I am also getting the same error even after using Spring 3.0.5.RELEASE and Hibernate 3.3.2.GA.

My appContext is as follows:

Also I tried executing the same client program by giving the proxy settings, this time only the client side gave the following exception message
{http://xml.apache.org/axis/}HttpErrorCode:502

Exception in thread "main"

I understand by the above message(s) that the Item class is giving a serialization exception but the class on the server side does implement the [b]java.io.Serializable interface[b] and so does the Item class that gets generated using the WSDL2Java utility.

Can anyone figure out the reason behind this exception being thrown?

Do the other local Java programs actually use the DNS-based address of the machine (causing it to go out on the network pass through the firewall(s) and come back) or are they actually using a "localhost" or 127.0.0.1 (loopback) based address (i.e. they never leave the local machine)?

The other local Java programs do use the DNS-based address of the machine but since the client programs and the server are residing on the same physical machine I do not think they go out on the network.

Also in the other Java programs I have not made any proxy settings but they still work fine. And if I do the same for the current program that is returning me the error code 502, a java.net.ConnectException is thrown.

I have published a web service on my local machine and am trying to consume it locally too. When I access the WSDL no errors are generated but when I execute a client program to consume the same web service the following exception message is thrown.

Can anyone tell me as to why a proxy error is thrown, when I have already done the necessary proxy settings in the client code and also when the other client Java programs to consume other locally published web services work without any errors.

Hi,

I want to know if there is any method for accessing a file uploaded in a JSP and sent to a servlet in an HttpResponse object. I have seen the code using the org.apache.commons.fileupload.* package classes.

My problem is that using the org.apache.commons.fileupload.FileItemFactory or org.apache.commons.fileupload.FileItem object, the uploaded file gets temporarily stored onto the disk. Is there any other method by which I can access the file stream from the HttpResponse object directly?

Hi Balaji,

Thanks for the links... I got to know about the web service throught www.xmethods.net website... and hence I have no clue how the web service is actually implemented...

Hi Balaji,

Can you suggest some book or site that can tell me more about Axis or Web Services programming in greater detail? Please give me the reference of a book or link that is freely available on the internet.

Thank you very much for your solution ... it worked!!!

Hi,

I just wrote a code where in I invoke an operation on an external webservice using the org.apache.axis.client.Call object. The operation I am intending to invoke takes no parameters, hence I called the call.invoke() method that takes no parameters but this threw a java.lang.NullPointerException. But if try calling the invoke() method that takes an Object array and pass it an uninitialized array like call.invoke(new Object[]{}), a org.xml.sax.SAXException: SimpleDeserializer encountered a child element, which is NOT expected, in something it was trying to deserialize. message is given.
The operation called takes no parameters but returns an Object array. What should be done in the code? The code written by me is as follows:
package test.client; import java.rmi.RemoteException; import java.util.List; import javax.xml.namespace.QName; import javax.xml.rpc.ServiceException; import org.apache.axis.client.Call; import org.apache.axis.client.Service; import org.oorsprong.www.websamples_countryinfo.TCountryCodeAndName; public class CISNewClient { public static void main(String[] args) throws ServiceException, RemoteException { System.setProperty("proxySet", "true"); System.setProperty("http.proxyHost", "proxyHost"); System.setProperty("http.proxyPort", "proxyPort"); System.setProperty("http.proxyUser", "username"); System.setProperty("http.proxyPassword", "password"); String endpoint = "http://www.oorsprong.org/websamples.countryinfo/CountryInfoService.wso?WSDL"; Service service = new Service(new QName("http://www.oorsprong.org/websamples.countryinfo", "CountryInfoService")); Call call = (Call)service.createCall(); call.setTargetEndpointAddress(endpoint); call.setOperationName(new QName("http://www.oorsprong.org/websamples.countryinfo", "ListOfCountryNamesByName")); TCountryCodeAndName[] ret = (TCountryCodeAndName[])call.invoke(new Object[] {}); System.out.println("Sent \"1\", got \"" + ret +"\""); } }

Hi,
I am trying to access a webservice but my machine has to route the request to create a service through a proxy. I can execute WSDL2Java at command line by giving the -Dhttp.proxyHost and -Dhttp.proxyPort for the JVM and -U and -P options for WSDL2Java.
I want to do the same for a client program and so I tried setting the System properties with http.proxyHost, http.proxyPort, http.proxyUser and http.proxyPassword but that gives a IOException with message Server returned HTTP response code: 407 for URL <a href="http://....</b rel="nofollow">" target="_blank">http://....
I have also tried using Authenticator.setAuthenticator(MyAuthenticatorClass) and that gives the following response javax.xml.rpc.ServiceException: Error processing WSDL document: java.net.ConnectException: Connection timed out: connect[/B]
I also have tried using TransportClientProperties class and using the -Dorg.apache.axis.components.net.TransportClientProperties=MyTransportClientProperties
command line VM option but this too results in the same output as given above.

Can anyone tell me what else can I do to get through the proxy to access the service/wsdl?
