Class.forName is giving ClassNotFound Exception

Question

I am using the following code ::

String className  = "SmsHelper"
Class c = Class.forName(className); 

And I am getting the following

stackTrace ::

 inside main java.lang.ClassNotFoundException: SmsURLHelper
    at java.net.URLClassLoader$1.run(Unknown Source)
    at java.security.AccessController.doPrivileged(Native Method)
    at java.net.URLClassLoader.findClass(Unknown Source)

    at java.lang.Class.forName0(Native Method)
    at java.lang.Class.forName(Unknown Source)
    at com.tcs.sms.actions.SmsUtil.invoke(SmsUtil.java:131)

Note : The SmsHelper class is present.

Please suggest if I have missed any thing.

Answer 1

Use the fully qualified name.

Example:

Class.forName("com.yourownpackage.SmsHelper"); 

Answer 2

Please write the Class name along with its package name(in which your class resides) as a String in the forName method. Here is the sample to use:

String className  = "com.testpackage.SmsHelper";
Class c = Class.forName(className);
