I am unable to configure ManagerBalancerName in httpd. Getting below error. I tried by loading all modules by commenting. But no luck.

AH00526: Syntax error on line 556 of C:/httpd-2.4.9-x86/Apache24/conf/httpd.conf:

Invalid command 'ManagerBalancerName', perhaps misspelled or defined by a module not included in the server configuration

<VirtualHost 192.168.1.140:10003>

    Deny from all

  # This directive allows you to view mod_cluster status at URL http://192.168.1.140:10003/mod_cluster-manager

And I have few questions

1) What is the need of httpd when making Cluster configuration?

2) Is it possible cluster configuration with JBoss web server?

3) What are the alternative ways to configure cluster?
