Issue

• We refer Can JBoss be configured to share sessions across multiple web applications? and Red Hat JBoss EAP 7.0 Development Guide - 3.7.4. Configuring Session Sharing between Subdeployments in Enterprise Archives to configure session sharing WAR module subdeployments contained in an EAR.
  • The development guide provides the example META-INF/jboss-all.xml
  • Example: META-INF/jboss-all.xml

<jboss umlns="urn:jboss:1.0">
    <shared-session-config xmlns="urn:jboss:shared-session-config:1.0">
        <max-active-sessions>10</max-active-sessions>
        <session-config>
            <session-timeout>0</session-timeout>
            <cookie-config>
                <name>JSESSIONID</name>
                <domain>domainName</domain>
                <path>/cookiePath</path>
                <comment>cookie comment</comment>
                <http-only>true</http-only>
                <secure>true</secure>
                <max-age>-1</max-age>
            </cookie-config>
        </session-config>
        <tracking-mode>COOKIE</tracking-mode>
    </shared-session-config>
    <replication-config>
        <cache-name>web</cache-name>
        <replication-granularity>SESSION</replication-granularity>
    </replication-config>
</jboss>

• However, we failed to deploy by the "Example: META-INF/jboss-all.xml" with XML parsing error as 'urn:jboss:shared-session-config:1.0 tracking-mode'.
  • There is an error for <tracking-mode> element as below and also if it removed, there is an error for <replication-config> element:
