How to find classes in the package if package path

in java i want to find classes,Interface,Exception names which are presant
in the package..
for example
java.sql; if i give this it should return
class name
Date
Time
DrivarManager
pls helpme in this field

download the jdk documentation or view it here
http://java.sun.com/j2se/1.3/docs/api/index.html
The exact problem is i hava set the path to my application that path contains several jar's(contains classes,Interfaces) and classes with package structure,
now my need is if i run the application ,the application
should find out the classes and Interfaces for given package structure which are present in classpath...
for this i have to load all the classes to memory(using classes loader) . then find out the classes which are present in memory...
or
any other inbuilt method is there in java when i give path structure it find and give classes which are in class path..
for ex..
if i set path to jdk
then if i give the path like java.lang
it should give me the out put as
String (or) String.class
Double
Cloneable
(classes & interface in that package)

How to find (classes,interface,subpackage info) in some package

Plz tell me if any one know how to find (classes,interface,subpackage) in some package
e.g. in java.io
"Above senerio in not concern with java doc
but tell me if an other way i.e by help of programming
i could find some package information"
as we know we find out any "object" classType , methods and fields information with help of "java.lang.reflect" API's
but how to find a package information as provided by jdk is in current use

You can locate the .zip or .jar file where the stuff is, and say either
unzip -l classes.zip
or
jar tvf classes.jar.
So you see the list of the classes in the given package.
Then you can say
javap -classpath classes.zip MyPackage.MyClass
to see the fields and methods of the given class.

Missing classes from the javax.swing package?

Can anyone throw any light on what appears to be a missing class from the javax.swing package?
When CelsiusConverter.java from The Swing Tutorial (code fragment shown below) is compiled the JFrame class can't be found.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class CelsiusConverter implements ActionListener {
JFrame converterFrame;Despite the package javax.swing being imported, the compiler does not seem to be be able to find the JFrame class.
CelsiusConverter.java:14: Class JFrame not found in type declaration.
JFrame converterFrame;To attempt to solve this issue all the files in jdk1.5.0_02\lib were added to CLASSPATH.
CLASSPATH was set to C:\Program Files\Java\jdk1.5.0_02\lib\dt.jar;C:\Program Files\Java\jdk1.5.0_02\lib\htmlconverter.jar;C:\Program Files\Java\jdk1.5.0_02\lib\jconsole.jar;C:\Program Files\Java\jdk1.5.0_02\lib\tools.jar;C:\Program Files\Java\jdk1.5.0_02\lib;C:\Program Files\Java\jdk1.5.0_02\lib\ir.idl;C:\Program Files\Java\jdk1.5.0_02\lib\jawt.lib;C:\Program Files\Java\jdk1.5.0_02\lib\jvm.lib;C:\Program Files\Java\jdk1.5.0_02\lib\orb.idl;C:\Program Files\Java\jdk1.5.0_02\demo\jfc\SwingApplet\SwingApplet.jar;.;c:\CoreJavaBook

This is extremely strange... If you're sure it's not a problem in your code or with your classpath, the only other thing I can think to suggest is re-downloading / installing java

When I open iPhoto 9.2.1 it says that my library needs to be upgraded but when I upgrade the library I am trying to open (33 GB worth of pictures from 2006) the new application says it cannot read the files and how to find them on the system to reimport?!

Why is upgrading software iPhoto such a pain. I've gotta get a presentation done and all I get for my money is roadblock!!!

hello, it sounds like the library is damaged.
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

How to find out about the SMTP Server

Hi,
I have been trying to configure groupware in the portal - in particular I want to enable the sending of emails through the portal. I already have a how-to-guide that that seems to explain the steps quite well. However, it mentions that I need to know the SMTP Server of the email. Can you tell me how to find out about the SMTP Server? Where do I need to look for the name of it?
Thank you and regards,
Katharina

Hi Katharina,
you need the SMTP server of your company. This means you can't look for it in the portal, but have to ask the responsible person in your company.
Kind regards,
dominik

I have an app on my iPhone that I want to download on my iPad . Red icon with Chinese writing. Because I do not speak Chinese I do not know how to find it. The application is photography by different individuals of their vacations/trips. Can someone help

On your iPad go to the App Store icon, Tap on the Purchased Tab.
It will show you all the Apps that have been bought with the Apple Id currently in use by the iPad.
Assuming its the same one being used on the iPhone, you should be able to find the App there.
To further help you find it you can tap on the "Not on this iPad" button to limit the results to just Apps not currenlty installed on your iPad.

How to find classes in a particular package?

Does anyone know how in Java to find out what classes belong to a particular package? Or to find out what classes inherit from a particular class?
The reason why I'm asking this is that I want to create a BeanInfo property editor for a widget that will give me a list of any classes in a particular package. I know what that package can be and I know what the main class is that everyone should inherit from. I can easily create a beaninfo property editor with a string array of the classes, but I don't want to have to go back and maintain this code everytime I add another class to that package. I would love to use introspection but I haven't found the right commands to use yet.
Anyone have any ideas?
Thanks!

Not too difficult, the following snippet is used to gather information about a class. beanClass can be parsed to extract package name. and you ask the class directly about its superClasses and implemented Interfaces.
    private Class beanClass = null;
    private Class beanSuperClass = null;
    private Constructor[] constructors = null;
    private Field[] fields = null;
    private Method[] methods = null;
    private Object beanInstance = null;
    public setBeanDetail(Object o) {
        beanInstance = o;
        beanClass = o.getClass();
        beanSuperClass = beanClass.getSuperclass();
        constructors = beanClass.getConstructors();
        fields = beanClass.getDeclaredFields();
        methods = beanClass.getMethods();
    }have loads of fun with it.

How to find classes in a java package

i am writing a java IDE. i want to extract all class names from a java package eg. java.lang (through coding). how can i do that.
Thanks in advance

File file = new File("path to your jar file");
JarFile jf = new JarFile(file);
Enumeration e = jf.entries();
ZipEntry ze = null;
while(e.hasMoreElements()){
ze = (ZipEntry) e.nextElement();
ze.toString(); // gives you the file name
you have to understand java.util.jar java.util.zip packages for working with jar/zip files.
Hope this helps

How do I get class in the javax.* package

How do I get class in the javax.* package

If possible don't mess with the javax Package
I mean I could not get the advantage of getting a class under javax Package
But for information
make a folder named javax
Make your class in that folder with starting code as
package javax;and then compile it and make a jar file and add it to classpath
It is very simple
But I think you should not mess with it
Is there any special requirement?
Bye for now
