public static synchronized Date getToday()
  {      
        return new Date();
   }

Program B:
=======
...
...
piObj.getContmstr().setInituwrtdt(new DateUtil().getToday());

I'm assuming program A is a class called DateUtil. If so, you can call it like this:

piObj.getContmstr().setInituwrtdt(DateUtil.getToday());

You do not need to use the 'new' keyword when calling a static method. You just use the class name and the method you are calling.

Hope that helps,

but if i remove the "new" in the line, i will haev this problem.

"The method DateUtil() is undefined for the type PropInputServlet

** PropInputServlet is the name of my program B.

Make sure your not writing it as DateUtil().getToday(), it should be DateUtil.getToday(). Also, are you importing your 2nd class? If the class is called DateUtil and is in your package my.package.DateUtil then you need to import it at the top of your page like this:

import my.package.DateUtil;

"static means no need "new"??"

Your right. Static methods or fields are like global variables or functions. You only use the "new" keyword when you are creating a new object.
