exception filter not found as a child of web-app in unordered_sequence:

[iltrex]

We installed a new server, with the jboss AS version 6.

The web.xml that has always worked fails, now.

We get an error that says something about unordered_sequence.

I cannot find much on google, can you help ?

The exception is

11:04:38,255 ERROR [AbstractKernelController] Error installing to Parse: name=vfs:///usr/java/jboss-6.0.0.Final/server/default/deploy/HelpDocumentation.war state=PreParse mode=Manual requiredState=Parse: org

the web.xml file is very simple

<?xml version="1.0" encoding="UTF-8"?>

<web-app >

      <filter>

                    <filter-name>ExpiresFilter</filter-name>

                    <filter-class>com.cj.expire.ExpiresFilter</filter-class>

                    <init-param>

                              <param-name>expires</param-name>

                              <!-- in seconds -->

                              <param-value>60</param-value>

                    </init-param>

          </filter>

          <filter-mapping>

                    <filter-name>ExpiresFilter</filter-name>

                    <url-pattern>*.html</url-pattern>

          </filter-mapping>

</web-app>

Try adding an xsd declaration in that web.xml as follows:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
         xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

<filter>
                    <filter-name>ExpiresFilter</filter-name>
                    <filter-class>com.cj.expire.ExpiresFilter</filter-class>
                    <init-param>
                              <param-name>expires</param-name>
                              <!-- in seconds -->
                              <param-value>60</param-value>
                    </init-param>
          </filter>
          <filter-mapping>
                    <filter-name>ExpiresFilter</filter-name>
                    <url-pattern>*.html</url-pattern>
          </filter-mapping>

</web-app>

good, this worked perfectly for the example web.xml file.

Now, I tried it on other applications, and I get a new error. Here exception and web.xml file...

thanks for help.

Deployment "vfs:///usr/java/jboss-6.0.0.Final/server/default/deploy/sa.war" is in error due to the following reason(s): org.xml.sax.SAXException: cvc-complex-type.2.4.a: Invalid content was found starting with element 'servlet-class'. One of '{"http://java.sun.com/xml/ns/javaee":description, "http://java.sun.com/xml/ns/javaee":display-name, "http://java.sun.com/xml/ns/javaee":icon, "http://java.sun.com/xml/ns/javaee":servlet-name}' is expected. @ vfs:///usr/java/jboss-6.0.0.Final/server/default/deploy/sa.war/WEB-INF/web.xml[6,18]

the file is

it seems that, if I invert servlet-class and servlet-name order, it works.

but I have tens of servlets and tens of web.xml files, I would like to avoid changing all of them.

Is there any xsd declaration that will make them work in any order ?
