Hello, I forgot to mention that this error happens on linux (windows is OK),
and the "xr" variable is declared like DocumentBuilder xr = DocumentBuilderFactory.newInstance().newDocumentBuilder(); Thank you, kind regards,Nareg Garabedian --------------- Prevoius message------------- Hello, I'm having a problem while using a tomcat deployed application over https. http browsing though will run flawlessly. An error occures on parsing struts.xml The message is the following "java.net.UnknownHostException: struts.apache.org" The faulty line is nothing but Document d = xr.parse(inputStream); which I have used a million times without problems. I'd be grateful if anyone could help me to find the reason of such a behaviour. If more information is needed pls let me know. Thank you, kind regards, Nareg Garabedian
