Hi,
I am trying to compile a program and i am getting arond 19 "cannot resolve symbol" error.
I am using NT. I added C:\jdk1.3.1_02\bin to my path variable.
Also i created CLASSPATH variable which has the value
C:\jdk1.3.1_02\lib\tools.jar;C:\jdk1.3.1_02\lib\dt.jar.
Please let me know what is wrong in this.
Here is my program
-----------------------------------------------
import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
public class AttachExample {
public static void main (String args[])
throws Exception {
String host = args[0];
String from = args[1];
String to = args[2];
String fileAttachment = args[3];
// Get system properties
Properties props = System.getProperties();
// Setup mail server
props.put("mail.smtp.host", host);
// Get session
Session session =
Session.getInstance(props, null);
// Define message
MimeMessage message =
new MimeMessage(session);
message.setFrom(
new InternetAddress(from));
message.addRecipient(
Message.RecipientType.TO,
new InternetAddress(to));
message.setSubject(
"Hello JavaMail Attachment");
// create the message part
MimeBodyPart messageBodyPart =
new MimeBodyPart();
//fill message
messageBodyPart.setText("Hi");
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart);
// Part two is attachment
messageBodyPart = new MimeBodyPart();
DataSource source =
new FileDataSource(fileAttachment);
messageBodyPart.setDataHandler(
new DataHandler(source));
messageBodyPart.setFileName(fileAttachment);
multipart.addBodyPart(messageBodyPart);
// Put parts in message
message.setContent(multipart);
// Send the message
Transport.send( message );
}
}

You'll also need J2EE installed and the j2ee.jar file in your classpath. That's where the javax.mail, javax.mail.internet, and javax.activation packages are.

But i have this problem..
I am trying to run the file from c: drive as shown below
c:> java d:\report\AttachExample <host> <from> <to> <file>
but it is giving me the following error
"Exception in thread main java.lang.NoClassDefFoundError.

You cannot use a Java class that is not locatable in the classpath setting. Try instead
java -classpath %classpath%;d:\report AttachExample <host> <from> <to> <file>
