Unable to send mail via Web Service

[ashish malhotra]

I created a simple JAVA program to send email, below is the code. It accepts 3 paramters, the ToEmail Id, Subject, and DataHandler object which contains a file which needs to be attached in the mail

public String aToEmailAddr,String aSubject,DataHandler dataHandler){

Properties fMailServerConfig = new Properties();
refreshConfig(fMailServerConfig);

Session session = Session.getDefaultInstance( fMailServerConfig, null );

MimeMessage message = new MimeMessage( session );
try {

message.setFrom( new InternetAddress(fMailServerConfig.getProperty("mail.FromEmailAddr" )) );
message.addRecipients(Message.RecipientType.TO, aToEmailAddr);
message.setSubject( aSubject);

MimeBodyPart messageBodyPart = new MimeBodyPart();
//fill message
messageBodyPart.setText(fMailServerConfig.getProperty("mail.Body" ));

Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart);

messageBodyPart = new MimeBodyPart();
multipart.addBodyPart(messageBodyPart);

// Put parts in message
message.setContent(multipart);

Transport.send(message);
}
catch (Exception ex){
ex.printStackTrace();
System.err.println("Cannot send email. " + ex);
}
}

When I test this Java program as a simple Java application, it works. I get the email with attachment. However if I convert it into a Web Service, It doesnt work.. I'm testing the Web Service using the below Client code.

public static void main(String[] args) {
String endpoint = "http://localhost:8080/SendEMail/services/Emailer";
Service service = new Service();
try {
Call call = (Call) service.createCall();
call.setTargetEndpointAddress( new java.net.URL(endpoint) );
call.setOperationName(new QName("http://send.mail.com/", "sendEmail") );

String fileAttachment = "Sample.txt";

DataSource source = new FileDataSource(fileAttachment);
DataHandler dataHandler= new DataHandler(source);

call.invoke( new Object[] {"[e-mail]","Blank Subject",dataHandler} );

} catch (Exception e) {
System.out.println("-------------"+e.toString());
e.printStackTrace();
}
}

I have verified that the Web service is configured correctly. If I add sysouts in Web service method, and invoke the client, i do see the sysouts on server console. So the request is reaching the webservice. But the exception is coming at the following line of web service method

Transport.send(message);

Below mentioned stack trace appears on client console (No exception on server console)
