Global.aspx, maybe I don't understand?

[Larry Bud]

Hi all. I have a webservice that calls a class, does some processing,
and returns some XML.

I would like to have a global exception handler to catch any misc
exceptions. From what I understand, I can create a global.aspx file
in my web service folder, add an Application_Error sub, and any system
exceptions will fire that off.

Right now I'm just setting the value of a local var so I can set a
breakpoint. An exception occurs in my app (a file not found
exception), but I get the raw exception message to the screen.
Application_error is never fired.

Is something wrote or am I totally misunderstanding the use of
Application_Error? I don't want to have catch/try through the
application...

Hello Larry,

Could you set breakpoints on Application_Start to verify that your global.aspx
works?

Application_Error needs to have code like:
Exception ex = Server.GetLastError().GetBaseException();
// do whatever you want with ex here

Shouldn't the name be Global.asax and not Global.aspx?

Hello Scott,

Yep, I just mistyped.
That's why I asked about Application_Start breakpoint.
It seems that global.asax dont get any requests, because it's probably ASPX
not ASAX

Yep, Application_Start is firing. BTW, it IS named global.asax, just
a typo in the subject line.

Application_Error needs to have code like:
Exception ex = Server.GetLastError().GetBaseException();
// do whatever you want with ex here

It's never even executing Application_Error

 

[Larry Bud]

Yep, Application_Start is firing.  BTW, it IS named global.asax, just
a typo in the subject line.- Hide quoted text -

Also, would the fact that this be a web service matter at all?

OK, another update. I changed the reference to the codebehind in the
ASMX for testing purposes, and it kicked off Application_Error.

But, it didn't get kicked off when a System.IO.Exception was kicked
off in some of the codebehind (a file not found when trying to open
error).

All errors are to be caught with Application_Error, right?

Hello Scott,

Yep, I just mistyped.
That's why I asked about Application_Start breakpoint.
It seems that global.asax dont get any requests, because it's probably ASPX
not ASAX

Michael, any other ides? The file is asax...

 

[George Ter-Saakov]

2 things..

1. Folder is not configured as an Application in IIS Management console.
2. Possible exception happens that prevents successful completion of
execution of the Application_Start hence it looks like it was not called.
The problem is that there is no visual confirmation that Application_Start
threw an error. Check NT event log. There will be a record there.
