If you installed Liberty with IBM® SDK, Java™ Technology Edition, Version 8 by extracting a ZIP archive
file, you can update the Java software development kit (SDK)
to incorporate Java service releases and interim
fixes.
About this task
The directories in the following procedures are based on Liberty installations that were
installed by extracting a wlp-webProfile7-java8-<platform>-<architecture>-<version>.zip
file, available from IBM Fix Central or WASdev.net. If you separately installed or moved the IBM
Java SDK to a different location, you can update the SDK by
replacing the files at their current location.
Procedure
For Version 8.5.5.7 or later:
- Update the Java SDK in a Liberty ZIP archive
installation.
- Download the IBM SDK, Java Technology Edition, Version 8 ZIP archive file from IBM Fix Central. If you are applying a Java
service release or interim fix that is associated with a certain APAR, see the APAR text for
download information.
- Extract the Java SDK ZIP archive file to a local
directory.
- Back up the wlp/java/java directory in your Liberty installation by
renaming the folder. For example, rename the wlp/java/java directory to
wlp/java/java_backup.
- Copy the sdk folder from the directory where you extracted the Java SDK ZIP archive file to the wlp/java
directory. Rename the new wlp/java/sdk directory to
wlp/java/java.
For Version 8.5.5.6 only:
- Update the Java SDK in a Liberty ZIP archive
installation.
- Download the IBM SDK, Java Technology Edition, Version 8 ZIP archive file from IBM Fix Central. If you are applying a Java
service release or interim fix that is associated with a certain APAR, see the APAR text for
download information.
- Extract the Java SDK ZIP archive file to a local
directory.
- Back up the wlp/java directory in your Liberty installation by renaming the
folder. For example, rename the wlp/java directory to
wlp/java_backup.
- Copy the sdk folder from the directory where you extracted the Java SDK ZIP archive file to the wlp
directory. Rename the new wlp/sdk directory to
wlp/java.
- Copy the java.env file from the wlp/java_backup backup
directory to the wlp/java directory.
What to do next
After you verify that IBM SDK, Java Technology Edition, Version 8 updated successfully, delete the Java backup directory.
