java - How to add clicable a href to attachment of email sended from javax.mail -

-

i sending email javax.mail.

i sending attachments (some files, example pdf.)

i want add link attachment email body this:

dear user, can download file in attachment link "download"

my code is:

    string cidlinks = "<br>";     int counter = 0;     (string attachments : email.pathtoattachments) {         string ciddata = "<data" + (counter) + ">";         mimebodypart mimebodypart = buildmimebodypart(attachments, ciddata);         multipart.addbodypart(mimebodypart);         counter++;         cidlinks += "<a href='cid:" + ciddata + "'> " + mimebodypart.getfilename() + "</a>" + "<br>";     }

and mimebuilder is:

private mimebodypart buildmimebodypart(string path, string id) {     mimebodypart emailmemebodypart = new mimebodypart();     try {         datasource source = new filedatasource(path);         emailmemebodypart.setdatahandler(new datahandler(source));         emailmemebodypart.setfilename(source.getname());         emailmemebodypart.setcontentid(id);     } catch (exception e) {         system.out.println("err: " + e.getmessage());     }     return emailmemebodypart; }
