Your question is not very clear. I'll assume the variable is declared inside a servlet, because it's bad practice to use Java in a JSP. To be able to share a variable between a Servlet whic forwards to a JSP, you need to set this variable into a request attribute:

String registration = "10-120";
request.setAttribute("registration", registration);

And then in the JSP, you can get the value of the "registration" attribute using the JSP EL:

<input type="text" name="registrationUpdate" value="${registration}" maxlength="50" />

You should read the Java EE tutorial: http://docs.oracle.com/javaee/5/tutorial/doc/bnadp.html
