage(), connection.getInputStream());
    }
    catch(IOException ex)
    {
    }

    return null;
  }
}

A proxy client can also be implemented. Below is an example code showing how to print to the console all requests and responses exchanged:

public class ConsoleProxyClient implements ExchangeServiceClient
{
  private ExchangeServiceClient client;
  public ConsoleProxyClient(ExchangeServiceClient client) { this.client = client; }

  public ExchangeResponse sendRequest(ExchangeRequest request) throws ExchangeServiceException
  {
    System.out.println("Request: " + request.toString());
    ExchangeResponse response = client.sendRequest(request);
    System.out.print("Response: " + response.toString());
    return response;
  }
}

Exchange exchange = ...;
exchange.setClient(new ConsoleProxyClient(exchange.getClient()));
