To use any Java language application described in this book, including
the JMS postcard application, you must have a Java Runtime Environment (JRE)
installed. For further information about supported JREs, see
Checking optional software in this book. To ensure that
WebSphere® MQ installation
can use the installed JRE, ensure that the location of the JRE is set in your
PATH environment variable.
See the documentation accompanying your JRE
or JDK to find out where the JRE or JDK will be installed to.
On
AIX,
the 32-bit and 64-bit JDKs are typically installed to different locations,
for example, the 32-bit JDK is located in
/usr/java14/bin and the 64-bit JDK is located
in
/usr/java14_64/bin.
Ensure that the PATH variable is correctly set, to use the JMS Postcard application
you need to use a 32-bit JDK. You can check the version installed using the
following command:
java -version
For further information
about using a JDK see Checking optional software.
