It's good to follow up with what solved your problem so others with similar issues can gain from your experience.

Also, it's conventional to name packages with all lower-case letters; following Java programming conventions makes your code easier to understand.

Glad you worked it out!

Thanks for the suggestion DAVID

when i run my application means homepage and leave the field blank then i redirect to the home page with proper error massage
i am redirected to the home page but no message is displayed
here is my homepage

and this my new ActionForm Class

package MyActionFormClass;

import javax.servlet.http.HttpServletRequest;

import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionMessage;

@SuppressWarnings("serial")
public class UserInfoFormClass extends ActionForm 
{
	
	String fName,lName,email,uName,pass;

public String getfName() {
		return fName;
	}

public void setfName(String fName) {
		this.fName = fName;
		
	}

public String getlName() {
		return lName;
	}

public void setlName(String lName) {
		this.lName = lName;
	}

public String getEmail() {
		return email;
	}

public void setEmail(String email) {
		this.email = email;
	}

public String getuName() {
		return uName;
	}

public void setuName(String uName) {
		this.uName = uName;
	}
	public String getPass() {
		return pass;
	}

public void setPass(String pass) {
		this.pass = pass;
	}

public ActionErrors validate(ActionMapping actionMapping, HttpServletRequest req)
	{
		ActionErrors actionError=new ActionErrors();
		if(getfName().length()==0)
			actionError.add("fName", new ActionMessage("error.fName.required"));
		if(getlName().length()==0)
			actionError.add("lName", new ActionMessage("error.lName.required"));
		if(getEmail().length()==0)
		actionError.add("email", new ActionMessage("error.email.required"));
		if(getuName().length()==0)
		actionError.add("uName", new ActionMessage("error.uName.required"));
		if(getPass().length()==0)
		actionError.add("pass", new ActionMessage("error.pass.required"));
		
		
		return actionError;
		
	}

Well, you don't have that key in your resources file, unless you only posted part of it, which wouldn't be very helpful. I wouldn't think that would cause an NPE, though, but you also don't post the stack trace.
