问题
When I run my BlackBerry project in Eclipse, I get the following error:
Error: Cannot run program "jar": CreateProcess error=2, The system cannot find the file specified
How is this caused and how can I solve it?
回答1:
you can solve this problem by following setting
Right Click My Computer -> Select Properties-> Select AdvancedSystem Settings Tab -> Environment variables Click on new button and Add
Variable Name : JAVA_HOME
Variable Value : C:\Program Files\Java\jdk1.7.0\
note jdk not jre
回答2:
Finally I get the solution .copy the jar.exe from java bin folder and paste to the jre bin folder.
回答3:
I tried several of the posted methods, the important step seemed to be setting the correct system path (the "Path" environmental variable) to have included a folder that pointed to the relevant jar.exe. The variable changed from X to X + ;C:\Program Files\Java\jdk1.7.0_03\bin; you need to make sure the jdk folder part is relevant to your version, which I overlooked.
The reason for my answer is to add the step I missed; which is to restart Eclipse! I tried running it a few times, but after closing and reopening it the project packaged correctly. It might not have been obvious to do this.
回答4:
i think you need to set jarfile path.
回答5:
From the BlackBerry Support Forums:
first thing is to check that the JDK is installed, and that the PATH is set correctly. Open a command line window, and run the "jar" command.
回答6:
- Set the Environment variable correctly (under path set till jdk->bin)
- In your Eclipse Installed JREs make sure you are pointing till JDK folder and not JRE
回答7:
The Solution is: Open My computer, right click > select properties > go to advanced > go to System environment variables > under PATH add this one:
c:/Program Files/Java/jdk1.7.0_03/bin
Close and reopen Eclipse and thats it...
NOTE: jdk1.7.0... is for the java version you have installed on your computer
回答8:
This error comes because of Jdk1.7. So try 1.6 and set path to bin folder.
It works for me...
回答9:
I was developing an app for BB JDE 5.0 and I had the java JDK 1.7. I was going crazy because I tough everything was ok. Then I realize that for JDE 5.0 I needed JDK 1.6. Installed it from here Java SE Development Kit 6 Update 45 changed the environment path and my problem was solved!. :)
回答10:
Adding C:\Program Files\Java\jdk1.8.0_131 to JAVA_HOME and C:\Program Files\Java\jdk1.8.0_131\bin to Path in System Variables within Environment Variables wasn't sufficient.
Turns out, you need to add those two variables and their respective values to both user and system variables within environment variables.
I added the following to BOTH User variables as well as System variables in Environment Variables: Variable: JAVA_HOME Value: C:\Program Files\Java\jdk1.8.0_131
Variable: Path Value: C:\Program Files\Java\jdk1.8.0_131\bin
That worked for me !
回答11:
This worked for me: Project JDE 5.0 OS: Windows 8.1 x64
This PC > Properties > Advanced System Settings > Environment Variables: Added the following: Path: C:\Program Files (x86)\Java\jdk1.7.0_25\bin;C:\Program Files (x86)\Java\jdk1.7.0_17\bin;C:\Program Files (x86)\Java\jre7\bin
I know the above is similar but thought id post what worked for me anyway as it reinforces the above answers :)
NB to restart eclipse.
