web-app element doesn't accept id attribute, try to remove it.

[Muhammad Imad Qureshi]

Well this application is actually running with id attribute inside web-app. The only thing we are adding with this deployment is following servlet (only following lines are new in web.xml)

  <servlet>
                <servlet-name>XMLViewRenderService</servlet-name>
                <servlet-class>
                        com.tuc.g2.apps.webapps.arch.servlet.XMLViewRenderService
                </servlet-class>
                <init-param>
                        <param-name>caching</param-name>
                        <param-value>true</param-value>
                </init-param>
                <load-on-startup>1</load-on-startup>
        </servlet>
        <servlet-mapping>
                <servlet-name>XMLViewRenderService</servlet-name>
                <url-pattern>/XMLViewRenderService</url-pattern>
        </servlet-mapping>
  

[Hussein Baghdadi]

Try to move the new servlet definition and place it with other servlets definitions, servlets-mapping should follow.

[Mark E Hansen]

The error you're getting is telling you the order the elements must appear in the web-app element. The elements must appear in the correct order.

[Muhammad Imad Qureshi]

So that means I shoould follow what John said. Is that right? Because each servlet has a load-on-startup =1. Or should I change the load on startup value to 2 for this new servlet?

Thanks
Imad

[Hussein Baghdadi]

Just group servlets definitions together.
To be more specific, follow web-app_2_3.dtd rules.

[Mark E Hansen]

The <load-on-startup> element has nothing to do with this issue. The problem is in the ordering of the elements within the <web-app> element.

[Muhammad Imad Qureshi]

thanks guys. It worked.
