java - I am using org.htmlparser.Parser to parse URL but its failing for external URLS and giving Connection Refused: connect error -

i using org.htmlparser.parser parse url, works fine internal urls in network. when try opening external urls, gives

exception in thread "main" org.htmlparser.util.parserexception: connection refused: connect; java.net.connectexception: connection refused: connect

this line failing -

parser p = new parser("http://www.google.com");

i can open external urls in browser using proxy. doing proxy authentication using authenticator class in code not working.

you might want set proxy connectivity parameters when run java program

java -dhttp.proxyhost=proxyhosturl      -dhttp.proxyport=proxyportnumber      -dhttp.proxyuser=someusername      -dhttp.proxypassword=somepassword javaclasstorun
