Firewall or lack of direct connection to the Internet? It can be safely ignored if you don't need XML validation. Presumably, you have enabled validation because you actually want validation, so you should probably fix this. On another note, some Schema documents in their original locations may be quite slow to download. You might want to figure out how to plug-into the XML catalog mechanism Tomcat (hopefully!) uses to validate various XML documents it knows about (e.g. web.xml, etc.). Otherwise, you may find that deploying your webapp takes a long time just due to network lag. > Any advice / help would be greatly appreciated.
