Can Tomcat 4.03 expire web pages
Hi;
My boss wants to "expire" our jsp pages.
In other words, if a user hits backspace, instead of getting the jsp
page s/he just left s/he would see a notice that the page expired.
I've seen snippets of code to do this on google, but I haven't been able
to get them to work.
Can Tomcat 4.03 "expire" web pages or do I need a webserver with Tomcat
to do this?
Also if someone could show me an example of how do this, with the
example of being a whole html/jsp page I would appreciate it.
Thanks in advance
Steve

Tomcat 4.03 CLI options?
Posted by Steve Russell <sr...@zeera.net>.
I did look through the docs.
Where can I find a list of command line options to use with
TOMCAT_HOME/bin/startup.sh ?
Thanks in advance

Re: Tomat 4.03 JAVACMD & Startup Properties
Posted by Steve Russell <sr...@zeera.net>.
Hi;
I'm using tomcat 4.03 and the IBM jdk 1.3.1
I'm running these commands to start my project
export JAVACMD="$JAVA_HOME/bin/java
-DprojectProperties=$PROJECT_HOME/conf/project.properties"
./startup.sh
This worked with tomcat 3, but with tomcat 4.03 when I check the
catalina.out log file it looks like it is not getting "projectProperties".
Does tomcat 4.03 pickup JAVACMD?

Tomat 4.03 As A Stand alone
Posted by Steve Russell <sr...@zeera.net>.
Hi;
I'm trying to convert a web app to tomcat 4.03.
I set up my project tree as recommended by the manual.
My top level directory is /zot
The other directories are:
/zot/build
/zot/doc
/zot/dist
/zot/src ( has net.mypackage under it )
/zot/WEB-INF
/zot/WEB-INF/classes ( has compiled *.class of net.mypackage under it)
/zot/web
/zot/web/js
/zot/web/common_jsp
/zot/web/jsp1
/zot/web/jsp2
/zot/web/css
/zot/web/js
I put this tag in my server.xml
<Context path="/zot" docBase="/zot/web" debug="0" reloadable="true"/>
When I try to go to either jsp1 or jsp2 ( two seperate collections of
jsps used as two differnt apps/sites) I get this error message:
============================
Apache Tomcat/4.0.3 - HTTP Status 500 - Internal Server Error
type Exception report
message Internal Server Error
description The server encountered an internal error (Internal Server
Error) that prevented it from fulfilling this request.
exception
java.lang.NullPointerException
at
org.apache.jsp.index_0005fhome$jsp._jspService(index_0005fhome$jsp.java:67)
at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:107)
================================
I'm stumped.
Any ideas or clues?
Thanks
Steve

I think so, partly. I don't want the user to be able to get that page
at all by backspacing....only a message that the page has "expired".

Re: no-cache where to set?
Posted by peter lin <pe...@labs.gte.com>.
In your jsp page, add the following code at the top.
<%
response.setHeader("Cache-Control","no-cache");
response.setHeader("Pragma","no-cache");
response.setDateHeader ("Expires", 0);
%>
for more info on no-cache, jguru has some useful stuff

set your pages to no-cache, which forces the browser to always get it
from the server. Is that what you're looking for?
