How to make WebContextAdapter as Null

String Name = WDWebContextAdapter.getWebContextAdapter().getRequestParameter("firstName");
String Name2 = WDWebContextAdapter.getWebContextAdapter().getRequestParameter("lastName");
Hi
     After passing the parameters above  i want to make make the Adapter
     to  null again. 
     What are the possible ways for that, plz reply asap.
regards
jalandhar

I am navigating through my application based on the contents of the adapter.. But once the WDWEBCONTEXTADAPTER is set, even if i carry out the statement
IWDWebContextAdapter adapter = WDWebContextAdapter.getWebContextAdapter();
adapter.getRequestParameter("Name1");
adapter = null;
It returns the same value previously set by the previous portal navigation which i wont require..
Thats the reason i need to make the initial WDWebContextAdapter.getWebContextAdapter() go null and hence return me no value the second time its being checked..

  • How to make allow null for a column in all table.

    Hi,
    I have a column "col1" in all tables (user made table) , i want to make it allow null
    please tel me how can it be done using single script.
    i mean in short way.
    yours sincerely.

    yes. absolutely you can.
    Look, what i got -
    Ranit>>  select 'alter table ' || table_name || ' modify("TIMESTAMP" null) ; ' from user_tab_columns where column_name='TIMESTAMP' and nullable ='N';
    'ALTERTABLE'||TABLE_NAME||'MODIFY("TIMESTAMP"NULL);'                           
    alter table FIXED_OBJ$ modify("TIMESTAMP" null) ;                              
    alter table SUMPARTLOG$ modify("TIMESTAMP" null) ;                             
    alter table SUMDELTA$ modify("TIMESTAMP" null) ;                               
    alter table ALL_SUMDELTA modify("TIMESTAMP" null) ;                            
    alter table DBA_EXP_FILES modify("TIMESTAMP" null) ;                           
    alter table WRI$_DBU_CPU_USAGE modify("TIMESTAMP" null) ;                      
    alter table DBA_CPU_USAGE_STATISTICS modify("TIMESTAMP" null) ;                
    7 rows selected.But, it is not over.
    Either - You have to do an 'EXECUTE IMMEDIATE' over these 'alter' scripts.
    OR - Take these scripts, put it into a <script_name>.sql file and then execute this file.
    Hope you understand.

  • How to make a Struts message null after used in JSP?

    Hi,
    In the context of Struts/JSP,
    An action class might write error messages by
    ActionError msg = new ActionError("msg.request.something");
    ActionErrors msgs = new ActionErrors();
    msgs.add(ActionErrors.GLOBAL_ERROR,msg);
    saveErrors(request,msgs);
    This message will produce a popup modal window by the following JSP code:
    <logic:messagesPresent>
    <html:messages id="error">
    <!--<li class="infomsg"><bean:write name="error"/></li> -->
    <script>javascript:alert('<%=error%>')</script>
    </html:messages>
    </logic:messagesPresent>
    The problem is that this JSP page is shared by serveral actions: when another action invoke this page again, the previous error message will take effect again.
    So my question is how to make message null after used once by its author.
    Thx.
    PY

    msgs = null;

  • How to make a JPanel selectable

    When extending a JPanel and overriding the paintComponent() method the custom JPanel can not be selected so that it gets for example KeyEvents.
    But if I make the new Class extend a JButton it gets of course selected and able to receive for example KeyEvents.
    My question is therefore; what does the JButton implement that a JPanel doesn&#8217;t so that a JButton gets selectable? Or in other words; how to make a JPanel selectable?

    Try this extended code. Only the first panel added can get the Focus.

  • How to make a pop up within if else

    I'm now making an user interface which will be used to control a remote robot. I want to make it so that when a button is pressed, a window will pop-up and tells the user what the robot is doing. At the moment, I can only make it to show the message in the cmd box. Code is as follow:
    class ActionHandler implements java.awt.event.ActionListener
              public void actionPerformed(java.awt.event.ActionEvent event)
                   Object object = event.getSource();
                   if (object == forwardButton) {
                        System.out.println("Robot moving fordward");
                   else if (object == backwardButton) {
                        System.out.println("Robot moving backward");
                   else if (object == rotateLeftButton){
                        System.out.println("Robot rotating to its left");
                   else if (object == rotateRightButton){
                        System.out.println("Robot rotating to its right");
    The only way to make pop-up which I know is this one:
    import javax.swing.*;
    public class DisplayTextInWindow {
         public static void main(String[] args) {
              // create a String variable
              String messageText = "Hello world";
              // display it in the console window
              System.out.println(messageText);
              // now display it in its own window
              JOptionPane.showMessageDialog( null, messageText );
    Which I can put into the code for interface because I can't start another class within an if statement (as far as I know anyway...)
    Can anyone please teach me how to make a pop-up within an if else statement?

    Which I can put into the code for interface because I can't start another class within an if statement (as far as I know anyway...)yes you can.
    if (robotRotating)
        newClass class = new newClass();
        class.methods;
    Can anyone please teach me how to make a pop-up within an if else statement?sure
    if (robotRotating)
       //i think this part is already answered in the previous post
       javax.swing.JOptionPane.showMessageDialog(null, "your message here", "your title here", JOptionPane.OK_OPTION);

  • How to make a stationery out of .doc or .docx file?

    Hi,
    I stumbled upon a website that has some nice stationery, in .doc format. and since there few free pre made stationery available for Mail.app, at least to my knowledge, because I think I almost downloaded every free stationery available out there that could be easily found via Google. I decided to download some of these .doc stationeries and try to put them in Mail.app, but first I had to convert them into .html format. so here is what I've already tried and did not work:
    first I tried opening them in TextEdit, which supports .doc out of the box, only to find out that the pictures in the documents are gone to thin air. I tried saving it and then opening it with something else like Open Office, but the pictures were permanently gone.
    then I tried opening the original documents directly in Open Office, you guessed right If you said they will look screwed, and they were, and tried to save them as html, they were screwed even more.
    so I did a bit of research and found out that I could use Google Docs in order to convert the documents, I uploaded them into my Google docs and then tried to open them with it, but found it that Google docs can't handle the pictures (specially background pictures) either. as a result I did more searching to find a document converter and here is what I found:
    I found a few online service to convert these documents:
    http://www.freefileconvert.com/ was pretty good to convert the files into an .odt format. at first I thought yes I got the solution, now I can simply convert it to html using Open Office, but unfortunately, when I saved the document in html format and checked it in Safari to see how does it look, as If I would have done the same in MS Office with the original format, it looked pretty much screwed .
    So I continued to look and I found a few other online services one of them asked me to pay a fee, I skipped to the other one which was http://docx-converter.com/. unfortunately the website wasn't functioning properly I think, at least for me (maybe someone out there has succeeded using it, I don't know.) and it didn't send me anything.
    Finally I found http://www.zamzar.com/ that could convert .doc or .docx documents into html, or at least that is what it claims to do so, I tried it, and after I received the file via email, I found out it only contains a bmp image of the document's background. So much for the online conversion services!
    But I decided I would give it a last shot using MS Office online, so I opened up my old Windows Live mail and went into my Skydrive, I uploaded the documents and tried saving it as html, but there were no save as html (after all an online copy of MS Office should have some limitations, otherwise few people will be willing to buy a Desktop version) but this didn't made me disappointed, since I already knew, that Neither Office Word can make a clear conversion, so I tried something different, while I was in Safari looking at the document in online MS office, I saved the page as Web Archives, then I opened the file with TextEdit, and after deleting useless links and pictures, I finally managed to get a clear document with everything that supposed to be in it. At this point I only need to know how to make use of this document to create a stationery with this raw file which is in Web Archive format. any ideas?
    null

    I'm a total idiot! How did I overlook http://www.zamzar.com/ functions? I think I might have mistakenly chosen convert to BMP instead of html. I tried it and the result was very good.
    OK I finally found a good solution for this problem, so everyone out there that has the same problem, here is what I did:
    1. OK if you have some .doc and .docx file formats and you want to convert them into something like .html or .odt, without having to reedit the code or getting a screwed document, use http://www.freefileconvert.com/ in order to convert them into .odt so they would look as they do in MS office just go to the website and upload your documents then choose .odt, then click convert, after a few moments you will get a link to download your .odt files. you can use and play around with your document in Open Office, I have tested it and it's really good.
    2. Or if you want to convert them into .html with a clean code, and all the elements in it, simply go to http://www.zamzar.com/ and then ulpoad your documents, choose .html and enter your email address, you will have your .html files zipped and sent right in your inbox, then you could use Kompozer like me, or any other html editor, to make a template out of it. I tried it and the result was nice, now I have a bunch of nice html files that I can use to make templates and email stationery.

  • How to make a Java program that recognises a function of two variables...

    How to make a Java program that recognises a function of two variables to assign values to that?
    First I will give an example and then do the question.
    Ex1.
    We have any function, eg.y = x ^ 2 + 1 (read 'y' equals 'x' high to the square), a function of the second degree.
    To build the graph of this function attach values to 'x' to find the values of 'y'
    And thus mount the pair ordered (x, y) which represents a point on the Cartesian plane.
    Assigning values to 'x' 'we can build up a table that gives us the pairs ordered:
    We can use any numbers, but arfer interval [-3.3]
    X | y = x ^ 2 + 1
    -3 | Y = (-3) ^ 2 +1 = 10
    -2 | Y = (-2) ^ 2 +1 = 5
    -1 | Y = (-1) ^ 2 +1 = 2
    0 | y = (0) ^ 2 +1 = 1
    1 | y = (1) ^ 2 +1 = 2
    2 | y = (2) ^ 2 +1 = 5
    3 | y = (3) ^ 2 +1 = 10
    We then ordered the pairs:
    (-3.10), (-2.5); (-1.2), (0,1), (1,2), (2,5), (3,10)
    Tabem that can be represented by a table:
    X | y
    -3 | Y = 10
    -2 | Y = 5
    -1 | Y = 2
    0 | y = 1
    1 | y = 2
    2 | y = 5
    3 | y = 10
    Now I begin to explain my doubts.
    See this program:
    Ex2
    * To change this template, choose Tools | Templates
    * And open the template in the editor.
    Encontrando_o_valor_de_y package;
    * @ Author des Soldat Gottes
    Import javax.swing.JOptionPane;
    Public class (Main
    * @ Param args the command line arguments
    Public static void main (String [] args) (
    Int x, y;
    String x1;
    X1 = JOptionPane.showInputDialog ( "We have the function y = x + 1 \ n" +
    "Assign a value for 'x',"); / / receives a value for the function y = x + 1
    X = Integer.parseInt (x1); / / tranforma String in int
    Y = x + 1; / / receives the value of 'x' and calculates' y '
    JOptionPane.showMessageDialog (null, "The value of 'y' is: \ t \ t" + y);
    / / Displays the value of 'y'
    System.exit (0);
    We see that the program receives above a value for 'x' and replaces the function contained in the program, y = x + 1, and so is the value of the variable 'y'.
    In: x1 = JOptionPane.showInputDialog ( "We have the function y = x + 1 \ n" +
    "Assign a value for 'x',");
    The entry is a number and that number is assigned aa ja existing function in the (y = x + 1).
    The question is: would it be possible to come to a function?
    Ex: the program ask: DIGITE THE FUNCTION?
    The USUARIO DIGITARIA A FUNCTION ANY, TYPE: y = x ^ 2 +1
    The program would recognize the function and give numerical values to that function as Ex1, at the beginning of this text.
    And then to find the values of the x and y launch a table.
    It would be possible that?
    By invez of entering with a number so that the program sustitua a function ja existing as Ex2, seen above, entering with a function quaquer (type: y = x ^ 2 +1) for the program atribuisse values to that function and then create a table of values as Ex1.
    I hope it has been easier to understand my doubts now.
    Thank you for your attention!
    God bless!

    Thanks for the explanation, could understand what fly said.
    But as it applied to a program?
    How to create a program that recognizes that the entry coefficients?Are you asking about how to parse out the coefficients from the string "3x^4 + 4x^3 - 8x^2 + 5x^1 + 2x^0"? If you define the format to strictly follow that example, this should get you started:
    Strip out the spaces
    Split the String on "x^"
    That should give you [3, 4+4, 3-8, 2+5, 1+2, 0]
    Split each resulting String on "+ | -", preserving the operator as a token so you can apply the correct sign to the coeff.
    That should leave you with [3, 4, +, 4, 3, -, 8, 2, +, 5, 1, +, 2, 0]. Every other number is a coeff, the rest are the degrees.
    You can strip out the +, since those coeffs are already positive, and strip out the - after negating the following number. This is all assuming that you have to write this yourself. There is no doubt already a library or 5 out there that does this for you.

    Well working is good...
    The code itself is less than spectacular I'm afraid. There is very little
    OOness to this. For your future reference when you complete a program
    and it consists of nothing but static methods you have done something
    incorrectly.
    As far as the code you do have goes some refactoring would be nice.
    The two main methods you have (proj1 but especially processData) are
    too long and unwieldy. processData seems to be a program in an of
    itself. It's complicated and hard to follow.
    My recommendation to you would be to read this http://java.sun.com/docs/books/tutorial/java/index.html
    Especially focus on the sections dealing with explanation of Object
    programming. These terms and concepts can certainly be confusing to
    new programmers so you may also want to consider finding yourself a
    tutor to help you get a better grasp of these concepts.
    In short if it works that's good. And it's also good to see that you put the
    effort and time in that you have. However if I was grading your project
    I'd give it a C- at best because this is a Java program in syntax only.
