[ANN] Apache Tomcat Connectors 1.2.49 released
The Apache Tomcat Connectors project is part of the Tomcat project and provides web server plugins for httpd (mod_jk) and IIS (ISAPI) to connect those web servers with Tomcat and other backends. The Apache Tomcat Project is proud to announce the release of version 1.2.49 of the Apache Tomcat Connectors. This version fixes a number of bugs found in previous releases. Full details of these changes and new features, are available in the Apache Tomcat Connectors changelog: https://tomcat.apache.org/connectors-doc/miscellaneous/changelog.html In addition to the usual source release, this release includes Windows binaries for the JK ISAPI connector for IIS. Downloads: https://tomcat.apache.org/download-connectors.cgi Thank you, -- The Apache Tomcat Team - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Where do find debug logging
We have some applications which are pushing out to their own applogs clearly showing 'Debug' on most lines with a large amount of data and CI. I would like to find out where the app team are setting this level, I have check in the obvious in the war files as it's a Spring Boot app in application.properties and logback.xml but mention error only there. Any advice appreciated thanks

How have you configured your JSP(s) to use this alternative base class?
sudo cat /usr/local/apache-tomcat-9.0/webapps/tlaitc-dashboard-1a1/index.jsp
<%@page extends="dashboard.web.pages.BasePage"%>
hi x is ${x}
Output shown in log (sorry for not including the JSP the first time)
but to make it easier to find the output is "hi x is " when it should
be "hi x is 123234"... as you notice there are zero errors/warning in
catalina but there is none of the println's also... so the only thing

syntextual errors [including the contents of the string literal] will

Your _jspService method in your base class will never be called, because
it is overridden by the auto-generated class for your JSP, which does
not call super._jspService.
I do not believe that this:
Hi X is ${x}
...will result in this.getX() being called from the JSP. References in
EL ${...} expressions will be resolved against the PageContext (and
other wider contexts), not against the JSP class currently executing.
If you want to call this.getX() then you will need to do this:
Hi X is <% getX() %>
I wouldn't bother messing-around with class hierarchies in JSP. It
usually doesn't get you much but almost always requires you to bind
yourself very closely with the specific implementation of the JSP engine.
It would be far better to use typical MVC-style development where a
servlet (or similar) handles the real work of the request, possibly
including writing a value of "x" to the request attributes. Then forward
your request to your JSP to produce the response content. This will be
much more straightforward and you will have fewer problems like this,
where expected behavior is confused by all the magic that JSP provides.
Thanks but I have a very specific use case which the following working
example below should make more clear:
<%@page import="dashboard.web.page.Page"%>
<%
// THIS WOULD NOT BE NEEDED if <%@page extends="..."%> worked
//
// for now we don't need to keep the page object just
// the setAttributes in our ctx
new Page(pageContext);
%>
<%@include file="/widgets/scripts/scripts.jsp"%>
and the Page class:
package dashboard.web.page;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.jsp.PageContext;
import org.petitecloud.util.PetiteCloudNullException;
// making this extend the right subclass plus working page
extends="" would mean zero in-line Java
// Copyright (C) 2023 TLAITC and contributors
public class Page
{
public Page(PageContext ctx)
{
_dbc_construction(ctx);
this.ctx=ctx;
HttpServletRequest req=(HttpServletRequest) ctx.getRequest();
String[] parts=req.getRequestURI().split("/");
int split=2;
if(parts[0].equals("http:"))
split+=2;
name="";
for(int i=split;i
<%@page extends="dashboard.web.page.Page"%>
<%@include file="/widgets/scripts/scripts.jsp"%>
Side note I am currently adding user detection to the above page class
to that it can auto-enforce ACL's
I'm not sure I understand the point of the whole exercise. Nothing you
have in the PageContext class constructor cannot be done from within the
JSP itself, or -- better yet -- in an <%include> used by as many pages
as you want. *OR* ... you could do it in a Filter and apply it to all
requests, storing the information in the request attributes, which is
much more standard than directly modifying the page context.
The idea is to avoid any custom entries in web.xml (which filters
require)
This is not entirely true, and seems to be an arbitrary requirement. The
application is configured via web.xml. Why disallow any configuration in
web.xml?
and the entire point is this is a top level template and
future versions will provide a number of standard setAttriburtes that
expose different things like the logged in user.
Yeah, you are welcome to your own opinion, but everything you describe
sounds like "we want to use JSPs for everything and not write Java code"
and honestly what you
