ews-java-api-无法设置类的实例

Question

im trying to develop ews-java-api simple program. i am following the guide and it shows how to set an ExchangeService variable name "service".

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
ExchangeCredentials credentials = new WebCredentials("emailAddress", "password");
service.setCredentials(credentials);

i've made it and it's all good.

then it shows how to create a message variable class, under the title "sending a message"

EmailMessage msg= new EmailMessage(service);
msg.setSubject("Hello world!");
msg.setBody(MessageBody.getMessageBodyFromText("Sent using the EWS Java API."));
msg.getToRecipients().add("someone@contoso.com");
msg.send();

my program won't accept it. i get an error:

Exception in thread "main" java.lang.Error: Unresolved compilation problem: 
    Unhandled exception type Exception

    at project2.liran.main(liran.java:19)

here is my program as i wrote it:

package project2;

import microsoft.exchange.webservices.data.core.ExchangeService;
import microsoft.exchange.webservices.data.core.enumeration.misc.ExchangeVersion;
import microsoft.exchange.webservices.data.core.service.item.Appointment;
import microsoft.exchange.webservices.data.core.service.item.EmailMessage;
import microsoft.exchange.webservices.data.credential.ExchangeCredentials;
import microsoft.exchange.webservices.data.credential.WebCredentials;
import java.net.*;


public class liran {
    public static void main(String[] args) {        
    ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP1);
    ExchangeCredentials credentials = new WebCredentials("emailAddress", "password");
    service.setCredentials(credentials);
    URI uri = URI.create ("http://www.cnn.com");
    service.setUrl(uri);
    EmailMessage msg= new EmailMessage(service);
    }

}

what am i doing wrong?

Answer 1

It is exactly as the error message states. In line no 19, the Checked Exception is not handled. The Constructor for EmailMessage has throws Exception clause and so your program must handle it.

This is the constructor:

 public EmailMessage(ExchangeService service) throws Exception {
    super(service);
  }

I would advise you to go with an IDE (Eclipse, Netbeans, IntelliJ IDEA) for your development.

Visit Oracle's Exception Handling for more information.
