' Update Note 2: The Attach API is in tools.jar, so you will need to add /lib/tools.jar in your CLASSPATH to compile and run the example on JDK 6.'. A tool, written in the Java Language, uses this API to attach to a target virtual machine (VM) and load its tool agent into the target VM. According to this page, the VirtualMachine class that you linked to is part of the tools.jar file which is only distributed in a JDK (not a JRE). The following example demonstrates how VirtualMachine may be used: // attach to target VM VirtualMachine vm VirtualMachine. java) Click menu 'File Open File.

先前显示的屏幕快照显示了 amx-support:type=boot-amx MBean上可用的 bootAMX操作。需要运行此程序以使其他GlassFish提供的AMX MBean可用。 Groovy代码的下一个片段，我称为 bootAmx(MBeanServerConnection) ，调用此 bootAMX操作来指示GlassFish通过其JMX接口显露更多细节。 bootAmx（MBeanServerConnection） /*** 'Boot AMX' on GlassFish.** mbeanServer MBeanServerConnection to be used to invoke bootAMX* operation. package Provides the API to attach to a Java virtual machine. : . vm VirtualMachine.attach(pid) vm.loadAgent(attachJarPath, properties) I got this error: java.io.IOException: Premature EOF at .

如上图所示，GlassFish在本地使用PID（AKA进程ID或pid）1584运行。首先，我将使用Groovy通过Attach API访问相关的MBeanServerConnection 。如下面的Groovy代码（接下来的两个代码清单）所示，此操作已完成，在该代码中， retrieveServerConnection(String)方法接受PID并返回该Java进程的 MBeanServerConnection 。该方法使用代码清单中的另一种方法 retrieveUrlForPid(String, String) ，该方法使用Attach API为Java进程提供JMXServiceURL 。 resolveServerConnection（String） /*** Provide an MBeanServerConnection based on the provided process ID (pid).** pid Process ID of Java process for which MBeanServerConnection is* desired.* MBeanServerConnection connecting to Java process identified by pid.*/ĭef MBeanServerConnection retrieveServerConnection(String pid) VirtualMachine.
