Eclipse web.xml'de elementlerin sıralarında hata olduğu zaman aşağıdaki gibi hata verebilmektedir:
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*)".
Örneğin aşağıdaki gibi bir web.xml hata vermektedir.
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app>
<welcome-file-list>
<welcome-file>index.xhtml</welcome-file>
</welcome-file-list>
<display-name>VasClient Test Web Projesi</display-name>
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
</web-app>
Bu web.xml'de welcome-file-list elementini en alta alırsak bu hatanın kalktığını görebilirsiniz :
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app>
<display-name>VasClient Test Web Projesi</display-name>
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.xhtml</welcome-file>
</welcome-file-list>
</web-app>
Bu dökümanda sıranın "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*" da belirtilen sıraya uymalıdır
