About importing class libraries?

I want to develop a webmail project,so I must use the javax.mail.*,but when I build a new project by J Bulider 5,I can not import those class,why?the same project is when I develop an common project,I can import javax.servlet.*, but when I build a web project,it do.why????thanks

Presumably you mean you can't compile it.
There is some obscure way that you have to include the jar in the IDE that you are using. You can wait until someone provides that or search in the forums for JBuilder and find one of the previous posts that explains how to do it.

Confused about import iPhoto Libraries Aperture 3.2

When I first purchase Aperture 3.2.3 back in May I had many iPhoto librarys split out by year. I wanted an integrated view so when I imported them to Aperture I chose the "leave iPhoto library in place" option. That may not be the exact wording. I was under the impression that this meant that Aperture would point to those libraries, but not duplicate them. I'm not so sure of that now. My Aperture library is around 25GB. My iPhoto libraries add up to at least 120GB.
I have upgraded to Aperture 3.4.2. I know about the library switching option, but I still want an integrated look at all my photos in one place. I got Aperture so I didn't have to do the iPhoto library switching I was doing.
Yesterday I spent a good amount of time deleting a bunch of extraneous photos I had from a project I did throughout 2011. My Aperture library shrunk 1GB. The iPhoto library didn't change size. That makes me think that the import actually put the files in the Aperture Library.
So, now I'm not sure what's going on. Is there a way to see which libraries are pointed to the original iPhoto libraries?

Is there a way to see which libraries are pointed to the original iPhoto libraries?
When you select an image in the Aperture library and use the command "File > Show in Finder" you can see the location of the original image file. If this points into a folder inside an iPhoto Library, you are really referencing the iPhoto Library. But if the command "Show in Finder" is disabled for an image, it is managed inside the Aperture library.
But frankly, I do not think it is a good idea to use Aperture to delete images inside your iPhoto libraries. Ypur iPhoto Libraries may be corrupted this way.

Problem about importing class

Hello,
i have this code.

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
xmlns:my="components.*" width="100%" height="100%">
<mx:Script>
<![CDATA[
import lib.User;
public var u:User = new User();
trace(u.say("hello world"));
]]>
</mx:Script>
</mx:Application>

package lib{
public class User{
public function say(s:String):String{
return s;
i get this error:
1120 Access of undefined property
Why??
thanks so much

You have this Script block in your code:
<mx:Script>
<![CDATA[
import lib.User;
public var u:User = new User();
trace(u.say("hello world"));
]]>
</mx:Script>
The trace statement is just "floating" in there - it must be
in a function. When do you want this trace executed? For example,
if you want to display it when the Application dispatches its
creationComplete event, then add a creationComplete event handler
to the Application tag and then write the function to handle the
event in the Script block:
<mx:Application ... creationComplete="initApp()">
<mx:Script>
<![CDATA[
import lib.User;
public var u:User = new User();
private function initApp() : void {
trace(u.say("hello world"));
]]>
</mx:Script>
Now the trace statement appears in a function so you will not
get the error.

Importing classes in Jsdk 1.4.2

Hi,
I have two swing applications that run perfectly well when compiled and run. But then I am trying to include these two programs as two tabbed panes in a third program.
I try to import classes from the other two programs using a simple import statement. But when I compile it the compiler return an error statement.
I tried putting a package line in both the programs and tried importing it as a package in the third one and it says invalid package name.
Can anybody help.
Thanks in advance.

Importing Class

I was reading the tutorial on importing class's. This is what
I read
Importing classes
To reference a class in another script, you must prefix the
class name with the class's package path. The combination of a
class's name and its package path is the class's fully qualified
class name. If a class resides in a top-level classpath
directory--not in a subdirectory in the classpath directory--then
its fully qualified class name is its class name.
To specify package paths, use dot (.) notation to separate
package directory names. Package paths are hierarchical, where each
dot represents a nested directory. For example, suppose you create
a class named Data that resides in a com/xyzzycorporation/ package
in your classpath. To create an instance of that class, you could
specify the fully qualified class name, as shown in the following
example:
var dataInstance = new com.xyzzycorporation.Data();
My Question is about com/xyzzycorporation/ . would the full
class parth be c:/com/xyzzycorporation/ . Why do they never state
the drive letter when teaching about directories.

Because there is no need. you don't need to reference the
drive letter.
Here's the basic jist of what they are saying....
Single Class File...
If you create your own custom class and want to use it in
your flash file, save it into the same directory as the fla file
and call the classes constructor. By default flash will look inside
the folder where the fla resides in for the class files if it
cannot find it inside the default directory.
Multiple Class Files - 1 Project (often referred to as
packages)
Use your qualified domain name but backwards.....
my domain is www.sd-dezign.com so if I was going to include a
package of utility class files in my document I would do the
following
Create a folder in the same folder with my fla name it com
and inside that a folder called sddezign and inside that utils and
all my as files would be in there...the folder structure might look
like this....
myfile.fla
com
>sddezign
>>utils
>>>box.as
>>>circle.as
To call the constructor for each class, I have two options.
The first which is by far the easiest looks like this
In whatever frame you need to call that class constructor
include "com.sddezign.utils.*";
var myBox:Box = new Box();
The second method requires more typing and can get tedious
var myBox = new com.sddezign.utils.Box();
Hope this helps you a bit better.

To ragnic and other about Singleton class

Hi ragnic. Thanks for your reply. I posted the code wrong. Heres' my correct one.
I have a GUI first loaded information and the information is stored in a databse, I have some EJB classes..and my singleton class ABC has some method to access to the EJB..
so my first GUI will gather info using singleton class and later if I click on
a button in my first GUI class, will pop up another frame of another class , this class also need to class setPassword in my Singleton..
are my followign codes correctly??
iS my Class ABC a SINgleton class? thanks
Is my class ABC use as single correctly. And It is called from other classes is also correct?
I'm new to java and like to learn about Singleton class.
But I really dont' understand it clearly after reading many examples of it.
I have a project to convert my class abc to a singleton.
But I dont know how to do it.
In my class(soon will become a singleton) will have few methods that later I need to use it from another class A and class B.
I have a GUI application that first load my class A..and my class will call
class abc(singleton) to get some information from it.
and then in class A has a button, if I click on that button I will call SIngleton class again to update my password, in the singleton class has method calls updatePassword. But I dont know how to call a singleton from other class.
I have my code for them below:
1)public class ABC //attempt using a singleton
private static ABC theABC = null;
private ABC(){}
public synchronized static ABC getABC()
if(theABC == null)
theABC= new ABC();
return the ABC;

Please help me.thanks

1. When replying, use <reply>, don't post a new topic.
2. Implementing a singleton is a frequently asked question. Search before you post.
3. This is not a question about Swing. A more appropriate forum would be "New To Java Technology" or perhaps "Java Programming", but see point 1.
4. When posting code, keep it short. It increases the chance of readers looking at it. And in composing your shorter version for the forum, you just may solve your problem.

Import Flare Libraries

Flare is an awesome data vizualization toolkit. Flare is a
collection of ActionScript 3 classes for building a wide variety of
interactive visualizations. For example, flare can be used to build
basic charts, complex animations, network diagrams, treemaps, and
more. Flare is written in the ActionScript 3 programming language
and can be used to build visualizations that run on the web in the
Adobe Flash Player. Flare applications can be built using the free
Adobe Flex SDK or Adobe's Flex Builder IDE. Flare is based on
prefuse, a full-featured visualization toolkit written in Java.
Flare is open source software licensed under the terms of the BSD
license, and can be freely used for both commercial and
non-commercial purposes.
Now, I downloaded the
flare-prefuse
visualization toolkit, from the
flare-prefuse.org site.
Following the steps in the
Flare Tutorial,
for the life of me I can't seem to import the flare libraries into
the Tuturial project within Flex Builder.
How do you import projects into another project? I'm able to
import the libraries so that they appear in the Flex Builder's
Navigation pane. I go through the "
Importing a libarary with another project" steps mentioned
below. When I click "OK" to add a project, the project name (eg.
flare.util) does not appear in the Library Path window. Further,
when I use a statement to reference the library, such as import
flare.animate.Tween, the FB2 compiler returns an error, "Definition
flare.animate:Tween could not be found".
Specifically, the flare tutorial states:
Importing Libraries
Before proceeding, make sure you have the flare libraries
loaded as projects within Flex Builder. You should have already
unzipped the flare files into your main Flex Builder workspace
directory. The next step is to import them into the Flex Builder
environment:
- Make sure you are in the "Flex Development" perspective.
- Right click the navigator pane on the left.
- Select "Import..." in the popup menu.
- In the dialog, select "General > Existing Projects into
Workspace" and click the "Next" button.
- Use the "Select root directory" widgets to navigate to your
Flex Builder workspace directory
- You should now seen the flare projects listed in the
"Projects:" panel
- Make sure all flare.* projects are selected and then click
the "Finish" button.
You should now see all the flare projects in the Navigator
pane. You can now browse the source code for each of the
sub-libraries.
Overview of the flare libraries
Here is a quick overview of the various flare projects:
flare.animate: animation library (depends on flare.util)
flare.data: library for loading data sets, useful, but still
under development (depends on flare.util)
flare.demos: an application project showcasing a number of
visualization demos
flare.physics: a physics engine, useful for physical effects
or force-directed layout (no dependencies)
flare.query: a query processor for ActionScript objects
(depends on flare.util)
flare.util: a set of utility classes shared by all projects
(no dependencies)
flare.vis: the flare visualization components and operators
(depends on flare.util, flare.animate, and flare.physics)
If a project has a dependency, you will need to import all
dependent projects into your application. We now describe how to do
that.
Importing a library within another project
Now we need to adjust our project settings so that we can
make use of the flare libraries. Just follow these steps:
1. In the Navigator pane, right click the top folder of the
"Tutorial" project
2. Click "Properties" in the context menu
3. In the resulting dialog, click "ActionScript Build Path"
in the left panel (it should be the 3rd item from the top)
4. Click the "Library path" tab in the right panel
5. Click the "Add Project" button
6. You should now see a list of projects, including all the
flare libraries.
7. Select "flare.util" and then click "OK"
You've now added the flare.util libraries to your project,
and can use any of the classes it provides. Repeat steps 5-7 above
for the "flare.animate", "flare.physics", and "flare.vis" projects.
(We will be using the flare.animate classes in this part of the
tutorial, and then adding in the flare.vis classes in the next
part, so we might as well import them all now). "
My directory structure for the Tutorial project is:
C:\Documents and Settings\Ron Barrett\My Documents\Flex
Builder 2\Tutorial
Can you help to explain to me how to import the flare
libraries so that they are available to the Tutorial project?
Man, if you can help me out with this I'd be REALLY
grateful!!
All the best,
Ron

Hi Magicrebirth:
Jeff Heer, of UC Berkeley, responded to my question, which
was also posted on the SourceForge Flare forum. The following is
his reply, which solved my problem. The easy answer is simply to
download and install FlexBuilder beta version 3.
Sorry for your troubles! The tutorial was written and tested
with Adobe
Flex Builder 3 Beta, so one solution would be to use FB3
instead.
Another approach may instead be to do a clean import of the
projects.
To do this, first delete the following files in each flare
project:
.actionScriptProperties
.flexLibProject
.project
Next, you can manually set up each project. In Flex
Development mode,
right click in the Flex Navigator and select "New
> Flex Library
Project". Now create a new project. Flex Builder
acts strangely when
project names have a "." in them, so leave
the "." out of the name. For
example, type "flareutil" instead of
"flare.util". After typing the
name, click OK. There should now be a project named
"flareutil" in the
navigator pane.
Now rename the project: right-click the project and select
"Rename...".
Now add the "." back into name (for example
"flareutil" should become
"flare.util"). In a warning message pops
up, just dismiss it. The
project should now have the correct name and include the
files in the
flare.util folder.
Now we just need to setup the project settings. Right click
the project
and select "Properties". A dialog window
should appear. In the list on
the left, select "Flex Library Build Path".
Under the tab "Classes",
make sure the box next to the "flare"
package is checked (all sub
checkboxes should be checked as a result) -- this makes sure
all the
files are included with the project.
Finally, you need to set up any project dependencies. These
are
described in the Tutorial. For example, flare.animate has a
dependency
on flare.util. To specify this, click the "Library
path" tab in the
Properties dialog. Now click "Add Project"
and select the project to
add. After you've done that, the project should appear in the
"Build
path libraries:" list. Click the "Link
Type" setting under the newly
added project reference, click the "Edit"
button on the right, and
adjust the link type to "External". Now
repeat this for any other
project dependencies.
Repeat the above process for each of the included flare
projects. The
only difference is for flare.demos. For that project, create
a new
"ActionScript Project", NOT a
"Flex Library Project".
As you can see, this involves a bit of busy work, so
switching to Flex
Builder 3 may be simpler.
hope that helps,
-jeff

Importing classes... HELP!!!

I'm using JBuilder Enterprise Edition...
I open a .java file to edit and recompile to test my edit...
However I keep getting errors that classes imported in the ,java file do not exist...
I know they do, because I copied them locally to the folder where all the filess I need are located...
The .java files that compile into .class files are read-only (there are over 100 of them)
I've pulled them from a server to my local machine...
Even if I check them out in Visual Source Safe, I still get errors that the imported classes in the source code do not exist...
how do I fix this issue?

Looks like I had a copy of JBuilder installed after all. So I selected Project-> Project Properties select the Paths tab then the Required Libraries tab (lower tab), hit the add button, then hit the new button. Fill in the library name and select project to hold the library. Then search your disk for the jar or the directory that contains your classes. Then hit OK a few times.

Error when I import classes using directive JSP page

Hi all!
I have installed JDeveloper 11g (11.1.1.3.0)
My applications are located in the C:\dir (JDEV_USER_DIR = C:\dir)
I Created application "Appliation1". In it i created 2 projects (Project1, in it beans session entity and other java classes; Project2, in it JSP).
I want import classes from Project1 to Project2 using next directive:
<%@ page contentType="text/html;charset=windows-1252"
import="project1.*"%>
so in Project properties of Project2 set the way to classes in Project1.
When i run JSP an error occurred:
Error(4,9): The import project1 cannot be resolved
Maybe i'm not set correctly the way to the classes
Thanks in advance.

angelr, thanks, it helped me)
In jdeveloper 10g i set address in Project Properties->Libraries and Classpath->Add JAR/Directory;
and set the way to my classes;
and it worked.
in the 11 version seems different

Doesn't find import classes...

Hi Wei,
          I removed everything that was related to JVIEW in the script and it's the
          same thing :(... can you explaine one thing to me?
          My GenerateHTML bean is compiled and if I don't import anything in it, it
          works fine and I can call methods of it... no problem. But when I import
          some libraries (jar files) in my, it compiles fine but when I want to use it
          in my jsp page it can't find the import packages... why? It's already
          compiled and those packages are in my system classpath... it even works if I
          open a prompt and do it at the commandline!
          Is there a rule to follow when using a bean in jsp that applies to importing
          packages in that bean?
          Thanks !

Import classes or packages

import java.util.*;
import java.util.ArrayList,java.uitl.HashMap;
What difference it makes to the performance of a class
file when we import a specific class or an entire package

For a great Q & A on this very question:
http://www.javaworld.com/javaworld/javaqa/2001-04/01-qa-0406-import.html?
Here is the quoted information:
"Q. Does importing an entire package cause any runtime or compile time overhead? For example, does:
import java.util.*
compared with:
import java.util.Vector
cause any added overhead?
A. In answering your questions a few definitions are helpful:
Imports of the type java.util.Vector; are referred to as single type import
Imports of the form java.util.*; are referred to as import on demand
Both import on demand and single type import are passive mechanisms. As passive mechanisms, import loads information about the package and types only when it is needed. Indeed, the compiler will load this information only when a type is actually used, not when it is simply imported. The import simply tells the compiler where to look when it actually needs a type.
So no, importing an entire package produces no more overhead than importing a specific type.
That being said, it is generally regarded as bad practice to import an entire package using import on demand. Sometimes the number of imports may be large. However, you can quickly look at the list and know what classes the importing class uses. Such a list of imports can provide important documentation to someone unfamiliar with the code. "

Class Libraries and Code used to Access Google Distance Matrix API

Hey Everyone....! I want to use Google Distance Matrix API with my C# application, which gets two co-ordinates(Latitude/Longitude) and pass them to API. Also to receive the results from API and construct and output class to interpret JSON objects.
Can anyone please tell me about class libraries and code used for above purpose.

Not allowed to import classes without package names?

Hi,
I have a few questions on Packages and importing?
1. Is the following true that it is illegal to import classes in the same package as the current class, will this cause a comilation error? If this is the case where in the Java Language specification is this actually written as I could not find it?
2. This has probably been answered by question 1 but if I have 2 classes in the same package and if I import 1 of the classes into the other class, is it illegal to import it by just using the class name and not the package name as well, ie
if the package name is ie.tcd
and the 2 class names are exp1.class and exp2.class, can I do this in class 2
package ie.tcd;
import exp1;
public class exp2 {
3. Is it illegal to import classes that are not explicitly part of any package or must a class be part of a package to be imported. I read somewhere that while this was always illegal it is only after jdk 1.4.2 that this is being enforced? If this is the case where in the Java Language specification is this actually written as I could not find it either?
Thanks very much for any help,
John

Was just also wondering, 1 other thing, I am looking
at someone elses code they have 2 classes (Class A
and Class B) in the same package (pkg). The person
imports class A into B:
package pkg;
import A;
public class B {
Is this legal code (or was it ever)?Not if A is really in pkg.A. If there is an A in the unnamed package it was legal, or at least it was understood by the compiler, and now it isn't (to both).
Can you import or is there a point in importing a class in the same
package?Only by naming the package in the import statement. If the current and the import statement are in the same package the import is redundant.
If there is a point would you import just be
using the class name (this would be illegal after jdk
1.4) or should you use the whole package name even
though it is in the package anyways?As I understand it you must always use the whole package name in imports.

Compilation Error for import classes not found in generated Proxy Class

Hi,
We are generating java classes for the COM dll using JCOM com2java compiler.
We are getting a compilation error for import class not found when compiling the
generated Proxy java source code. It can't find the com.bea.jcom.Dispatch class that
the generated Proxy java source code extends. It also can't find com.bea.jcom.Variant
or com.bea.jcom.Param. These are interfaces or data types or classes used by COM
library.
I added weblogic.jar to my class path and the only Dispatch class i found inside
the weblogic.jar is com.linar.jintegra.Dispatch;
We have com objects for which we want to develop an EJB client to interface with
the COM object using JCOM with Native Mode disabled.
Any help on the compilation error..I tried changing the extends for Dispatch to com.linar.jintegra.Dispatch
but the other errors are still there.
To begin with, I think the generated code should not refer to any of the COM data
types.
Any help please.
Thank you in advance,
Regards,
Rahul Srivastava

Hi,
I resolved the other errors by changing all references from com.bea.jcom.Variant
etc to com.linar.jintegra.class name..all were present under the com.linar.jintegra
package.
Thank you all anyways,

To begin with, I think the generated code should not refer to any of the
COM data
types.
Any help please.
Thank you in advance,

Inner class vs. imported class

Hi everyone,
I have entitiy beans created for a client's web app I'd like to use in the
web service using WebLogic Workshop 7.0. Say the classes are imported like
this in the services:
import com.hoike.clientname.ap.bean.Invoice
import com.hoike.clientname.ap.bean.Vendor
Instances of these classes are used in callback methods and some of the
service methods.
When I generate the CTRL file, it actually adds those imported classes as
inner class of the service defined.
The problem is that when I try to used these services from another service,
I cannot use the imported classes (as Invoice or Vendor), but instead I have
to use the inner class (InvoiceService.Invoice or VendorService.Vendor)
Does WebLogic Workshop 7.0 only allow you to use inner classes? Is there a
way to use custom classes as method parameters?
Thanks in advance!
Makoto

how do you declare your inner class?
Is it (public)
public static class MyInnerClassor (private)
private static class MyInnerClassor (package)
static class MyInnerClassor (protected)
protected static class MyInnerClassTry to change the way you declare the inner class. Use protected or package or public instead.

About importing class libraries?
