How to delete User-Agent header field from http request ?

Hi,
I'm currently using HttpUrlConnection to create a HTTP 1.1 POST client, and I wish to remove the User-Agent field from my request.
However, java seems to set this field to "java.1.4.2" if none is provided.
I have found methods to modify the User-Agent ( "setRequestProperty()" and system property "http.agent" ) but none to delete it.
Is there a way to remove this header from the request ?
This field is said as "should be implemented" but is not required in rfc2616(http1.1), so I'm a bit surprised that I can't remove it in the java HttpUrlConnection...
Thank you for your help,
Gregoire

You can always go around java.net.HttpUrlConnection with your own subclass of UrlConnection or simply a socket. You may lose some functionality, for example with handling binary content, but it may still be a solution.
(But are you saying that the server requires that there's no user-agent header? That's not a case of incompatibility, it's a bug. Scrap the server, and get one that works.
It seems a lot more likely that the server just have strict ideas of what user agents it wants to talk to. Then instead of removing the header, you want to find out what values the server will expect.)

How to transfer user defined accounting fields from SRM to ECC ?

Hi!
We are running SRM 5.0 and ECC 6.0 with classic scenario.
We have defined Business entity filed account assignment tab in SRM SHC.
New fields are also defined in tables BBP_C_ACC_F and in BBP_C_ACCFD and added in the structure also INCL_EEW_PD_ACC_CSF. New fields are also defined in srpo accounting.
In R/3 the same field is already defined as it is standard one.
When I create PR or PO i entered the Business entity for the account assignment R i.e real estate.
However, when I order my shopping cart with values in new fields, the values are not transferred into backend.
Standard fields transfer nicely, but the user defined fields dont transfer.
Can any please let me know what we have to do for these user defined values to transfer to back end. We need to implement any BADI ?
Please let me know
Thanks

How can I get the "text" field from the actionEvent.getSource() ?

I have some sample code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.util.ArrayList;
public class JFrameTester{
     public static void main( String[] args ) {
          JFrame f = new JFrame("JFrame");
          f.setSize( 500, 500 );
          ArrayList < JButton > buttonsArr = new ArrayList < JButton > ();
          buttonsArr.add( new JButton( "first" ) );
          buttonsArr.add( new JButton( "second" ) );
          buttonsArr.add( new JButton( "third" ) );
          MyListener myListener = new MyListener();
          ( (JButton) buttonsArr.get( 0 ) ).addActionListener( myListener );
          ( (JButton) buttonsArr.get( 1 ) ).addActionListener( myListener );
          ( (JButton) buttonsArr.get( 2 ) ).addActionListener( myListener );
          JPanel panel = new JPanel();
          panel.add( buttonsArr.get( 0 ) );
          panel.add( buttonsArr.get( 1 ) );
          panel.add( buttonsArr.get( 2 ) );
          f.getContentPane().add( BorderLayout.CENTER, panel );
          f.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
          f.setVisible( true );
     public static class MyListener implements ActionListener{
          public MyListener() {}
          public void actionPerformed( ActionEvent e ) {
               System.out.println( "hi!! " + e.getSource() );
               // I need to know a title of the button (which was clicked)...
}The output of the code is something like this:
hi! javax.swing.JButton[,140,5,60x25,alignmentX=0.0,alignmentY=0.5,
border=javax.swing.plaf.BorderUIResource$CompoundBorderUIResource@1ebcda2d,
flags=296,maximumSize=,minimumSize=,preferredSize=,defaultIcon=,disabledIcon=,
disabledSelectedIcon=,margin=javax.swing.plaf.InsetsUIResource[top=2,left=14,bottom=2,
right=14],paintBorder=true,paintFocus=true,pressedIcon=,rolloverEnabled=true,
rolloverIcon=,rolloverSelectedIcon=,selectedIcon=,text=first,defaultCapable=true]
I need this: "first" (from this part: "text=first" of the output above).
Does anyone know how can I get the "text" field from the e.getSource() ?

System.out.println( "hi!! " + ( (JButton) e.getSource() ).getText() );I think the problem is solved..If your need is to know the text of the button, yes.
In a real-world application, no.
In a RW application, a typical need is merely to know the "logical role" of the button (i.e., the button that validates the form, regardless of whether its text is "OK" or "Save", "Go",...). Text tends to vary much more than the structure of the UI over time.
In this case you can get the source's name (+getName()+), which will be the name that you've set to the button at UI construction time. Or you can compare the source for equality with either button ( +if evt.getSource()==okButton) {...}+ ).
All in all, I think the best solution is: don't use the same ActionListener for more than one action (+i.e.+ don't add the same ActionListener to all your buttons, which leads to a big if-then-else series in your actionPerformed() ).
Eventually, if you're listening to a single button's actions, whose text change over time (e.g. "pause"/"resume" in a VCR bar), I still think it's a bad idea to rely on the text of the button - instead, this text corresponds to a logical state (resp. playing/paused), it is more maintainable to base your logic on the state - which is more resilient to the evolutions of the UI (e.g. if you happen to use 2 toggle buttons instead of one single play/pause button).

How to delet the credit card details from apple id account

how to delet the credit card details from apple id account

On your computer's iTunes you should be able to edit your payment info by going into the Store > View Account menu option and logging into your account, and on your account's details page there should be a payment link. If you are doing it on your phone then tap on your id in Settings > iTunes & App Store and tap on 'View Apple ID' on the popup and log into your account - that should also give you a payments link on your account's page.
Changing payment info : Change or remove your payment information from your iTunes Store account (Apple ID)
If you don't get the 'none' option on the payment details screen : Why can’t I select None when I edit my Apple ID payment information?

Get a specific Http header field from an http request in a component

Hello,
In a custom component that I've created ( which extends ServiceHandler), I'd like to access a specific http header field from the http requests that this component receives.
I assume this could be accessible through m_binder or m_service, but I didn't find any solution so far.
Any Idea?
Thanks in advance,
Leo

As it may help others, I answer what I figured out.
Every details of the http request is put into the m_binder.
So a specific field can be accessed with m_binder.getEnvironmentValue("My_data")
You can also list all the available data as it is a standard properties set.

How to Set User-Agent in UIWebView?

I tried to change User-Agent using NSMutableURLRequest in the UIWebView delegate function, but didn't work. The funny thing is...the User-Agent string changed if the request is redirect. Have anyone experienced it? I want to change User-Agent of every request from UIWebView to the same like coming from Safari browser. Please HELP!!

I would try the Apple Developer Connection, this forum is for users of the iPhone, you aren't going to get much help with this.

Accessing Message Header fields from envelope

I am doing an interface with the RNIF adapter. They want me to pull the delivery header information, which is in the RNIF envelope, not the payload document and map it into some fields that exist in the inbound schema. Can this be done in message mapping? I would suppose that this question would apply if one wanted message header fields from the SOAP envelope also.
Kind Regards,
Chris

How can delete the serve.bannersdontwork virus from Safari on Mac?

Hello @all,
How can delete the serve.bannersdontwork virus from Safari on Mac?
About every 8-20 clicks Safari opens a webside named serve.bannersdontwork.
I can not remove this with my Avira antivirus programm.
Can anybody help me?
THX
Hallo an alle,
Ich habe mir einen Virus eingefangen, serve.bannersdontwork, auf Safari.
Alle 8-20 clicks öffnet sich diese Seite "serve.bannersdontwork" und leitet mich auf andere weiter.
Über mein Antivirusprogramm Avira konnte ich den Virus nicht beheben.
Auch die erweiterung AdBlock hilf hier nicht weiter.
Wer weiß, oder hat eine Ahnung, wie man diesen Virus wieder los wird?
Danke schonmal im voraus!!

From the Safari menu bar, select
Safari ▹ Preferences ▹ Extensions
Turn all extensions OFF and test. If the problem is resolved, turn extensions back ON and then disable them one or a few at a time until you find the culprit.
If you wish, you may be able to salvage the errant extension by uninstalling and reinstalling it. Its settings will revert to their defaults. If the extension still causes a problem, remove it permanently or refer to its developer for support.

How to delet photos that were downloaded from the computer?

Resync the iPad with the computer, but before doing so, click on the device once it is hooked up to iTunes. You will see the Device Profile to the right with several tabs - Photos being one of them. Select the Photos tab, and either uncheck the Sync Photos box at the top (if you don't want any of the photos to be on your device), or uncheck the selected photos you no longer want to sync.

Informative thread indeed. Wish I saw it early enough. Managed to come up with the code below before I saw this thread.
declare @TTName Table

default 0);
with AvailableTables
(TableSchemaTableName)
as
(select

QUOTENAME(TABLE_NAME)
from
INFORMATION_SCHEMA.TABLES)
insert into @TTName
(TableSchemaTableName)
select *
from AvailableTables
declare @TableSchemaTableName varchar
(500)
declare @sqlstatement nvarchar
(1000)
while 1=1
begin
set @sqlstatement

How to delete master data of materials from sap tables

how to delete master data of materials from sap tables...its needed now.
i know its not recommended but still we need to do this. give me the best possible approach.
regards,
suneetha

Hi,
I would suggest you not to write your own code to delete the entries.
BAPI_MATERIAL_DELETE, this would mark all materials selected for deletion. But still the material would exist in SAP.
Another solution: Delete a material manually and in another session execute the transaction SM04. This would display the tables which get locked when you do the operation, Then you can write your own code to delete the material numbers from all the related tables.
