Populate a drop down list with data from Excel and fill in a text field, based on drop down selectio

Hi!
I have a problem with a PDF form: There's a drop down list that I populate with Excel data that I've put in an XML file through an XSD file -- no problem here. The drop down list has a data binding to the XML file, so that a choice in the drop down list can be associated with an object in the XML file. So, when I make a choice in the drop down list, a corresponding object value is fetched from the XML file and put in a text field on the form.
How to do this is described by Stefan Cameron here:
http://forms.stefcameron.com/2006/07/29/dynamic-properties/
There's a snag, though, and to describe it more clearly:
The XML file contains three types of objects: role, role number, and role cost center. Of these I use the first and the third, i.e. the role and the role cost center. The drop down list contains the roles, and when I select a role, the corresponding cost center is filled out in the text field. So far, so good!
But -- if the cost center has the same value for two or more roles, all of these roles "bounce back" into the drop down list, that is, they are all selected in the drop down list. How many of these you can see depend on the height of the drop down list -- if it's low you'll only see the first one.
If I modify Stefan Cameron's data in his example I get the same behavior, so the problem seems to have to do with how XML data are fetched.
I'm sure there's a workaround, but I can't find it! I've spent many hours browsing the web without finding anyone with a similar problem.
Any suggestions appreciated!

Although your issue is far beyond mine, I was hoping you can help me out.....
I need to create a drop down list of names which I wish to somehow link to an Excel spreadsheet.
Please let me know the steps I need to do. I've tried several things, but nothing seems to work and I'm not sure what I am doing wrong.
Thank you

Read data from Excel and write into oracle database

Hi
I want to know how can i read data from excel and write into oracle database using java.Kindly help me out to find a solution.
Thanks and Regards
Neeta

Hai,
I am suggesting the solution.
I will try out and let u know soon.
Make a coma separated file from your excel file.
Assuming that your requirement allows to make a csv file.
This file may be passed as an file object to be read by java.Using JDBC you must be able to populate the data base.You can also use String Tokenizer if needed.
You do not want to go via sql Loader?
For reading the excel file itself do you want java?

Get the data from excel and insert into the database

I want to read the data from excel file, get the data from excel and insert into the database.

You can use the Apache POI HSSF API to read data from Excel files and you can use the Sun JDBC API to insert data in database.
This has nothing to do with JSP/JSTL.

To populate dynamically created int table with data from other table

Hi everybody,
I have already created an internal table dynamically, but now want to populate it with data from another IT depending on the plant name.
My dynamic int table contains fields with plant name like '8001' ,'8002' and so on.
no I want to read data from the other table and depending on bwkey which contains similar data like plant name , want to append to this new dynamic int table through read key statement.
I cannot reference the field name hard coded as it does not allow field symbol reference to be hard coded.
Pls help.

Upload data from excel where one column has text of 3000 characters

Guyz,
I have a query. One of my requirments is to upload data from excel sheet & create a material. In the excel sheet one of the columns has text for BASIC DATA TEXT under ADDITIONAL DATA of a Material. This is a text of running length.
the selection screen has feature of file upload & the users will upload excel files from their respective presentation servers.
Now my problem is that I need a function module which can convert this column in excel sheet into an internal table & later call the BAPI for MM creation.
I have used TEXT_CONVERT_XLS_TO_SAP & when i read my internal table to check this column length, it shows only 255 characters where as data in the excel sheet has 3000 characters (say for eg.)
Can anybody throw some light on this.
Thanks in advance
GPK

Hi,
You can try using this function module and see that whether all your data is coming into the internal table properly.
MS_EXCEL_OLE_STANDARD_DAT
For the other part you needed to convert the internal table data into the structure as need by the BAPI and then call the create BAPI to create the materials in the SAP System.
Hope this helps.
Thanks,
Samantak.

Error while populating drop down list with values from a database

Hi all,
I have a JSP page with a drop down list that is to be populated with values from a database.
This is the code in my JSP file:
     
         
         <% 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()) { %>
                   <option value="<%=iterator.next().intValue()%>"> <%=iterator.next().intValue()%> </option>
                   <% } %>
              </select>
              <input type="submit" value="Go!"/>
         </form>   The DataManager.java class simply forwards this to its respective Peer class, which has the code shown below:
      package seatplanner.model;
    import java.sql.Connection;
    import java.sql.ResultSet;
    import java.sql.SQLException;
    import java.sql.Statement;
    import java.util.ArrayList;
    /* This class handles all floor operations */
     public class FloorPeer
     /* This method returns all the floor numbers */
     public static ArrayList<Integer> getAllFloorNumbers(DataManager dataManager) {
        ArrayList<Integer> floornumbers = new ArrayList<Integer>();
        Connection connection = dataManager.getConnection();
        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 :)

Populating InDesign templates with data from Excel or XML?

I have a client who does a weekly catalogue for computer parts. It’s very detailed and extremely time consuming, and we are looking at moving it to an automated InDesign workflow to save time and money in production. Once imported into InDesign, the resulting file can be exported as a formatted XML document to a webpage for auto formatting.
I know you can import XML directly into InDesign and vice versa. I have created some categories and tables in Excel and exported this as an .xml document. When I import that document into the View > Structure panel, it displays a whole list of attributes but not the actual text I was after.
Any help much appreciated. I’m using InDesign CS4 and doing some research on google at the moment.

Hi CDesign2,
If I understood you correctly, you are either trying to
View your xml data in Adobe LiveCycle form to redit the form???
View your xml data in Adobe acrobat pro
Or wishing to collate updated(new) data into adobe (lifecycle) tracker and view the data set
I suspect points 2, 3 may be the case.
My experience with migrating excel data back to adobe is this.
If you created the original form with adobe, you have the option of distributing the form (file/form distribution..)
to recipients list (could include form creator).
This allows adobe to generate a distribution and form response file and therefore able to track returned forms either as pdf (preferably) or excel/xml converted back to pdf after saving it.
For Point 2 above,assuming your original data set were created using an adobe form you previously saved, open your original form in acrobat pro, go to menu/forms/manage form data/import data (usually as xml). It automatically repopulates the form.
OR
To view returned forms as a set, go to menu/forms/compile returned forms and this will bring up a window that
requires you
-to browse and locate your response file (essentially defining the index form),which is opened into the top row
-then find and add each new completed form into a list in the second row.
You then click ok and all returned forms are opened in a tracker window...
I just realised I am talking about liveCycle ES version8 and this forum refers to pre ES!
I am not sure if this helps but I hope it answers some of your questions.

How to open Word file in APEX, fill it with data from DB and then save it?

Hi everybody!
I haven't enough experience with HTMLDB, I searched for similar thread but didn't find anything, so I decided to write here. I want to open a MS Word document, put some data from a table or report and then close it with saving changes. Could anyone help me to do that, please?
Thanks in advance!

Guys, thanks for being so helpful :-)
I tried this example http://htmldb.oracle.com/pls/otn/f?p=18326:44:::::P44_ID:1682,
but didn't sort out the problem. I downloaded, imported and installed Mail Merge. I readed readme.txt and did everything like it is written, but when I click on "Mail Merge" for emp.rtf, I recieve this in my browser: "You are not authorized to view this page".
By the way, the precedure MAIL_MERGE and the function FIND_RTF_HEADER are valid, cause I changed them according to readme.txt.
Do you have any idea why is this happening and are you sure that Mail Merge works with APEX production version, not only with HTMLDB?

Discoverer Plus Automation- Extract data from Pac2K and fill in Excel 5 min

Hi,
I am new to this tool. I have zero knowledge on this tool.
I got a requirement to fetch the data from Pac2K tool for every 10 mins and export to Excel sheet. This should be done using Discoverer plus. I am using discoverer plus web application.
As it is very difficult to fetch the data manually for every 10 mins, I got a requirement to do the automation.
So, if you would be so kind, could you please let me know possiblity to do the automation for the above process using the Discoverer plus Web Application.
If possible please let me know in detail.

Hi,
Using the Plus it is not possible to automate the export to excel.
This can be done using the desktop edition using a command line.
you can create a batch file and schedule it using any scheduler.

How create report with data from table and some columns results function ?

Hi,
How can i create on apex report region with some columns (of the report) as returned from a table and the other columns as results of plsql functions ?
for example , I want to create a report like that:
device last_date error_msg stop/start
kodak1 06/04/08 null >>
kodak2 08/03/08 good msg --^--
kodak3 08/04/08 err msg >>
3 rows returned
where the 3 first columns are data returned from the table and the forth column is the result of plsql function (returned for example false) and on that i want to display a button of start ( >> in this example ) or stop ( --^-- in this example)

Thomas,
There is no problem here -- this is fully suported scenario.
1. Bind Table dataSource to Customers node.
2. Bind individual cell editors to any attribute of customer or any nested node like Address, say create column with InputField as editor, then for "value" property select Customer.Address.Street.
Your nested nodes (like Address) must be non-singleton, set singleton=false on context designer tab.

Import data from excel file

Hello.
Is anybody can help how to import data from excel file to the form created with designer 7.0. Originally there is a script inside the form to populate drop down list and depending from data selected in the ID number drop down list, there will be filled out the description and the prices text fields. But now I have to modify this form with data from excel file, which has more than 30000 lines and put all this data to script is too much.
So, can somebody know how can I after filling the ID number field , populate the description and price text fields with data from excel file corresponding to this ID number ?
This form is used in Adobe reader.
Any comments are welcome.
Regards,
Aivar

Hi
That's what i said in my prev. Post to clear cache... :)
disable your cache from nqsconfig.ini
In cache section of NQSConfig file,
you find
ENABLE = YES;
set to NO
OR
if you are using data ware house as the source for OBIEE,
you know that when ETL is done, so just create iBot to purge cache automatically at that particular intervals,
So that report runs freshly at that time
And what happened to your View Selector question?

Upload data from excel to crm using BDOC possible or not

Hi all,
I need to upload data from excel to crm(opportunity management) .is it possible using bdoc or not. Please provide the list of methods to upload data from EXCEL and also provide the best method for this scenario .

BDocs are used to transfer data from one SAP system to another like from CRM to ECC or R3.
If u want to upload data from excel to CRM, this can be done with the help of idocs and not bdocs (method 1 - using LSMW).
Take help of a crm technical consultant and define lsmw projects. The project will take care of field mapping and conversion. Once that is done, 4 steps need to be done.
1. Read data
2. Convert data
3. Generate idocs
4. Post idocs
Once the posting of idocs happen error-free, the data will be available in crm system.
Another method will be using transaction SECATT.
Here u can define test scripts and record what all activities are done in a transaction. Then define ur test configs which will contain the excel sheet data and then upload the data.
Reward with points if this helps.

How to read the data from excel file and store into the table?

Hi All,
I have table with BLOB datatype contains a excel file. I have to read that data from excel and store into one table with all the fields in excel.
All the excel fields and my table columns are same.
Can you share with me how can acheive this using LOB's?
Thanks

Hi OraSuirya,
you can try with external tables .
syntax as follows
create table ext_table_csv (
i Number,
n Varchar2(20),
m Varchar2(20)
organization external (
type oracle_loader
default directory ext_dir
access parameters (
records delimited by newline
fields terminated by ','
missing field values are null
location ('file.csv')
reject limit unlimited;
For this you need to create directory
Directory Creation syntax:
create or replace directory ext_dir as 'D:\oracle\user_dir\ext_dir';
grant read, write on directory ext_dir to <User>;
please paste the excel file in the particular directory .
I hope this will help you.
Please correct me if I am wrong anywhere .
Thanks,
Tippu.

Copying data from excel(more than one row) and pasting into table control

I have a requirement to copy data from excel and have it pasted it into the corresponding fields table control when the user clicks on an icon.For the first part I used a class to copy it from the clip board.By the previous process,I get the data inside an internal table, but even after trying to split the data using 'split at cl_abap_char_utilities=>horizontal_tab into table itab.' it's not working.The table and the excel file are of the same structure.
Does anyone know any cause as to why it might not work?Is there any other way to achieve my objective?

please help me ...

please help me ... The question has nothing to do with 'getting' data from excel and certainly not with putting it into MySQL.
The stack trace specifically tells you that your connection string is wrong.
It also tells you which connection string is wrong.
Which you can use to determine specifically which one is wrong. And which you did not provide that info to us.
