java - Start Mail-Client with Attachment? -

i'm searching way (in java) start default mail client defined receiver, subject , body , predefined attachment.

due limitations of rfc java.awt.desktop.mail-method not working attachments. jdic-project dead , jmapi-project rather obscure in building process. (needs 1.4 mozilla-sources) , have build 64 bit systems myself.

is there alternative? read articles here using rundl32.dll , such "solutions" aren't want put in production code.

there not appear os agnostic method of doing in java not oses provide standard way launch default e-mail application more basic fields new email.

on windows, possible use jni interface mapi, provide more control on opening email in mail application. mentioned, 1 such library jmapi - however, appears there many libraries such name similar purposes. discovered 1 maintained , seems straight-forward. includes pre-built binary dll , accompanying java jni-based library.

with code, seems need construct message object , call method launch in mail application: import jmapi.*; ...

    if (jmapi.ismapisupported()) {         message msg = new message();         msg.setsubject("test!");         msg.setbody("hello world");          list<string> toaddresses = new linkedlist<string>();         toaddresses.add("example@example.com");         msg.settoaddrs(toaddresses);          list<string> attachpaths = new linkedlist<string>();         //must absolute paths file         attachpaths.add("c:\users\documents\file.jpg");         msg.setattachments(attachpaths);          jmapi.open(msg);     }

another possibility might work windows , mac (and potentially other oses) generate ".eml" or ".msg" file content , attachments include encoded part of email. file launched default handler respective email file format. however, not guaranteed open default email handler, nor file format going compatible email client.
