Hi,
I am creating a windows service..
in that i am connecitng to a webservice and retrieving the data by
calling a web method. This calling will be done every 5 min once and
the data will be stored in the database.

I added a web reference.. successfully.
proxy class generated..
installed as windows service
I am getting error when It connecting webservice and calling web
method.

But when I work with same in Normal windows application.. I am
successfully connecting to the webservice and able to call web method.

Working in Web application also successfully.

GIVING PROBLEM ONLY IN WINDOWS SERVICE .

The following is the class having Single method. "CallWebservice()"
which I am calling
==================================================================
public class TestClass
{
ILogManager log = LogManager.Instance;

public void CallWebservice()
{
log.Log(LogTypeEnum.INFO, "Starting windows service
calling..............!");
MgmtServicesSoap mgmtServiceProxy = new MgmtServicesSoap
();
try
{
log.Log(LogTypeEnum.INFO, "Connecting to webserice for
tesing..");
mgmtServiceProxy.PreAuthenticate = true;
mgmtServiceProxy.AllowAutoRedirect = true;
mgmtServiceProxy.Proxy = WebRequest.DefaultWebProxy;

NetworkCredential networkCredential = new
NetworkCredential("xxxxx", "xxxxxx");
CredentialCache credentialCache = new CredentialCache
();
credentialCache.Add(new Uri(mgmtServiceProxy.Url),
"Basic", networkCredential);
mgmtServiceProxy.Credentials = credentialCache;

log.Log(LogTypeEnum.INFO, "Proxy class initialized.");
string responseXmlString =
mgmtServiceProxy.getTransactionStatus("143566");
log.Log(LogTypeEnum.INFO, "Proxy class initialized
succesfully and connected to webservice.");
log.Log(LogTypeEnum.INFO, responseXmlString);

}
catch (Exception ex)
{
log.Log(LogTypeEnum.ERROR, "Error occured while
connecting to the webservice.");
log.Log(ex);
}
}

}

=====================
Windows service startup code
======================
protected override void OnStart(string[] args)
{
log.Log(LogTypeEnum.INFO, "Starting windows
service..............!");
MgmtServicesSoap mgmtServiceProxy = new MgmtServicesSoap
();
try
{
TestClass ss = new TestClass();
ss.CallWebservice();
}
catch (Exception ex)
{
log.Log(LogTypeEnum.ERROR, "Error occured while
connecting to the webservice.");
log.Log(ex);
}
}

Is it possible that the account the service is running under simply doesn't
have network access?

The above kind of seems that you may be having a firewall issuse (blocked
port) as something is happening with TCP port 443, the HTTPS port.

Is all this you're talking about happening on the localhost/machine or a
remote IP/machine?
 
Hi
Thanks for the reply..

As you said there might be firewall issue.. Or port 443 issue..
It working fine in the Windows application without any problem. I am
receiving response what I expected (correct one).

In windows forms I added reference of the window service project and
called class.. as like an button click I did like this.

try
{
TestClass ss = new TestClass();
ss.CallWebservice();
}
catch (Exception ex)
{
log.Log(LogTypeEnum.ERROR, "Error occured while
connecting to the webservice.");
log.Log(ex);
}

It works fine without any problem... When it is working fine the same
why it is not working in the windows service....

Help to get out of this issue...

thanks

What happens when you try to consume the Web service in a Console
Application that is the Web client? And how is port 443 involved? Do you
know that you are using HTTPS for the Web service? Is this Web service being
consumed on localhost/IIS running this Web service or is the Web service
being consumed over HTTP a Internet or Intranet solution on a remote Web
server?
 
Hi Arnold

Thanks
As you said.. Console I didn't try..
The webservice I am consuming is developed using JAVA.
This webservice hosted some other remote machine, not in local machine
IIS.
It is consumed over internet.. not Intranet
I will try with console application ... .

thanks

Well, I can see the HTTPS TCP port 443 coming into play here possibly on
a remote Web server and a Web service that's using HTTPS, because the
error message you have provided is talking about TCP 443 the HTTPS port.

I don't know what trying to do here, as I am not privileged to the
information that you have. But if this is a 3rd party vendor Web
service, then you need to be in contact with the 3rd party vendor about
the consumption of the Web service from your Web service client solution
via a Windows desktop, ASP.Net, Windows service or Console application.
 
Hi Ollis

As you said I am tring to connect third party webservice developed in
Java..

One thing I am still in doubt.. why it is not working only in
WindowService, it is working in asp.net web application & C# Windows
application.

The exception/Error comming only When I am trying to connect in
Windows Service...?

Can you help me on this issue?

thanks

Hi
Thanks for all for your support
I am able to find out the solution

I changed the proxy settings like this..
from
mgmtServiceProxy.Proxy = WebRequest.DefaultWebProxy; (giving
error, But is the wrong )
to
mgmtServiceProxy.Proxy = new WebProxy("10.108.26.212", 80);

Or can be used

<system.net>
<defaultProxy>
<proxy
proxyaddress = "http://10.108.26.212:80"/>
</defaultProxy>
</system.net>


thanks
