HI all pls give me diff btwn upload ws_upload and GUI Upload
HI All,
pls give me difference between
upload
ws_upload and
GUI Upload
Thanks & regards .
Bharat KumarHi,
WS_* Function modules are replaced by GUI_* FMs from 4.7 SAP version.
GUI_* modules have additional parameters when compared with WS_* FMs.
Both FM are used for uploading data .
But ws_upload is obsolete now .
WS_UPLOAD and WS_DOWNLOAD, the function modules used until now are not part of the standard set of ABAP commands. They are used to display the file interface on the presentation server. WS_UPLOAD and WS_DOWNLOAD are not compatible with USs and have been replaced by GUI_UPLOAD and GUI_DOWNLOAD.
The new function modules, GUI_UPLOAD and GUI_DOWNLOAD, have an interface that also allows you to write Unicode format to the local hard drive. For a description of these interfaces, refer to the documentation for each function module, available under SAP Easy Access " Development " Function Builder " Goto " Documentation.
WS_UPLOAD, GUI_UPLOAD FMs are used in BDCs.
WS_UPLOAD loads files from the Presentation Server to Internal ABAP Tables.
This is used upto SAP 4.6 version.
GUI_UPLOAD is used to loads a file from the PC to the server. The data can be
transferred in binary or text format. Numbers and data fields can be
interpreted according to the user settings.
You can check this for some info

Hi I am using a ftp class (known as FTPConnection) that i found on this site: http://www.nsftools.com/tips/JavaFtp.htm , and they only have an example of how to download a File through FTP and not upload one. I am in the proccess of making an FTP upload applet, and need some help on getting upload to work. I also need it to work on both a Pc and mac, so that may be attributing to the problem becuase i am currently on a mac which uses file:// instead of C:\\. Ill post the ftp class, and a snippet of my code that tries to upload a selected file.
FTPConnection
/* <!-- in case someone opens this in a browser... --> <pre> */
* File: FTPConnection.java
* Author: Bret Taylor <[email protected]>
* URL: http://www.stanford.edu/~bstaylor/cs/ftpconnection/FTPConnection.java.shtml
* see also <a href="http://www.nsftools.com/tips/JavaFtp.htm">http://www.nsftools.com/tips/JavaFtp.htm</a>
* $Id$
* Parts of this code were adopted from a variety of other FTP classes the
* author has encountered that he was not completely satisfied with. If you
* think more thanks are due to any particular author than is given, please
* let him know. With that caveat, this class can be freely distributed and
* modified as long as Bret Taylor is given credit in the source code comments.
* Modified by Julian Robichaux -- http://www.nsftools.com
* Added constructors, logout(), listFiles(), listSubdirectories(), getAndParseDirList(),
* processFileListCommand(), and overloaded getFullServerReply().
* Also added StringBuffer parameter options to transferData() and executeDataCommand()
* and did a few other little things.
import java.io.*;
import java.net.*;
import java.util.*;
* <p>A wrapper for the network and command protocols needed for the most common
* FTP commands. Standard usage looks something like this:</p>
* <pre> FTPConnection connection = new FTPConnection();
* try {
* if (connection.connect(host)) {
* if (connection.login(username, password)) {
* connection.downloadFile(serverFileName);
* connection.uploadFile(localFileName);
* connection.disconnect();
* } catch (UnknownHostException e) {
* // handle unknown host
* } catch (IOException e) {
* // handle I/O exception
* }</pre>
* <p>Most FTP commands are wrapped by easy-to-use methods, but in case clients
* need more flexibility, you can execute commands directly using the methods
* <a href="#executeCommand(java.lang.String)">executeCommand</a> and
* <a href="#executeDataCommand(java.lang.String,
* java.io.OutputStream)">executeDataCommand</a>,
* the latter of which is used for commands that require an open data port.</p>

Batch Input Recording - GUI Upload Function
Hello,
i want to record a batch input.
Within the recording a Gui Upload Function is called, so that the user have to select a file from the local disk, which should be uploaded into the system. That step wasn't recorded by the bach input recording.
Is there any soluion for that?
Regards,
TomSdAs Suhas said, these kind of UI dialogs cannot be handled by batch input technology.
Sometimes transactions allow the batch input by displaying another kind of UI dialog that is allowed. Try to record using "simulate background mode", maybe the program will display another UI dialog. Make sure also to untick the "no BI mode" checkbox.
But maybe this transaction isn't planned to be used in batch input at all (which transaction do you need to record?). In that case, the only solution is maybe eCATT (with external tool connected as I am aware). -
Help with GUI (calling one class from other class)
Hi everybody,
I am new at GUI and I need your help..
I have a JPanel, named "holdAll", layout of which is set to BorderLayout. I have implemented all other JPanels in different class files. For example, I have TopPanel, LeftPanel, etc. as shown below
LeftPanel myLeft = new LeftPanel();
holdAll.add(myLeft, BorderLayout.WEST);
RightPanel myRight = new RightPanel();
holdAll.add(myRight, BorderLayout.EAST);
TopPanel myTop = new TopPanel();
holdAll.add(myTop, BorderLayout.NORTH);
MiddlePanel myMiddle = new MiddlePanel();
holdAll.add(myMiddle, BorderLayout.CENTER);
BottomPanel myBottom = new BottomPanel();
holdAll.add(myBottom, BorderLayout.SOUTH);
That works well but I have difficulties in ActionListeners.. For example, in my TopPanel class I have the code below:
public void actionPerformed(ActionEvent e) {
if (e.getSource() == btnInsert) {
int returnVal = fc.showOpenDialog(fc);
if (returnVal == JFileChooser.APPROVE_OPTION) {
File file = fc.getSelectedFile();
myImage newImage = new myImage(file);
System.out.println(newImage.myHashCode());
Here, if I have upload new image, then I have to update the listImage in the LeftPanel class.. But, I could not access the lstImage object in the LeftPanel class from the actionListener event in the TopPanel class.
What should I do? Is my design poor?public class TopPanel extends JPanel implements ActionListener { //it doesn't allow "extends JPanel, Observable"
JFileChooser fc;
JButton btnInsert;
JButton btnDelete;
public TopPanel() {
setLayout(new FlowLayout());
setBorder(BorderFactory.createBevelBorder(1, Color.WHITE, Color.GRAY));
btnInsert = new JButton("Insert");
btnDelete = new JButton("Delete");
JLabel myLabel = new JLabel(" Search : ");
JTextField txtSearch = new JTextField();
txtSearch.setColumns(20);
JToolBar searchToolBar = new JToolBar();
fc = new JFileChooser();
btnInsert.addActionListener(this);
searchToolBar.add(btnInsert);
searchToolBar.add(btnDelete);
searchToolBar.add(myLabel);
searchToolBar.add(txtSearch);
add(searchToolBar);
public void actionPerformed(ActionEvent e) {
if (e.getSource() == btnInsert) {
int returnVal = fc.showOpenDialog(fc);
if (returnVal == JFileChooser.APPROVE_OPTION) {
File file = fc.getSelectedFile();
*//Here I want to send fc.GetName() to the JList in the LeftPanel*
my LeftPanel class is below:
public class LeftPanel extends JPanel{
public LeftPanel(){
this.setLayout(new BorderLayout());
setBorder(BorderFactory.createBevelBorder(1, Color.WHITE, Color.GRAY));
JPanel pnlButtons = new JPanel();
JButton btnName = new JButton("Name");
JButton btnSize = new JButton("Size");
JButton btnDate = new JButton("Date");
pnlButtons.add(btnName);
pnlButtons.add(btnSize);
pnlButtons.add(btnDate);
pnlButtons.setBorder(BorderFactory.createLineBorder(Color.BLACK));
JPanel pnlImage = new JPanel();
JList lstImage = new JList();
lstImage.setVisible(true);
pnlImage.add(new JScrollPane(lstImage));
add(pnlButtons, BorderLayout.NORTH);
add(pnlImage, BorderLayout.CENTER);
Is there any simple way? -
Urgent help required for upload of vendors in commpr01
Hi Experts,
In the PRODUCT MASTER(commpr01) under the RELATIONSHIP> VENDOR tab>I need to upload the Vendors(Business partner id, description and product id of business partner) from a flat file.
Is there any BAPI available to load the vendor details..
Please help its urgent..
Thanks in advance,
SundarHi Sudip,
1) create custom controller and appropriate context structure there (dataNode(Name,Phone,ID,Address,Check))
2) create view StartView. Map data node from custom controller to node in view. Create table and bind context node attributes to appropriate table columns.
3) create view ResultView. Map data node from custom controller to node in view. Create 2 nodes (CheckedData, UncheckedData) with supply methods. Create filtering implementation in supply methods (add checked and unchecked node elements to appropriate nodes).
4) create new window with resultView as default view
4) in startView in button action handler put something like
IWDWindowInfo _windowInfo = wdComponentAPI.getComponentInfo().findInWindows("Popup");
IWDWindowManager manager = wdComponentAPI.getWindowManager();
IWDWindow _window = manager.createWindow(_windowInfo, true);
_window.open();
So, just tried localy and it works.

Help please to Upload a file from my PC to server's KM

Help!! uploaded files in the application is not getting applied
Hi all,
I have 2 css file, 1 image file and 3 javascript files uploaded.
once when i clear the browser cache and start the application it works fine.
ie all files are getting applied in the application.
then when the page is refreshed in the middle of the application by clicking a button (ie i have search report, by clicking a button according to the data in the form, report will get displayed).
can any one please help me? I really need to get this work.
Thanks,
Bye
Srikavi.Srikavi,
My point is that if you didn't resolve the problem you were working in the other thread (and getting help from others there and keeping them informed of your progress there) then it's a bad thing to abandon that thread and mislead those who were following it.
I suggest you announce that this thread is a mistake and resume work in the other thread.
That way all the resources will be applied in a central place.

Hi, I am doing a small java project and I am expected to code all the GUI I need in just one class file. Can someone help me? My GUI consists of 2 JButtons, 2 JLabels and 1 JTextField. Also I need to have ActionListener for both of the buttons all in just 1 class file. Anyone please help. It is better if you can provide me with some sample coding to view
That sounds like a very arbitrarily cooked-up requirement. Homework?
Assuming your class needs to be a component itself, simply add the buttons, labels and fields into it, typically within the constructor.
If you mean "one source file" then I would advise using an inner class as your ActionListener; you may even want two. You may like to use anonymous classes which, for instance, call methods in your outer class. All of these solutions will produce more than one class file from the single source file.
If you really do mean "one class file" then you will need your outer class to implement ActionListener and determine from the getActionCommand() or getSource() methods which of the two buttons the event emanated from. It's a less clean way of going about it, but you get your single class file.
No sample code - if you need further explanation of the above then just Google for the underlined terms. -
Can anyone please help me in finding out the meaning of the field values of second APDU
What I try to say is how the value " C4 82 03 81" is calculated. I am able to figure out rest of the values of the upload command.
cm> upload -b 250 "C:\....\app\javacard\app.cap"
=> 80 E6 02 00 13 06 73 4D 41 74 ...00 03 00 00 00 00 00 00 00 .........
(1769 usec)
<= 00 90 00 ...
Status: No Error
=> 80 E8 00 00 FA C4 82 03 81
And if any one knows how the enc of the message takes place. Using SCP -02 i am able to generate CMAC but encryption of data not.The JCShell upload command includes two consecutive GlobalPlatform APDU commands: INSTALL [for load] and following multiple LOAD commands. It shall be seen as a fixed sequence. The LOAD command contains parts of the CAP file. The component order is defined in the Java Card Virtual Machine Specification, as well as the CAP structure itself. So what you see in the second command is the LOAD command, and the first component to be loaded (see JCVM 2.2.1/2).
Encryption according to SCP02 (C_ENC + C_MAC) is specified in eg GP2.1.1, Appendix E SCP02. You will find there the algorithm. -
HELP! File Upload Servlet and Internet Explorer
Hello people. I hope this is an easy problem to solve...
I have a servlet upload program that works using Mozilla browser (www.mozilla.org), but for some reason it doesn't work using Microsoft IE. The servlet is also using the servlet upload API from Apache (commons).
I'm using IE version 6.0.2800.1106 in a Win98SE host computer. I get a cannot find path specified error message (see below). At work, I also get the same error message using IE, but don't know what version. The OS is XP. Unfortunately, at work, I can't install Mozilla browser (or any software-company policy) to see if Mozilla works there too. I would've like to have tested to see if the upload program worked on Mozilla on a truly remote computer.
So I figured, it must be a IE configuration issue, but darn it!! I began by resetting IE to default settings, but still have the problem, I played around with several different combinations of settings in "Tools"-->"Internet Options...", and I still get the error message. Someone PLEASE HELP ME!!!
Dunno, if it will help, I've also pasted the upload servlet source code below and the html file that's calling the upload servlet, but you still need the Apache commons file upload API.
Trust me on this one folks, for some reason it works for Mozilla, but not for IE. With IE, I can at least access web server, and therefore, the html file that calls the upload servlet , so I don't think it's a Tomcat configuration issue (version 5.0). I actually got the code for the file upload servlet from a book relatively new in the market (printed in 2003), and it didn't mention any limitations as far as what browser to use or any browser configuration requirements. I have e-mailed the authors, but they probably get a ton of e-mails...
Anyone suggestions?
Meanwhile, I will try to install other free browsers and see if the file upload program works for them too.

-DanI'm guessing what is happening is that Mozilla tells the servlet "here comes the file myfile.zip". The servlet builds a file name for it:
String path = sc.getRealPath("/files");
// path is now C:\TOMCAT\webapps\MyWebApps\files\
fi.write(new File(path, fi.getName()));
// append myfile.zip to "path", making it C:\TOMCAT\webapps\MyWebApps\files\myfile.zipIE, however, tells "here comes the file C:\WINDOWS\Desktop\myfile.zip". Now imagine what the path+filename ends up being...
So what you want to do is something along the lines of (assuming Windoze):
public static String basename(String filename)
int slash = filename.lastIndexOf("\\");
if (slash != -1)
filename = filename.substring(slash + 1);
// I think Windows doesn't like /'s either
int slash = filename.lastIndexOf("/");
if (slash != -1)
filename = filename.substring(slash + 1);
// In case the name is C:foo.txt
int slash = filename.lastIndexOf(":");
if (slash != -1)
filename = filename.substring(slash + 1);
return filename;
fi.write(new File(path, basename(fi.getName()));
....You can make the file name check more bomb proof if security is an issue. Long file names trying to overflow something in the OS, NUL characters, Unicode, forbidden names in Windos (con, nul, ...), missing file name, ...
