Thanks for reverting back.
The line 16 of the NotifyMailet is the closing brace of function
service. No matter what I write in the service function or the class
NotifyMailet, James throws NullPointerException and the StackTrace
says the exception to be at line 16.
Here is the code of NotifyMailet.java
package mt;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.PrintWriter;
import java.io.StringWriter;
import javax.mail.MessagingException;
import org.apache.mailet.GenericMailet;
import org.apache.mailet.Mail;
import org.apache.mailet.MailAddress;
public class NotifyMailet extends GenericMailet {
public void service(Mail mail) throws MessagingException {
}
/**
* Gets the exception stack trace as a string.
* @param exception
* @return
*/
public String getStackTraceAsString(Exception exception)
{
StringWriter sw = new StringWriter();
PrintWriter pw = new PrintWriter(sw);
pw.print(" [ ");
pw.print(exception.getClass().getName());
pw.print(" ] ");
pw.print(exception.getMessage());
exception.printStackTrace(pw);
return sw.toString();
}
}
