Use -javaagent without packaging agent into a jar

Question

Is it possible to run java -javaagent:myagent.jar some.package.Main without having agent packaged to a jar? Something like java agent.MyAgent some.package.Main

I have a source code for an agent and would like to be able to debug it and later change it so it is not needed to use -javaagent at all but instead select some.package.Main to execute through GUI.

BTrace is able to connect to a running process using PID or connect to a process using -javaagent . I'm looking for something similar to first approach (using PID), but so I can start a process from scratch as well.

在Java 6中，您可以使用Attach API以编程方式加载代理程序（不使用-javaagent ），但仍需要将代理程序打包为jar。
