Re: Parse Error in the tag library descriptor: Element "web-app" does
not allow "servlet" here
Hi,
based on the web.xml dtd, the servlet-mappings cannot be followed by
servlets, order is important -
servlet mappings must follow servlets. (though tomcat 3.2 relaxed
this rule)
Servlet 2.2 web application DTD extract:
<!ELEMENT web-app (icon?, display-name?,description?, distributable?,
context-param*,servlet*,
servlet-mapping*,... >
you should do something like the following:
<web-app>
<!-- servlets... -->
<servlet> servlet 1... </servlet>
<servet> servlet 2.. </servlet>
<!-- servlet mappings -->
<servlet-mapping> mapping 1 </servlet-mapping>
<servlet-mapping> mapping 2 </servlet-mapping>
</web-app>
Tomcat 3.2 didn't enforce this mapping rule, tomcat 4 does - can't
explain why Tomcat 3.1 is catching this though...
