Need help running visualvm on Windows when under VMWare
I am doing some Java development on Windows 7 x64 running inside VMWare Fusion 3.x (OSX). I have installed JDK6 (update 26), set JAVA_HOME to the path (no trailing slash), and restarted my command prompt.
I can successfully launch the program. During startup it runs the calibration and then fails with this error:
"Could not create directory\VMWare-host\Shared Folders\ .nbprofiler" (no space after that slash but the markup was hiding the period)
I can click to continue, but when I'm in the program I cannot do CPU or Memory profiling. I throws up a similar error box:
"Error retrieving saved calibration data for target JVM: Could not create...(same as earlier)"
Once upon a time I had this working by passing the --userdir flag and -J-Dnbprofiler.home during startup, but that trick isn't working anymore.
(The c开发者_JS百科omplete command was: jvisualvm --userdir c:\Users\myname -J-Dnbprofiler.home=c:\Users\myname )
How can I force jvisualvm to save its calibration data on a "real" drive instead of the vmware network drive and get this working?
.nbprofiler directory is derived from user.home system property. I am not sure what you did to Windows installation, but your user.home points to directory\VMWare-host\Shared Folders
. So one solution is to fix the Windows installation, so that Java recognize c:\Users\myname
as your user home directory. If that fails for some reason you can use nbprofiler.home
property to override it, as you correctly wrote. However you should point it to the nonexistent directory, so you should start VisualVM with the following commandline:
jvisualvm -J-Dnbprofiler.home=c:\Users\myname\nbprofiler --userdir c:\Users\myname\visualvm_userdir
One last note, even if the profiler part is not working, you should be able to use sampling in the 'Sampler' tab.
Try disable Sharing for the VM.
It works for me with Windows 7 x86 in Fusion with Sharing disabled (and Sharing is the mechanism providing the folder you cannot write to).
I found the following command works for me.
visualvm -J-Duser.home=%HOME%
Also, I needed to add -Duser.home=%HOME% to my app startup command.
I had defined nbprofile.home and userdir, but I was still getting an error when the Profiler was running against my app: Profiler Agent Error: Could not create directory\vmware-host\Shared Folders.nbprofiler.
I discovered that the Profiler was using user.home defined by my app rather than the one with visualvm. Both seem to be needed.
