attributes of the element web-app?
I downloaded Sun's DTD from here:
http://java.sun.com/dtd/web-app_2_3.dtd
After cleaning it up (just making it readable linebreaks) I was scanning through it to see what some of the attrributes are for the element web-app. According to this:
<!ELEMENT web-app (icon?, display-name?, description?, distributable?,
context-param*, filter*, filter-mapping*, listener*, servlet*,
servlet-mapping*, session-config?, mime-mapping*, welcome-file-list?,
error-page*, taglib*, resource-env-ref*, resource-ref*, security-constraint*,
login-config?, security-role*, env-entry*, ejb-ref*, ejb-local-ref*)>
one of the attrributes of this element is icon which can be 0 or 1 instance. So I put this in like so:
<web-app>
<display-name>Welcome to My JSP-Files</display-name>
<description>
Welcome to My JSPs
</description>
<icon>cl6D11.ico</icon>
</web-app>
and put the icon c16D11.ico in the same folder as web.xml namely WEB-INF. (I don't think the order matters???)
Assuming the dtd is well formed (the icon element is set up correctly in the dtd) I expected to see the icon in the Manager for my Tomcat 4.1.29. But I didn't for the Webapp that corresponds to Welcome to My JSPs. What did I do wrong? I restarted Tomcat but nothing no icon.

Yeah man I don't keep my "direction" intact often. Yes it is not in the XML I want to show the icon but in the manager. Silly me. And by golly I still had the order incorrect. OK I changed the order correct this time:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<icon>cl6D11.gif</icon>
<display-name>Welcome to My JSP-Files</display-name>
<description>
Welcome to My JSPs
</description>
</web-app>
jeeze!!!
OK let's see if it works now...

Huh? This isn't up to Tomcat. Tomcat follows the spec for web.xml. Other
configuration files are proprietary. Each spec up to and including the 2.3
spec used a dtd. 2.4 uses XML Schema.

Yeah I kind of think so too. I believe for this to work a XSL stylesheet is necessary for the generated Manager html. You know:
<!ELEMENT web-app (icon?, display-name?, description?, distributable?,
context-param*, filter*, filter-mapping*, listener*, servlet*,
servlet-mapping*, session-config?, mime-mapping*, welcome-file-list?,
error-page*, taglib*, resource-env-ref*, resource-ref*, security-constraint*,
login-config?, security-role*, env-entry*, ejb-ref*, ejb-local-ref*)>
everything here is "optional."
Moving off this dtd issue. Do you know if Tomacat ever intends going the schema route away from the dtd route? Thanks. Any links you could suggest on Tomcat's use of the dtd in its XML usage?

No still didn't work. Oh well I have the icon in the root of the webapp maybe what I'm expecting is not what this really does. I just assumed the icon would display in the manager as display-name and description do. One other thing I have no war in this application. At least none that I know of. I made this "virtual root" by myself under IIS Inet pub. I sort of just popped the web.xml in a WEB-INF folder I made and set up all this to work on port 80. The manager is still 8080 but the web app "can" be accessed over port 80.

Right, so you have an error in the order. A webapp is "optionally an
icon element, optionally a display-name, optionally a
description..",etc, etc.
You have Description, then icon.

This sounds like you're 'embedding' an image in XML? (I'm not sure
what you mean by "to appear in XML"). Tomcat only uses the filename,
and tries to find that icon file, as Tim pointed out,
"The file
name is a relative path within the web application's
war file."
So the file named in the 'icon' element is used, if found, by the
deployer(or not) it wouldn't look inside the XML itself for the icon.
(would it??) Have I totally misunderstood this last bit ?

The dtd is:
<!ELEMENT web-app (icon?, display-name?, description?, distributable?,
context-param*, ...
I was thinking the same thing the order that's why I changed it from my original post to the one above. I'm going to have to investigate the ATTLIST I may need a attributes on the child element <icon>. I can tell you getting images to appear in XML is tricky business. I have done it but using a XSL. I do have an XML that does it natively so I'll look more into that. Right now I don't think the dtd is constructed correctly for the image. At least it dosen't have the type of elements contructed in a dtd to do it as far as I can tell.

I'm surprised you didn't get some kind of error in the logs. DTDs also
require a specific order to the elements. You appear to have put your
icon element at the end when the DTD snippet you quoted clearly requires
it at the beginning. Try it at the beginning and see what you get.

Re: attributes of the element web-app?
Posted by Tim Funk <fu...@joedog.org>.
The dtd also says:
<!--
The small-icon element contains the name of a file
containing a small (16 x 16) icon image. The file
name is a relative path within the web application’s
war file.
The image may be either in the JPEG or GIF format.
The icon can be used by tools.
Used in: icon
Example:
<small-icon>employee-service-icon16x16.jpg</small-icon>
-->
So *if* tomcat shows the icon (which isn't required so I can;t recall if it
does) - the example above would look for the icon at:
mywebapproot/employee-service-icon16x16.jpg
