SUMMARY:
This Solution applies to SonicMQ Version 4.0 on UNIX. You might see the following message when trying to run the SonicMQ samples using SonicMQ.sh:
java.lang.NoClassDefFoundError: javax
aming/Referenceable
EXPLANATION:
When you install SonicMQ Version 4.0 on UNIX in console mode, you will find that although starting the SonicMQ broker works fine, trying to run one of the examples (for instance, the Chat example) found in the $SONICMQ_HOME/samples directory using the SonicMQ.sh script, produces the following stack trace:
# ../../SonicMQ.sh Chat -u test
Exception in thread "main" java.lang.NoClassDefFoundError: javax
aming/Referenceable

SOLUTION:
The problem is that within SonicMQ.sh, the archive containing the javax
aming package is not included in the classpath.
Adding:
$SONICMQ_LIB/jndi.jar
to the line for setting the environment variable:
SONICMQ_CLASSPATH
within the script SonicMQ.sh, solves the problem since it contains the classes for the javax
aming package.
Example:
SONICMQ_CLASSPATH=$SONICMQ_LIB/sonic_Client.jar${ps}$SONICMQ_LIB/jndi.jar${ps}$SONICMQ_LIB/gnu-regexp-1.0.6.jar${ps}$SONICMQ_LIB/jaxp.jar${ps}$SONICMQ_LIB/xerces.jar${ps}$SONICMQ_LIB/swingall.jar${ps}$SONICMQ_SSL_LIB${ps}$SONICMQ_LIB/tools.jar
