hey,

i've got a webservice with one webmethod. if an exception occurs in this method, i'd like to throw it (and transport it back to the client) as a SoapException. my code looks somewhat like this:

[WebMethod]
public News[] GetLatestNews(string subscriberKey, int count, string languageName)
{
 try {
  // do something that throws an exception
 }
 catch (Exception ex)
 {
  string msg = "Internal Server Error: " + ex.Message;
  string actor = HttpContext.Current.Request.Url.AbsoluteUri;
  XmlNode details = BuildDetails(actor, ERR_SERVERERROR, msg);

  throw new SoapException(msg, SoapException.ServerFaultCode, actor, details);
 }
}

the method BuildDetails creates an XmlNode with some error information (as you can probably guess by looking at the signature).

my problem is: when i start debugging the webservice, the page i get when i invoke the method shows only the error message. without any xml around it. but i'd like to have a proper xml-return which contains all of the information i've placed into the SoapException.

what am I missing here? thanks in advance.

I haven't used a soapException before, but often in my webservices I pass out a ref string error. If it is not blank then I got an error. That seems to have worked pretty good for me.

Looks at the documentation, like I said before I haven't used soapexception. It seems that the xml is only there if you put it there.

public class ThrowSoapException : WebService 
{
//    This XML Web service method generates a SOAP Client Fault code 
    [WebMethod]
    public void myThrow(){

        // Build the detail element of the SOAP fault.
        System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
        System.Xml.XmlNode node = doc.CreateNode(XmlNodeType.Element, SoapException.DetailElementName.Name, SoapException.DetailElementName.Namespace);


        // Build specific details for the SoapException.
        // Add first child of detail XML element.
        System.Xml.XmlNode details = doc.CreateNode(XmlNodeType.Element, "mySpecialInfo1", "http://tempuri.org/");
        System.Xml.XmlNode detailsChild = doc.CreateNode(XmlNodeType.Element, "childOfSpecialInfo", "http://tempuri.org/");
        details.AppendChild(detailsChild);

            
        // Add second child of detail XML element with an attribute.
        System.Xml.XmlNode details2 = doc.CreateNode(XmlNodeType.Element, "mySpecialInfo2", "http://tempuri.org/");
        XmlAttribute attr = doc.CreateAttribute("t", "attrName", "http://tempuri.org/");
        attr.Value = "attrValue";
        details2.Attributes.Append(attr);

        // Append the two child elements to the detail node.
        node.AppendChild(details);
        node.AppendChild(details2);

            
        //Throw the exception.    
        SoapException se = new SoapException("Fault occurred", SoapException.ClientFaultCode,Context.Request.Url.AbsoluteUri,node);

        throw se;
        return;    }
}

hey kubben,

thanks for your reply. yes, i knew this already. but i've copy-pasted your code above into my project, just in case i missed something. the same result. the only return i get is the literal: "Fault occurred".

i need to return a properly formatted soap response with a couple of details concerning the error? i was already wondering, if IE is "eating" the soap message and reducing it to this simple string. but it seems my IE settings are ok.

kind regards

You know looking at the overloads for the create of the soapException, I can find one that matches what you are passing in. I am thinking perhaps that is the problem? The only overloads with four parameters are:

public SoapException (
	string message,
	XmlQualifiedName code,
	string actor,
	XmlNode detail
)
public SoapException (
	string message,
	XmlQualifiedName code,
	string actor,
	Exception innerException
)

So I think that is where you need to look.

Ben

matthias s.22-Aug-07 3:46

22-Aug-07 3:46

but the first one matches the code i've posted:

throw new SoapException(msg, SoapException.ServerFaultCode, actor, details);

I think that SoapException.ServerFaulCode is not a XmlQualifiedName.

An XML qualified name is a namespace qualified local name in the format of namespace:localname.

Because prefixes are only required when XML is persisted or read, they are irrelevant for XmlQualifiedName objects. This class assumes that prefixes are irrelevant. It is the responsibility of the user to ensure the local name does not contain a ":".

I found this link:
http://www.developer.com/net/csharp/article.php/10918_3088231_1[^]

The only real different between what that article has seems to be the uri they are passing in. Anyway, sorry I haven't been much help.

Hi,
My requiremnt is that I need to update my website with live update of events and alarms . The events can go up to 250 numbers per second. I have an idea that Ajax Push can be used for the live update of events. Can anyone explain me how it can be done ?

Can any system handle such a magnitude of events?

Hi everyone,

Could you please show me how to change server system datetime using ASP code?

Thanks in advance.

Do you mean change the locale / default date format from, say dd/mm/yyyy to mm/dd/yyyy ? You can't - you cannot change a person's server settings from an asp application, thank god! Imagine if every asp application you ran changed your computer's settings! You wouldn't know where you stood from one minute to the next, let alone the damage that could cause.

You can format the datetime values within an application using the VBScript FormatDateTime function (classic ASP) or the ToString function in .NET

Why won't this work in Firefox or Netscape?

This code will work in IE6 but not in Firefox or Netscape. I believe that the event.clientX is the problem but I am not sure how to fix it. Any ideas? I know I am just over looking something.

<br />
// JScript File<br />
//<br />
//<br />
//Class constructor--> Popup div tag<br />
function newPopup(current)<br />
{<br />
    //class variables<br />
    this.idName = current + "popup";<br />
    this.text = "Click here.";<br />
    this.browser = navigator.appName;<br />
    //class methods and functions<br />
    this.displayPopup = display;<br />
}<br />
//<br />
//<br />
//Class Method displays the div tag on the html document<br />
function display()<br />
{<br />
    document.write("<div id='" + this.idName + "' class='popup'>");<br />
    document.write("<div class='subPopup'>" + this.text + "</div>");<br />
    document.write("</div>");<br />
}<br />
//<br />
//<br />
//Mouse Over Event --> add this function to a tag's onmouseover and<br />
//onmousemove events<br />
function showPopup(current)<br />
{<br />
    var id;<br />
    var x;<br />
    var y;<br />
    //<br />
    id = current + "popup";<br />
    x = event.clientX + top.document.body.scrollLeft;<br />
    y = event.clientY + top.document.body.scrollTop - 40;<br />
    //<br />
    top.document.getElementById(id).style.display = "block";<br />
    top.document.getElementById(id).style.left = x + "px";<br />
    top.document.getElementById(id).style.top = y + "px";<br />
}<br />
//<br />
//<br />
//Mouse Out Event --> add this function to a tag's mouseout event<br />
function hidePopup(current)<br />
{<br />
    var id;<br />
    id = current + "popup";<br />
    top.document.getElementById(id).style.display = "none";<br />

Can you provide the whole codes (including HTML) that you said it's working in IE?

I will try to reproduce in Firefox and will let you know the result.

top? are you using frame?

Try the code below ~

function showPopup(current,evt)<br />
    {<br />
    var id;<br />
    var x;<br />
    var y;<br />
    //<br />
    id = current + "popup";<br />
    if(window.event){<br />
      x = event.clientX + top.document.body.scrollLeft;<br />
      y = event.clientY + top.document.body.scrollTop - 40;<br />
    }<br />
    else{<br />
      var e = (window.event) ? window.event : evt;      <br />
      if(e != null){<br />
         x = e.clientX + top.document.body.scrollLeft;<br />
         y = e.clientY + top.document.body.scrollTop - 40;  <br />
      }<br />
    }<br />
    //<br />
    top.document.getElementById(id).style.display = "block";<br />
    <br />
    if((x == 'NaN') || (y == 'NaN')){<br />
        top.document.getElementById(id).style.left = x + "px";<br />
        top.document.getElementById(id).style.top = y + "px";<br />
    }<br />
