Solution:
wrong Jboss-web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<jboss-web>
    <security-domain flushOnSessionInvalidation="false"/>
    <module>
        <web>
            <web-uri>FdrHlgContractComparisionEar-WebModule.war</web-uri>
            <context-root>/FdrHlgContractComparisionEar-WebModule</context-root>
        </web>
    </module>
    <context-root>/FdrHlgContractComparisionEar-WebModule</context-root>
</jboss-web>
Correct Jboss-web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<jboss-web>
    <security-domain flushOnSessionInvalidation="false"/>
    <context-root>/conmasEar-WebModule</context-root>
</jboss-web>
