| 1 | Self-extracting jre instructions

| 4 | 1. You need 7za and 7zCon.sfx from the p7z-essentials folder to generate the self-extracting jre from the jre
|
|---|
| 5 |
|
|---|
| 6 | On a mac, you need to compile these two binaries up yourself by downloading the p7zip source code from online http://p7zip.sourceforge.net/. Compile the source code by first runnng "make" to build the 7za, then run "make sfx" to build the 7zCon.sfx binary.
|

| 7 |
|
|---|
| 8 | 2. Need the jre for your java version.
|
|---|
| 9 | Java 8 should be used for Expeditee.
|
|---|
| 10 | The jre should be extracted into a folder named jre. Also, don't make it a tar file for Expeditee. (Greenstone expects the jre to be tarred up first.)
|
|---|
| 11 |
|
|---|
| 12 | 3. Run:
|
|---|
| 13 | ./p7z-essentials/7za a -sfx -mx=9 jre_bin[_x64] /path/to/your-jdk-version/jre
|
|---|
| 14 |
|
|---|
| 15 | * -m0=lzma2 is already done automatically, setting the compression mode to lzma2.
|
|---|
| 16 | * -mx=9 set its to ultra (compression? speed?)
|
|---|
| 17 | * the output file name expected by the release-kit is jre_bin for 32 bit linux, jre_bin_x64 for 64 bit linux
|
|---|
| 18 | * -sfx indicates that it will generate a self-extracting binary out of the input file
|
|---|
| 19 | * the "a" indicates it will add the files from the input folder (the /path/to/your-jdk-version/jre in this case) to the output file

| 23 | To get the JRE for a Mac, do one of the following:
|
|---|
| 24 |
|
|---|
| 25 | A. Now (at least since jre v 1.7.0_79) the Oracle site has a JRE for Macs available for download as dmg and tar.gz files. If this is available:
|
|---|
| 26 |
|
|---|
| 27 | 1. Download the JRE.dmg or JRE.tar.gz for the java version you want and extract it.
|
|---|
| 28 | 2. From the extracted contents, the folder you want is jre<version>.jre/Contents/Home. Rename this Home subfolder to "jre".
|
|---|
| 29 | 3. Tar it up and create the self-extracting jre (the final step of the instructions above):
|
|---|
| 30 | ./p7z-essentials/7za a -sfx -mx=9 jre_bin_x64 jre.tar
|
|---|
| 31 |
|
|---|
| 32 |
|
|---|
| 33 | B. If no JRE.dmg or JRE.tar.gz for Mac is available:
|
|---|
| 34 |
|
|---|
| 35 | 1. Download the JDK.dmg for the java version you want.
|
|---|
| 36 | 2. Open the dmg, drag the .pkg out to another folder.
|
|---|
| 37 | 3. Extract the pkg using: xar -xf <file>.pkg
|
|---|
| 38 | 4. Another couple of pkgs should appear, these are actually fake folders (like .app folders)
|
|---|
| 39 | 5. The one you want is the jdk<ver>.pkg. Rightclick > Show package contents to view its contents.
|
|---|
| 40 | 6. Then double click on the Payload item to extract Payload. Alternatively, since it's just a tarfile, you can do
|
|---|
| 41 | tar -xf jdk180.pkg/Payload
|
|---|
| 42 | 7. You get a Contents folder, then browse to Contents > Home > jre. That's the folder you want.
