Deployment choking on <filter> tag

[kjc5664]

JBoss deployer is choking on the following
filter mapping.


<servlet-name>ServletRedirector</servlet-name>
<servlet-class>
org.apache.cactus.server.ServletTestRedirector
</servlet-class>
<init-param>
<param-name>param1</param-name>
<param-value>value1 used for testing</param-value>
</init-param>



<servlet-name>ServletTestRunner</servlet-name>
<servlet-class>
org.apache.cactus.server.runner.ServletTestRunner
</servlet-class>


<servlet-mapping>
<servlet-name>ServletRedirector</servlet-name>
<url-pattern>/ServletRedirector</url-pattern>
</servlet-mapping>

<servlet-mapping>
<servlet-name>ServletTestRunner</servlet-name>
<url-pattern>/ServletTestRunner</url-pattern>
</servlet-mapping>


<filter-name>FilterRedirector</filter-name>
<filter-class>org.apache.cactus.server.FilterTestRedirector</filter-class>


<filter-mapping>
<filter-name>FilterRedirector</filter-name>
<url-pattern>/FilterRedirector</url-pattern>
</filter-mapping>



<servlet-name>JspRedirector</servlet-name>
<jsp-file>/jspRedirector.jsp</jsp-file>



THIS IS THE EXCEPTION:------------------------------------------

ERROR [org.apache.commons.digester.Digester] Parse Error at line 924 column 11: The content of element type "web-app" must match "(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*)".

Oh, one more thing. I'm using the servlet 2.3 DTD Spec
in the web.xml as such:
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">


JBoss3.2.2
Mandrake 9.1
JDK1.4.2_02

Any help would be greatly appreciated.
Thanks in advance.

[draftdog]

declare filters before servlets

as is explained in the error message (it's a part of the DTD, check the regular expression for more details concerning what goes where exactly)

here's the full DTD
