A complete stack track trace might help; "NullPointerException" by
itself doesn't say much....

Hi all again
I am trying to create a custom component for my menu, header and
footer. I
created a Menu.html whose content is a simple html table.
I created a .jwc file in my WEB-INF directory with the following
content:
<component-specification class="org.apache.tapestry.BaseComponent"
allow-body="no" allow-informal-parameters="no">
</component>
But when I deploy my application, Tomcat starts dumping this error
in an
endless loop:

org.apache.catalina.core.ContainerBase
$ContainerBackgroundProcessorprocessChildren
SEVERE: Exception invoking periodic operation:
java.lang.NullPointerException
...
I am following these pages on creating custom components, but I
cant find
out what is it I'm doing wrong:
