Hi, on as side note:
1) Where can I find more information regarding the parameters that can be used in the <contextManager class="org.apache.axis2.clustering.context.DefaultContextManager"> element ? Can I define a backup node for one Tomcat (so not all Tomcats in the group get all messages) ? 2) What is the relationship with : http://wso2.org/library/articles/wso2-carbon-cluster-configuration-language Can I also use this one ? Seems that there are a lot more options to define ? Thx in advance. H.
