How to use loadAgent method of com.sun.tools.attach.VirtualMachine class

Best Powermock code snippet using com.sun.tools.attach.VirtualMachine.loadAgent

Source:VirtualMachine.java

...44 * Alternatively, a <code>VirtualMachine</code> instance is obtained by invoking the45 * {@link #attach(VirtualMachineDescriptor) attach} method with a {@link46 * com.sun.tools.attach.VirtualMachineDescriptor VirtualMachineDescriptor} obtained47 * from the list of virtual machine descriptors returned by the {@link #list list} method.48 * Once a reference to a virtual machine is obtained, the {@link #loadAgent loadAgent},49 * {@link #loadAgentLibrary loadAgentLibrary}, and {@link #loadAgentPath loadAgentPath}50 * methods are used to load agents into target virtual machine. The {@link51 * #loadAgent loadAgent} method is used to load agents that are written in the Java52 * Language and deployed in a {@link java.util.jar.JarFile JAR file}. (See53 * {@link java.lang.instrument} for a detailed description on how these agents54 * are loaded and started). The {@link #loadAgentLibrary loadAgentLibrary} and55 * {@link #loadAgentPath loadAgentPath} methods are used to load agents that56 * are deployed in a dynamic library and make use of the <a57 * href="../../../../../../../../technotes/guides/jvmti/index.html">JVM Tools58 * Interface</a>. </p>59 * <p/>60 * <p> In addition to loading agents a VirtualMachine provides read access to the61 * {@link java.lang.System#getProperties() system properties} in the target VM.62 * This can be useful in some environments where properties such as63 * <code>java.home</code>, <code>os.name</code>, or <code>os.arch</code> are64 * used to construct the path to agent that will be loaded into the target VM.65 * <p/>66 * <p> The following example demonstrates how VirtualMachine may be used:</p>67 * <p/>68 * <pre>69 * <p/>70 *      // attach to target VM71 *      VirtualMachine vm = VirtualMachine.attach("2177");72 * <p/>73 *      // get system properties in target VM74 *      Properties props = vm.getSystemProperties();75 * <p/>76 *      // construct path to management agent77 *      String home = props.getProperty("java.home");78 *      String agent = home + File.separator + "lib" + File.separator79 *          + "management-agent.jar";80 * <p/>81 *      // load agent into target VM82 *      vm.loadAgent(agent, "com.sun.management.jmxremote.port=5000");83 * <p/>84 *      // detach85 *      vm.detach();86 * <p/>87 * </pre>88 * <p/>89 * <p> In this example we attach to a Java virtual machine that is identified by90 * the process identifier <code>2177</code>. The system properties from the target91 * VM are then used to construct the path to a <i>management agent</i> which is then92 * loaded into the target VM.
