Chapter 2: Preparing for and Maintaining Java in the Database

Installing compressed JARs

You can also install a compressed JAR file if you first expand the compressed file using the x option of the jar command. In this UNIX example, abcPackage is a compressed file.

Place the compressed JAR file in an empty directory and expand it:
```
jar xf0 abcPackage.jar
```
Delete the compressed JAR file so that it won’t be included in the new, uncompressed JAR file:
```
rm abcPackage.jar
```
Create the uncompressed JAR file:
```
jar cf0 abcPackage.jar*
```
