No matter what I start up, Visual VM just gives me "Unknown Application" and "Not supported for this JVM" on my Mac.
I've tried JBoss, Jetty, Eclipse - just to see if it would be able to identify / profile anything, and so far, nada.
$ java -version
java version "1.6.0_17"
Java(TM) SE Runtime Environment (build 1.6.0_17-b04-248-10M3025)
Java HotSpot(TM) 64-Bit Server VM (build 14.3-b01-101, mixed mode)
Running on Snow Leopard. I've tried with the default visual vm (which appears to be 1.0) and a freshly downloaded version from https://visualvm.dev.java.net/download.html .
I also can't seem to get jconsole to connect to anything, and I think the two are related. I am using "-Xshare:off" as recommended to prevent crashing, but I can't connect anyway, so that's moot.
I've also verified that Visual VM and these other apps are running from the same JVM:
VisualVM:

I have no idea what's wrong. Anyone have any ideas?
I don't know if I have an answer, but is there any chance that you have an underscore in your user name?
I see similar problems, and found that there is an old bug in jps that causes problems if you have an underscore in your username. This was fixed in Java 1.6 (by Sun), but I'm not sure it was by Apple. I've found that if I use a user that does not have an underscore in the user name, things work on my Mac. But, with the underscore... well, not so much.

Based on what I read here, in order to install CF version 2 on my handheld device, I should copy over one of the cab files here:
...but which one?
The device in question is a Symbol 3090, which currently has only CF version 1.0.3316.00 (1.0 SP2) installed. The OS version of the device is 05.00.1400
The device CPU is presumably 'ARMV4I' as a similar device (Motorola 3190) says that it is equipped with such.
UPDATE
Based on what I see here when I click "this link" here:
-- OR -- If you have Windows Mobile 5 or newer on your device, click this link and save the file to the desktop of your computer.
...it seems "NETCFv2.wm.armv4i.cab" is probably the best choice.
Any refutations?
UPDATE 2
I copied the file I reckoned to be the one, and clicked it on the device, but:
What in Sam L. Clemens' illustrious memory is going on here?!?
UPDATE 3
I then copied over the other file from the link above, which was slightly different (2.12MB as opposed to 2.14MB, for one thing), and tried to run it, and got the same err msg as above.
UPDATE 4
Trying to install from the last link, I see:
UPDATE 5
Actually, it turns out that what I might really need is to install CF version 1 after a cold boot of the device...but I don't know if version 1 of CF is still available. That's the only version the existing .exe will run on, but my PC only has cab files for versions 2 and 3.5...???
UPDATE 6
In the most recent version of the .exe (builds and compiles, but won't run on either device), it has three, count 'em three mscorlibs in its References area; the versions are:
1.0.5000.0
2.0.0.0
3.5.0.0
They all have the same public key token (the same as shown in the screen shot)
The only other multi-reference is System, which has both version 2 and 3.5
AND, below System.Xml, there are three coredll.dlls, albeit spelled differently:
coredll.dll
CoreDll.dll
CoreDll.DLL
(no info for any of them...???)
UPDATE 7
I copied NETCFv2.wce4.ARMV4.cab to the 3090.
I 2-clicked it on the device, but got this:
And so, I retreated (selected "No").
Thus continue unabated the travails of an accidental handheld developer.
UPDATE 8
The project is set to Framework Version == v2.0, Platform == Windows CE, Target Device == Windows Mobile 6 Classic Emulator (one of the few emulator choices I have), and the output shows that it is ARMV4i that is being deployed:
Deploying '%CSIDL_PROGRAM_FILES%\Microsoft SQL Server Compact Edition\v3.5\Devices\wce500\ARMV4i
\sqlce.ppc.wce5.armv4i.CAB'
Deploying '%CSIDL_PROGRAM_FILES%\Microsoft SQL Server Compact Edition\v3.5\Devices\wce500\ARMV4i
\sqlce.repl.ppc.wce5.armv4i.CAB'
Deploying '%CSIDL_PROGRAM_FILES%\Microsoft SQL Server Compact Edition\v3.5\Devices\wce500\ARMV4i

Deploying 'C:\Program Files (x86)\Motorola EMDK for .NET\v2.8\SDK\Smart Devices\wce500\armv4i\symbol.all.arm.cab'
And when I run the .exe in the emulator, it fails with, "Error - An unexpected error has occurred in Platypus.exe
Select Quit and restart this program, or select Details for more information.
This application requires a newer version of the MS .NET Compact Framework than the version installed on this device."
Selecting the "Details" button augments the mental anguish with, "TypeLoadException
This application requires a newer version of the MS .NET Compact Framework than the version installed on this device."
Assuming your are using the WinCE 4.2 version of the 3090 (it comes in 4.2 and 5.0), you should proceed with the install using NETCFv2.wce4.ARMV4.cab. "The program is not compatible..." message is a warning only, and not a very smart one. There is even a way to edit the cab to remove that warning if you wanted to, though my memory fails me on the exact way to do it. I've had to do it to allow a silent install before (otherwise the nag screen gets in your way).
First you need to figure out what version of CE you are running. You can find this by going to System Properties. Also while you are in System Properties note what processor you are running ( arm, mips ...). If you are running windows ce 4.2 or higher you will pick a cab file out of the wce400 folder. If you are running windows CE 5.0 or higher you will pick a cab file out of the wce500 folder. Note you can't install .net 2.0 on windows ce 4.1 or lower, according to Microsoft documentation, however, I have noticed that the minimum version setting on the cab files is 4.0, so you might be able to hack it.
Like I said before on also the System Properties page is the type of processor you are using. From that select the appropriate sub-folder in either wce400 or wce500. In most of the folders for each processor there should be only one cab file. If there is more than one cab file see if the file name contains wm for windows mobile, wce for windows ce, or ppc for pocket PC and pick the one most appropriate for you.
You can also take the guess work out of this whole process by creating an ini file with the fallowing text and using ceappmgn.exe to pick and install the right cab file for you.

everyone. I am developing the LWF version WinPcap. It is already finished and under internal test currently. A colleague shared a Win7 x64 virtual machine with me remotely. Then I tried to install my new WinPcap installer on it and the machine just got frozen when installing the driver. The strange thing is that only this machine has this problem. I tested my own Win7 x86/x64 and Win8 x86/x64, no this issue.
I seem to encounter an alike problem before, but it is a debug version. My machine got recovered when a kernel debugger like WinDbg or VS2012 was attached. I thought this is a "int 3" problem. But the driver in this installer is a release version. So I don't know if this is because of the same issue. It is difficult to attach that remote machine becasue we are from different countries.
Also this should not be a deadlock issue like NdisWaitEvent waiting for an impossible event. Because I encountered that deadlock before, it only blocked the network part of Windows. Like froze the network properties window, stopped you from rebooting and so on. You can still use the other part of Windows.
So why this frozen problem occurs?
Here is all the code of my driver if you like to read:
https://svn.nmap.org/nmap-exp/yang/NPcap-LWF/packetWin7/npf/npf/
The installer and other info are as below:

The installer only:
https://svn.nmap.org/nmap-exp/yang/NPcap-LWF/installer/winpcap-nmap-4.1.3-NDIS6-1.2.0.exe

I took some time to create a small example project that uses gradle-gae-plugin.
I based it on one of the tutorial projects that google has.
For some reason it fails to run 100% locally (the upload of order fails) and the upload to google appengine fails.
See https://github.com/oakstair/gradle-gae-plugin-tryout
The example project works fine for me with Java 7. This is the specific version I am using:
java version "1.7.0_21"
Java(TM) SE Runtime Environment (build 1.7.0_21-b12)
Java HotSpot(TM) 64-Bit Server VM (build 23.21-b01, mixed mode)
One thing that needs fixing in your build script is the definition of the gaeSdk dependency. That may not be declared within the gae closure. It needs to go in the dependencies configuration block outside of the gae closure.
Running the application with gaeRun works fine for me. I haven't fully tested the upload. Executing gaeUpdate asks me for your password so I assume it's not broken. What is the error you are seeing?
Having set up my Mac and PC per these instructions, I am nevertheless unable to attach to the process running in OS X.
"Unable to attach to the process. A debug component is not installed."
Anyone seen this before? I've Googled it, turned up nothing.
I got the exact same error message on my machine after I had windows update install a security update for Silverlight on windows. I think the root cause is different versions of the silverlight runtime. I recommend doing the following:
Make sure that both windows and mac have the developer runtime installed, and that it is the same version. The latest ones are here:
http://www.microsoft.com/en-us/download/details.aspx?id=36946
After doing that, relaunch the configuration generating program on OSX, generate a new configuration (top button), and then generate a new PC configuration (bottom button).
Close visual studio, run the configuration exe on windows, and open visual studio.
I followed these steps and was able to get remote debugging working again.
I recently inherited a C# Winforms application that communicates with Quickbooks via their QBFC interface. The application contains a reference to the COM Server Interop.QBFC7.dll. The application works fine in our test environment and in several of our client's environments. Although, yesterday when I attempted to install it on a new customer's system I continued to get the following error:
Could Not Load File or Assembly 'Interop.QBFC, Version=8.0.0.87, Culture=neutral, PublicKeyToken=...' or one of its dependencies. The system cannot find the file specified.
I know that we have several customers running this application on various versions of Quickbooks (i.e. Quickbooks Pro, Premier and Enterprise between 2008 and Enterprise 11.0). To my knowledge, this is the first customer that we have attempted to deploy this application that has Enterprise 12.0.
I have attempted the following to resolve the issue with no success:
1) Install the QBFC7_Installer from the Intuit Developer Network Site
2) Install the Quickbooks SDK 10 Installer from the Intuit Developer Network Site
3) Verified that the Interop.QBFC7.dll file is present on the file system.
4) Attempted to manually register the COM object Interop.QBFC7.dll via the command prompt: regsvr32 Interop.QBFC7.dll (This fails as well and windows returns an error stating that it cannot find the object).
Does anyone have any suggestions or feedback about additional things that I can try to resolve this issue? I get the same error on 3 different machines at their site running different operating systems (i.e. Windows Server 2008, Windows 7, and Windows Vista)? I have also tried compiling in both x86 and 64-bit configurations to no avail.
Thanks in advance for any help.
First of all, you should be targeting an x86 build only. The QuickBooks SDK won't work if you target Any CPU or x64. Your main problem, though, is that you are looking for the wrong version of QBFC. Notice the version stamp on your error message:
Could Not Load File or Assembly 'Interop.QBFC, Version=8.0.0.87,
Culture=neutral, PublicKeyToken=...' or one of its dependencies. The
system cannot find the file specified
This is QBFC8, not QBFC7. So you should be able to fix the problem with the QBFC8 installer.
The version of QuickBooks should not make a difference, since QBFC 8 (or 7, for that matter) will work with the 2008 and Enterprise 11 or 12.
You should look into using a setup project to install your application in order to avoid this problem in the future. A setup project should detect the QBFC dependency automatically. Once you see this happening, go to SearchPath property of your setup project and add the MergeModule directory from the SDK that is installed on your machine. Once you do this, you should see that the QBFC and Xerces merge modules are added to your project automatically as dependencies. Of course, you'll also need to update your code to a more recent version of QBFC, but that's probably a good idea in any case.
