Apache HttpClient PostMan

When using the apache.HttpClient to send a multipart, I generate the following output as below:

18:29:58.800 DEBUG n.n.n.w.e.ServiceImpl - 

--bEDi1DhmFcmCTebUvLowWpRtw-OscIydQ24RSB
Content-Disposition: form-data; name="id"
Content-Type: text/plain; charset=ISO-8859-1
Content-Transfer-Encoding: 8bit

ChecknLoadEnvironmentData
--bEDi1DhmFcmCTebUvLowWpRtw-OscIydQ24RSB
Content-Disposition: form-data; name="file"; filename="myfile.xml"
Content-Type: text/xml; charset=ISO-8859-1
Content-Transfer-Encoding: binary

<?xml version="1.0" encoding="ISO-8859-1" ?>
<Dataset xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <ImportProgramVersion>3.1</ImportProgramVersion> 
    <Year>2012</Year> 
    ....
    .... 
</Dataset>
--bEDi1DhmFcmCTebUvLowWpRtw-OscIydQ24RSB--

But this seems to fail with a 500 internal server error and it succeeds with PostMan.

----WebKitFormBoundaryE19zNvXGzXaLvS5C
Content-Disposition: form-data; name="id"

ChecknLoadEnvironmentData
----WebKitFormBoundaryE19zNvXGzXaLvS5C
Content-Disposition: form-data; name="filename"

myXML.xml
----WebKitFormBoundaryE19zNvXGzXaLvS5C
Content-Disposition: form-data; name="file"; filename="myXML.xml"
Content-Type: text/xml


----WebKitFormBoundaryE19zNvXGzXaLvS5C

So my question is, can I remove the charset and content-transfer-encoding in java with "apache.httpclient"? So I can eliminate the differences between the two requests. I looked into the library source and does not seem to be possible, it will always default to some value.

(Why does Postman not display my sending xml file?)

Make sure to use the so called 'lax' mode when generating multipart mime entities with Apache HttpClient
