Why do I get the error: SAX parser fatal error: External entity not found: "http://java.sun.com/dtd/web-app_2_3.dtd"?

Benoit Quintin

[This happens because Sun's Web site is down, so the servlet engine can't find the remote copy of the web.xml DTD at that URL.]

Well, you can download the dtd and point the document reference inside web.xml to the local copy, I suppose.

[You can also "inline" the DTD by replacing the reference with the literal text of the DTD. See this web.xml file for an example.

Finally, you could attempt to turn off DTD validation in the XML parser, but not all servlet engines allow you to configure the XML parser they use to parse web.xml.
