Tomcat startup error

P: n/a
Hello,

I'm getting the following error when trying to start Apache Tomcat.The
version shows up in the snapshot. I can't figure out why this is
happening. It is aparently the <context-param> tag. If I remove it
tomcat starts properly. I have pasted web.xml below with the error.

WEB.XML
?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>
<servlet>
<servlet-name>rooms</servlet-name>
<servlet-class>ListRooms</servlet-class>
</servlet>

<context-param>
<param-name>listroom_path</param-name>
<param-value>context_chat</param-value>
</context-param>
</web-app>

ERROR:
Starting service Tomcat-Standalone
Apache Tomcat/4.0.5
PARSE error at line 17 column 11
org.xml.sax.SAXParseException: 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*,welco
me-file-list?,error-page*,taglib*,resource-env-ref*,resource-ref*,security-const
raint*,login-config?,security-role*,env-entry*,ejb-ref*,ejb-local-ref*)".
Starting service Tomcat-Apache
Apache Tomcat/4.0.5

Also posting a previous question which went unanswered:

In the case of servlets, if the SingleThreadModel interface is "NOT"
implemented, can we assume that the container will create only one
Instance of the servlet ?? Or is this container dependent.

Thanks in advance,

Devu.

Hi,

The <context-param> tag must be placed at the start of the <web-app> tag.
In other words, it can follow either the <web-app> tag or its
<description></description> tag only. This means that you should modify
your web.xml and make sure that <context-param> tag proceeds the <servlet>
tag. This should do it.

That did it. Thank you so much. My second question is still unanswered though.
