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.
For further information
about using a JDK see Checking optional software.
