info: CORE3282: stdout: PARSE error at line 108 column -1
info: CORE3282: stdout: org.xml.sax.SAXParseException: Element "web-app" does not allow "filter" here.
failure: ContextConfig[simple] WEB3524: Parse error in application web.xml
org.xml.sax.SAXParseException: Element "web-app" does not allow "filter" here.

if I change as you said
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
line with
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
then it's not loading the application
pls suggest me
