copied!<p>I think what you may be looking for is the use of the <a href="http://publib.boulder.ibm.com/infocenter/wasinfo/v7r0/index.jsp?topic=/com.ibm.websphere.nd.doc/info/ae/ae/txml_adminclient.html" rel="nofollow">WebSphere Thin Administrative Client</a>, which exposes Java APIs and provides access to the WAS <a href="http://publib.boulder.ibm.com/infocenter/wasinfo/v7r0/index.jsp?topic=/com.ibm.websphere.javadoc.doc/web/mbeanDocs/index.html" rel="nofollow">MBeans</a> that allow you to query the status of your servers/applications (along with many other management and monitoring tasks).</p> <p>First, you'll want to obtain a connection to WAS (the <a href="http://publib.boulder.ibm.com/infocenter/wasinfo/v7r0/index.jsp?topic=%2Fcom.ibm.websphere.javadoc.doc%2Fweb%2Fapidocs%2Fcom%2Fibm%2Fwebsphere%2Fmanagement%2FAdminClient.html" rel="nofollow"><code>AdminClient</code></a>) as follows:</p> <pre><code>Properties clientProps = new Properties(); clientProps.setProperty(AdminClient.CONNECTOR_TYPE, AdminClient.CONNECTOR_TYPE_SOAP); clientProps.setProperty(AdminClient.CONNECTOR_HOST, dmgrHostname); clientProps.setProperty(AdminClient.CONNECTOR_PORT, dmgrSoapConnectorPort); if (dmgrIsSecure) { clientProps.setProperty(AdminClient.CONNECTOR_SECURITY_ENABLED, "true"); clientProps.setProperty(AdminClient.USERNAME, wasUsername); clientProps.setProperty(AdminClient.PASSWORD, wasUserPassword); } AdminClient adminClient = AdminClientFactory.createAdminClient(clientProps); </code></pre> <p>Next, you'll want to query for the relevant MBeans, and then perform the relevant operations. In your case, you may be interested in the <a href="http://publib.boulder.ibm.com/infocenter/wasinfo/v7r0/index.jsp?topic=%2Fcom.ibm.websphere.javadoc.doc%2Fweb%2FmbeanDocs%2FClusterMgr.html" rel="nofollow">ClusterMgr</a> and/or <a href="http://publib.boulder.ibm.com/infocenter/wasinfo/v7r0/index.jsp?topic=%2Fcom.ibm.websphere.javadoc.doc%2Fweb%2FmbeanDocs%2FJ2EEApplication.html" rel="nofollow">J2EEApplication</a> MBeans. Here is an example that queries for the Cluster's state:</p> <pre><code>AdminClient adminClient = getAdminClient(target); ObjectName clusterMgr = (ObjectName)adminClient.queryNames( ObjectName.getInstance("WebSphere:*,type=ClusterMgr"), null).iterator().next(); String state = adminClient.invoke(clusterMgr, "getClusterState", new Object[] {clusterName}, new String[] {String.class.getName()}); </code></pre> <p>You can invoke further operations as desired, such as querying the individual cluster member's status.</p> <p>Also, in addition to querying, you can also <a href="http://publib.boulder.ibm.com/infocenter/wasinfo/v7r0/topic/com.ibm.websphere.javadoc.doc/web/apidocs/com/ibm/websphere/management/AdminClient.html#addNotificationListener(javax.management.ObjectName,%20javax.management.NotificationListener,%20javax.management.NotificationFilter,%20java.lang.Object)" rel="nofollow">register notifications</a> so that your program can be notified when certain events happen, such as a change in state of clusters, servers, or applications.</p>

Querying!
