How to import a class, which is not in a package?

Hi all,
I have the following problem:
A class A is not in a package. In another class B, which is in a package (let's say package X) I want to use the class A. Without importing the class A, I get the error "Cannot resolve symbol".
Using the import statement import A; gives the error ". expected".
How can I import that class?
Best wishes to all ...

I think not putting a class in a package is a bad practice. Avoid that.

How to import other class in Flex Builder2?

I use Flex Builder2,I want to import the other class,such as
ascb,like follows:
package {
import flash.display.Sprite;
import ascb.units.Converter;
import ascb.units.Unit;
import flash.events.Event;
public class ApplicationExample extends Sprite {
private var _square:Sprite;
private var _angle:uint;
public function ApplicationExample() {
_square=new Sprite();
_square.graphics.lineStyle(0);
_square.graphics.drawCircle(0,0,2);
addChild(_square);
_angle=0;
addEventListener(Event.ENTER_FRAME,move);
private function move(event:Event):void{
var
converter:Converter=Unit.DEGREE.getConverterTo(Unit.DADIAN);
var angleRadians:Number=converter.convert(_angle);
_square.x=Math.cos(angleRadians)*100+200;
_square.y=Math.sin(angleRadians)*100+200;
_angle++;
ApplicationExample.as is locate in direcotry C:\workspace,and
I put package ascb into directory C:\workspace too,then I run
ApplicationExample.as ,it raise following error:
Description:A file found in a source-path must have an
externally visible definition. If a definition in the file is meant
to be externally visible, please put the definition in a package.
Resource:Converter.as
In Folder:ApplicationExample/ascb/units
Location:line -1
By the way,when I write import ascb.,it should show units,but
it only show util, I guess I may put package ascb into wrong
director,or the ascb don't put the route of Flex Builder2. I don't
know how to do it!
Please give me detail steps to solve above error!
Thanks in advance!

when I put as
import a;
while compiling, it prompt : '.' expected
how to resolve it?
thanksIn J2SDK 1.4, you can only import a class that is in a named package. The compiler is expecting a package_name.class_name;
You do not need to import classes that are in the same package and all classes that do not specify a package name are in the same unnamed package. However you must import classes that are in different packages.

How to import a class that have no package

I have .class archive that i need to use in a web aplication on Tomcat. I put the class in the directory: <webapp>/WEB-INF/classes/.
The class doesn�t have a package, so when i tried to import (..page Import=".....") it, tomcat gave me an error because is looking for a package instead of the class.
then i try to use it without the import and tomcat gave another error because it can�t find the class.
Any ideas??
by the way.. I don�t have the source code, I just have the .class archive..
thank you....

Also, I already found that the class had no package. Then you are out of luck.
As of java 1.4 you can no longer import classes that are not in a package. [url http://bugs.sun.com/bugdatabase/view_bug.do;jsessionid=c85f07c1ce8f344d787b7a5146d68:WuuT?bug_id=4361575 ] Full details here
The only solutions I can think of
1 - get the people who originally gave you the class to package it properly.
2 - Decompile it to java code, Change the java code to put it in a package and recompile it. Depending on the complexity of the class this may or may not be a trivial operation.
Good luck,

A class that is in a package cannot access a class that is not in a package.

Is the plus sign really not available on your keyboard at the place indicated on this graphic (to the right of the L key)? You might need to use shift or alt/option or shift+alt/option.

After "upgrade" to new firefox, bookmarks didn't transfer. Help tells how to import from another browser but not old firefox. Also my anti virus (latest update) apparently not compatible with 4.0 Can I restore my old version

Question
After "upgrading" to new firefox none of my bookmarks are in new bookmarks help topics tell me how to import from another browser but not from previous version of firefox. Another problem is my anti virus ( most up to date) is apparently not compatible with 4.0 liked the old firefox would never have "upgraded" had I known my anti virus wouldn't work. Can I get old version back

Check with Kaspersky as to what versions of Firefox their programs are compatible with. It is up to Kaspersky to keep their stuff up to date as Mozilla releases new versions of Firefox. And if they are unwilling or incapable of doing it, they should inform their customers of such and maybe refund their customers instead of stringing them along.

How to import custom classes from model to view controller in adf?

hi...
i have some custom classes in model layer in adf.
i want to use them in view controller but i cannot import them.
how is this possible?
my jdev version is 11.1.1.5

You normally don't have to do anything special. The view controller project has a dependency to the model project. So simply typing the class name should show you hte option to generate the need import statement for the class.
However, not all classes which reside in the model project should be imported into the view Controller as it might break the MVC pattern.

Have you first compiled Plaf.java and saved it in this directory strucuture

And also have you set your classpath to the parent directory of org folder.
