You mean that in HTML file I should remove servlet?
Is this web.xml file correct?
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
"http://java.sun.com/j2ee/dtds/web-app_2_2.dtd";>
<web-app>
<display-name>Viewer</display-name>
<jsp-property-group>
<url-pattern>/jsp/Viewer/*.jsp</url-pattern>
</jsp-property-group>
<jsp-config>
<taglib>
<taglib-uri>http://java.sun.com/jstl/core-rt</taglib-uri>
<taglib-location>/WEB-INF/c-rt.tld</taglib-location>
