Read values from html response

Hi,
I am trying to make a call to an API using UTL_HTTP POST method over SSL and read the response html page and extract the values from the reponse.
I am able to call and get a response back in html format. I have stored the html response in a clob variable.
Now i want to parse this html and extract values from the form input items and send them out through OUT parameters.
For example, from below reponse i want to extract the value '1111d7nhcwse30wq' from 'I4GO_UNIQUEID'
Can anyone help me with the code to parse this html response and extract the values.
Any help is greatly appreciated.
Thanks
Sharath

Reading values from lookup columns through custom workflow in SharePoint 2013

We are able to read the values of text, number columns through custom workflow (via coding) in SharePoint 2013. However, we are not able to read values from lookup columns. So, request anyone to provide help on this.
Thanks & regards,
Aditya

Hi,
According to your post, my understanding is that you want to read values from lookup columns through custom workflow in SharePoint 2013.
Since the workflow just doesn't get lookup fields, let's give it something static to work with instead. If we can capture the ID of the lookup field and store that as a static value in our list, the workflow can happily use that to look up our related.
For more information, you can refer to:
SharePoint 2013 Workflows and Lookup Columns

Questions:
1)- Is posible to read the values of field c?. How?
2)- If is not posible to read the field values, Is posible to transfor the xmlfield to:
Where I will be able to use xmltable columns and loop getting the values.

How to read values from DMM4040

Hi,
I am using DMM4040, NI PXI 6509 device.
I need to make some port pins high which i have already done and now i have to read value captured by DMM then i have to make my port pins low if my value is within limits.
Can u suggest me how to read values from DMM and then by notification i ll make my port pins low.
'' A professional is someone who can do his best work when he doesn't feel like it''...........

What language are you using? If using LabVIEW, you use the NI-DMM API to communicate with the 4040. Just take your reading, do your limit comparison, and set your lines based on the comparison results.

Passing values from HTML to JSP method,

Hello:
I am starting to wonder if what I am doing will ever work...
Ok, I am trying to avoid javascript. I have a drop-down list named "year" and I wish to call a JSP method that is defined/declared in the same JSP.
First, I want to pass the chosen option to the method and then store the name/value in a global variable.
Second, depending on what the user selects, I will get values from an array defined/initialized on page load AND display those values in another drop-down list.
As a test, and until now, I have done this. I am not passing anything yet, I just wanted to test this "fuzzy logic" I am having:
<%!
String currentYear;
private void showDaysInDDList()
currentYear = request.getparameter("year");
%>
Then on the HTML part of the page I have a drop-down list:
<html>
<head>
<title></title>
<link rel="stylesheet" type="text/css" href="style.css">
</head>
<body bgcolor="ffffcc">
<form method="POST" name="form1" action="left.jsp">
<select name="year" onchange="<%=showDaysInDDList()%>">
     <option></option>
     </select>
I am getting the following errors:
An error occurred at line: 105 in the jsp file: /p1/left.jsp
request cannot be resolved
....and regarding to the onchange="<%=showDaysInDDList()%>"> part I am getting the following:
An error occurred at line: 204 in the jsp file: /p1/left.jsp
The method print(boolean) in the type JspWriter is not applicable for the arguments (void)
In the action="left.jsp", left.jsp is the same page where the drop-down list and the method is. I am not sure if that is another error.
I will continue here with my coffee ... any help will be extremely appreciated !!..
I'll have to shut down my "asp.net mind" for a while..
I'll reply later,
MMS

Ok, this is a bit messy here. I don't know how much you've read up on JSP but you seem confused about some fundamentals to me. However, you mention that you've worked with ASP .net so I'm going to assume you do have some notion of how thing should work in general.
1. JSP is on the server-side and events like onchange that you've used take place on the client-side after the JSP/ servlet code has run and produced the HTML page. So calling your showDaysInDDList() will not work.
2. Are you sure you know how the declaration tags ( <%! %> ) work? When you normally write JSP code without these tags, all that code gets compiled into the service method of the corresponding servlet that the JSP gets turned into. But, you can declare your own methods and variables outside the service method by using these tags.
So what you're effectively doing is declaring
private String/ void showDaysInDDList()
}and followed by your usual _jspService()
public void _jspService(HttpServletRequest request,
   HttpServletResponse response)
     throws IOException, ServletException
}Now it may be clear, that the request object is not available in the showDaysInDDList() method by default; you'll either have to declare it ( not sure if it's good programming practice or not ) or pass the required parameters in the call.
3. Like you seem to have realized, that error about the printing of booleans was related to the return type of your method because <%= %> translates to out.println(); and since the argument was the method call, the return value was to be printed which here was a void ( not sure why it says boolean though :D ).
Read up on this introduction to JSPs http://java.sun.com/developer/onlineTraining/JSPIntro/contents.html, seems to be pretty good and covers everything in quick, short chunks.
Hope this helps.

How to read value from Key flexfield added on to the newly created SIT

Hi Experts,
I have a requirrment to display a new structure in the Special Information Types (SIT) screen in SSHR. The data entered into the segment needs to be validated using PL/SQL function.
I have performed below steps to display the structure/field on SIT Page
1. Created new flexfield structure as XX_LEAVE_ENCASHMENT under the "HUMAN RESOURCE" Application (Application id- 800) and flexfield TITLE "Personal Analysis Flexfield" (PEA).
2. Added a new segment "Encash Days" for the newly created flexfiled structure "XX_LEAVE_ENCASHMENT".
3. Added this new structure in the Special Information Types form in HRMS responsibility
4. The structure is enabled on the SIT screen.
Now I want to validate the data entered in Encash Days field in this page by calling a PL/SQL function. This can be done by extending the SIT page Controller.
But how should the ID of the newly enabled segment (in the new Flexfield strucuture) be retrieved in the controller inorder to read the user-entered value (to further call the validation program)? Or is there any other way of achieving this functionality in OAF?
Please help.
Thanks.

Hi,
Yes, u can get the value from the SIT and perform the relevant validation too.

Reading value from bar code reader into JSP

Hi all,
I am designing a web-site which can read the barcode value from the barcode scanner.Please let me know how to do that.
Awaiting Reply.
Thanks
Gowrishankar

1) I don't think there's a <input type="barcode-reader"/> form element in HTML - whether it was generated from a JSP or not doesn't matter.
2) You could use an applet. But only if the user has all necessary means installed to let Java use the barcode reader.
3) The applet needs to be signed, of course.
4) If the user doesn't have the stuff installed, you could theoretically make the applet install it, if it knows where to get the resources and if the access restrictions allow it.
So there's a purely theoretical possibility at best.

Reading Values from Listbox and data source into MS Office Toolkit

Hi,
Been trying to get this to work but making no progress and my lack of experience on labview is becoming a hinderence.
Does anyone know how I can read the values from the listbox example attached into MS Office Toolkit for Excel?
The values from the listbox need to be compared to mulitple values from a strain data source.

Reading values from ServletRequst in Filter

I have a filter that captures some basic info (request method and uri) from request. But whenever I read parameters contained in http request for "POST" method, I can't figure out how to repost parameters to request. I think that after I read parameters from request in filter, parameters aren't available in http servlet. I think that I have to repost parameters to request after i read it.
does anybody know how to do it?

here is the code.
     BufferedReader in = new BufferedReader( new InputStreamReader (request.getInputStream()));
     String line = null;
     while (null != (line = in.readLine()))
          System.out.println(line);
After I use request.getInputStream(), I can't retrieve values from parameters. is there any way to handle this issue?
I'd appreciated for any idea.

Reading values from standard report in custom report dynamically

Hello Gurus,
I have a strange requirement, We have some standard reports which displays output in drop down blocked data. I want to create a custom report which will get that data in my internal tables.
Just to elaborate this requirement, I will give you a example:
I have a standard report which output as first line 'A' and second line as 'B'. Now when I press drop down in 'A', it displays line items say 1,2,3,4,5.... Similarly block 'B' once when pressed displays line items 6,7,8,9,10.
Here I want a custom report which directly read data from this standard report and gives us the values of line items 1,2,3,4,5 in one internal table and similarly items 6,7,8,9,10 in another internal table.
Hope the question clarifies the requirement now.
Request you to please provide the resolution.
Thanks,
Harjeet

Hi Harjeet,
Use sumit statement for standard program and export the list to memory. and then read list from memory and use in your custom program.
Use below code for reference.
DATA: t_list TYPE abaplist OCCURS 0.
SUBMIT rfdopr10
                ************** your options
                AND RETURN
                EXPORTING LIST TO MEMORY.
CALL FUNCTION 'LIST_FROM_MEMORY'
TABLES
    listobject       = t_list
EXCEPTIONS
    NOT_FOUND        = 1
    OTHERS           = 2.

the reason why you can't get the text is because you are reading the value before some actually inserts anything in any fields.
Here is what you need to do:
Create a JDialog/JFrame. Create a JPanel and set that panel as contentPane (dialog.setContentPane(panel)). Insert all the components, ie JLabels and JTextFields. Add two buttons, Login and Cancel to the panel as well. Now get the username and password field values using getText() inside the ActionListener of the Login.
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class LoginDialog extends JDialog
String username, password;
public LoginDialog( ){
    setTitle( "Login" );
    JPanel content = new JPanel(new GridLayout(0, 2) ); // as many rows, but only 2 columns.
    content.add( new JLabel( "User Name" ) );
    final JTextField nameField = new JTextField( "" );
    content.add( nameField );
    content.add( new JLabel( "Password" ) );
    final JTextField passField = new JTextField( "" );
    content.add( passField );
    JButton login = new JButton( "Login" );
    login.addActionListener( new ActionListener(){
      public void actionPerformed( ActionEvent ae ){
        username = nameField.getText();
        password = passField.getText();
        // call a method or write the code to verify the username and login here...
    content.add( login );
    JButton cancel = new JButton( "Cancel" );
    cancel.addActionListener( new ActionListener( ){
      public void actionPerformed( ActionEvent ae ){
        dispose(); // close the window or write any code that you want here.
    content.add( cancel );
    pack( ); // pack everything in the dialog for display.
    show(); // show the dialog.

Reading values from JTable

I have som problems reading the values from JTable. the user enters a number in the table, but some cells are empty. I want to store the values in an int array, and if the user has not filled a cell it is supposed to be set as zero. Now I cant seam to get it right.
I get the error message: Exception in thread "AWT-EventQueue-0" java.lang.NumberFormatException: null
It is for the code. Integer intObj = new Integer(str);[/u
int[] tmp = new int[brettStorelse * brettStorelse];
for (int i = 0; i < brettStorelse; i++) {
     for (int j = 0; j < brettStorelse;j++) {
          String k = String.valueOf(j+i);
          int l = Integer.parseInt(k);
          if (sudokuTabell.getValueAt(i, j) != null) {
               String str = (String) sudokuTabell.getValueAt(i+1, j+1);
               Integer intObj = new Integer(str);
               tmp[l] = intObj.intValue();
               System.out.println(tmp[l]);
          } else {
               tmp[l] = 0;

What are you doing to prevent the user from entering values in the table that are not parseable? Seems like you should be doing the below.
int[] tmp = new int[brettStorelse * brettStorelse];
for (int i = 0; i < brettStorelse; i++) {
     for (int j = 0; j < brettStorelse;j++) {
          String k = String.valueOf(j+i);
          int l = Integer.parseInt(k);
          if (sudokuTabell.getValueAt(i, j) != null) {
               String str = (String) sudokuTabell.getValueAt(i+1, j+1);
                        try {
                            tmp[l] = Integer.parseInt (str);
                        catch (NumberFormatException e){
                             tmp[l] = 0;
               System.out.println(tmp[l]);
          } else {
               tmp[l] = 0;
}
