View 2 RepliesNet 3.5 has lots of enhancements on secure and transacted webservices ? Does anyone here have experience of this ? does it add overhead ? Can these webservices (in a LAN environment and assumed stateless / lightweight) be relied upon to be used in realtime (by realtime I mean response of 1 second or less ?). I realise that this cannot be guaranteed as it depends heavilly on what the service is doing and what network it is deployed upon etc etc etc, but assuming there are no issues here, what I am simply asking is, is the benefit of 'knowing' your webservice will return impaired by any overhead that prevent such a webservice from being generally reliable enough to be used in a real time application ?

I am developing an ecommerce app that is using the UPS shipping webservice. I have read that it is good to create a singleton so there is only one instance of a webservice at any time. My code for that is below.

I'm having problems with parsing the XML results that a webservices is sending me. Mostly due to the format this result is sent in. I can succesfully send a request and I get the response back in a string. Now the (truncated) result looks like this:
- <tr>
<td field="fin.trs.line.dim2" hideforuser="false" type="String">01249</td>
<td field="fin.trs.line.openbasevaluesigned" hideforuser="false" type="Value">-100.00</td>

This is where my problem starts. Because I've found various pieces of code that let me take out the nodes I need. So in the above example <Office> and <code> come out perfectly. But the problem appears when reading the other lines because they start with <td SPACE field=> etc etc. When I readout those lines all I get back is TD.
I need to specifically filter the results based on those TR/TD fields. I'm using an XMLreader and xmlnodetype to filter out the results, but maybe I'm using the wrong method.
I've got the unenviable task of cleaning up a rather messy VB.Net client. The general plan is to move all calculations to WebServices, and I can see exactly how to do this, but it involves passing a large number of different variables to the WebServices. I chose to use an ArrayList as I've worked with them heavily in Java, and have had no issues passing ArrayLists between the C# (ASMX) WebService and a C# client (Windows Forms-based).

View 2 RepliesAm pretty new to web services and have been trying to implement Soap Faults. I used Apache Axis2 to generate webservice in the following manner.
[Code]
Now, I created a dynamic project using Eclipse and with the help of Axis2 plugin I created webservice for my "Webservice" class which generates wsdl file. I deployed the webcontent in the Tomcat folder and able to access the WSDL file in the .Net environment. I am able to pass array of objects (User[]) from .Net to Java and able to do my task. Now, I need to implement Soap Faults in Java which I am not sure how to implement.
I am calling Classic ASP Webservices from a .NET application. I have two instances of slow processing of the webservice and fast processing. The slow way (several seconds at the most) is where I actually read the data returned as such:
Dim oRequestAOCP As WebRequest
Dim oResponseAOCP As HttpWebResponse = Nothing
Dim dataStreamAOCP As Stream = Nothing
Dim readerAOCP As StreamReader = Nothing
[code]....
What can I do to speed things up when I need data returned?

View 1 RepliesI have a .net application that uses customerrors web.config module to display meaningful messages for errors. It works without any issues for 500 errors/exceptions caused by non-ajax and ajax components (updatepanel). However, in a scenario where updatepanel's asynchronous request times out, there is no error raised at all. I was able to see the timeout in firebug and come up with a solution that would at least display the error message as an alert and then redirect the user to the 500 error page using javascript but it's not quite doing what the rest of the application does in case of an unhandled errors like these. I basically just want everything to go through "LogEvent" mechanism so based on the severity of the error, it does the necessary work.This 500 error page doesn't have anything in the Server.GetLastError() for these timeout scenarios. Is this an expected behaviour? Can it be changed so I do have access to these timeouts in Server.GetLastError() OR maybe just run this error through "LogEvent" mechanism? Is there a better/more graceful way to handle this issue?
Below is my code to give you an idea, not exactly what I have in my application but pretty close.
Web.Config
<customErrors mode="On" defaultRedirect="~/Errors/ErrorUnknown.aspx" redirectMode="ResponseRewrite">
<error statusCode="500" redirect="~/Errors/Error500.aspx" />
</customErrors>

I have worked out how to pass my custom objects into ASP.Net json webservices. Works a charm. Problem I am having is passing in straight arrays of my custom objects or alternatively passing in arrays that are parameters of my custom objects. So for example...
Public Class WebService1
Inherits System.Web.Services.WebService
<WebMethod()> _
[code]....
Fails with error: The value "System.Collections.Generic.Dictionary`2[System.String,System.Object]" is not of type "WebApplication1.WebService1+Person" and cannot be used in this generic collection. Parameter name: value
So how do I explain to ASP.net that it is infact an array of Person? note: That changing the function to as List(of Person) or ArrayList does work but given that I implement my own custom collections this is not optimal for me.
UPDATE: Ok so what I have worked out so far is that this problem is definitely associated with how the JavascriptSerializer uses the SimpleTypeResolver to resolve types. Basically if I do something like this
Public Function AddPersonList(ByVal PersonList As String) As PersonList
I can recreate the error using the following code.
Dim PersonList As PersonList = jsonSerializer.Deserialize(Of PersonList)(PList)
However when I provide my own custom type resolver along the lines of
Dim jsonSerializer As New JavaScriptSerializer(New MyCustomTypeResolver)
I can successfully create an instance of my custom list.Now I have worked out how to provide my own custom convertor in the web.config file. Along the lines of this....
<system.web.extensions>
<scripting>
<webServices>
[code]....
PSS: I have tried to use the assembly fully qualified name as specified in the docs for the SimpleTypeResolver (SimpleTypeResolver MSDN) but this throws a "Operation is not valid due to the current state of the object." exception - which is an error caused when the TypeResolver cannot resolve the name?
My problem was never passing in a List(of Object) into my webservice (I simply posed the question as such to simplify it for stackoverflow). In such a case I would be willing to completely accept using a Generic List(of) but my problem was actually that one of my custom objects implemented a property with a strong typed List(of) so for example:
Customer {CustomerID AS Guid, FirstName AS String, LastName AS String, EmailAddresses AS EmailAddressList}
which now needs to be changed to
Customer {CustomerID AS Guid, FirstName AS String, LastName AS String, EmailAddresses AS List(Of EmailAddress)}
This is admittedly not the end of the world and is probably better in the webservice context (as you have suggested) but definitely a detriment when it comes to internal application usage of my Collection properties. What this means is that once I have this property I either need to cast it to my CustomCollectionList every time I want to use some advanced feature or I need to implement another property which exposes the CustomCollectionList.
I am trying to consume the webservice from the .Net environment which was build in Java environment. Currently am trying to forward the ArrayList of type object array as parameter to the WSDL file.Am experiencing the following error message : "There was an error generating the XML document"let me know the whether I need to manually convert the ArrayList to XML . May I know the best procedure to forward the ArrayList to webservice in Java ?

View 4 RepliesI currently have an application that uses the FileSystemWatcher object and events to monitor activity in a selected folder. this works great for detecting files being copied to or created in the folder, moved or deleted and changed, however, I am trying to determine if a file is accessed (opened) regardless of if it is modified. One of the NotifyFiler options is LastAccess. It appears that this fires an event, however, it always seems to be the Modified event. I would like to be able to keep track of file access and modification separately. I currently store the activity in a listbox and also in a richtextbox where the text color illustrates the type of activity.Does anyone know how to accomplish determination of file Access versus file Modification?I have included some of my FilesystemWatcher code below.
