I think you're doing this bit wrong.. see below.

Btw, using waitfor's is often faster than sleep statements:

<waitfor>
  <socket server="127.0.0.1" port="${port}"/>
</waitfor>

When you said:

 1) client sends XML doc to our servlet

This isn't what your script does here.  It would simply send:

POST /csb/CSBServlet HTTP/1.0
Content-length: xx

xmldoc=invalidCSBCreditApp.xml


If you want to POST an XML document content (not just the filename), then
you need something like:

<httpRequest href="${url}">
  <method>POST</method>
  <contentEquals href="invalidCSBCreditApp.xml"/>
  <match>
    <responseCode value="200" assign="rc"/>
  </match>
</httpRequest>

'contentEquals' sets (or tests) the HTTP body of the request.

Attached is a small script, intended to be run from examples/, which
demonstrates POSTing an XML file.
