How to use java api while java programming especially using javase and java swing?

i need help for java api for undo, redo, htmleditorkit,editorkit.
in my project i have to use java swing for desktop application but, i need help for how to implement and how to retrieve java api.
please reply with example or code..
You find examples and code by searching the internet, not by using forums.
Start with The Java Tutorials - it has trails for the bulk of the Java functionality.
See the trail 'How to Write an Undoable Edit Listener'
http://docs.oracle.com/javase/tutorial/uiswing/events/undoableeditlistener.html
You learn by DOING - not by reading. Actually DO the tutorial example and try to understand WHAT it does and HOW it does it.
Then search for other tutorial trails that are of interest.

Java API from ABAP program.

Hi
I have a requirement to call a Java API from ABAP program.
We are using a third party component for encrypting the files
using Java API The component consist of ".jar" files. I need to
know exactly where we need to copy the ".jar" files on application server,
so that I can call the API methods in my ABAP code and process the file in SAP,
and how to establish a connect with there server for the encryption.
Thanks

IAS
IAS is Oracle's next evolution of the web server and application server
product technology superceeding the Web Application Server (WAS) and Oracle
Application Server (OAS) product lines.
IAS SERVLET API JSP API EJB API EJE VERSION
VERSION VERSION VERSION VERSION SUPPORTED
9I(1.0.2) 2.2 1.1 1.1 817
8i(1.0.1-NT) 2.0 1.0 1.0 816
8i(1.0.0-UNIX) 2.0 1.0 1.0 816
The IAS product contains two Java Virtual Machines (JVM) within it's
architecture.
They are called :
1) APACHE JSERV servlet engine
2) ORACLE ENTERPRISE JAVA ENGINE (EJE)
APACHE JSERV servlet engine
The APACHE JSERV servlet engine is an EXISTING product licensed from the
apache group which supports the servlet api 2.0.ONLY.
The APACHE JSERV product does not support ANY JSP's unless the customer
installs a third party jsp engine.
The IAS 8i/9i which has the APACHE JSERV product embedded in it, comes with
Oracle's JSP engine (OJSP) already integrated into it. OJSP supports JSP's up
to the specific JSP engine version documented in the Oracle Universal
Installer (OUI) for the 8.1.7 RDBMS or the IAS products. It is also documented
in the product's release notes.
Oracle ENTERPRISE JAVA ENGINE (EJE)
The EJE formerly known as :
1) Oracle 8i Java Virtual Machine (JVM)
2) JSERVER component,
3) Aurora JVM
was originally releas ed in the RDBMS 8.1.5 database with jdk 1.1.6 based java
support.
The currently supported versions of the Oracle 8i RDBMS, versions 2 and 3,
also known as Version 8.1.6 and 8.1.7, respectively, provides a jdk 1.2.1
based java virtual machine support.
"EJE" Version 816
This EJE, found in rdbms 8.1.6 and IAS 8i, contains support for the ejb
api 1.0, corba, and java stored procedures.
"EJE" Version 817
This EJE, found in rdbms 8.1.7 and IAS 9i, contains support for the ejb,
corba, and java stored procedures as well as the Oracle Servlet Engine (OSE)
which provides support for the servlets 2.2 api and JSP 1.1 api.
Note :
EJB support in the "EJE" Version 817 has been upgraded to comply with the EJB
1.1 api specification which includes "entity beans" support.
What is the bottom line ??
1) Servlets deployed to the APACHE JSERV must comply with servlet api 2.0.
2) Servlets 2.1 or higher are only supported in EJE's OSE component found in
the rdbms 817 or ias 9i products. Servlets api 2.0 can also run in the OSE.

which jvm is used by jserv ?? EJE or a separate jdk ?
The Jserv servlet engine is running in a separate jdk JVM external to the EJE jvm which is embedded within the "database" component of ias and the RDBMS.
See the reference below for more details ...
if jserv only support old apis, why it is in oracle's products ?
i would assume that the oracle servlet engine was under development when ias 8i was released and became available in time for the ias 9i and rdbms 817 products.
looking back in history leads me to believe ias 8i was a migration path to get to ias 9i or rdbms 817.
Based upon the long history of new releases of every oracle product being upgraded with new features, it's reasonable to assume that these products will continue to evolve.
when I deploy a jsp how to deploy in the right servlet container ("EJE") ?
as documented in the reference below, you can deploy JSP's to either the apache jserv jvm or the EJE since the ORACLE JSP engine functionality is in both jvm's.
there are many posts where you can see that people have deploy in jserv and they have problems because they don't use the right container (servlet 2.0 instead of
servlet 2.2) http://technet.oracle.com:89/ubb/Forum2/HTML/006349.html
when ias 8i came out this was clearly an issue since servlet support was at api 2.0, and the current servlet api was probably at 2.1.
oracle clearly made every effort to get ias 9i released quickly to supply a servlet 2.1 and 2.2 capable engine to resolve this issue.
since ias 9i and rdbms 8.1.7 are available this is no longer an issue.
The reference below explains the architecture and understanding it would eliminate a lot of "deploy to the wrong ias 9i component" issues.
so why jserv is bundled with oracle 8i/9ias since EJE support the right api version ?
if in ias 9i release , oracle had removed the jserv component without any advance warning, many customers would have been very upset since oracle makes every attempt to give advance notice before removal of functionality.

How to import WMV file for use in adobe programs, especially After Effects and/or Premier?

How to import WMV file for use in adobe programs, especially After Effects and/or Premier?

I have the latest adobe creative cloud and i'm using Mac 10.8.2
My client gave me a wmv file that she wants some people blurred out in the background but when I go to import the media, it's greyed out. I'm assuming that After Effects will be the best solution for this, but maybe there is another way.
I can purchase a video converter and convert it to .mov but that costs extra money that I don't want to spend just to do this one project.

looks like the gtk theme is not the problem. didnt really think it was, but the documentation was worth posting. the guys over at ubuntu look as though they have dealt with this in great detail, and have produced a few solutions, which may or may not work. i have decided to post these for anyone else who may have these problems.
Solution 1 - new user creation:
https://bugs.launchpad.net/ubuntu/+bug/104521
Solution 2 - config file delete:
http://ge.ubuntuforums.com/showthread.php?t=724439
post number 6 here features the config file delete solution, as well as a link to another post which may be useful.
judging by a google search on this problem and the number of responses that came up, the bonobo/daemon error is quite a common curse for the users of gnome, although much more common in distros such as ubuntu or fedora.
i hope that this proves useful and if anyone has anything to add, please feel free. the more documentation the better.
EDIT:
another solution would be to remove gnome and reinstall it from scratch. (some please tell me if i am doing this correctly. thanks )
1. clean your catch:
pacman -Scc
2. remove gnome, gnome extras, and whatever other gnome files you might have installed
pacman -Rscn gnome gnome-extra etc...
3. reinstall gnome and gnome extras
pacman -Sy gnome gnome-extra
4. reconfigure your desktop the way you want.

How do I restart forcefully while one program I've downloaded online (PDFpen) can't be closed neither removed?!!

Hold down the power button until the screen goes black if it's really necessary.
In your case, you can force quit.
When an app won't quit as it should, click Force Quit from your Apple  drop down menu or press Option + Command + Esc.
Select the app then click Force Quit.
That way it's not necessary to shut down your Mac.

Importing the Java API into basic programs

How do I import the API that comes with the JDK1.3 into my programs ? Is it a case of simply import java.api.*; ??
Does the new 1.3 version of the compiler include a Javabook which can be imported into programs. I have a text book which has sample programs which import Javabook. When I come to compile them, the compiler reports that Javabook is not known. Is Javabook from an earler version of the java compiler ?

It depends on what you want to do just as an example if you wanted to create a window app with a textfield you would need to import the necessary classes. Here is a sample of a JFrame with a text field:
import javax.swing.*;
import java.awt.*;
public class Frame1 extends JFrame
BorderLayout borderLayout1 = new BorderLayout();
JPanel jPanel1 = new JPanel();
JTextField jTextField1 = new JTextField();
public Frame1()
super();
try
jbInit();
catch (Exception e)
e.printStackTrace();
private void jbInit() throws Exception
this.getContentPane().setLayout(borderLayout1);
this.setSize(new Dimension(400, 300));
jTextField1.setText("jTextField1");
this.getContentPane().add(jPanel1, BorderLayout.CENTER);
jPanel1.add(jTextField1, null);
Note the import statements of java.awt.*; and javax.swing.*; this tells the compiler the to look for all the files needed to create this frame. The compiler already knows what it needs from the API, you just have to tell it where to look.
In short JavaBook should either come with the book on CD ROM or you have to download it from the publisher. Also check and see what files you need to import and use the import statement to point to the file that it needs: for example
import JavaBook.*;
Hope this helps

How can I do to share the array elements between "C" and "Java"

Hi,all
I want to implement the function about this: c and java between JNI can share the same data area. For example, when change the value of the array in java, i can get the same value in c.
I use the function:Xxx* GetXxxArrayElements(JNIEnv env, jarray array, jboolean isCopy)
But i find that the "isCopy" is JNI_TRUE which means that i get the pointer which point to a copy,so i can't get the change
in Java later.
How can I do?Can i set "isCopy" with JNI_FALSE??
Thank u.

No, you can't. isCopy is of type jboolean*, and the value is just set by the call to inform you whether the data was copied or not, but you cannot infulence that.
In fact, the VM might store an array of primitives in a different way as C, and this routine has to convert between the two representations. In this case copying is always required.

Java API, problem with secondary keys using multi key creator

Hi,
I'm developing an application that inserts a few 100k or so records into a Queue DB, then access them using one of four Hash SecondaryDatabases. Three of these secondary dbs use a SecondaryMultiKeyCreator to generate the keys, and one uses a SecondaryKeyCreator. As a test, I'm trying to iterate through each secondary key. When trying to iterate through the keys of any of the secondary databases that use a SecondaryMultiKeyCreator, I have problems. I'm attempting to iterate through the keys by:
1: creating a StoredMap of the SecondaryDatabase
2: getting a StoredKeySet from said map
3: getting a StoredIterator on said StoredKeySet
4: iterate
The first call to StoredIterator.next() fails at my key binding (TupleBinding) because it is only receiving 2 bytes of data for the key, when it should be getting more, so an Exception is thrown. I suspected a problem with my SecondaryMultiKeyCreator, so I added some debug code to check the size of the DatabaseEntries it creates immediately before adding them to the results key Set. It checks out right. I also checked my key binding like so:
1: use binding to convert the key object to a DatabaseEntry
2: use binding to convert the created DatabaseEntry back to a key object
3: check to see if the old object contains the same data as the new one
Everything checked out ok.
What it boils down to is this: my key creator is adding DatabaseEntries of the correct size to the results set, but when the keys are being read back later on, my key binding is only receiving 2 bytes of data. For the one SecondaryDatabase that doesn't use a SecondaryMultiKeyCreator, but just a SecondaryKeyCreator, there are no issues and I am able to iterate through its secondary keys as expected.
EDIT: New discovery: if I only add ONE DatabaseEntry to the results set in my SecondaryMultiKeyCreator, I am able to iterate through the keys as I would like to.
Any ideas or suggestions?
Thank you for your attention,
-Justin

Hi Justin,
Sorry about the delayed response here. I have created a patch that resolves the problem.
If you apply the patch to your 4.6.21 source tree, and then rebuild Berkeley DB, the improper behavior should be resolved.

I have the latest version of Java, but on one program I use no longer works, and this was after a Java upgrade. I've tried everything Java suggested but that didn't correct the problem This does no happen when using Internet Explorer

I'm using Windows 7, 64-bit version. The problem did not show up until a few weeks ago. I've also tried all the things that Firefox suggested to do, but no change.

I am creating an VB 2010 Form that will collect data and then automate sharing to select individuals. Right now I am storing the data in the Google Drive folder on the Desktop but some people that may be using this application may not have Google Drive downloaded
on their desktop so I would like to know if there is another way to add the data files (Excel files) to Google Drive. I would also like to have my application automatically share the files with select individuals and possibly publish onto Google+ or at
least create a notification on Google+ that a new file has been added to the Drive. Thanks in advance for ANY help that anyone can offer!

Hello,
Thank you for your post.
I am afraid that the issue is out of support range of VS General Question forum which mainly discusses
the usage of Visual Studio IDE such as WPF & SL designer, Visual Studio Guidance Automation Toolkit, Developer Documentation and Help System
and Visual Studio Editor.
Because you use Google Drive and Google API which are third-party, I suggest consult on its support forum/community provided by its publisher.
IN addition, about Visual Basic programming, please consult on Visual Basic forum:
http://social.msdn.microsoft.com/Forums/vstudio/en-US/home?forum=vbgeneral for better response.
Best regards,
