biztalk thread: Re: Transferring Zip Files in BizTalk Server


Message #1 by "Michael Earls" <michael@c...> on Tue, 3 Apr 2001 19:23:38 -0700
Search the web for a Base64 encoder.  This will convert the binary file to

text.  XML provides a mechanism by which this data can be stored in a CDATA

section.



When you have received the document on the other side, simply run a Base64

Decoder to rebuild it.  Think of it like the Star Trek transporter.



The content-type (MIME type) for a zip file is

"application/x-zip-compressed". You'll probably want to store this as an

attribute so your receiver can know what to do with it.



This is the same process that Internet Email programs use to perform the

same task since email messages can only be in text.



There are some drawbacks, though.  The size of the Base64 encoded file is

significantly larger than the original since all non-printable characters

that represent the binary data  must be converted to one of 64 printable

characters.  I'm not sure the exact size difference but I'm guessing that

it's about 3 times bigger than the original.





Good luck.  Let me know if you have any questions.

The problem is not the zip-file. The problem is to transfer binary data.

Using the winsock

is a simple way to do this. I have done this and it worked very well, but

not with the port 80, because

the webserver was listening on this port. configure your webserver to listen

on an other port or make

a port free on your firewall or something else.

Also think about safileup from SoftArtisans, this company has good

solutions to solve such problems.



Once more, biztalk can handle every type of file if you don't need

informations from these files to choose

the way documents go. That's because BizTalk Server put every information

into the XML body of it's own document

definition. So don't worry about the data that's written into it.



I hope this works,

Mirco
