Hi Scott,
The proxy's Address is asked to the user via a dialog and the Information
are then stored as properties in a file.
the proxy-information is set to soap with something like this
st.setProxyHost(proxyHost);
st.setProxyPort(Integer.parseInt(proxyPort));
SOAPContext ctx = new SOAPContext();
ctx.setGzip(true);
Call call = new Call("urn:Bestterm",
callName,
params,
null,
Constants.NS_URI_SOAP_ENC,
ctx
);
call.setSOAPTransport(st);
...
The Dialog pops up when there is a Soap-Exception with the Message
something like this
catch (SOAPException sEx)
{
if ( sEx.getMessage().indexOf("Error opening
socket:")>-1
||sEx.getMessage().indexOf("Connection
refused:")>-1)
.... popup Dialog an get proxy infos
}//end of catch (SOAPException sEx)
In the traces I see that the Proxy-properties are set, so I suppose that
they are set.
for detail I send the class, which manages all the soap calls, as
attachment.
thanks in advance
Malte

Betreff: Re: Problem with Host-connection in combination with some
Proxies
"No route to host" typically means that the host is being connected
to without using a proxy, and the firewall is blocking the connection
attempt. How does your app determine their is a proxy?
