I am trying to send a SwA message over HTTP to be parsed by the new MB 6.-0 MIME parse. I am using sun's SAAJ libraries to generate and send the SwA message. When the messsage is received I am receiving the exception "Empty or invalid header found at position: &1"; however the Content-Type is being populated in the HTTP header! If I save the message off to a file and then remove the first "POST..." line and put the message to a queue where it is sent to a flow, the message is parsed by the MIME parser without any exceptions. (Note this is the first time I have used the HTTP input node)

Below is the first part of the message with the first boundary being sent over HTTP:

POST http://localhost:7080/WBIMB/HTTP_WS HTTP/1.1
Content-Type: multipart/related; type="text/xml"; boundary="----=_Part_0_15655788.1133448443421"
Content-Length: 140990
SOAPAction: ""
Cache-Control: no-cache
Pragma: no-cache
User-Agent: Java/1.5.0_05
Host: localhost:7080
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Connection: keep-alive

------=_Part_0_15655788.1133448443421

And this is from a trace node after the HTTP input node:

(0x01000000):MIME = (
(0x01000000):Properties = (
(0x03000000):MessageSet = ''

(0x03000000):Connection = 'keep-alive'
)
(0x01000000):MIME =

and this is the exception being raised:

(0x03000000):Type = 14
(0x03000000):Text = 'MIME'
)
)
)
)

and finally this is from a user trace:
