Posts: n/a
Hi Mr. Dino

Thank you very much for responding
I am using VS.NET 2003 only.
I am able to access otherwebservice hosted on internet. (samples ...)

Previously I was unable to access the above webservice probably due to
your reason being i was using VS.NET 2002.
Now, i faced no problem in accessing in above webservices, all are
working fine.

I am able to access the webserivce through java client which is
developed by us.
When the reference file is generated the port info is given as

public JDASWS() {
this.Url =;

where the webservice is running actually at port 8080.
The code I have written to access the webmethod say (login) is ...

com.fusiontech.dti.JDASWS jdasws = new com.fusiontech.dti.JDASWS();
jdasws.Timeout = -1;

If the time out is not set to -1, the its saying "operation timed out",
otherwise the error message is ...

"An unhandled exception of type 'System.Net.WebException' occurred in
Additional information: The underlying connection was closed: An unexpected
error occurred on a receive."

If I change the port in reference.cs to 8080 (form 80) as,
The error occured is ..

"An unhandled exception of type 'System.Net.WebException' occurred in
Additional information: The request failed with HTTP status 502: Proxy Error
( The Uniform Resource Locator (URL) does not use a recognized protocol.
Either the protocol is not supported or the request was not typed correctly.
Confirm that a valid protocol is in use (for example, HTTP for a Web
request). )."

We don't have any proxy servers in between.

For your reference, i am giving java code too, please go through

com.dti.jdas.server.webservices.JDASWS_Impl jdasImpl =null;
com.dti.jdas.server.webservices.JDASInterface port=null;
com.dti.jdas.server.webservices.SessionResult sr=null;
try {
jdasImpl = new com.dti.jdas.server.webservices.JDASWS_Impl();
port = jdasImpl.getJDASInterfacePort();
sr =
(com.dti.jdas.server.webservices.SessionResult)por t.login2("john","john","De
catch(Exception e) {

Please help me in figuring out the exact problem, and suggest me a

Thanks & Best Regards
