Thanks for your response , but I forgot to write
how I've mapped my Servlet (it is one servlet that are
hunging under
$CATALINA_HOME/webapps/myAplication/WEB-INF/classes/mypackage/
and its name is GNServletContext) in my web.xml:
<servlet>
<servlet-name>GNServletContext</servlet-name>
<servlet-class>org.apache.catalina.servlets.GNServletContext</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>0</param-value>
</init-param>
<init-param>
<param-name>listings</param-name>
<param-value>true</param-value>
</init-param>
<!-- Uncomment this to enable read and write
access -->
<!--
<init-param>
<param-name>readonly</param-name>
<param-value>false</param-value>
</init-param>
-->
<!--load-on-startup>1</load-on-startup-->
</servlet>
<!-- The mapping for the webdav servlet -->
<servlet-mapping>
<servlet-name>GNServletContext</servlet-name>
<url-pattern>/mypackage/</url-pattern>
</servlet-mapping>
Are the servlet correctly mapped?.
Could the error be in servlet-class tags?
I don't know what put between these tags.
I have probed with put:
<servlet-class>//localhost:8080/myAplication/WEB-INF/classes/mypackage/GNServletContext</servlet-class>
But the same error appear in the browser.
Can you say me what I have to put between this tags?.
A lot of Thanks!
