How to get the alias name of an attribute of a VO from its column name?

How can I programmatically get the alias name of an attribute of a VO given its column name?
Often alias and column names are not same when the VO is created (and I don't require them to be the same)

Hello John.
I will be more precise. When the VO based on a table comes out from the wizard, it produces xml entries like the following one:
<ViewAttribute
Name="ColumnName"
AliasName="COLUMN_NAME"/>There the column of the table on the DB really is COLUMN_NAME. The wizard mangles that name producing ColumnName as Name property.
This is ok. I don't want to change this default behaviour.
What I need is to programmatically get the value of that attribute given its AliasName property value:
String f(ViewObject vo, String AliasName) {
return (String)vo.getCurrentRow().getAttributeFromAliasName(aliasName); // getAttributeFromAliasName does not exist
// instead of return (String)vo.getCurrentRow().getAttribute(Name);
That is, usually getAttribute expects what in the xml is the Name property. However, I want a sort of getAttribute() expecting the AliasName.
I hope it's clear.

10.4.11 is as far as you can go with Tiger. You have to pay for the next update. It is not available via Software Update. Depending on which Mac you have, it can be Leopard, Snow Leopard, or Lion.

How to get the vaue of HTML Id attribute.

Hi Friends,
Is it possible to fetch the value of an Id attribute of the HTML using jsp.Say, here I am pasting a code for populating the dropdown and each option is assigned an id like this //Populating the drop down with details
// id will have the identifier requirded to identify the production.
out.println("<option id=\""+D_Production.curProductionID()+"\">"+D_Production.curProduction()+"</option>"); So is it possible to get the value assigned to ID using JSP.
Thanks,
Zach.

Use value attribute of <option> tag instead. It specifies the value to be sent to a server when a form is submitted

How to get the menu bar back after turned off all toolbars from the "View" menu

Do this: turn OFF all toolbar view from the view menu, with the Menu toolbar the last one.
Problem: cannot find any UI to turn it back, stuck with a bare window, except the tab list.
== This happened ==
Every time Firefox opened
== turn OFF all toolbar view from the view menu, with the Menu toolbar the last one.

Press the Alt key, this temporarily brings up the menu bar. You an then use the View menu to re-select the menu bar.

How to get the Empty page in Webi report

Hi,
I have to insert the charts in the report but i don't have the space to insert the charts in same page so i need one more page how to get the blank page in report
thanks,

turn your report from Page Layout to Draft Mode. Than you will be able to insert chart in it.
You can view Web Intelligence reports in different modes depending on how you want to work with data and how you want the data to appear.
1. In Web Intelligence Interactive, select the report tab of the report you want to view.
2. Click the arrow next to the View button on the main toolbar above the report.
3. Select the viewing mode.
4. In the Java Report Panel or Web Intelligence Rich Client, use Switch Page/Quick Display on the Reporting toolbar to alternate between Page mode and Quick Display mode.

How to get the complete Stack-Trace ?

Hi,
I'm getting the following error on the screen.
oracle.jbo.DMLException: JBO-26041: Failed to post data to database during "Insert": SQL Statement " INSERT INTO OTA.OTA_QUESTIONS(QUESTION_ID,TEXT,ALLOW_HTML_FLAG,OBJECT_VERSION_NUMBER,BUSINESS_GROUP_ID,START_DATE_ACTIVE) VALUES (:1,:2,:3,:4,:5,:6)".
I want to get the complete stack-trace. I turned on the screen log, but still not getting the error-stack. Can anyone lemme know, how to get the complete error-stack ? This error is raised from a seeded page.
Thanks,
Guna.

This is a developer raised exception and not a standard expection(depends on a profile), that is why you cannot see the error stack.You have to put system.out.println, to debug.You get such errors when there is some fundamental mistake and not framework exception.
As the error says look into the query and see all bind variables are setting properly.

Hi Expert,
I found that we can use Interface INavigationHelperService to read Portal Role selected by user at runtime from http://scn.sap.com/thread/52194
But this class is available in SAP NetWeaver 7.30 Enterprise Portal .
But in SAP NetWeaver 7.0 Enterprise Portal that interface is not available.
INavigationService is available there.
But didn't get any proper discussion on this interface for the same requirement.
Can you please help me.

How to get the current schema name

Hi,
Can anybody please tell me how to get the current schema name, there is some inbuilt function for this,but i am not getting that. Please help me.
Thanks
Jogesh

ok folks, I found the answer at Tom's as usual.
http://asktom.oracle.com/tkyte/who_called_me/index.html
I rewrote it into a function for kicks. just pass the results of DBMS_UTILITY.FORMAT_CALL_STACK to this function and you will get back the owner of the code making the call as well some extra goodies like the name of the code and the type of code depending on the parameter. This ignores the AUTHID CURRENT_USER issues which muddles the schemaid. Quick question, does the average user always have access to DBMS_UTILITY.FORMAT_CALL_STACK or does this get locked down on some systems?

How to get the pull path name from a file upload window

Hello everyone!
I have encountered the following problem with the following JSP code:
<form method="post" action="filename.jsp">
Upload JAVA program:
<input type=file size=20 name="fname" accept="java">
<input type=submit value="go">
</form>
<%
String s = "";
if (request.getParameter("fname") != null)
s = request.getParameter("fname")
%>
The value of s is alway the filename. However I want to get the full path in addition to the filename, so that I can read the file. Does anyone know how to get the pull name of the file?
thanks a lot in advance,

Dear Sir,
thanks a lot for your reply. Please let me explain what I intended to do: I want to upload a file from the local machine and then read the content of the file. Therefore I need to the fullpath of the filename like /var/local/file.java instead of file.java. The latter is what I got.
The problem I have with your code is that the function like "request.getServerScheme()" is not recognized. Maybe is it because I didn't install servelet package? I only installed javax package btw. Also my application runns on Tomcat server if this could give you some information. The error message I had is as follows:

How to get the full path instead of just the file name, in �FileChooser� ?

In the FileChooserDemo example :
In the statement : log.append("Saving: " + file.getName() + "." + newline);
�file.getName()� returns the �file name�.
My question is : How to get the full path instead of just the file name,
e.g. C:/xdirectory/ydirectory/abc.gif instead of just abc.gif
import java.io.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.filechooser.*;
public class FileChooserDemo extends JFrame {
static private final String newline = "\n";
public FileChooserDemo() {
super("FileChooserDemo");
//Create the log first, because the action listeners
//need to refer to it.
final JTextArea log = new JTextArea(5,20);
log.setMargin(new Insets(5,5,5,5));
log.setEditable(false);
JScrollPane logScrollPane = new JScrollPane(log);
//Create a file chooser
final JFileChooser fc = new JFileChooser();
//Create the open button
ImageIcon openIcon = new ImageIcon("images/open.gif");
JButton openButton = new JButton("Open a File...", openIcon);
openButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
int returnVal = fc.showOpenDialog(FileChooserDemo.this);
if (returnVal == JFileChooser.APPROVE_OPTION) {
File file = fc.getSelectedFile();
//this is where a real application would open the file.

buttonPanel.add(saveButton);
//Explicitly set the focus sequence.
openButton.setNextFocusableComponent(saveButton);
saveButton.setNextFocusableComponent(openButton);

simply use file.getPath()
That should do it!Thank you !
It takes care of the problem !!

How to get the name of the current tab.

Hi Experts,
I have two tabs in my tab strip and a button common to both the tabs.Can you please let me know how to get the name of the current tab in the event method of the push button.
Thanks in advance.
Regards,
Arun

1.Declare an Action for OnSelect event of Tabstrip. This event is triggered whenever any change in tab occurs.
2. Declare an Import Parameter in this method
   Tab type String.
3. This parameter has value of the selected TAB.
4. You can set this value in some Attribute in Attribute Tab in this event only (OnSelect):
     wd_this->Att = Tab.
Att is the attribute created by you in Attributes Tab of View. ( of type String)
5. Now the selected Tab ID is stored in this Attribute Att.
6. In the Onaction of Button , retrieve the selected tab value from this attribute using :
           Data : lv type string.
            lv = wd_this->Att
Now lv has your selected TAB ID.
I hope it would help you.
