Stateful web service
Hello, How can I write a simple stateful web service service and how can I call this in a standalone Java application ? Is there any simple example? Best regards, Eric - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Stateful web service
Two common ways are with soap sessions or rolling your own via something like ehcache and java.util.UUID. Both have their advantages and disadvantages. The latter comes with axis2 but AFAIK doesn't have recovery after server shutdown, though something like sandesha might. The former also has a lot of rules to be aware of. The latter requires some coding yourself but its pretty simple. It also is independent of axis2 . The latter has the disadvantage that there are few docs showing how to do it, but again its just a cache and passing and returning a token on login and then passing it back in. The former (may have something more current around) : http://www.developer.com/java/web/article.php/3620661 The latter - in português from me and needs a better example - just ignore if not interested.

[Axis2] how to create an admin module for stateful web service
Hi all, I have to set up a web application to monitor a stateful web service. I guess the result should be like the axis2 admin module. Is there any way to do this? If yes, how can I do it? Any advice would be appreciated, Michele - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: stateful web service
In the client call you need to set MaintainSession true. Excuse the brief reply but I'm BAAF. Shaowei Mao wrote: Hi, I implemented a web service by generating stub and skeleton from wsdl.

Re: Stateful Web Service
This is how i have done it..
Some of the people over in this forum suggested the same..
Make your servlet webservice endpoint interface implement javax.xml.rpc.server.ServiceLifecycle interface
Than you need to define init() and destroy() methods.
Using ServletEndpointContext you can retrieve HTTPSession and thats what you need to maintain state.
Implement your backend logic in stateless EJBs
given below is a small snippet from my servlet endpoint
Cheers
javax.xml.rpc.server.ServletEndpointContext servletContext;
/** * */
public void init(Object context) {servletContext = (javax.xml.rpc.server.ServletEndpointContext) context;}
/** * */public void destroy() {servletContext = null;}

Re: Stateful Web Service
Hi Prashanth,
Can you let me know as to how to retreive the HTTPSession from
ServletEndpointContext ?

Re: Stateful Web Service
Use its getHTTPSession() method.
You might want to learn to use APIs' javadocs. Just google for
ServletEndpointContext, the Javadoc is its first find.

Re: Stateful Web Service
Hi,
I actually got it. I had notadded the servlet jar file into the project in eclipse and therefore was not getting the getHttpSession Method. Anyways thanks for the reply.
