Yup, sure. All you need to do is change the web descriptor for the servlets. You can find a "web.xml" file in your project directory, under "WEB-INF".
Change the following code:
<servlet-mapping>
<servlet-name>Webservices</servlet-name>
<url-pattern>/ws/*</url-pattern>
</servlet-mapping>
to:
<servlet-mapping>
<servlet-name>Webservices</servlet-name>
<url-pattern>/ws</url-pattern>
</servlet-mapping>
