  • 1.  SOAP WS TRANSPORT CHUNK

    Posted Sun October 05, 2025 02:30 AM

    Hello everyone,

    I've successfully signed an XML document using SAAJ, and the digital signature is valid.
    However, when the message is sent through SOAP (using the JAX-WS client inside IBM WebSphere Application Server), the communication still uses
    Transfer-Encoding: chunked, which causes an error on the remote endpoint.

    If I send the same XML manually using HttpsURLConnection, it works perfectly - the request includes a fixed Content-Length header instead of chunked encoding.

    I've already tried the following in my client code:

    

    

    

    

    


    


    BindingProvider bp = (BindingProvider) port;
Map<String, Object> rc = bp.getRequestContext();
rc.put("com.sun.xml.ws.transport.http.client.streaming.chunk.size", -1);
rc.put("http.conduit.client.AllowChunking", "false");
System.setProperty("com.ibm.ws.websvcs.disableCOALESCING", "true");
System.setProperty("com.ibm.websphere.webservices.transport.OPTIMIZE_HTTP_HEADERS", "false");

    …but it seems these properties are ignored in the IBM Axis2-based JAX-WS runtime.

    Could someone confirm the correct way to disable chunked transfer encoding in WebSphere
    and force the client to send the Content-Length header instead?
    (For example, via JVM property -Dcom.ibm.websphere.webservices.useChunking=false or through the WebSphere console.)

    Any guidance or examples would be greatly appreciated.

    Thanks in advance,

    The problem is that com.ibm.websphere.webservices.useChunking=false propertie dons't work.

    Hi, A couple of things here.  You can turn off the chunking via the services policy set.  By default I believe it is set to true.  A chunk size of -1 is invalid.  http.conduit is invalid here.  Where did you get the useChunking?  Available JVM properties.
