JBoss wildfly 10 NoClassDefFoundError at migrate from JBoss 4.2

Question

I have a spring mvc application running into JBoss 4.2. I'm trying migrate this web app to JBoss wildfly 10 (wildfly-10.0.0.Final version).

When I try deploy my app show this error:

"{\"WFLYCTL0080: Failed services\" => {\"jboss.deployment.unit.\\\"myApp.war\\\".POST_MODULE\" => \"org.jboss.msc.service.StartException in service jboss.deployment.unit.\\\"myApp.war\\\".POST_MODULE: WFLYSRV0153: Failed to process phase POST_MODULE of deployment \\\"myApp.war\\\"
Caused by: java.lang.RuntimeException: WFLYSRV0177: Error getting reflective information for class org.ajaxtags.tags.AjaxDisplayTag with ClassLoader ModuleClassLoader for Module \\\"deployment.myApp.war:main\\\" from Service Module Loader
Caused by: java.lang.NoClassDefFoundError: au/id/jericho/lib/html/Segment
Caused by: java.lang.ClassNotFoundException: au.id.jericho.lib.html.Segment from [Module \\\"deployment.myApp.war:main\\\" from Service Module Loader]\"}}"

Looking for the web, I read that I need to load the jar "jericho-html-2.6.1.jar". To do it, I added in ${wildfly_home}/modules/system/layers/base/au/id/jericho/lib/html/main the jericho-html-2.6.1.jar and this module.xml

<?xml version="1.0" encoding="UTF-8"?>
    <module xmlns="urn:jboss:module:1.1" name="au.id.jericho.lib.html">
    <resources>
        <resource-root path="jericho-html-2.6.1.jar"/>
    </resources>
    <dependencies>
    </dependencies>
</module>

I added the extension in standalone.xml

<extension module="au.id.jericho.lib.html"/>

But I get same error.

Why do you add the extension in standalone.xml ?? You should add a WEB-INF/jboss-deployment-structure.xml file to your war with :

<jboss-deployment-structure>
    <deployment>
        <dependencies>
            <module name="au.id.jericho.lib.html" />
        </dependencies>
    </deployment>
</jboss-deployment-structure>
