what do you mean "real syntax" ???
XML syntax is up to you, as long as you have starter and a closing tag, special meaning for the element you created. i think something like this:
<my-name>Nicky Eng</my-name>
where <my-name> is the descriptor to descript the element i specified for. And </my-name> is to close the <my-name>.
about web.xml somewhere under
Tomcat directory, the <web-app....something here...> i still exploring the HFSJ books...
hope other member can provide you and me with more specified details of web.xml stuff.....
all the best...
