It is telling you either you have elements out of order, or elements that do not belong.
Try to do:
<filter>
  <filter-name>theFilter</filter-name>
  <filter-class>org.gui.myFilter</filter-class>
</filter>
<filter>
  <filter-name>theFilter</filter-name>
  <filter-class>org.gui.myFilter</filter-class>
</filter>
<filter-mapping>
  <filter-name>theFilter</filter-name>
  <url-pattern>/fetch.jsp</url-pattern>
</filter-mapping>
<filter-mapping>
  <filter-name>theFilter</filter-name>
  <url-pattern>/query.jsp</url-pattern>
</filter-mapping>Then double check spelling and such.
