How to fill a table with data from columns & rows from a txt file

I am trying to fill say:
Myname Myclass Mycollege
Mohan MD Stanford
from a txt file into 3 columns of a table. I can easily do it into a textarea component by
clicking a button:
try{
FileReader fr = new FileReader("F:/CreatorProjects1/stan.txt");
BufferedReader br = new BufferedReader(fr);
String s1="";
String s="";
stantxtarea.setValue(s);
while((s=br.readLine())!=null) {
s1 = s1+s;
s1=s1+"\n";
stantxtarea.setValue(s1);
br.close();
fr.close();
} catch(Exception e) {
e.printStackTrace();
return null;
All table components seem to need a database. I do not use any database. I run exe files that give output to txt files. How to solve it?
I appreciate any help in this regard...

there may be another way. This is some thing some thing I can recommend. You can create property type of ObjectListDataProvider in session or application based on the scope you required. Create web bean class with property you want to show in the column (say col1, col2, col2). Initialize the list property like similar below
List dataList = new ArrayList();
ObjectListDataProvider mytableprops = new ObjectListDataProvider();
try {
//start loop read data from your txt file
//create instance of web bean for each line
//add web bean instance into dataList
//end of loop readind data from txt file
oldpins.setList(dataList );
oldpins.setObjectType(NotificationProfileBean.class);
} catch (Exception ee1){;}
return oldpins;

How to display checkbox that retrieve value from database?

Hi,
I have a problem, hope someone will help me.
The problem is, I have 3 checkbox where contain different values.
I will insert the values to db in array. When I retrieve the values, I got a problem to display it.
Let say,my checkbox's value is:
1.car
2.bus
3.lorry
when I checked car and lorry, my array will be [car,bus] insert to db.
For editing purpose, I need to display the checkbox again with the values from db. So, it should be :
1.car (checked)
2.bus (checked)
3.lorry (unchecked)
I can display the car and bus (checked) , but not the unchecked checkbox. Sometimes, it's repeating, car (checked) and car (unchecked) will display.
Anybody have a suggestion?
My codes:
String[] list = {"car","bus","lorry"};
String[] logtype ={"car","bus"}//retrieve from db (example)
for (int i=0;i<logtype.length;i++){
if (logtype.equals(list[i]){
<input type="checkbox" name="type" value="<%=list[i]%>" checked>
else{
<input type="checkbox" name="type" value="<%=list[i]%>" >

hey u can solve this problem by using vector instead of array
here's the code
<%
Vector list=new Vector();
list.addElement("car");
list.addElement("bus");
list.addElement("lorry");
Vector logtype=new Vector();
logtype.addElement("car");
logtype.addElement("bus");
for(int i=0;i<list.size();i++)
     if(logtype.contains(list.elementAt(i)))
     { %>
          <%=list.elementAt(i)%><input type="checkbox" name="type" value="<%=list.elementAt(i)%>" checked>
     <%}
     else
     {%>
          <%=list.elementAt(i)%><input type="checkbox" name="type" value="<%=list.elementAt(i)%>" >
     <%}
%>

Filling a column with value from other columns

Hello all!
Suppose i have the following table:
TableA(col_one int, col_two int, result int);I want to insert value to col_one and col_two, and result will be filled with the multiplication product of col_one and col_two.
ok firstly i know this is very redundant way of storing data and generally should not be used, but one case when this might come in handy is when we want to store a total payment amount of product price and quantity. this can be useful since product price can change overtime and we need to record the data as the transaction happens to avoid change in total payment over time (as the price drops or rises).
now with the problem:
I tried this in mysql and it works:
INSERT INTO TableA (col_one, col_two, result) VALUES (30, 20, col_one * col_two);but not in oracle, which output the following error:
>
ora 00984 column not allowed here
any idea on how to do it in oracle?
thank you very much :)
ps, thank you for the fast replies on my previous topic.

If the insert is done inside PL/SQL you can return the primary key for the row (assuming the table has a primary key?!?) and then update based on that key, but this still introduces two statements where a single statement can suffice.
Why are you thinking so complicated? ;-)
If it is done in PL/SQL the you can do this:
create procedure addRow(p_value1 number,p_value2 number) is
p_result number;
begin
p_result:=p_value1*p_value2;
insert into table1 (col_one,col_two,result) values(p_value1,p_value2,p_result);
commit;
end;If you want to do this automatically when someone inserts a row (without providing the result) you have to use an insert trigger.

How to update this table with values from another table ?

Hi
I have a table "regies". I want to replace the values of the column "regies.agent" by the value of the column "regies_personnes.id"
As you see the tables have a common values column. ie regies.agent = regies_personnes.nom
Table "regies" :
Insert into "regies" (AGENT) values ('Humberdot Alain');
Insert into "regies" (AGENT) values ('Danard Patrick');
Table "regies_personnes" :
Insert into REGIES_PERSONNES (NOM,ID) values ('Humberdot Alain',1);
Insert into REGIES_PERSONNES (NOM,ID) values ('Danard Patrick',2);
Before we have this
sql>select agent from regies ;
Humberdot Alain
Danard Patrick
After the update, the result should be
sql>select agent from regies ;
1
2
Thank you for your kind answer.

You will face error if you have duplicates
ORA-01427 Single row subquery returns Multiple rows.Try this way
create table regies(agent varchar2(30));
create table regies_personnes( nom varchar2(30),id number);
Insert into regies (AGENT) values ('Humberdot Alain');
Insert into regies (AGENT) values ('Danard Patrick');
Insert into REGIES_PERSONNES (NOM,ID) values ('Humberdot Alain',1);
Insert into REGIES_PERSONNES (NOM,ID) values ('Danard Patrick',2);
Insert into regies (AGENT) values ('Humberdot Alain');
Insert into regies (AGENT) values ('Danard Patrick');
Insert into REGIES_PERSONNES (NOM,ID) values ('Humberdot Alain',1);
Insert into REGIES_PERSONNES (NOM,ID) values ('Danard Patrick',2);
commit;
update regies r set agent = (select id from regies_personnes p where r.agent = p.nom
and rownum=1)
where exists (select id from regies_personnes p where r.agent = p.nom

Dynamically fill area with words from list

hello all,
i would like to fill the entire area of a flash movie with
words.
the movie starts out blank, but as time goes on the visible
area fills with words from a pre-written list.
ideally, the height and width of the words is randomized
within a range i determine.
i wouldn't mind being pointed to a tutorial that shows how to
fill an area with randomly-sized rectangles, that might help.
eventually, i want to be able to control the speed of the
area being filled with an input device (mouse or external sensor)
but first things first!
am using flash 8.
thank you,
aya.

You may want to check this out. It fills a space with words
and keeps filling the empty space. I'ts open source so you can take
peak inside.

Create xml file with values from context

Hi experts!
I am trying to implement a WD application that will have some input fields, the value of those input fields will be used to create an xml file with a certain format and then sent to a certain application.
Apart from this i want to read an xml file back from the application and then fill some other context nodes with values from the xml file.
Is there any standard used code to do this??
If not how can i do this???
Thanx in advance!!!
P.S. Points will be rewarded to all usefull answers.

Hi,
you need to create three util class for that:-
XMLHandler
XMLParser
XMLBuilder
for example in my XML two tag item will be there e.g. Title and Organizer,and from ur WebDynpro view you need to pass value for the XML tag.
And u need to call buildXML()function of builder class to generate XML, in that i have passed bean object to get the values of tags. you need to set the value in bean from the view ui context.

How Can I get multi column values from dynamic search help?

Hi Gurus;
I'm using dynamic search help in my program.
I want to get multi column values from search help. But I dont know solution for this issue.
I'm using F4IF_INT_TABLE_VALUE_REQUEST FM.
How Can I get multi column values from dynamic search help?
Thanks.

Believe it or not, the same FM worked for me in a dynpro. I will try to explain here how it works in custom screen and then you can do your work for other screens or program types. I am not going to write my actual work but will explain in general.
I have 4 fields (FLD1, FLD2, FLD3, FLD4) and i made the search based on FLD2 and when user click on a line (could be any field), then this would bring the line on to the screens.
There are like 3 steps.
You have your value_tab for my fields FLD1, FLD2, FLD3 and FLD4. This is just the data that we pass into the FM. (data: IT_VALTAB type table of ZVAL_TABLE)
Next map the screen fields into an internal table (data: It_dynpfld type table of dselc ). I also have other internal tables defined (just to keep it straight, i will be putting here) data: It_return type standard table of ddshretval.
Next step is to call the function module. Make sure you have values in IT_VALTAB.
call function 'F4IF_INT_TABLE_VALUE_REQUEST'
exporting
        retfield        = 'FLD2'
        value_org       = 'S'
      tables
        value_tab       = It_VALTAB
        return_tab      = It_return
        dynpfld_mapping = It_dynpfld
      exceptions
        parameter_error = 1
        no_values_found = 2
        others          = 3.
    if sy-subrc <> 0.
      message id sy-msgid type sy-msgty number sy-msgno
      with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
    else.
      perform get_selected_fields tables It_return.
    endif.
The code within the perform GET_SELECTED_FIELDS - We need to map the result fields after user selects it. The code goes like this. This is step is to update the dynpro fields.
I need a internal table as well as a work area here. like,
data: lt_fields type table of dynpread,
        la_fields type dynpread.
field-symbols: <fs_return> type ddshretval.
so fill out LT_FIELDS from the IT_RETURN table
loop at lt_return assigning <fs_return>.
    la_fields-fieldname = <fs_return>-retfield.
    la_fields-fieldvalue = <fs_return>-fieldval.
    append la_fields to lt_fields.
    clear: la_fields.
endloop.
Call the FM to update the dynpro
call function 'DYNP_VALUES_UPDATE'
    exporting
      dyname               = sy-repid
      dynumb               = '1002' "This is my screen number. You could use 1000 for selection screen (hope so)
    tables
      dynpfields           = lt_fields
    exceptions
      invalid_abapworkarea = 1
      invalid_dynprofield = 2
      invalid_dynproname   = 3
      invalid_dynpronummer = 4
      invalid_request      = 5
      no_fielddescription = 6
      undefind_error       = 7
      others               = 8.
if sy-subrc <> 0.
    message id sy-msgid type sy-msgty number sy-msgno
            with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
endif.
good luck

Oh dear. I don't think anybody can advise you until you are not "kinda" new to Java anymore. Learn Java itself (the language, the platform and the tools), only then should you start considering going into web development.

        if (connection != null) {
          try {
            Statement s = connection.createStatement();
            String sql = "select ID from floor order by ID asc";
            try {
              ResultSet rs = s.executeQuery(sql);
              try {
                while (rs.next()) {
                  floornumbers.add(rs.getInt(1));
              finally { rs.close(); }
            finally {s.close(); }
          catch (SQLException e) {
            System.out.println("Could not get floor numbers: " + e.getMessage());
          finally {
            dataManager.putConnection(connection);
        return floornumbers;
     } The classes compile properly, but when I load this page up in Tomcat it just freezes and does not load the form. I tested the DB connection and it works fine.
What am I doing wrong in the JSP code?
Thanks for the help in advance.
UPDATE: I commented out the form, and added <%=floornumbers.size()%> right above the commented code to check if the ArrayList is indeed getting populated with the values from the database (the values are of type integer in the database). The page still freezes like before. I'm puzzled now :confused: .

Wrong usage of Iterator.

         
         <% ArrayList<Integer> floornumbers = dataManager.getAllFloorNumbers();
            Iterator<Integer> iterator = floornumbers.iterator(); %>
         
         <form id="floorselectionform">
              <input type="hidden" name="action" value="floorselected"/> 
              Select floor | <select name="floorselector" id="floorselector">
                   <% while (iterator.hasNext()) {
                                Integer inte = iterator.next();
                        %>
                   <option value="<%=inte.intValue()%>"><%=inte.intValue()%></option>
                   <% } %>
              </select>
              <input type="submit" value="Go!"/>
         </form>or make use of enhanced loop as you are already using J2SE 5.0+ for avoiding confusions.

         
         <% ArrayList<Integer> floornumbers = dataManager.getAllFloorNumbers(); %>
         
         <form id="floorselectionform">
              <input type="hidden" name="action" value="floorselected"/> 
              Select floor | <select name="floorselector" id="floorselector">
                   <% for(Integer inte:floornumbers) {%>
                   <option value="<%=inte.intValue()%>"><%=inte.intValue()%></option>
                   <%}%>
              </select>
              <input type="submit" value="Go!"/>
         </form>and a lot better thing would be making usage of basic Taglib provided with JSTL spec or struts spec which make life easier and simple.
something like usage of <c:forEach/> or <logic:iterate/> would be lot better without writing a single scriptlet code.
Hope that might help :)

Fill JComboBox with Vector from database

Hi there,
I have a problem with filling a JComboBox with data from a database. I can print the data in the console, but it seems to be impossible to do it in a ComboBox ...
I tried this:
* To change this template, choose Tools | Templates
* and open the template in the editor.
*package client;*
*import data.Raum;*
*import data.RaumImpl;*
*import java.net.MalformedURLException;*
*import java.rmi.Naming;*
*import java.rmi.NotBoundException;*
*import java.rmi.RemoteException;*
*import java.sql.SQLException;*
*import javax.swing.JComboBox;*
*import javax.swing.JFrame;*
*import java.util.Vector;*
*import verwaltung.*;
import server.DraServer;
* @author philipp
public class ComboBox extends JFrame
    ComboBox(String title) throws RemoteException, SQLException, NullPointerException, MalformedURLException, NotBoundException {
    super(title);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    DraVerwaltung verwaltung = (DraVerwaltung) Naming.lookup ("rmi://localhost/DRA");
    System.out.println("Remote object created...");
    Vector raeume = verwaltung.RaumAusleser();
    Raum r;
    for (int i = 0; i < raeume.size(); i++)
        r = (Raum)raeume.elementAt(i);
//      System.out.println ("Raum: " + r.getRaumname());
//      System.out.println ("Raumid: " + r.getIdRaum());
     JComboBox jcb = new JComboBox(r.getRaumname());
    getContentPane().add(jcb);
    setSize(200, 50);
    setVisible(true);
public static void main(String[] args) throws RemoteException, SQLException, NullPointerException, MalformedURLException, NotBoundException {
    new ComboBox("Test");
}In this case I get the following for JComboBox (line 44):
"cannot find symbol
symbol: constructor JComboBox(java.lang.string)
location: class javax.swing.JComboBox"
I tried:
-> change "JComboBox jcb = new JComboBox(r.getRaumname());" to "JComboBox jcb = new JComboBox(raeume);"
then I got the JComboBox, but with ... I don't know how to describe the content. It seems like a (very long) reference.
All other tries can't be tested, because I got the problem with constructor again.
I'm happy for an early response.
Regards

Now, it works!
It looks like that:

    DraVerwaltung verwaltung = (DraVerwaltung) Naming.lookup ("rmi://localhost/DRA");
    System.out.println("Remote object created...");
    Vector raeume = verwaltung.RaumAusleser();
    Raum r = new RaumImpl();
    Vector vJcb = new Vector();
    for (int i = 0; i < raeume.size();i++){
        r = (Raum)raeume.elementAt(i);
        vJcb.add(r.getRaumname());
    JComboBox jcb = new JComboBox(vJcb);
    getContentPane().add(jcb);
    setSize(200, 50);
    setVisible(true);
    public static void main(String[] args) throws RemoteException, SQLException, NullPointerException, MalformedURLException, NotBoundException {
       new ComboBox("Combo box Demo1");
}Thanks in advantage to all!
