ColdFusion SOAP Call

Using the following code:

<cfsavecontent variable="localscope.soapRequest">
      <cfoutput>
      <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
          <soap:Body xmlns:ns1="http://xmlns.oracle.com/pcbpel/adapter/db/top/getProjectByNumber">
              <ns1:getProjectByNumberSelect_TMANUMBERInputParameters>
                  <ns1:TMANUMBER>#form.tmanumber#</ns1:TMANUMBER>
              </ns1:getProjectByNumberSelect_TMANUMBERInputParameters>
          </soap:Body>
      </soap:Envelope>
      </cfoutput>
</cfsavecontent>

<cfhttp url="ENDPoint URI" method="POST">
      <cfhttpparam type="HEADER" name="Content-Type" value="text/xml; charset=utf-8">
      <cfhttpparam type="HEADER" name="User-Agent" value="Axis/1.1">
      <cfhttpparam type="HEADER" name="SOAPAction" value="operation name">
      <cfhttpparam type="BODY" value="#trim(localscope.soapRequest)#">
</cfhttp>

I am trying to initiate a SOAP call to a service on Oracle's ESB. I keep getting back "java.lang.NullPointerException." Any ideas as to why that is?
