Characterset not supported by Outlook for messages from JavaMail w/ html

Question

Hi, I have a Java mail program which works fine for text as well as small html content. But when the html content grew, my outlook tells me that the characterset is not supported and my message (from java) is an attachment instead of body of message. Besides that it also adds other mail headers (from the mail server) and adds other characters in the message so I cannot even filter out the data or look at it by saving it as html file.
Whats going on?
Heres my code for mail:
try{
String host = "mailserver";
String from = fr; // this is passed as paramter
String to = t; // this is also passed as parameter
String subject = "Error occured in Process.";
String content = cont; // cont is the message which is passed as string and contains html
content = content.concat("\n\nNote:\n\nThis message was generated by manually running the program.");
String attachmentFile = "c:\\grab.gif"; // file to be attached.
String bodyOfAttachment = "<h3>This is the body of attachment.</h3>";
Properties props = System.getProperties();
props.put("mail.smtp.host", host);
Session session = Session.getDefaultInstance(props, null);
Message message = new MimeMessage(session);
message.setSubject(subject);
message.setFrom(new InternetAddress(from));
message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
MimeMultipart multipart1 =new MimeMultipart("alternative");
BodyPart part=new MimeBodyPart();
part.setContent(content,"text/html");
multipart1.addBodyPart(part);
BodyPart messageBodyPart = new MimeBodyPart();
String htmlText = bodyOfAttachment;
messageBodyPart.setContent(htmlText, "text/html");
MimeMultipart multipart = new MimeMultipart("related");
multipart.addBodyPart(messageBodyPart);
messageBodyPart = new MimeBodyPart();
DataSource fds = new FileDataSource(attachmentFile);
messageBodyPart.setDataHandler(new DataHandler(fds));
//messageBodyPart.setHeader("Content-ID","<"+"memememe"+">");
multipart.addBodyPart(messageBodyPart);
MimeBodyPart mbp = new MimeBodyPart();
//Comment these two lines to not send attachment
//--mbp.setContent(multipart);
//--multipart1.addBodyPart(mbp);
message.setContent(multipart1);
Transport.send(message);
catch (AddressException ae){
     ae.printStackTrace();
catch (MessagingException me){
     me.printStackTrace();
}

Never mind I figured it out.
replace all occurences of
"text/html"
with
"text/html;charset=ISO-8859-1"
