Extracting Specific class file from EAR file in Unix

Question

I have an ear file which contains around 20 jar files. Now there is a specific jar file in this EAR say jar 1 which contains application class files.

Now I want a single line command in unix which can extract a particular class file from that jar (jar 1 in this case) present inside EAR.

Answer 1

I found a way to do it in 2 stages:

1. Find the file you want:

   jar tvf file.ear | grep file_you_want.abc
   

   You will get the file you want with its path.

2. Extract it:

   jar xvf file.ear path/to/file/file.abc
