Error while trying to extract jar file

Question

I am trying to extract a jar file using the following command:

C:\Program Files\Java\jdk1.7.0_25\bin>jar xf C:\Users\...\MyJar.jar

but get the error:

java.io.IOException: META-INF : could not create directory
    at sun.tools.jar.Main.extractFile(Main.java:953)
    at sun.tools.jar.Main.extract(Main.java:877)
    at sun.tools.jar.Main.run(Main.java:263)
    at sun.tools.jar.Main.main(Main.java:1177)

What can it be solved?

Answer 1

It's because you don't have write permissions in C:\Program Files\Java\jdk1.7.0_25\bin.

Try uncompressing it in a different folder or open a console as administrator.

Answer 2

It looks like permission issue.

Try extracting the jar file using WinRAR or 7-zip. you can right click on jar file and select extract to (Where you have write permission) .
