java - 访问 Websphere 变量

Question

我想从 java 类中获取 Websphere 变量 ORB_LISTENER_PORT 的值。怎么做？

我已经阅读了topik并理解了它。我认为我必须使用一些值而不是“expandVariable”。但是什么样的价值呢？

我自己解决了这个问题。以下代码示例和他的工作结果。

import com.ibm.websphere.management.Session;
import com.ibm.websphere.management.configservice.ConfigService;
import com.ibm.websphere.management.configservice.ConfigServiceFactory;
import com.ibm.websphere.management.configservice.ConfigServiceHelper;

    public void readWebsphereConfiguration( PrintWriter out ){
        try{
            out.println("<p>Using ConfigService to get the hostName and port of this server.</p>");
            Session session = new Session();
            ConfigService cs = ConfigServiceFactory.getConfigService();

            ObjectName[] serverIndexONs = cs.resolve(session, "ServerIndex=");
            String hostName = (String) cs.getAttribute(session, serverIndexONs[0], "hostName");
            out.println("<p>HostName: " + hostName + "</p>");

            ObjectName[] namedEndPointsONs = cs.queryConfigObjects(session, serverIndexONs[0], ConfigServiceHelper.createObjectName(null, "NamedEndPoint"), null);
            for (int i = 0; i < namedEndPointsONs.length; ++i){
                String str = (String) cs.getAttribute(session, namedEndPointsONs[i], "endPointName");
                ObjectName[] theEndPoints = cs.queryConfigObjects(session, namedEndPointsONs[i], ConfigServiceHelper.createObjectName(null, "EndPoint"), null);
                String szValue = "";
                if(theEndPoints != null && theEndPoints.length > 0){
                    szValue = ((Integer) cs.getAttribute(session, theEndPoints[0], "port")).toString();
                }
                out.println("<p>" + str + "=" + szValue +"</p>");
            }
        }catch(Exception e){
            out.println("<p>Exception while trying to fetch the hostname and port information.: " + e.getMessage() + "</p>");
            out.println("<p>Exception:" + e.getStackTrace() + "</p>");
        }
    }
