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 prerequisite hardware and 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
Linux® POWER™ platform,
the 32-bit and 64-bit JDKs are typically installed to different locations,
for example, the 32-bit JDK is located in
/opt/IBMJava2-ppc-142 and the 64-bit JDK is located
in
/opt/IBMJava2-ppc64-142.
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 prerequisite hardware and software.
