    Default Use an interceptor

    Hi,

    you can take a look at
    Code:
    org.springframework.ws.transport.http.HttpComponentsMessageSender
    they are using an interceptor:
    Code:
    DefaultHttpClient defaultClient = new DefaultHttpClient(new ThreadSafeClientConnManager());
defaultClient.addRequestInterceptor(new RemoveSoapHeadersInterceptor(), 0);
    to remove the content-length:
    Code:
    private static class RemoveSoapHeadersInterceptor implements HttpRequestInterceptor {

        public void process(HttpRequest request, HttpContext context) throws HttpException, IOException {
            if (request instanceof HttpEntityEnclosingRequest) {
                if (request.containsHeader(HTTP.TRANSFER_ENCODING)) {
                    request.removeHeaders(HTTP.TRANSFER_ENCODING);
                }
                if (request.containsHeader(HTTP.CONTENT_LEN)) {
                    request.removeHeaders(HTTP.CONTENT_LEN);
                }
            }
        }
    }

                if (request.containsHeader(HTTP.TRANSFER_ENCODING)) {
                    request.removeHeaders(HTTP.TRANSFER_ENCODING);
                }
                if (request.containsHeader(HTTP.CONTENT_LEN)) {
                    request.removeHeaders(HTTP.CONTENT_LEN);
                }
            }
        }
    }
    Thanks for a hint!
    As a workaround, I have subclassed the DefaultHttpClient like this:

    public class MyDefaultHttpClient extends DefaultHttpClient{

    protected BasicHttpProcessor createHttpProcessor() {
    BasicHttpProcessor processor = super.createHttpProcessor();
    processor.addInterceptor(new RemoveHttpHeadersInterceptor(), 0);
    return processor;
    }

    public MyDefaultHttpClient(org.apache.http.impl.conn.Pool ingClientConnectionManager connManager){
    super(connManager);
    }
    }

    And RemoveHttpHeadersInterceptor is:
    public class RemoveHttpHeadersInterceptor implements HttpRequestInterceptor{

    public void process(HttpRequest request, HttpContext context) throws HttpException, IOException {
    if (request instanceof HttpEntityEnclosingRequest) {
    if (request.containsHeader(HTTP.TRANSFER_ENCODING)) {
    request.removeHeaders(HTTP.TRANSFER_ENCODING);
    }
    if (request.containsHeader(HTTP.CONTENT_LEN)) {
    request.removeHeaders(HTTP.CONTENT_LEN);
    }
    }
    }
    }

    and in my configuration I made change:
    <!-- http client definition -->
    <bean id="httpClient" class="ru.chernykh.MyDefaultHttpClient">
    <constructor-arg>
    <ref bean="connmanager"/>
    </constructor-arg>
    <property name="params" ref="httpParams" />
    </bean>

    Thanks to this, I can successfully run the ws client.
