I/O Error: Cannot run program "jar": CreateProcess error=2, The system cannot find the file specified

why is that error, how to resolve???

[ankityadav4u]

and more, this process succeed if i delete 1 recently added class......

Open up a command prompt and type "jar" in there. If you get a file not found error then you need to check your PATH i Environment Variables and make sure you have one pointing to the location of jar.

[ankityadav4u]

location of which jar file??

[jprofitt · Accepted solution]

The file jar.exe. For exampe, I have a copy of it in C:\Program Files (x86)\Java\jdk1.6.0_24\bin

[ankityadav4u]

thnks it worked............ but can u tell me what was the reason, as the project was running fine earlier, but after adding 1 file it stucks........... does it not need jar file earlier,??? y??

I could be completely wrong about this (someone correct me if I am) but I think that it has to do with when it needs to split up the compiled files. Adding that extra class probably put it over the edge of where it had to do so.

I think the most common cause is the length of the command line passed to JAR.EXE from the RAPC processs...if there are too many files in the build, the generated command line gets truncated.

ya solved my problem by adding system variable path to jdk bin folder

[leewilliams]

Iv done all of the above and still get the error grrr!

I put this in my system path

C:\Program Files\Java\jdk1.5.0_22\bin

where the jar.exe is but it still displays:

C:\Projects\Rim\qrReader\src\com\usingnfc\qrReader\Mainscreen.java:41: Warning!: member data 'MultiFormatReader mMultiFormatReader' not required in class: com.usingnfc.qrReader.Mainscreen
I/O Error: Cannot run program "jar": CreateProcess error=2, The system cannot find the file specified

along with ALOT of the same lines!!

any ideas cause it is driving me up the wall!
