Are There Any Transactions Around Multiple Webservice Calls
Mar 31, 2011
Are there any transactions around multiple webservice calls.Let me start with a commonly used example -- the travel agency. A customer intends to create a travel plan through an online travel agency. To do this, the online travel application calls the following three Web services:
-Air ticket booking
-Hotel reservation
-Taxi reservation
These three services are available from three separate vendors. If any one of these three services fails, the customer does not wish to proceed with the transaction (again, either all three services must succeed or none at all).My language programming is Asp.net c#.

I have a webservice (ASP.NET) deployed on a webfarm. A client application consumes it on daily basis. The problem is that some of its calls are duplicated (with difference of milliseconds). For example I have a function Foo(string a,string b). The client app calls this webmethod as Foo('test1','test2') once but my log shows that it is being called twice or sometimes 3 or 4 times randomly. Is this anything wrong with the webfarm or the code? Note that the webmethod has simple straighfarward insert and update statements.

I need to know the best way to do the following. I have nested business level APIs (say level 1 & level 2). L1 needs to call L2. Both APIs use the database layer directly at their own nesting levels.
Now, in the database layer, I fetch the db connection from the pool each time as follows:
SqlConnection conn = new SqlConnection(connString);
conn.Open();
Is it proper to fetch the db connection each time on every DB level call as above? I know it will return a connection from the ASP.NET connection pool. However, wouldn't it be better to maintain the same DB connection throughout the nested calls (or throughout the current http request lifetime)? Will fetching a connection from the pool each time cause issues with nested TransactionScopes?

I have data that is stored on a local machine and periodically replicated using webservices. This data is critical to the application of this program and is along the lines of business transactions.
TransactionHeader JOIN TransactionDetail
So forth.
Should I be using some type of CRC checking when sending the data to the webservice or is this handled by the TCP protocol itself sufficiently?
EDIT: Just to be clear the data isnt deleted from the client until the server acknowledges receipt and I use strongly typed parameters in my webservice but I am more thinking about "mangled" data (although in all cases but string it should theoretically fail datatype casting).

I have an application which connect to oracle db.
I have two database hitting functions.
One is adding Userdetails(Fn Name : AddUserDtls) and another one adding address details(Fn name : AddAddresDtls) based on UserName which will get added after execution of first method ie AddUserDtls.
Problem I am facing is :
I have a single transaction and in that I have all the methods.
After the execution of first method,with out commiting i will go to second method.
and if any error occurs in second method.
I will rollback everything including the changes made by first method also.
Here one issue is there.
Since I am not committing the changes made by first method,
While I am executing the second method I am getting error that 'No user Name exists'
I understood that if we commit the transaction before the second method starts ,it will solve the issue.
But then it creates another problem.If some problem araise in the second method,then I cannot rollback the changes made by first method since it aleready commited.

I am trying to delete three related objects on one submit. Delete fails on one of the child objects, because of foreign key contraint with another table, It deletes one (the parent) but not the two child objects. All in one SubmitChanges(). I even used the TransactionScope, still same thing. So here is the scenario:
I have an object called Page which has a collection of objects called Webinars. There is another object Called Product which is one to one with Webinar.

I have web app which stores certain things on a page in a cookie when the page posts back in case the user doesn't finish what they're doing and come back later. But now I must do a javascript time-out and actively save the info to the cookie rather than wait for the user to postback. All my cookie code is on server side where I use Response and Request objects to read and write cookies and I want to leverage that. So I would like to just use ajax calls to a webservice. Is there a way for me to access Request and Response objects and read and write cookies to the browser via those objects during a webservice call? Or should I just go with javascript?
EDIT: Sorry i wanted to specify that I would like to use jquery-ajax.

I am looking for an accepted pattern for using MVC 2 and EF. Especially I am interested on how to implement updates. Where should the ObjectContext be created, where should the queries be, how to pass a model object from the controller and have it persisted with minimum robust code. I also want to be able to use transactions when updating multiple objects.
I used Linq in an asp.net application (code behind model). With EF I was hearing it was much more n-tier friendly, but I don't find it any different, rather than people talking about POCO which to me, all it means is satisfying the desire of those that want to have control of every piece of code being created.

In my project's earlier version I used Stored Procedures (SPs) & directly used them inside presentation layer. SP contains multiple Insert & Update queries for multiple tables.
Now I have decided to use a DAL(Typed DataSets & TableAdapters)
How can i use the same SPs with TableAdapters or If not possible how to wrap Multiple TableAdapters inside Transactions.
1 more thing in my earlier version i was using Transaction in SPs & Presentation Layer.

We have a page that makes a request to a 3'rd party web service. When under heavy load this response time extends significantly, however the 3'rd party reports back that there times for processing remains constant. There timings show that from the time they receive a request to the time they send it back is always around 1.5-2.0 seconds. Now we are experiencing wait times of over 20 seconds. My understanding of ASP.NET is that each request will run on a IIS thread pool thread and make the request to the 3'rd party service return and process. So I don't really understand what could be blocking on our end. Is there something I am missing?? Is there a threshold limit beyond IIS that is blocking?
If I am missing something a physical book recommendation that covers this subject would also be a very welcome addition to any answer.

I'm writing some merge functionality in C# asp.NET MVC2. I am also using using Linq2SQL.
I have a block of code which calls two services, MessageService and UserService. These both in term call their appropriate repositories and make the amendments to the db. Each repository declares it's own instance of the repository so I'm thinking this will escalate the following code to DTC . The code is called from the AccountService, is this going to work at this level? And also is it bad practise to declare the DataContext at the top of every repository or should I pass the object around somehow?
//Run the merge
try
{
using (TransactionScope scope = new TransactionScope()) [code]....

I have an existing asp.net web application I am redesigning to use a service architecture. I have the beginnings of an WCF service which I am able to call and perform functions with no problems. As far as updating data, it all makes sense. For example, I have a button that says Submit Order, it sends the data to the service, which does the processing.
Here's my concern: If I have an ASP.NET page that shows me a list of orders (View Orders page), and at the top I have a bunch of drop down lists for order types, and other search criteria which is populated by querying different tables from the database (lookup tables, etc). I am hoping to eventually completely decouple the web application from the DB, and use data contracts to pass information between the BLL, the SOA, and the web app. With that said, how can I reduce the # of WCF calls needed to load my "View Orders" page? I would need to make 1 call get the list of orders, and 1 call for each drop down list, etc because those are populated by individual functions in my BLL.
Is it good architecture to create a web service method that returns back a specialized data contract that consists of everything you would need to display a View Orders page, in 1 shot? Something like this pseudocode:
public class ViewOrderPageDTO
{
public OrderDTO[] Orders { get; set; }[code].....
Or is it better practice in the page_load event to make 5 or 6 or even 15 individual calls to the SOA to get the data needed to load the page? Therefore, bypassing the need for specialized wcf methods or DTO's that conglomerate other DTO?

I have an ASP.NET page with two instances of the same Web User Control (a simple WYSIWYG editor). On submit, the WUCs do a little JavaScript magic and then proceed with a normal postback.
The first instance seems to be working, but the second fails to post changes back to the server (it reverts to the original, and posts that). I believe the problem is that the JS only fires for the first WUC. I've traced that to the following code, from the generated client-side source:
function WebForm_OnSubmit() {
prepHtml('AddEditPopup1_ctlEditorQuestion_txtEdit','AddEditPopup1_ctlEditorQuestion_divEdit', 'AddEditPopup1_ctlEditorQuestion_divHT' );
//snip...
}
The problem seems to be that there should be two calls to prepHtml: one for the ctlEditorQuestion instance of the WUC, and one for the ctlEditorAnswer instance.
Instead, there's only the one for ctlEditorQuestion. Both controls are registering the OnSubmit event, but one of them overwrites the other.The prepHtml call is registered from the WUCs' C# code at runtime:
//Page_Load
_onSubmit = String.Format("prepHtml('{0}','{1}', '{2}' );",
txtEdit.ClientID, divEdit.ClientID, divHT.ClientID);
//OnPreRender
Page.ClientScript.RegisterOnSubmitStatement(this.GetType(), "get-html", _onSubmit);
I should point out that I didn't write this control myself, and I've never seen this kind of runtime registration of OnSubmit JS code before. Page.ClientScript.RegisterOnSubmitStatement is totally new to me. I need to register both prepHtml calls so they run sequentially. Is this possible? I'm open to alternatives to Page.ClientScript.RegisterOnSubmitStatement, so long as the code still gets fired on submit.

I am trying to make 2 separate AJAX calls using buttons. What I want to happen is: when Button1 is clicked ProductsTable shows data from the webservice; when Button2 is clicked OthersTable shows its own data from the webservice. But right now, when either button is clicked, nothing shows up. I know the code works if there's only one of them and it's not wrapped around a .click function.
No error messages. ASP.NET 4.0, JQuery 1.4.4. Not using ScriptManager. Not using UpdatePanels.
Code below:

I need to gather information (via GET) from several other websites (not under my control), do some processing (specific to each source) on the data returned, and then print all the info out to the user.
Right now I'm making the GET request to website A, waiting for it to return, processing it, then calling website B, and so on... Obviously this is too damn slow. I'd like to make async requests to A, B, and C, then process each response as it comes back, and once I have all the responses, print it all out to the user.
I'm allowed to use classic asp or vb.net. I'm more familiar with classic asp but I'm willing to learn...

I know how to call a simple old fashion asmx webservice webthod that returns a single value as a function return result. But what if I want to return multiple output params? My current approach is to separate the params by a dividing character and parse them on teh client. Is there a better way.
Here's how I return a single function result. How do I return multiple output values?
<asp:ScriptManager ID="ScriptManager1" runat="server">
<Services>
<asp:ServiceReference Path="WebService.asmx" />

I have the following Page_Load function...
protected void Page_Load(object sender, EventArgs e)
{
XmlDataSource1.Data = GetXmlFromFile(Request.QueryString["file"]);
XmlDataSource1.DataBind();
Repeater1.DataBind();
}
The page in which this Page_Load resides is called by a parent page. Each time this Page_Load gets called the value of "file" in the query string will be different. So each time I will be receiving the XML contents from a different file which are inserted into the XmlDataSource and then bound against by the Repeater. Getting the XML data from the file works great but when I bind against the repeater that only works the first time through Page_Load. Each time after that when this code is executed the same results from the first XML file are displayed in the repeater.
What am I missing here. How can I get the XML data to be bound against the repeater on each page load instead of just the first one?
