Tomcat 5.5.23: Cannot Deploy hello-world.war
Hi all,
I have a HelloWorld servlet. Real simple. Packaged as hello-world.war.
I copy it to $CATALINA_HOME/webapps. My environment:
Operating System: Fedora Core 5 Linux 2.6.15-1.2054
Java Version: 1.6.0-b105
JAVA_HOME = /opt/SDK/jdk
CATALINA_HOME = /apache-tomcat-5.5.23
CLASSPATH
= .:/apache-tomcat-5.5.23/common/lib/servlet-api.jar:/apache-tomcat-5.5.23/common/lib/jsp-api.jar
When I run $CATALINA_HOME/bin/startup.sh, the following appears in
catalina.out. Note the SEVERE message...

Any clues? Here's the application's web.xml and context.xml files:
$ cat $CATALINA_HOME/webapps/hello-world/WEB-INF/web.xml
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"

xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee

</servlet>
<servlet-mapping>
<servlet-name>HelloWorld</servlet-name>
<url-pattern>/HelloWorld</url-pattern>
</servlet-mapping>
</web-app>
$ cat $CATALINA_HOME/conf/Catalina/localhost/hello-world.xml
<Context path="/hello-world" docbase="hello-world.war" reloadable="true"
debug="0">
<Loader checkInterval="1"/>
</Context>
All the servlet examples at http://localhost:8080/servlets-examples/
work fine. But if I request http://localhost:8080/hello-world/HelloWorld
I get HTTP 500 with the following stack trace:

I really don't know what's wrong. Any help is gladly appreciated.
