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>-<fix_pack>.zip
file, available from IBM Fix Central. 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
-
Download the IBM SDK, Java Technology Edition, Version 8 ZIP archive file by following the link from IBM
Java SDKs for WebSphere
Liberty.
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.
What to do next
After you verify that IBM SDK, Java Technology Edition, Version 8 updated successfully, delete the Java backup directory.
