          Do you have a Host defined in the server.xml?

          • 2. Re: error mod_cluster

            my server.xml

             

                    <Host name="localhost"
                       autoDeploy="false" deployOnStartup="false" deployXML="false"
                       configClass="org.jboss.web.tomcat.security.config.JBossContextConfig"
                       >

                        <Valve className="org.jboss.web.tomcat.service.jca.CachedConnectionValve"
                            cachedConnectionManagerObjectName="jboss.jca:service=CachedConnectionManager"
                            transactionManagerObjectName="jboss:service=TransactionManager" />

                     </Host>
                     <Host name="zzzzz" autoDeploy="false" deployOnStartup="false" deployXML="false">
                            <Alias>xxxxx.xxxx.xx</Alias>
                            <Alias>yyyyy.xxxx.xx</Alias>
                           

                                <DefaultContext cookies="true" crossContext="true" override="true"/>
                     <Valve className="org.jboss.web.tomcat.service.jca.CachedConnectionValve"
                            cachedConnectionManagerObjectName="jboss.jca:service=CachedConnectionManager"
                            transactionManagerObjectName="jboss:service=TransactionManager" />

              that looks to be something wrong on the httpd side.

              In httpd.conf put LogLevel debug and look to the ENABLE-APP message on should cause the error. Copy + Paste it in forum.

                  It seems that is a bug in both 1.0.2 and 1.1.0 Beta1 I have created a JIRA.
