javax.mail.messagingexception: ioexception while sending message; nested exception is: java.io.ioexception: "text/html" datacontenthandler requires string object, given object of type class javax.mail.internet.mimemessage @ com.sun.mail.smtp.smtptransport.sendmessage(smtptransport.java:1167) if change setcontent multipart/mixed, get:
javax.mail.messagingexception: mime part of type "multipart/mixed" contains object of type javax.mail.internet.mimemessage instead of mimemultipart do have idea how can fix this? thanks.
remove
message.settext(mensagem); change
messagebodypart.setcontent(message, "multipart/mixed"); to
messagebodypart.settext(mensagem); and move , following line above "for" loop.
also, see this javamail faq entry of common mistakes.
