Webservice not accessible using cfinvoke,but emptystring in errordetail,filecontent using cfhttp

Hello,

When I am invoking the webservice with the following code. I am getting the following error.

Code that I have used is :

<CFINVOKE component="userinfo" METHOD="GetuserInfo" RETURNVARIABLE="result_info" >
     <cfinvokeargument name="EMP" value="123456"/>
</cfinvoke>
<cfdump var="#result_info#">

<CFINVOKE webservice="http://www.test.com/userinformation.cfc?wsdl" METHOD="GetVehInfo" RETURNVARIABLE="result_info" >
     <cfinvokeargument name="EMP" value="123456"/>
</cfinvoke>
<cfdump var="#result_info#">

We were able to call the component and get the output. While changing the same component as webservice by adding access="remote", we are able to navigate to the WSDL page. But, when we try to call the same, we receive the error.

Then , it worked while accessing a webservice using cfhttp .

We are facing another issue while accessing a java webservice using coldfusion (i.e., cfhttp) 

Coldfusion Server is in Windows Environment (i.e., consumer )

Java /J2eee code is hosted IBM application server in Unix Envionment (i..e., producer /service provider)

We are accessing the webservice url using the colfusion cfhttp method as below  with the WSL credential and soap request.

<cfhttp url="<<Webservicepath>>" method="post"  >
     <cfhttpparam type="header" name="content-type" value="text/xml">
     <cfhttpparam type="header" name="SOAPAction" value="<<SOAPACTIONPATH>>">
     <cfhttpparam type="header" name="content-length" value="#len(myxmlsoaprequest)#">
     <cfhttpparam type="header" name="charset" value="utf-8">
     <cfhttpparam type="cookie" name="WSL-credential" value="<<Cookie>>">
        <cfhttpparam type="xml" name="message" value="#myxmlsoaprequest#">
    </cfhttp>

We get cfhttp.filecontent as empty and cfhttp.errordetail as  empty as like below.

while checking further , we found that we have received the below error log information in the service provider server error log (UNiX).

DCSV1036W: DCS Stack DefaultCoreGroup at Member : An unusual connectivity state occured with member

details: alarm(): Closing the connection because members did not manage to connect.

Can you please advise
