Re: Parse Error in the tag library descriptor: Element "web-app" does not allow "servlet" here

[T. Park]

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...   -Thom   Adrian Perju wrote: Hello, I am using jakarta tomcat 3.1 and stuts.
