如何为Java应用程序提供唯一的进程名称？

Question

I've noticed that when I start Netbeans it shows up in the task manager as netbeans.exe as all my own Java applications show up as java.exe or javaw.exe .

How can I change that so my process names shows up as myapp.exe ?

Answer 1

The process name is the name of the JVM. So if you rename the jvm you have an other process name. There are some tools which can do that for you. For example Launch4J

Answer 2

IMO the best option is to choose one of the many open source launchers. They all provide a nicer deployment container than java.exe and a batch file.

I've compiled a list of them after a brief search on google (in no particular order and may not be exhaustive):

• NSIS
• Janel (dead link)
• JSmooth
• Launch4J
• WinRun4J

(full disclosure: i work on winrun4j)

Answer 3

Not easily. The easiest way (but not nice!) would be to simply copy the java.exe (only 68k on my system, so perhaps practical!)

If you're worried about identifying which java process is which (eg is one consuming memory/CPU etc.), use the standard tool jps to identify the Java processes

Answer 4

Netbeans and Eclipse both ship with an .exe file that in turns launches a JVM. The exe itaself probably does nothing after launching the VM. You see the NetBeans javaw.exe in the Task Manager also, I suspect.

So you'll need to write a native exe (using some windows tool) that does a similar thing.

Answer 5

Just answered this a second ago here: Get JVM to grow memory demand as needed up to size of VM limit?

It's actually a lot easier than folks are saying (but you do have to have ac/c++ compiler handy).

Answer 6

There are mainly 2 approaches: one is as already described: using tools like Launch4j, WinRun4J to create native Windows launchers.

Another approach that seems better is to use Apache Procrun to wrap the java application as a Windows service. During the install service process, we can give the process an meaningful name such as OurApp.exe.

All we need do is rename prunsrv.exe to OurApp.exe and replace every occurrence of prunsrv.exe in our install|start|stop|uninstall service scripts to MyApp.exe.
