Answer 1

i am using "Apache Tomcat/5.0.28"
and all jsp are converted to servlet which extends org.apache.jasper.runtime.HttpJspBase which in turn extends javax.servlet.http.HttpServlet
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jasper/docs/api/org/apache/jasper/runtime/HttpJspBase.html
as my jsp (automatically converted servlet) is extending javax.servlet.http.HttpServlet, now i think getLastModified() should definitely get called.
one more thing i found is that when i override getLastModified() with int as return type, i am getting transalation time error as follow :
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 30 in the jsp file: /core.jsp
Generated servlet error:
D:\hasan\jakarta-tomcat-5028\work\Catalina\localhost\test\org\apache\jsp\core_jsp.java:12: getLastModified(javax.servlet.http.HttpServletRequest) in org.apache.jsp.core_jsp cannot override getLastModified(javax.servlet.http.HttpServletRequest) in javax.servlet.http.HttpServlet; attempting to use incompatible return type
found : int
required: long
public int getLastModified(HttpServletRequest req)
