Help Needed !!

Hi,

I am trying to extract Parsing and Msg convertion ability from this code. My requirement is build a REST api interface to convert .msg file in to .eml file.
I am more or less able to convert .msg file to Message object using MsgParser like below

MsgParser parser = new MsgParser();
Message msg = parser.parseMsg(new File("C:\Users\xyz\workspace\projects\demo\xyz.msg"));

However i am facing challenged in converting Message object to eml file using MsgWriter

MsgWriter writer = new MsgWriter();
writer.write(msg, new FileOutputStream("C:\Users\xyz\workspace\projects\demo\xyz.eml"));

These are the contents of my MsgContainer.write() method

public void write(Message msg, OutputStream out) throws IOException {
NPOIFSFileSystem fs = new NPOIFSFileSystem();
DirectoryNode root = fs.getRoot();
MsgContainer cont = new MsgContainer(msg);
cont.write(root);
fs.writeFilesystem(out);
fs.close();
}

Exception i see is

2020-03-03 10:52:37.069 INFO 18036 --- [nio-8080-exec-1] com.example.msgparser.MsgContainer : Msgontainer -> write null

java.lang.IllegalStateException: Can't read from a new stream before it has been written to

Please let me know if this is making sense or if you need more information.
Any help is much appreciated.

Hi @payadav, this is funny, you have the exact same requirement as in #15

MsgWriter's purpose is to write .msg files. You may want to look at class MessageParserFactory, especially around line 63 : https://github.com/lolo101/MsgViewer/blob/01c8db511085eefb8cdd6d13fafeac58592c3ed0/MSGViewer/src/main/java/net/sourceforge/MSGViewer/factory/MessageParserFactory.java

For a hint about how to write a .eml file

Hello @payadav, could you resolve the problem? I intend to close this issue in the next few days if it is no more needed
