We are working on performance tuning of camel spring-ws API to support high TPS. we are trying to override default connection properties of HttpComponentsMessageSender with custom spring-webservice template based on below spring-ws doc , but with no luck.

https://camel.apache.org/components/3.15.x/spring-ws-component.html

camel.version -3.0.1 spring-boot-version - 2.6.3

Camel Route

.doTry()
        .to(dStreamPath)

Spring WS YAML Config

dStreamPath: spring-ws:http://URL/getOffers?webServiceTemplate=#customSpringWSTemplate&soapAction=http://www.url.org

Bean Config

@Bean(name = "customSpringWSTemplate")
   public WebServiceTemplate webServiceTemplate() throws Exception {
    final MessageFactory msgFactory = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL);
    final SaajSoapMessageFactory saajSoapMessageFactory = new SaajSoapMessageFactory(msgFactory);
    final WebServiceTemplate customSpringWSTemplate = new WebServiceTemplate(saajSoapMessageFactory);
    HttpComponentsMessageSender httpMessageSender = new HttpComponentsMessageSender();
    httpMessageSender.setMaxConnectionsPerHost(new HashMap<String, String>() {
        { put("http://URL/getOffers", "20");}
    });
    httpMessageSender.setMaxTotalConnections(100);

    customSpringWSTemplate.setMessageSender(httpMessageSender);
    return customSpringWSTemplate;
}

Error :
