Error while creating new user in Oracle 11i EBS

Question

I am getting following error while creating new user. How solve this issue?
“Unable to load java class % specified profile option SIGNON_PASSWORD_CUSTOM. Please verify that the class exists and that it implements the java interface oracle.apps.fnd.security.PasswordValidation”.

Answer 1

Following is the text from Note for Custom Password Validation logic:
Customers who wish to use their own password validation logic may do
  so by writing their own Java classes that implement the
  oracle.apps.fnd.security.PasswordValidation Java interface.  The
  interface requires 3 methods to be implemented:
  1) public boolean validate(String user, String password)
    - This method takes a username and password, and then returns true
  or false, indicating whether the user's password is valid or invalid,
  respectively.
  2) public String getErrorStackMessageName()
    - This method returns the name of the message to display when the
  user's password is deemed invalid (i.e., the validate() method returns
  false).
  3) public String getErrorStackApplicationName()
    - This method returns the application shortname for the
  aforementioned error message.
  After writing the Java class to perform customized password
  validation, the customer must then set the value of the profile option
  SIGNON_PASSWORD_CUSTOM to be the full name of the class.  If, for
  example, the name of the Java class is
  oracle.apps.fnd.security.AppsPasswordValidation, then the value of the
  SIGNON_PASSWORD_CUSTOM profile option must be
  oracle.apps.fnd.security.AppsPasswordValidation.  Note that AOL/J
  will attempt to load this class dynamically.  Hence it is necessary to
  make the class accessible by AOL/J.  This means that in Forms, the
  class must first be loaded into the database using the loadjava
  command.
