How to set proxy authentication using java properties at run time

Hi All,
How to set proxy authentication using java properties on the command line, or in Netbeans (Project => Properties
=> Run => Arguments). Below is a simple URL data extract program which works in absence of firewall:
import java.io.*;
import java.net.*;
public class DnldURLWithoutUsingProxy {
   public static void main (String[] args) {
      URL u;
      InputStream is = null;
      DataInputStream dis;
      String s;
      try {
          u = new URL("http://www.yahoo.com.au/index.html");
         is = u.openStream();         // throws an IOException
         dis = new DataInputStream(new BufferedInputStream(is));
         BufferedReader br = new BufferedReader(new InputStreamReader(dis));
      String strLine;
      //Read File Line By Line
      while ((strLine = br.readLine()) != null)      {
      // Print the content on the console

How to set variables values via VBA.

Anybody please help.
How to set variables values via VBA in workbook. SAP Netweaver 2004s.

Pass variable values with VBA and BI 7.0 funtions to Query
At first a remark u2013 Iu2019ve read a lot of threads saying that passing values to a query can be done by using VBA code only. Iu2019ve tested it but Iu2019m not sufficient with the new BEX 7.0 API and therefore I use a mixture of BEX 7.0 funtionality and VBA. I create a BEX 7.0 design item button passing the values to a query u2013 I hide this button somewhere on the sheet or on a hidden sheet and I then raise the event to click the button from VBA code. Works fine and the maintenance is easier if something changes in the API in the future again.
How to start:
Switch to design mode in BEX Analyzer:
Implement a BEX 7.0 design item u201Cbuttonu201D
Click on the button to implement the properties
Make the input for the commands
data_provider = dataprovider_1
cmd = process_variables
subcmd = var_submit
No comes the part with the variables u2013 Letu2019s assume a query has 4 variables but you only want to change 1 with the button u2013 an organizational unit for instance.
Make a range somewhere in the excel with the following structure:
Name    Index   Value
VAR_NAME_1      1       Variablename
VAR_VALUE_EXT_1 1       variablevalue
Value should contain the name of your variable of course and u201Cvalueu201D the value of your variable
Set a name for this range with EXCEL functionality but without the header:
Back to the properties of the button: Insert the name of the range with the variables in the field Command Range:
If you have more variables to process you can of course enhance your Filterrange!
In the left upper Corner you have a name for your button:
Now you can raise the button-click in vba like this:
Application.Run "'" & ThisWorkbook.Name & "'!Sheet2.BUTTON_35_Click"

How to set my favorite tv chanels and view schedule on internet?

How to set my favorite tv chanels and view schedule on internet?

That's a good question - I've been trying since fios came out with fios tv central to view the tv guide online. It keeps saying "invalid user name/password". I've changed them numerous times, contacted online help, talked to phone help (who's also baffled), all to no avail. I actually saw the guide once when I first visited the site, so it exists. Please let me know if you figure out how to get on there because setting the favorites has to be a breeze compared to that.

Hello..how to set classpath....and for environment variables

hello...
i have 2 classes...one.java and Two.java....
In two.java i extends One.java...
Two.java is not compiling....
if I place those 2 files in j2sdk1.4.1/bin folder ..then its compiling successfully.....please help me to solve this..

Perhaps you mean that the java compiler cannot be found in any other directory but the bin directory. You need to add the bin directory to the PATH environmental variable to be able to compile classes anywhere in a command prompt/shell. If you are using windows, you'll find the environmental variables by:
1) right clicking my computer and choosing properties
2) click advanced
3) click environmental variables

How to set FOCUS on applet (java-plugin)

I wrote applet using Java 1.3.1, using swing clasess.
I use java-plugin, defined in <object ..> and <embed ..> tags as described in documentation,
with MAYSCRIPT parameter and ID and NAME parameters defined.
How to set up focus on this applet through JavaScript?
I have tried:
document.embeds[0].focus()
document.applets.MyApplet.focus()
document.objects.MyApplet.focus()
document.objects[0].focus()
document.MyApplet.focus()
But nothing works in my IE5.x or NC4.7. Applet itself works fine.
Is some special methods need to be defined in JApplet to catch the focus?
Thanks for any advice.

Thanks for any advice.With IE you should try the following:
<OBJECT id='MyApplet' ...
document.MyApplet.requestFocus();
This worked fine for me, even without specifying additional "MAYSCRIPT" or "scriptable=true" tags. Obviously this construct managed to call the public Java method "requestFocus()" from JavaScript.
Maybe something similar would also work for Netscape. I felt no need to do this when running in Netscape, because the Netscape browser handled focus management without problems.
For IE I tried to workaround a problem mentioned by several people in this forum: The focus will not be regained by an applet when the user switched form IE to another application and then returns back to the browser window which contains the applet.
Unfortunally the following code fragment worked only partially well:
function activated()
if (isIE)
document.MyApplet.requestFocus();
return true;
window.onfocus = activated();
OnFocus is invoked only each second time when the browser window gains back focus.
I'm still looking for a real solution, so I'd appreciate if anybody could come up with one.
Hope this helps a bit

How to set iframe src from java dynammically

I need to know how to set environment variables from java
I want to set from java for example the environment variable "TestVar" with the value "TestValue"!1) That functionality does not belong in an application. You're trying to set environment variables, which are global across all applications, at either the user level as a whole, or across the entire machine (system level). Or, if you're only trying to set a variable active for the current process, you don't need to do that.
2) Environment variables are not a platform-independent entity, and are thus against the nature of Java.
My gut feel is that you are designing something in a backwards way, so my point is mainly to point that out, not to try to help you solve that particular problem.

How to set mac shortcuts (for mac and windows OS)

i am having a bit of an issue.
i run windows 7 and mac os on the same computer on different hard drives in this computer. i also have a "mac" keyboard. i am not sure how this may be different from a "windows keyboard" but the point is i need to use this keyboard because it matches the one on my laptop which is a mac.
when i switch to windows on this machine i always end up deleting information because the CMD + X and CMD + V cut and paste shortcuts on Mac OS are not the same in windows. windows requires (currently) CTRL + X and CTRL + V. so when i got to cut and paste in windows CTRL + X (this is my habitual way of working) and then i run a CTRL + V i end up writing /over/ the text i selected with a "x" and i end up pasting /over/ the text i selected to paste over with a "v". this is because instead of running a cut and paste, this set of shortcuts in windows simply enters "x" and "y" respectively since the shortcut is not active.
does anyone know where i set these in windows OS and in mac OS?
also, does anyone know if it is possible to set how many UNDOS i can do in either of these OS's or to know how many i can in fact undo?
THANKS
long story background:
1. while i may move to a windows keyboard on the computer i am using (because the mac keyboards these days end up losing keys and they end up very wobbly) i cannot do this for the laptop machine so this may not make a lot of sense if i end up also running windows on the laptop which is my intention at some point.
2. CTRL + X is a very long stretch on the mac keyboard so rather than switching mac shortcuts to accommodate windows shortcuts i am thinking to switch windows shortcuts to mac ATM.
3. this is no small issue! i just went to copy and paste this text so i could save it for myself in order to explain to someone else and i ended up overwriting with a "c". if i had not thought fast and remembered to UNDO by hitting CTRL - X and not CMD - X i might have lost all my work.

long delay - no email of your post here
I also realise that you can use system preferences - Keyboard - modifier keys to make cmd = ctrl or vice versa
I'd surely ask/read elsewhere about altering windows, given the reach issue - but no qualms beyond confusion if switching/using other machines. You might soon find you switch layouts mentally, quite easily.

How to set portal context using Java/JPDK api.

Hi,
I am in the process of converting pl/sql based database provider contect portlets to Java based JPDK. I ran into issue where the database provider portlet users were getting context auto matically. Now with Java/JPDK portlets , I am receiving no data found error, since the context is not set. The pl/sql is setting wwctx_private_api.set_context ('portal') to set the context. From Java if we call this api, it is taking a toll on the performance and the portlet times out.
Can any help how to set the context for a web provider using JPDK or any other better solution. Any immediate help is highly appreciated.
Thanks,
Rav.
