My application owner try to get a html page to be attach to his email. Sometime, he got the page but sometime could not. He encounter "Unknown host exception" when hit the problem. Sample of the code use for getting the url & sending it via email: URL urlObj = new URL(url); URLConnection urlConn = urlObj.openConnection(); BufferedReader in = new BufferedReader(new InputStreamReader(urlConn.getInputStream())); StringBuffer sb = new StringBuffer(); Thanks for any help.

your code looks like java. anyway. throwing an "unkown host exception" has the following reason: "Thrown to indicate that the IP address of a host could not be determined." (from java.net API ) try to prompt the hostname from within your application in System.out. if you know the hostname you could ping the server by its name. if this doesn't work, you could add the hostname and it's IP to a file called hosts (on LINUX and Windwows machines). LINUX: /etc/hosts WIN: [WINHOME}\system32\drivers\etc\hosts
