Thanks for the attached Oleg - I've made these changes to the application,
but I'm still experiencing the same error;
I/O exception (java.net.SocketException) caught when processing request:
Operation timed out: connect:could be due to invalid address
2ab52ab5 HttpMethodDir I org.apache.commons.httpclient.HttpMethodDirector
Retrying request
I've checked that the proxy server itself is OK by creating the connection
using Java.net.HttpURLConnection, and all appears to be OK. Do you have any
other suggestions as to where I may have gone wrong?
Thanks, Greg
