Subject: AW: AW: [axis2-1.6.1] how to configire JAX-WS MTOM client / service programmatically Date: Mon, 24 Jun 2013 10:49:11 +0200 From: [email protected] To: [email protected] Hi Martin. very much thanks for your greate and extensive help; however I have still difficulties to get worlds together; there is on one part of what WE have, fully based on axis2-1.6.1/samples/jaxws-samples. And there is another part to be developerd to sniff in an option object and values to make things going. In the example code you find a jaxws for echo, ping and mtom. My file service is fully based on this mtom samples part found, slightly refactored to reflect the file service characteristics it should finaly have; it has a send method in the example; so as reference I started with the send() as well, which is just looping back an image depot. my service and client is then extended by a upload() and a download() method passing parameters i.e. a file path to the to be downloaded file. Now – we should look at the proxy server part of SamplesMTOMTests.java In the axis2-1.6.1/samples/jaxws-samples you can find in class SampleMTOMTests.java and there you can find * * @param result - String - used to pass back results to servlet. * @return String - the input string or null * @throws Exception */ public String testMtomWithProxy(String result, URL url) throws Exception { . . . // Setup the necessary JAX-WS artifacts try { if (soap12) { // Use the generated proxy MtomSample12PortProxy proxy = new MtomSample12PortProxy(url); proxy._getDescriptor().setEndpoint(uriString + urlSuffix); // Enable MTOM BindingProvider bp = (BindingProvider) proxy._getDescriptor().getProxy(); SOAPBinding binding = (SOAPBinding) bp.getBinding(); binding.setMTOMEnabled(true); // Send the image and process the response image response = proxy.sendImage(imageDepot); } else { // SOAP 1.1 Create the service // Use the generated proxy The part I have potentially to extend with an option object starts with if (soap12) buty might be similar for the else-part for soap11. What I do not know is: which classes on this examples I have to modify to sniff in / to get aa) service client or the like to get anb) optionsc) to pass options.setProperty(org.apache.axis2.transport.http.HTTPConstants.CHUNKED, Boolean.FALSE);d) to see if it passes binary data MG>modify SampleClient.java for options.setProperty MG>modify axis2.xml e.g<transportSender name="http" class="org.apache.axis2.transport.http.CommonsHTTPTransportSender"> <parameter name="PROTOCOL">HTTP/1.1</parameter> <parameter name="Transfer-Encoding">chunked</parameter> </transportSender>MG> options to be used following your explanations above. MtomSample12PortProxy proxy = new MtomSample12PortProxy(url); proxy._getDescriptor().setEndpoint(uriString + urlSuffix); // Enable MTOM BindingProvider bp = (BindingProvider) proxy._getDescriptor().getProxy(); SOAPBinding binding = (SOAPBinding) bp.getBinding(); binding.setMTOMEnabled(true); // Send the image and process the response image response = proxy.sendImage(imageDepot); MG>MTOMSampleServlet.java contains sample client whose options can be modified MG> try {... client.setOptions(uriString,Transfer-Encoding,"chunked");..

The closes I was is to get/ask for a request context to pass Map<String, Object> rc = proxy._getDescriptor().getDispatch().getRequestContext(); rc.put(HTTPConstants.CHUNKED, Boolean.FALSE); But that fails for reasons already explained in my previous e-mail. also and again: other data is also not passed to the context object as used by the sender.

MG>this isnt a proxy such as Spring injected Proxy so proxy is just a name to call the constructed object to act on our url MG>MtomSample12PortProxy proxy = new MtomSample12PortProxy(url); MG> public MtomSample12PortProxy(URL wsdlLocation) { MG>First param assigns a namespace that XSD will be using _descriptor = new Descriptor(wsdlLocation, new QName("http://org/apache/axis2/jaxws/samples/mtom/", "MtomSampleService12")); MG>the name of the service is MtomSampleService12 ,,,, public Descriptor(URL wsdlLocation, QName serviceName) { _service = new MtomSampleService12(wsdlLocation, serviceName); initCommon(); }... MG> } and for the jaxws-samples: It was a alltime my understanding that MTOM was for BINARY not for CHUNKED data!and that a MTOM sample should actually transfers BINARY data without going via all the options. Joint with MTOM enabled, if then CHUNKED is the default, sniffing in "\r\n" into the data stream to the service, then I get the impression that the way this is done is not so propper.

Note: a JAX-WS does not need a service.xml, so configuring the transport on a per-service-base for a given service using service.xml is a no-go So how can I configure my transport used in my JAX-WS client / JAX-WS service programmatically? again:if each clinet / servide has a Axis2.xml is it by definition assured that such type of "global configuration" are not overriding among already configured clients/service i.e. we have only 1 axis2 engine running; setting transfer encoding to chunked for webservice1 will transfer encoding binary for webservice2 also override transfer-encoding chunked for webservice1? are all configurations made in one of the many axis2.xmls influencing all web-services-configurations or only the on for which it is delivered in /WEB-INF/conf ?

How do I do that?jar -Dline.separator='\r' *.aarare you saying that maven builds must package my are using this line separator; again – how do I do that. Isn't this a maven-plugin issue?redeploy with admin toolOKand rerun the container with java -Dline.separator='\r' ContainerBootstrap.jarDo you refer to the Apache Jakarta Tomcat on OpenVMS here. I have problems with my client code only, kept on NetBeans 7.2.1 in JAVA. There my project, made of a client and a service part is built using maven. Is there any negotiation going on between client and server? Does ISO8859-1 somewhere above in the log file generate an indication that \r\n shall be used? But I think that should not lead MTOM to be non binary transparent. again – it cannot be a server/service issue because my .NET WCF 4.0 client runs fine/fast. But I think it is a question of what binary transparency under MTOM means and how it potentially can be that a sub module makes it no longer binary transparent. MTOM and binary transparency shall never look a t \r \n or just \n as this is just a pattern in a stream which can occur very frequently. As this client was running fine before, there must be a module, a jar coming in from a maven repo which gave me this non binary transparency. Intentionally I was never fiddling around with any such issues as this would not be "binary transparency" unless I run into this performance problems. and retry..anyway good hints about a generic problem.

A very performing CL/SV transfer aps, and the Vista task Manager showed close to 100% network utilization.Since a few days however, this is no longer the case for the java client, the network utilization has degraded to 1 to 2% and now the same transfer takes 4 to 5 minutes. Unacceptable.At the same time absolute no problem and close to 100% network utilization if I run my Visual Studio Test Suite of proxy based up and down load tests.If I changed something on my client side java code, that would be unintentionally. ! JBut any hint where I can start to hunt this phenomena would be very appreciated?I am launching my java client within NetBeans 7.2.1 for debugging and testing reasons, also it the past it was working so nicely.There is maybe one point I can make: When I used the NB debugger, I could see the "MultiThreadedHttpConnectionManager" doing some cleanup 'running' forever.What makes him running?Fiddling a bit around within the debug-view, I have seen an immediate Network utilization going up to 100% when this manager was suspended for a moment.as I have no clue what has happen then or how to catch it any hints are very welcome.Any hints welcome.RegardsJosef --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
