I can abort the web service call from client by calling ABORT method of web service proxy. However at server where web service is hosted, the call only ends when it completes the processing.

EDIT: See Below I have a web service which uses a class of functions in order to return data used in various business processes (via InfoPath).

I'm looking for a C# example showing how to access a remote SOAP Web Service, and logging (to a file, or even just to a string I can do whatever with) all complete raw SOAP requests and complete raw SOAP responses. I found some other posts on StackOverflow with similar topics, but they seem to reference a web.config file, which my desk...
I think the question title neatly sums up what I am after. I have a web app and a service and I would like the build script to check if the service has been updated since the last build and if so, run the "update service reference" script that is available when you right-click on a service. Any ideas? ...

Hi all, I am connecting to a simple XML over HTTPS web service and getting a security exception. My question is whether you think the cause of this is the cert on the web server, so I should talk to the server admin or if my client code should be handling this. I would love to hear if anyone has encountered and solved this issue. Is the...

I have publicised a Java method as a Web Service and I use the Web Service Explorer in Eclipse to invoke it and it works as expected. See http://soa2world.blogspot.com/2008/05/soap-client-eclipse-web-service.html for screen shots (not taken by me). To ensure that this will also work against clients written in .NET I'd like to repeat th...
Hi guys, I'm setting up a project and one of the main questions is how to implement a simple message queueing system (something along the line of a messenger chat system). I would like to avoid polling, but there will most likely be a lot of concurrent connections (tens of thousands). These will be HTTP+SSL connections, started from an a...

Given a few words of input, I want to have a utility that will return a diverse set of relevant terms, phrases, or concepts. A caveat is that it would need to have a large graph of terms to begin with, or else the feature would not be very useful. For example, submitting "baseball" would return ["shortstop", "Babe Ruth", "foul ball",...

I know WCF has built in support for REST services; however, I'm looking at returning multiple types of data depending on the request. I would like the client to request the content type. So if they send text/html for example I would render my model into Html, if t...
Hi everyone, I’m trying to migrate a client side application from Axis to Axis 2. The application also supports connection through RMI so previously, we abstracted away the connection by using the stub and the locator file. For example, we did something like the following: AddFunctionLocator locator = new AddFunctionLocator (); AddF...
We implement the majority of our business rules in the database, using stored procs. I can never decide how best to pass data constraint violation errors from the database back to the user interface. The constraints I'm talking about are tied more to business rules than data integrity. For example, a db error such as "Cannot insert dup...
