How to pass through our proxy in java ?
Rush Woo
I have a problem when coding jsp program.
My computer which installed MS Proxy Client 2.0 is behind a firewall
which is running MS Proxy on Windows NT and authorization is base on
Windows NT domain account authorization,
My web server is apache 1.3.9 for winNT with JRun 4.0(using jre 1.2).
I have writen a JSP program like the list, it works well if the URL is
a site in my local network, but when the URL has been changed to
a site of Internet, just like the listed source, I get the error message,
Please tell me how to pass through our proxy in jsp?
Please response by e-mails. rus...@hengsys.com.cn
OR post answer in this news group.
Thanx!
here is the error message returned by JRun :
