How can I use JEditorPane in my simplified web system? URJENT!!!!!

Hello friends!
In my client side browser..I would like to display the contents of web pages which are retrieved from the web server.
Does the JEditorpane is useful in this scenario? if so how can i display?
As i accept data in stream from the server..how can i give it to JEditorpane?
Please do reply me ...fastly.

If you want something done fast, then why don't you try reading the API. The API:
a) points your to the Swing tutoral on "Using Text Components" which has a working example
b) shows you 3 ways to load data into the JEditorPane.

How can WLS use JSP pages in a Web Application witth just a JRE [Web Application, WAR, JSP, weblogic.jsp.pageCheckSeconds and JRE]

 How can WLS use JSP pages in a Web Application (either a .war file or a war directory structure) without a java compiler?
 I suspect either the JSP specification is flawed (i.e. it doesn't take account of servers using just a JRE), or BEA's implementation is broken.
 Production servers do not have a JDK installed. They only have a JRE. Therfore a java compiler is not present on the machine that the Web Application is deployed onto.
 On the development machine, when the server is requested to load the JSP it creates a tmpwar directory within the Web Application directory structure. This is then included in the resultant .war file thus:
 D:\war>jar -tf gmi.war
 META-INF/
 META-INF/MANIFEST.MF
 gmiService.jsp
 WEB-INF/
 WEB-INF/classes/
 WEB-INF/classes/com/
 WEB-INF/classes/com/bt/
 WEB-INF/classes/com/bt/gmi/
 WEB-INF/classes/com/bt/gmi/gmiService.class
 WEB-INF/getList.xsl
 WEB-INF/getListByConnection.xsl
 WEB-INF/getListByDistrict.xsl
 WEB-INF/getListByDistrictConnection.xsl
 WEB-INF/lib/
 WEB-INF/source/
 WEB-INF/source/build.bat
 WEB-INF/source/gmiService.java
 WEB-INF/web.xml
 WEB-INF/weblogic.xml
 tmpwar/
 tmpwar/jsp_servlet/
 tmpwar/jsp_servlet/_gmiservice.class
 tmpwar/jsp_servlet/_gmiservice.java
 When deployed on the production server with the web.xml file set to use the following values (note XML stripped):
 weblogic.jsp.pageCheckSeconds
 -1
 weblogic.jsp.precompile
 false
 weblogic.jsp.compileCommand
 javac
 weblogic.jsp.verbose
 true
 weblogic.jsp.packagePrefix
 jsp_servlet
 weblogic.jsp.keepgenerated
 false
 And in the weblogic.properties file:
 weblogic.httpd.webApp.gmi=war/gmi
 I've also tried with the .war file, but that insists on creating another tmpwar directory outside of the .war file.
 Then, although I have set pageCheckSeconds to -1 (don't check and don't recompile) ter production server still attempts to recompile the JSP's:

The default Java compiler from sun lives in the tools.jar that comes with
 the JDK. Just add that to your set of JARs which are deployed in production
 and you should be fine. No need to install the full JDK - just make the
 tools.jar available to WebLogic.

How can I use a SWF as a web request proxy between Javascript and my server?

I know I can call my server directly from javascript. However, I want to do this through a non-GUI SWF file.
I'm fairly new to Flash but have gotten all the CS3 tools from work.
Does anyone know of any examples on:
1. how to make a web request from within flash provided the URL, post content, and timeout
2. how to call a Flash API from javascript asynchronously
3. how to detect whether the browser being used can support my SWF (I don't want it to prompt to install Flash if they don't have it yet)
I'm actually hoping someone has already done this and has a sample already built.
Thanks for any help.
Kevin

glkad - I think you misunderstood what I'm after.
I don't just want to send the browser to another URL. Here's the flow:
A. javascript initiates a GET or POST web request through the SWF file providing a timeout
B. the SWF actually makes the request to the server failing if the timeout is exceeded
C. the SWF notifies the javascript when the call is complete (or times out) and provides the content returned from the server as a string
I'm looking for more details regarding your answer #3. HOW can Idetect if flash is available? (remember, I'm a newbie at flash )
Thanks.

How can i use the gui of the operating system

hi
i am working with the gui and i want to ask how can the gui of the java be like the operating system..
ex : i want the buttons and the frame be like the windows xp .. not appear as default..

i read the UIManager and i found more methods that getting the font the dimension but i want that when i drag and drop the code already inherent the gui (the shape of the buttons , frame and tool bar from the operating system)
ex : i working with windows xp, i want the shape of the gui of the frame that i drag and drop it be like the gui of xp)

I'm currently using Linux Fedora system.
Doesn't matter. There's no standard way for D&D on Linux, no single API.
Every application has its own mechanism which may or may not be compatible with any other.
Gnome and KDE groups are doing some work to provide a common standard but as you know the Linux zealots are completely opposed to anyone telling them what to do (such as creating standards) and won't in general follow them.

How can one use the physical memory of our system rather than virtual memory while running Labview?

We have a Windows NT system with 2 Gb of physical memory and would like to utilize the RAM fully using Labview. What usually occurs is that Labview uses a tremendous amount of page file space while a majority of the physical memory is unused. Is there a way to configure Labview (or our system) to overcome this problem? It seems that our processes would be much faster if they were mainly using the physical memory. Is it possible to trick the system, by creating a RAM disk and allocating this as virtual memory space?

LabVIEW the application doesn't know anything about physical versus
virtual memory. LV asks the OS for general purpose memory and goes
from there.
Drivers like DAQ and IMAQ will have a combination of general user
memory and page lo
cked physical buffers.
I'm not up on the details, but this is something that the OS is in
control of, so that is where you need to look for the solution. One
of the things to look at is the disk cache. By default, I think that
NT takes a percentage of the RAM to use for disk cache. With that
much RAM, this is probably unnecessary and is using too much.
Similarly, the OS may be attempting to keep the working set size
to a fraction of the total RAM to reserve space for other things.
It doesn't make sense to me, but then I don't work for MS.

How can I use File DSN to connect to database?

Hi,
I am using ODBC-jdbc driver to connect to the database. It seems that the DSN name is required. How can I use a file DSN instead of system DSN to connect to database? Please help?

oracle provided jdbc drivers (thin and oci) do not use odbc.
why would you want to slow things down by sending "round trip" data transfers thru a "jdbc to odbc" and thru "odbc to jdbc" conversion routines.
It isn't necessary with the oracle provided drivers !!

How can i use param in my select query ( see code)

Hi ,
I need to use the param instead of hardcoding the value in the select query , when i did that it is working .
I think the limit of args is only till the end of main and my select query is in a method called Load() .
How can i use the param in my select query .
public static void main(String[] args){
name = args[0];
class= args[1];
new Load();
}//end of main
public Load()
          try {
               Class.forName(JDBC_DRIVER);
               connection = DriverManager.getConnection(DATABASE_URL,"username","pw");
               statement = connection.createStatement();
               //First Query : pin and ticket number
               ResultSet resultSet = statement.executeQuery("SELECT pin , ticketnumber from airport ,year where "+                                                                     "year.year_name= Here i need to use the param (instead of hardcoding) and year.class_year= Here too i need to use param");
}// end of method Load()Edited by: 1sai on Sep 24, 2008 7:34 AM

Might I suggest you change the structure of your program to the following:
public class Load {
private Connection conn;
private PreparedStatement statement;
public Load(String sql) {
    init(sql);
protected void init(String sql) throws Exception {
    Class.forName(JDBC_DRIVER);
    conn = DriverManager.getConnection(DATABASE_URL, "username", "pw");
    statement = conn.prepareStatement(sql);
public ResultSet execute(String p1, String p2) throws Exception {
    statement.setString(1, p1);
    statement.setString(2, p2);
    return statement.executeQuery();
public void close() throws Exception {
    if (statement != null)
      statement.close();
    statement = null;
    if (conn != null)
      conn.close();
    conn = null;
public static void main(String[] args) throws Exception {
    String sql = args[0];
    String param1 = args[1];
    String param2 = args[2];
    Load load = new Load(sql);
    ResultSet rs = load.execute(param1, param2);
    while (rs.next())
      System.out.println(rs.get(0));
    rs.close();
    load.close();
}This allows you to use the same "Load" object for multiple queries with different parameters.
I do not recommend you actually use the code above in any sort of production application. You should really take a look at Spring Framework along with an ORM tool like Hibernate or Ibatis to simplify your DAO layer.
Hope this helps,

How can I use 2 Apple IDs in Itunes? I have 2 IOS Devices. They each have there own AppleID. What is the proper way to sync both of them to Itunes?

How can I use 2 Apple IDs in Itunes? I have 2 IOS Devices. They each have there own AppleID. What is the proper way to sync both of them to Itunes? I wanted my teenager's AppleID to be different from mine so that she couldn't charge stuff to my AppleID, therefore I created me another one. Now when I go to Sync either device, it tells me that this IOS device can only be synced with one AppleID. Then I get a message to erase it, not going to do that, lol. If I logout as one ID and login as the other, will it still retain all synced information on the PC from the first IOS device? If I can just log in out of the AppleID, then I have no problem doing that as long as the synced apps, music, etc stays there for both. I am not trying to copy from one to the other, just want to make sure I have a backup for the UhOh times. If logging in and out on the same PC of multiple AppleIDs is acceptible then I need to be able to authorize the PC for both devices. Thanks for the help. I am new to the iOS world.

"Method Three
Create a separate iTunes library for each device. Note:It is important that you make a new iTunes Library file. Do not justmake a copy of your existing iTunes Library file. If iTunes is open,quit it.
This one may work. I searched and searched on the website for something like this, I guess I just didn't search correctly, lol. I will give this a try later. My daughter is not be back for a few weekends, therefore I will have to try the Method 3 when she comes back for the weekend again. "
I forgot to mention that she has a PC at her house that she also syncs to. Would this cause a problem. I am already getting that pop up saying that the iPod is synced to another library (even though she is signed in with her Apple ID to iTunes) and gives the pop up to Cancel, Erase & Sync, or Transfer Purchases. My question arose because she clicked on "Erase & Sync" by mistake when she plugged the iPod to her PC the first time. When the iPod was purchased and setup, it was synced to my PC first. When she went home, she hooked it up to her PC and then she erased it by accident. I was able to restore all the missing stuff yesterday using my PC. However, even after doing that it still told me the next time I hooked it up last night that the iPod was currently synced with a different library. Hopefully, you can help me understand all this. She wants to sync her iPod and also backup her iPod at both places. Both PCs have been authorised. Thanks

How can i use my account without the billing info, as i do not have a credit card. and my shipping and billing info is under US. i'm in singapore. how do i change this?

how can i use my account without the billing info, as i do not have a credit card. and my shipping and billing info is under US. i'm in singapore. how do i change this?

If you are just visiting Singapore, then leave the account as it is. If you have moved there, then view your account using the iTunes app on a Mac or PC and change the country/region to your current location and address. If you do not have a bank card, you can fund your account using iTunes gift cards if available in Singapore.

How can i use microsoft word on ipad 2

how can i use the microsoft application on my ipad 2?

The Pages app is also compatible with MS Word. Unlike some of the others mentioned, the document is actually stored on the iPad as opposed to 'the clouds'. Again, most of those mentioned are cut down versions of MS Word.
Stand back and look at this constructively; do you need to regularly access to the document from more than one computer/device without the need to keep amending your document on your computer and sending it to your iPad? If so, Documente to Go etc may be the best choice.

How can I use the credit on my account instead of credit card to buy apps?

I have a gift card credit on my account but when I want to buy an app it takes me to my credit card details. How can I use my credit on my account instead of credit card?

You shouldn't have to put in a credit card, no, but from time to time the iTunes Store seems for some reason to try to insist on one. If just confirming your mailing address doesn't stop it from complaining, go here:
http://www.apple.com/support/itunes/contact/
and follow the instructions to report the issue to the iTunes Store.

How can i use one SQL statement to solve problem?

How can i use one SQL statement to solve the question below?
For a Table named A, there is a column named F(char type).
Now select all the records where F like '%00' and update their F value to '%01'
Just one SQL statement.Do not use PL/SQL block.
How to do that?
Thanks.

What is the data volume for this table?
Do you expect lots of rows to have '%00' as their value?
Following two statements come to mind. Other experts would be able to provide better alternatives:
If you have index on SUBSTR(f, 2):
UPDATE A
SET    f = SUBSTR(f,
                  1,
                  length(f) - 2) || '01'
WHERE substr(f,
              -2) = '00';If most of the rows have pattern '%00':
UPDATE A
SET    f = SUBSTR(f,
                  1,
                  length(f) - 2) ||
           DECODE(SUBSTR(f,
                         -2),
                  '00',
                  '01',
                  SUBSTR(f,
                         -2));
