Error installing IMlet....Emulator Error

Question

Windows 8.1 (I have now also tried it on Windows 7)
Java ME SDK 8
Netbeans 8
Since downloading Netbeans a few days ago I've been having persistent problems. It's very slow and the the emulator starts up less than half the time. MosT of the time
I get An error once the emulator opens and it's about the begin running the program. It says:
Error Installing IMlet: See Device Log for Details.  (see attachment)
The FATAL error message in the log is as follows:
[03:55:09.401]  FATAL - lkit.ui.actions.AmsExecInstall - Unknown error: invalid url: file:///C:/Users/Kevins Home/Desktop/GPIOLEDTest/dist/GPIOLEDTest.jad    (see attachment)
This problem also occurs on my girlfriends MAC using the same code + setup.
There's very little online material that seems to be relevant.
Would love to figure out what's wrong so I can finish this course: Develop Java Embedded Applications with a Raspberry Pi
Thanks in advance

Answer 1

I'm don't know what is causing this problem.  Hopefully one of the Oracle folks can chime in on this. 
Let me review a few things with you just to make sure your problem isn't something obvious...
1.  You have all the software prerequisites installed: all the Java ME version 8 release software installed listed in the first few videos of lesson 1.  This means not version 7, not pre-release, not beta.  Make sure you have installed the exact versions of the software Tom listed in the video. 
2.  You have netbeans 8 installed.
3.  You have putty installed
4.  You have enabled ssh and a static IP address in the RPi
5.  You can use putty to SSH to the Pi using your static IP addresspi
6.  When you SSH to the Pi, it asks for your login, which is 'pi', and your password, which is 'raspberry''
7.  Once you login to the pi you navigate to the AMS bin folder using 'cd javame8/bin'
8.  Then you issue the command 'sudo ./usertest.sh' to start AMS.  Note you must use sudo.
9.  Your RPi will respond Java is starting. Press Ctrl-C to exit. 
10. DO NOT press Ctrl-C
11. Go to the folder where your Netbeans projects are stored.  On my computer it is c:/Users/Administrator/MyDocuments/NetBeansProjects.
12. Remove all projects from there.  Either delete them or move them somewheres else for now. I want to make sure the project we test with has not been modified.  Best way to do that is start out with no projects.
13. Startup Netbeans.
14.  Verify there are no projects in Netbeans.  There shouldn't be any because your NetBeansProjects folder should be empty.
15.  Download GPIOLEDTest from the Oracle link in Lesson 1.  It will download a zip file.  Do not open it.
16.  In Netbeans, select File / Import Project / From Zip...
17.  Navigate to the GPIOLEDTest.zip.  I think it will be in your Downloads folder.
18.  It should now be installed as the only project in Netbeans. 
12.  There will be a Device Connection Manager in the system task bar at the lower left of Windows
13. Clicking it shows there is a connection to the static IP address of your RPi and it shows a status of Connected
14. Run the project. It should install and run.
