hi all
i am just modifing web.xml file by adding this information

<context-param>
<param-name>breed</param-name>
<param-value>breed</param-value>
</context-param>

<listener>
<listener-class>classes.com.MyServletContextListener</listener-class>
</listener>

when i try to validate the web.xml file then it give following error

Parse Error at line 40 column 11: The content of element type "web-app" must match "(icon?,display-name?,description?,distributable?,context-param*,filter*,filter-mapping*,

listener*,servlet*,servlet-mapping*,session-config?,mime-mapping*,welcome-file-list?,error-page*,

taglib*,resource-env-ref*,resource-ref*,security-constraint*,login-config?,security-role*,env-entry*,ejb-ref*,ejb-local-ref*)".

Every thing is right why it is giving error like this? When i remove these lines then there is no error occurs.

what is going on tell me?

whole web.xml file. i commented out above information.

You are using version 2.3 of the specification, where the order of elements is important. I think you should move the context-param and listener tags before the servlets.
