kako se kreira Web.xml fajl

Sta sve treba da stoji u ovom fajlu. da li neko moze da mi napise kratko uputstvo?

Evo jednog primera web.xml za aplikaciju kreiranu u Spring frameworku. Mislim da ce ti biti jasnije.

<?xml version="1.0" encoding="UTF-8"?>

Ukoliko koristis neki IDE sa podrskom za J2EE, on ce ti automatski generisati ovaj fajl, pa mozes i tako da vidis..

Iskoristi onaj koji je dat kao primer u webapps/WEB-INF folderu. Naći ćeš ga u matičnom folderu gde si instalirao tomcat. Na Windowsu je to uobičajeno "Program FilesApache Software FoundationTomcat <verzija>". U svakom slučaju, za osnovnu upotrebu su ti dovoljni tagovi <servlet> i <servlet-mapping>. Imaš detaljno sve objašnjeno u Tomcatovoj dokumentaciji.
