Hi I am trying to write spring ws client which connect via proxy.

This is mine configuration:

Could someone give me a hint how to solve this ?

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);
                }
            }
        }
    }

            }
        }
    }

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.

yayy! I was having the exact same issue.. Thanks for that hint de_tom

I was having the same issue...thank you very much!
