Blackberry Eclipse plugin and emulator - java

I installed the following installation packages to develop Blackberry apps using the included emulators. I first installed them on a MacBook Pro, virtualizing Windows 7 x86 with VMware. Everything worked fine; I created a quick HelloWorld app and it compiled and ran successfully in the emulator. I did no other configuration. I installed the same app on my desktop PC with Windows 7 x64. I installed the exact same items. When I choose to run with the Blackberry Emulator, nothing happens. Any ideas?
Here's the file list:
BlackBerry_JDE_PluginFull_1.0.0.67
(This includes Eclispe)
jdk-6u18-windows-i586

Did you install the same 32-bit version on both your virtual and desktop versions?
If so, I know the 32-bit version /should/ work on Win7 x64, but is it maybe not compatible? Do you need to just get a 64-bit version for your desktop?

Solution
I removed JDK and the JDE Blackberry plugin.
I reinstalled JDK 6.
I reinstalled the JDE Blackberry plugin into a different directory other than Program Files. So I installed it at c:\rim\eclispe
I started up eclipse and opened my workspace, started the simulator and it finally started and worked.

How to use an SDKMAN jdk for window applications on mac

I've recently installed a fresh Mac OS and installed java using SDKMAN but no windows apps recognize the jdk throwing a java not installed error. Trying to install NetBeans using the .pkg throws a similar error.
Meanwhile, all terminal apps like gradle have no problem with the JDK that was installed using SDKMAN.
How can I use the jdk installed with SDKMAN with windowed apps in Mac?
Checking this answer I've solved it by temporarily installing a similar Java in question through the .dmg file. After that, I've installed Netbeans 14 through the .dmg file as well.
Once NetBeans was installed, I deleted the Java installed through the dmg to manage all my JDKs through sdkman. Since sdkman sets java_home, NetBeans continued to work without a problem.
For some reason, NetBeans installer doesn't detect the current java by the java_home environment but through something else. But NetBeans works without a problem.

Can not acces to \\$wsl WSL - Intellij IDEA can not reach JDK

My Windows installed Itellij IDEA can't reach JDK from Ubuntu (Ubuntu installed on WSL). Durning running app, I got this problem:
And I can not reach \$wsl in Windows run (Start button + r).
UPDATE: WSL is now supported and it should work just fine out of the box.
Original answer from 2020:
IntelliJ IDEA has no support for the WSL JDK on Windows at the moment. Please use the locally installed JDK for Windows instead.

Xamarin Forms Previewer Not Working for Android in Visual Studio Due to Java Version

I am running...
Visual Studio Community 2017 15.0.0+26228.12
Xamarin 4.3.0.795 (aece090)
Xamarin.Android SDK 7.1.0.43 (3a62f1e)
Running the Forms Previewer for the iOS platform works fine, but once I select the Android platform the following prompt shows on the preview window:
"Something went wrong. Unsupported version of Java detected. The previewer recquires a 64-bit version of Oracle Java JDK 8 (1.8) or higher. Please install it and then set the Java JDK location in the Xamarin Studio or Visual Studio preferences."
I have installed the most recent Java Development Kit (Java SE Development Kit 8u121). It's located in the default location C:\Program Files (x86)\Java\jdk1.8.0_112 and I have pointed it succesfully from with in Visual Studio in Tools->Options->Xamarin->Android Settings->Java Development Kit Location.
I'm not sure what else to do as I have followed the on screen prompt and installed Java JDK 8 multiple times.
Thanks for any suggestions ahead of time!
When you're on Oracle's JDK download page, you need to choose the x64 JDK instead of the x86 JDK. (After installing the 64 bit JDK it should be in C:\Program Files\ not C:\Program Files (x86)\

trouble running eclipse from usb

I am trying to run Eclipse Kepler from a usb drive. It will work when coding but when I come
to run the program it shows
error = 216. This version of %1 is not compatible with version of windows you are running.
Eclipse runs fine at home (windows 8 64bit Java 7) but the issue happens at college (Windows server 32bit java 6) Can anyone shed any light on possible issues please.
The JDK and JRE are installed on the USB device and running Java 7. 32 bit Eclipse is installed to USB also. Is it even possible to run java and eclipse as standalone from a usb?
The error code 216 generally means that there is a problem in the 32/64 bit version mismatch between your applications or OS.As you say your eclipse and OS is 32 bit could you please also check if the JDK you are using is 32 bit ?

Unable to install ADT plugin in Eclipse?

I did everything in Windows XP 32bit-with 4GB RAM, but thought why not install all applications on my other computer with 8GB RAM and Windows 7 loaded in it.
I installed everything (relevant 64-bit software : Java SDK-64 bit, Eclipse-64bit and Android SDK) in that Win 7-64 bit, except 1 thing in Windows 7 - 64bit. Even Android is loading fine on the emulator.
But when I am installing the ADT plugin in eclipse from Help > Install New Software > https://dl-ssl.google.com/android/eclipse/ then only 2 options are coming, and eventually the setup fails with showing the error that
Cannot complete the install because one or more required items could not be found. Software being installed: Android Hierarchy Viewer
16.0.1.v201112150204-238534 (com.android.ide.eclipse.hierarchyviewer.feature.group
16.0.1.v201112150204-238534) Missing requirement: Android Hierarchy Viewer 16.0.1.v201112150204-238534
(com.android.ide.eclipse.hierarchyviewer.feature.group
16.0.1.v201112150204-238534) requires 'com.android.ide.eclipse.ddms 0.0.0' but it could not be found
I did everything correctly on Windows XP, but I am getting this problem on Win 7 - 64bit.
Can someone please let me know how to resolve this problem and successfully install the ADT plugin in Eclipse on Win 7 - 64 bit.
Thanks.
Change https://dl-ssl.google.com/android/eclipse/ to http://dl-ssl.google.com/android/eclipse/ .
