Summary: Unable to start ReplicatedContext
Product: Tomcat 6
Version: 6.0.0
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: Aray_CN@163.com
I try to test the Cluster function. I got a problem: something like following
apears in the $CATALINA_HOME/logs/catalina.out
SEVERE: Unable to start ReplicatedContext
java.lang.ClassCastException: org.apache.naming.resources.ProxyDirContext
cannot be cast to java.io.Serializable
at
org.apache.catalina.tribes.tipis.AbstractReplicatedMap$MapEntry.setValue
(AbstractReplicatedMap.java:1060)
I didn't change any file in $CATALINA_HOME except server.xml, the any thing I
changed in server.xml is uncomment the line:
<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>.
and I add a context configuration file test.xml to
$CATALINA_HOME/conf/Catalina/localhost with the flolling content
[Aray@BONC-01 conf]$ cat Catalina/localhost/test.xml
<Context
className="org.apache.catalina.ha.context.ReplicatedContext"
path="/test" docBase="/var/www/ClusterTest"
debug="0" privileged="true" reloadable="true"
>
the web.xml file in /var/www/ClusterTest has no <distributable/> element
I am worrying about I can't explain the problem clearly with my poor English.
So I paste the stepes I do as following:
[Aray@BONC-01 apache-tomcat-6.0.2]$ which java
/usr/java/jdk1.6.0/bin/java
