Where is the class CISrefnoApp.classcls?It's required on the classpath.

[naushad]

there is no file called .classcLs in my entire system and it was a typing mistake.
I re-typed it java -Xmx1024 CISrefnoApp.class and getting the same error again
and this class is residing in C:\Users\Administrator\Documents\NetBeansProjects\ CISrefno\build\classes\cisrefno

[r035198x]

When running a Java class, you don't add the .class at the end of the class name.

received the following message when i typed java -Xmx1024 CISrefnoApp

got d message "Exception in thread "main" java.lang.noclassdefounderg. CISrefnoApp <wrong name :cisrefno/CISrefnoAppp

difference here is it says wrong name

[r035198x]

As you can see from the message, your class needs a class called CISrefnoApp.classcls and it can't find it.
