How to differentiate between html content and non-html content of javamail?

try including a separate Part in the email containing plain text

ASKER

I'm not really clear.

ASKER

That's means for send non-html use a different code? But how to differentiate that the content is html or non-html, the content is from the jsp page.

if you are sending as HTML, you need to send the HTML source. for e.g.,

<html>

<body>
ITEM A
ITEM B
ITEM C
</body>
</html>

not, ksivananth. for content below I want send it as non-html.

The List

ITEM A
ITEM B
ITEM C

Supposely, the app can send both of non-html and html. That means at one time sender can send either html and non-html. But I think must do something for identify wheter the content is html or non-html. But, I do not how. Previously I use code below for send, it not work for html.

MimeBodyPart mbp = new MimeBodyPart();
mbp.setText(messageTxt);			
Multipart mp = new MimeMultipart();
mp.addBodyPart(mbp);
msg.setContent(mp);

Do you means for html set it as
htmlPart.setContent(messageTxt, "text/html");

and for non-html
plainPart.setContent(plainTxt, "text/plain");

yes

ASKER

I will continue tomorrow, I need to go back. Thanks objects ...

>>not, ksivananth. for content below I want send it as non-html.

thats why I mentioned plainPart.setContent(plainTxt, "text/plain");

ksivananth,

try reading this article. hopefully, it will give you a better understanding of the differences in formatting content to be sent as HTML, as opposed to text only, emails.

ASKER

Right now I understand that for html use ---> htmlPart.setContent(messageTxt, "text/html");
for plain text use ---> plainPart.setContent(plainTxt, "text/plain");

In the application the sender can insert the content anything So, based on the content it will go wheter (htmlPart.setContent(messageTxt, "text/html");) or (plainPart.setContent(plainTxt, "text/plain"); )

for example
[1] -- if(content plaintext) {(plainPart.setContent(plainTxt, "text/plain"); )}
[2] -- if(content html) {(htmlPart.setContent(messageTxt, "text/html");)}

That means:
If the content like below it will go to [1] condtion:

LIST
ITEM A
ITEM B
ITEM C

Meanwhile, when the content like below, it will go to [2] condition:
<html>

<body>
ITEM A
ITEM B
ITEM C
</body>
</html>

but I do not have an idea how to make a condition, can anyone me give an idea how to do that or is it can be solve with another solution.

>>and another small suggestion

may be small but critical in most cases if it is intended for wide audiances!

ASKER

yup, I'm already done for multipart. That means, it not possible for handle both plaintext and html.

ASKER

hurmm, but I must do for both.

ASKER

I got an idea, so make the condition based on the content structure.

ASKER

here is what i did. Is it anyone have a better solution to solve this? I hope someone can help me, I'm quite new with java.

StringBuilder sb = new StringBuilder(body);
index1=sb.indexOf("<!DOCTYPE");
index2=sb.indexOf("<html");
index3=sb.indexOf("<body");
index4=sb.indexOf("</body>");
index5=sb.indexOf("</html>");
				    
if ((((index1 != -1)||(index2 != -1))&&(index3 != -1)&&(index4 != -1)&&(index5 != -1)) && (((index1 < index2)||(index2 < index3)||(index3 < index4)||(index4 < index5)))) {
 
String newMessage = insertSign(sb,index4);
				    				    MimeMultipart mp = new MimeMultipart("alternative");
MimeBodyPart text = new MimeBodyPart();
MimeBodyPart html = new MimeBodyPart();
						text.setText(newMessage);
						html.setContent(newMessage, "text/html");
mp.addBodyPart(text);
mp.addBodyPart(html);
msg.setContent(mp);
Transport.send(msg);
}
else {
messageTxt = body+"\n \n \n "+signature;
Multipart mp = new MimeMultipart();
MimeBodyPart plainPart = new MimeBodyPart()
plainPart.setContent(messageTxt, "text/plain");                   
mp.addBodyPart(plainPart);  
msg.setContent(mp);
Transport.send(msg);
				         }			          	    
}

something like that should work, not foolproof of course
