Java JDK and JRE

[rerwin]

Attached is the result of my combining parts of 01micko's get_libreoffice and and uten's sfs-java.sh scripts to form get_java. The former set provides the RAM/HD requirement determination and the sfs load part. Uten's is everything else except my user input function.

The package also includes a profile code file and initialization script intended to become part of puppy and independent of the SFS files, which need contain only the Oracle JRE components. Those scripts also support JDK SFS files, although get_java itself does not currently build them. They also support JRE SFS packages created my other means, including shinobar's and OscarTalks' SFS files and those built from uten's sfs-java.sh. The profile code detects the jre1... directory if present in /opt, /usr/java, /usr/local or /usr/local/java. (Those are the places I am aware of, although I can add more if there are any.) Although the scripts will override any in an SFS file, JRE pet installations containing their own profile or init script may interfere with them -- unless they are installed before installing get_java.

The user is given the options of downloading either the 32-bit or 64-bit version of the latest JRE, as well as building from already downloaded archive (tarball) files. Get_java looks for those files in /tmp, /root and /mnt/home, up to one subdirectory level deep.

Once the SFS file is built, the option of loading it immediately is offered. If the file is loaded, the supporting linkages are put in place, making the new JRE ready for use immediately. Otherwise, the links are added at the bootup following loading by the BootManager or sfs_load.

Feedback very welcome.

EDIT: I replaced the package after the first download, to add the automatic link installation and remove an extra file. Also added detection of Barry's jdk location.

Hi, in Appril (Quirky), I placed the JDK at /opt/jdk. It is the whole thing, as downloaded from Oracle, just copied as-is to /opt/jdk.

Quirky does not use SFSs, so it is a PET package.

I'm away from home right now, so can't check, but in the PET I did set a couple of environment variables in /etc/profile.d/jdk, I think one was JAVA_HOME.
Um, will have to check, but think also added to the PATH variable, so bin/java is in the path.
