How To Install Java In Puppy

There are two main ways to install java. Installing the JDK and the JRE. The JDK is the Java Developers Kit, it contains all the tools necessary to compile java programs. Most people only need the JRE, which is the Java Runtime Environment. Both the JRE and the JDK allow you to run Java programs.

Installing the JDK (only for developers) with GuestToo's installer

You only need the JDK if you are a developer and want to compile Java programs. If you just want to run Java programs, you only need the JRE which is smaller.

I did install the JDK on Puppy. As far as I remember, I did the following.

1) Went to http://packages.slackware.it∞ and downloaded jdk-1_5_0_09-i586-1.tgz

2) created directory /tmp/java and moved jdk-1_5_0_09-i586-1.tgz into that directory. Then opened terminal window in that directory (in ROX, just press ` ) and said gunzip jdk-1_5_0_09-i586-1.tgz and
tar -xvf jdk-1_5_0_09-i586-1.tar

3) moved the folder /tmp/java/usr/lib/jdk1.5.0_09 into /usr/lib/ (I did it using ROX; I do not know how to copy folders from the command line; perhaps cp -ra but I am not sure. In ROX you just drug and drop)

4) moved the file /tmp/java/install/doinst.sh to / and then opened the terminal window in / and said:
sh doinst.sh
(read doinst.sh before doing it)

5) Following the instructions in the file /tmp/java/etc/profile.d/jdk.sh I added these lines to the file /etc/profile.local :

export JAVA_HOME=/usr/lib/java
export PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin
export MANPATH=$MANPATH:/usr/lib/java/man

Then, if you also want to install the java plugin for the browser, read the instructions here:

These are instructions to install Sun's Java 1.5.0_02 in Puppy Linux (run time only)

I've just installed the current Java Runtime Environment (1.6.0.02) into Puppy 2.17.1 (with WhoDo's EZPup 2.1.7R2) directly from Sun, no dotpup involved. Here's the procedure. I composed this so a French-speaker can translate it using Babelfish:
