how do i import a compiled file in current file

[roomy iqbal]

Hi

Thanks guys you have been very helpful in last problem now i have got another problem. I have got 2 files Book.java and ShoppingServlet.java. I have compiled Book.java and it has generated a class file. Shopping sevlet uses Book.java items. here is how the code looks like

Book.java

   
package ebookshop;
public class Book {
 ..............
}
 

ShoppingServlet.java

 
package ebookshop;
import java.util.*;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import ebookshop.Book;
public class ShoppingServlet extends HttpServlet {
public void init(ServletConfig conf) throws ServletException {
super.init(conf);
}
 ....................
 

Now when I execute this it gives me errors related to Book.java which is already compiled and its class file is available. I have tried to put it in -cp parameter as well here is the kind of error i get

 
ShoppingServlet.java:6: cannot find symbol
symbol  : class Book
location: package ebookshop
import ebookshop.Book;
                ^
ShoppingServlet.java:83: cannot find symbol
symbol  : class Book
location: class ebookshop.ShoppingServlet
private Book getBook(HttpServletRequest req) {
 .................
}

You need to find where the Book class is. Are you used to compiling classes with a package declaration?

If you search through beginners' you find old threads.

This one, where somebody else seems to have the same problem.

This one where the late Stan James (instanceof SideKick) links to a tutorial about packages.

Somebody who had a very simple answer to compiling two files.

At least two ways to compile files in packages.

Make sure you have the servlet packages installed. Try compiling both files simnultaneously. Tell us whether it worked.

Also note that within a package "ebookshop", it is not not only unnecessary to import any other class in package ebookshop, but in fact it might be part of the problem you're having. The import statement doesn't belong there at all.

thanks i managed to fix it using the links that you guys provided. I just compiled them together and it worked

javac -Xlint Book.java SoppingServlet.java
