JSESSIONID and setting cookie for WebServiceTemplate

[Sanjay Patil]

Hi Guys,

I am too working with cookies for my Spring webservices. Please can you show me the code tha you use on the Server side to generate a cookie and store the data in the cookie and send it back to the client.

Cheers,
Sanjay Patil

This is my servlet code:

package org.foo;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import org.springframework.ws.transport.http.MessageDispatcherServlet;

public class MyMessageDispatcherServlet extends MessageDispatcherServlet {
    @Override
    protected void doService(HttpServletRequest httpServletRequest,
            HttpServletResponse httpServletResponse) throws Exception {
        HttpSession session = httpServletRequest.getSession();
        super.doService(httpServletRequest, httpServletResponse);
    }
}

You need to change web.xml for your server to configure web services:

<!-- Spring-WS Servlet -->
<servlet>
     <servlet-name>WebServices</servlet-name>
     <servlet-class>org.foo.MyMessageDispatcherServlet</servlet-class>
     ...
</servlet>

Hi,

Thanks for the response. I do have some more queries now.

1. I want to call the webservices from a service class which is a POJO class, not from jsp or Servlet as shown above. So is there any Spring utility class I can use to get a handle to HttpServletRequest. I can see you guys have used below code for the same, which i guess is in a jsp file.

HttpServletRequest srequest = (HttpServletRequest) ((this.getPageContext()).getRequest());

I have not tried below code yet which I found on another forum log. I presume this will work only if I have server connection which is not the case for me.

TransportContext context = TransportContextHolder.getTransportContext();
HttpServletConnection connection = (HttpServletConnection) context.getConnection();
HttpServletRequest request = connection.getHttpServletRequest();


Cheers,

So you need to obtain JSESSIONID from somewhere to identify yourself with the webservice.

You need to store JSESSIONID which server generates at first HttpRequest, and then somehow pass it to the client code, so it can authenticate itself with same JSESSIONID as the code you posted shows. I don't know which technologies are you using, and what is the scenario of communication through WS. But when you have no previous Http communication with server, then you cant have any JSESSIONID. Dont know if i put this straight

Hi ,
i did some R&D in Spring webservices then after i got a idea to get the proper response from the service provide... in below i mentioned some code please try to follow...............




public String clientRequestWebService(final String productName, String xigniteBody) throws WebServiceTemplateException {

final StreamSource xigniteBodySource = new StreamSource(new StringReader(xigniteBody));
StreamResult result = new StreamResult(System.out);
log.debug("Resutl ::::: >>>>>>>> "+ result);

if(webServiceTemplate == null) {
throw new WebServiceTemplateException("Web Service Template Shouldn't be Null");
}

MyCommonsHttpMessageSender messageSender = new MyCommonsHttpMessageSender();

try {
messageSender.createConnection(new URI("http://www.xxxx.com/xCurrencies.asmx"));
} catch (IOException e) {
e.printStackTrace();
} catch (URISyntaxException e) {
e.printStackTrace();
}

webServiceTemplate.setMessageSender(messageSender) ;
webServiceTemplate.setDefaultUri("http://www.xxxx.com/xCurrencies.asmx?op="+ productName);

boolean flag = webServiceTemplate.sendSourceAndReceiveToResult( xigniteBodySource, new WebServiceMessageCallback() {
@Override
public void doWithMessage(WebServiceMessage arg0) throws IOException, TransformerException {

saajSoapMessage.getSaajMessage();
saajSoapMessage.setSoapAction( "http://www.xxxx.com/services/"+ productName);

StringSource headerSource = new StringSource(getRequestHeader());
SoapHeader soapHeader = ((SoapMessage) arg0).getSoapHeader();
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.transform(headerSource, soapHeader.getResult());
}
}, result );

log.debug("webServiceTemplate.sendSourceAndReceive ToResult Flag : "+ flag);

return null;
}

return sbHeader.toString();
}
