The java side needs to understand that 0.0.0.0 is useless as a client address and send something useful. Trick is deciding what's useful. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (MODCLUSTER-110) Split ModClusterServiceMBean.ping(String) into 3 methods

by Paul Ferraro (JIRA)

Split ModClusterServiceMBean.ping(String) into 3 methods -------------------------------------------------------- Key: MODCLUSTER-110 URL: https://jira.jboss.org/jira/browse/MODCLUSTER-110 Project: mod_cluster Issue Type: Feature Request Reporter: Paul Ferraro Assignee: Jean-Frederic Clere Fix For: 1.1.0.CR1 Currently the ModClusterServiceMBean.ping(String) method does 3 things: 1. If parameter is null, send a PING command that determines the accessibility/health of each proxy. 2. If parameter is not a url, interpret the parameter as a jvm route and send a PING command that determines the accessibility of the node, configured with the specified jvm route, from each proxy. 3. If parameter is as a url, interpret the parameter as a url and send a PING command that determines the accessibility of the node (which may or may not be configured in the proxy already) containing a connector matching the protocol, host, and port of the url, from each proxy . Rather than 1 multi-purpose function - this method should be split in to 3, corresponding to the 3 functions identified above: Map<InetSocketAddress, String> ping(); Map<InetSocketAddress, String> ping(String jvmRoute); Map<InetSocketAddress, String> ping(String protocol, String host, int port); or perhaps: Map<InetSocketAddress, String> pingProxies(); Map<InetSocketAddress, String> pingNode(String jvmRoute); Map<InetSocketAddress, String> pingConector(String url); -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
