Hi to all,
I am new to JMS concept in java.I have downloaded a example jms program in the site. So i have mention the classpath the java path.The jms program is compiled fine and class file also gernerated.
The problem is when i run the normal java program or any other java program the following error is occured.
JAVA_HOME=/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0/
CLASSPATH=/home/prem/j2ee/j2sdkee1.3.1/lib/j2ee.jar
I am using the fedora redhat.
Error Message:
java ex_sample
Exception in thread "main" java.lang.NoClassDefFoundError: ex_sample
Caused by: java.lang.ClassNotFoundException: ex_sample
at java.net.URLClassLoader$1.run(URLClassLoader.java:217)

at java.lang.ClassLoader.loadClass(ClassLoader.java:268)
at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:336)
This error is cleared when i remove the classpath variable .
CLASSPATH IS REMOVED.
1.Can any one say why this error is appearing ?
2.If i am not mentioned the classpath the JMS program is not executed?
Thank you,
With Regards,
Prem
