To install the documentation bundle using the zip utility:
C:> unzip j2sdk-1_3_1-doc.zip
You can also install the .zip file using the Java 2 SDK's jar utility:
C:> jar xvf j2sdk-1_3_1-doc.zip
Note: If you are using another tool that doesn't preserve
path names by default, be sure to specify that path
names be preserved. For example, if you are using
pkunzip, specify -d:
C:> pkunzip -d j2sdk-1_3_1-doc.zip
