java - Control what DataContentHandler to use for a MimeMessage attachment? -


i creating attachment mimemessage tiff image byte array.

bytearrayoutputstream out = new bytearrayoutputstream(); mimebodypart body = new mimebodypart(); body.setcontent(tiffbytearray, "image/tiff"); body.setdisposition("attachment"); body.setfilename(filename); mimemultipart multipart = new mimemultipart(); multipart.addbodypart(body); mimemessage message = new mimemessage(session.getdefaultinstance(system.getproperties())); message.setcontent(multipart); message.writeto(out); string mimecontent = out.tostring();

this works. image converted base64 string in message. however, @ point on system occurs , piece of code starts using com.sun.xml.internal.messaging.saaj.soap.imagedatacontenthandler. particular converted expects java.awt.image object opposed byte array (relevant source). following error:

unable encode image stream imagedatacontenthandler requires image object, given object of type class [b

i can see can set javax.activation.datahandler on javax.mail.internet.mimemessage , in datahandler can set javax.activation.datacontenthandlerfactory, i'm not sure set to.

is there way force byte array converted base64 encoded string regardless of mime type?

javax.mail provides datasource implementation bytes can explicitly use.

bytearraydatasource datasource = new bytearraydatasource(tiffbytearray, "image/tiff"); datahandler bytedatahandler = new datahandler(datasource); body.setdatahandler(bytedatahandler); body.setdisposition("attachment"); body.setfilename(filename);
