Problem with overriding parameters via context.xml

All,

I appear to have an issue with tomcat 6.0.30 not allowed web.xml parameters
to be over-ridden via context.xml file entries. This works fine in tomcat
6.0.29.

I have a parameter defined in web.xml, like this

<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
         version="2.4">

    <context-param>
        <param-name>log4jConfigLocation</param-name>
        <param-value>WEB-INF/classes/log4j.dev.xml</param-value>
    </context-param>

Then in context.xml I wish to override this parameter in different
deployment environments. So I create a context.xml file in
catalina_base\conf\context.xml containing the following

<?xml version='1.0' encoding='utf-8'?>
<Context>
    <Parameter name="log4jConfigLocation"
value="WEB-INF/classes/log4j.uat.xml" override="false"/>
</Context>

I then have a jsp file that contains the following

<%@ page contentType="text/html; charset=UTF-8" %>
<html>
<body>
<br>log4jConfigLocation is : ${initParam.log4jConfigLocation}
</body>
</html>

Using 6.0.29 the jsp shows the value present in the context.xml file, e.g.
expected behaviour. In 6.0.30 the value from the web.xml file is shown, e.g.
the required override hasn't happened.

I have read the release notes, and can't see anything that jumps out to me
saying that this behaviour has changed. Is this a defect in tomcat, or a
desired change or behaviour? If the latter, can anyone provide any pointers
as to how I can achieve my stated goal? My only current work around is to
revert to 6.0.29

Thanks

Chris

I plan to test with Tomcat 7, but some apps did not work well with the beta 
versions (IIRC because of using incorrect URL mappings that did work in Tomcat 
6).

What's wrong with 7.0.9? I am in the processing of uploading the files
for the release vote now. The ASF Jira instance has been happily running
7.0.x since 7.0.6 was announced as stable.

Ouch. 50700 is an absolute blocker for me. I'm stuck with 6.0.29 because of 
this, and having a useable release with the numerous fixes from 6.0.30 would 
be good.

7.0.9 probably in the next few weeks. I have been trying to stick to a
release every month or so.

6.0.33 is likely to be several months away. I don't see anything in the
change log that is likely to prompt an earlier release.

Oliver said that the defect I was asking about was 50700. This appears to
have been fixed now. So when is the next release of tomcat scheduled? I
searched the tomcat pages, but can't see a page listing anticipated launch
dates. I know open source projects don't tend to be so rigid, but is there a
date penciled in?

Thanks

Hi,

This looks like a symptom of this:

Bug 50700 – Context parameters are being overridden with parameters from the
web application deployment descriptor
https://issues.apache.org/bugzilla/show_bug.cgi?id=50700

Please vote for this bug and/or provide additional information in the bug
comments.

cheers
Oliver

Chuck,

Thanks for your quick response. I have tried placing the context.xml file in
the location you suggested and no change.

I didn't mention in m original post, but our context.xml also contains
resource definitions to connect to the database/smtp server. These settings
are being picked up fine - its just the parameters that seem to have changed
behaviour moving from 6.0.29 to 6.0.30

Thanks

Chris

That could be a problem.  The context.xml file in the conf directory is the global one, containing the default settings for _all_ webapps.  It would be better (perhaps required) to place the specific attributes in the <Context> element for the webapp of interest, either in the webapp's META-INF/context.xml file, or in conf/Catalina/[host]/[appName].xml.
