Sending an AutoGenerated Email

[divya narayan]

I am trying to send an AutoGeneratedEmail from my javaapplication.
The jar files I use are mail.jar and activation.jar. But somehow both are not compatible and my code does not work.
My code is

import java.util.Properties;
 
import javax.mail.Message;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
 
import org.dom4j.Element;
 
public class EmailUtils {

private static Session getSession() {
Properties props = new Properties();
props.put("mail.host", EmailAttributes.HOST_ADDRESS);
 
Session session = Session.getInstance(props);
return session;
}

public static void sendIfSaleEmail(String internetAddress, Element ele) {
MimeMessage msg = new MimeMessage(getSession());
try {
msg.setSubject("If Deal pending - please call ");
msg.setFrom();
 
String content = "To ["
+ ele.element("Seller").attributeValue("Label")
+ "] from ["
+ ele.element("AuctionDealer").attributeValue("Label")
+ "] - " + "If Bid Notification. On ["
+ ele.attributeValue("SaleDate") + "] at ["
+ ele.attributeValue("SellerTimeStamp") + "] you received "
+ "an If Bid in the amount of "
+ ele.attributeValue("Price")
+ " for the following vehicle: " + "["
+ ele.attributeValue("RunNo") + "] ["
+ ele.attributeValue("Year") + "] ["
+ ele.attributeValue("Make") + "] ["
+ ele.attributeValue("Model") + "] ["
+ ele.attributeValue("VIN") + "] [color] ["
+ ele.attributeValue("Mileage") + "]. "
+ "Please contact Missouri Auto Dealer's Exchange; ["
+ ele.element("AuctionDealer").attributeValue("PhoneData")
+ "] " + "at your earliest convenience.";
 
msg.setContent(content, "text/html");
msg.addRecipient(Message.RecipientType.TO,
new InternetAddress(EmailAttributes.RECIPIENT_TYPE_TO));
 
Transport.send(msg);
} catch (Exception e) {
 
}
}
 
}

And when I run without activation.jar it gives following error
Exception in thread "main" java.lang.NoClassDefFoundError: javax/activation/DataSource
at com.vero.vas.email.EmailUtils.sendIfSaleEmail(EmailUtils.java:33)
at com.vero.vas.client.app.TestSendingEmail.main(TestSendingEmail.java:12)

Can someone tell me how to know the dependancy of mail.jar on activation.jar?

Thanks in advance

Is your classpath set up correctly? Because that class is in activation.jar

[divya narayan]

Yes, my classpath is set correctly.
Since the program is getting compiled, classpath has to be set properly.

Does the versions of jar files make any difference?
If so please suggest me which versions i can use, my jdk is jdk1.5.0_11 and jre is jre1.5.0_11.

Thanks,
Divya

check the version of Javamail Api and JavaBeans Activation Framework(JAF)which contains mail.jar and activation.jar respectively and must include both jar files in classpath otherwise use JAVA SE6 because it already included the activation.jar

[divya narayan]

I have set classpath for both the jars.
The versions used are javamail-1_4_1.zip and jaf-1_1_1.zip respectively. Since my office uses this jdk version i cant update it to 6.

What else could be the reason?

Thanks,
Divya

Can we take a look at your classpath?

And also the path where the jars are contained?

Also how are you executing this program? As a stand alone Java Program or as part of some container based application?
