About this task
![[16.0.0.4 and later]](../ng_v16004plus.gif)
Java SE 8 is the recommended Java SDK because it provides the latest features and security updates. You can install it by installing the IBM SDK, Java Technology Edition, Version 8 package to the package group that contains WebSphere Liberty.
New: Installation Manager now supports two types of Java SDK offerings:
- Common IBM Java SDKs: These offerings, which are denoted by com.ibm.java.jdk IDs, are available for the latest Java versions. Because these offerings do not follow the WebSphere fix pack schedule, you can receive Java security updates faster, as they become available. These offerings are also used by WebSphere Application Server traditional V9.0.
- WebSphere Java SDKs: These offerings, which are denoted by com.ibm.websphere.liberty.IBMJAVA IDs, are available for older Java versions. Updates to these offerings are delivered according to the WebSphere fix pack schedule.
The following table lists the Java SDK offering names and IDs.
Java SDK offering name | Offering ID |
---|---|
IBM SDK, Java Technology Edition, Version 8 | com.ibm.java.jdk.v8 |
IBM SDK, Java Technology Edition, Version 7 Release 1 | com.ibm.java.jdk.v71 |
IBM WebSphere SDK, Java Technology Edition, Version 7 | com.ibm.websphere.liberty.IBMJAVA.v70 |
IBM WebSphere SDK, Java Technology Edition, Version 6 | com.ibm.websphere.liberty.IBMJAVA.v60 |
Note: Liberty Version 8.5.5 supported the
com.ibm.websphere.liberty.IBMJAVA.v80 and
com.ibm.websphere.liberty.IBMJAVA.v71 offerings. Although you can continue to
install these offerings, consider installing the common Java
SDK instead for both new and existing installations. Note that these WebSphere
Java SDK offerings cannot be used with the versionless Liberty offerings, such as
com.ibm.websphere.liberty.BASE, which were introduced in Version 9.0. For these Liberty offerings, you must install the IBM
Java SDKs.
The Java SDK offerings are installed by using the standard Installation Manager procedures. The architecture of the Java SDK offering is automatically selected based on your operating system.
