New to java... Having problems with Stringbuffer - FileReader

Question

I believe what I am trying to do is quite simple but I am missing something...
Basically I need to read the contents of a text file and append the text to an email message. As I said, I am new to java and I certainly don't understand everything, but I will do my best to answer any questions you may have.
My attempt at writing the code is below. The relevant sections are in bold
private void emailDevLicense(HttpServletRequest request, HttpServletResponse response, String operatorId) {
String configId = request.getParameter("configurationId");
String deployPath = cdlcmConfig.getLmLicensePath();
String cName = request.getParameter("cName");
String aName = request.getParameter("aName");
String lPath = request.getParameter("lPath");
String licenseName = request.getParameter("name");
String description = request.getParameter("licenseConfigDesc");
String contents = null;
Properties emailProperties = new Properties();
emailProperties.put("mail.smtp.host", cdlcmConfig.getEmsMailServer());
Session mailSession = Session.getDefaultInstance(emailProperties, null);
String mailFrom = cdlcmConfig.getEmsMailFrom();
MimeMessage message = new MimeMessage(mailSession);
MimeBodyPart p1 = new MimeBodyPart();
MimeBodyPart p2 = new MimeBodyPart();
MimeBodyPart p3 = new MimeBodyPart();
String operatorName = DbHelper.getOperatorName(operatorId);
String recipient = "[email protected]";
String filename1 = deployPath + "/l-" + configId + "/license.dat";
String filename2 = deployPath + "/l-" + configId + "/company.dat";
log.info("emailDevLicense");
*try {*
File f = new File(lPath, "license.dat");
BufferedReader br = new BufferedReader(new FileReader(f));
StringBuffer sb = new StringBuffer();
String eachLine = br.readLine();
*while (eachLine != null) {*
eachLine = br.readLine();
sb.append(contents); }
*catch (java.io.FileNotFoundException ex) {*
log.error("Unable to find license file license.dat", ex);
*catch (java.io.IOException ex) {*
log.error("Unable to read lines from license.dat", ex);
try {
/* Set user-entered RFC822 headers to a message (mmsg). */
message.setHeader ("From", "[email protected]");
message.setHeader ("Reply-To", "[email protected]");
message.setHeader ("To", recipient);
message.setSubject("License files for Customer Name: " + cName + " / Account Name: " + aName + "");
/* Add any other desired headers. */
p1.setText("Configuration Name: " + licenseName + "\n\nOrder Number: " + description + "" + contents + "");
// Put a file in the second part
FileDataSource fds1 = new FileDataSource(filename1);
p2.setDataHandler(new DataHandler(fds1));
p2.setFileName(fds1.getName());
// Put a file in the second part
FileDataSource fds2 = new FileDataSource(filename2);
p3.setDataHandler(new DataHandler(fds2));
p3.setFileName(fds2.getName());
// Create the Multipart. Add BodyParts to it.
Multipart mp = new MimeMultipart();
mp.addBodyPart(p1);
mp.addBodyPart(p2);
mp.addBodyPart(p3);
// Set Multipart as the message's content
message.setContent(mp);
log.info("Sending Dev License");
Transport.send(message);
} catch (MessagingException ex) {
log.error("Unable to send license mail to address " + recipient, ex);
}

You guys\gals rock...
This solved my problem and taught me something in the process. I have been trying to do this myself for 3 days now...so...thanks so much for the help.
Once that worked I had to add a return after each line was read and I actually got that right on the first try.
The final code is below.
Thanks everyone..
try {
            File f = new File(lPath, "license.dat");
            BufferedReader br = new BufferedReader(new FileReader(f));
            StringBuffer sb = new StringBuffer();
            String eachLine = br.readLine();
            while (eachLine != null) {
                sb.append(eachLine + "\n");
                eachLine = br.readLine();
           contents = sb.toString();
            catch (java.io.FileNotFoundException ex) {
            log.error("Unable to find license file license.dat", ex);
            catch (java.io.IOException ex) {
            log.error("Unable to read lines from license.dat", ex);
            }
