Not sure, but check the field named "pic" in RegistrationActionForm for the valid data type. Its seems like your assigning a wrong data to the "pic" property !!

[Hari adya]

triied all that...... there are the getter and setter methods.....

see, there is a JSP, has an input type as FILE
ActionForm contains FormFile getter and setter method
ActionClass uses getPic() method to get the properties of the file.......

If you want, ill paste the code

Have you googled:
FormFile in struts + java.lang.IllegalArgumentException
