I'm not convince that the null pointer exception is coming from the database. Rather, whatever you wrote to package the result might be at fault. Regardless, typically, to avoid the web container swallowing an exception is to catch it yourself. Your database call will need to catch the exception and repackage it for the JSP. A bad style would be to use scriptlet and catch the exception, but it could be useful for debugging.

How to display Japanese Text in web page?

Hi,
I am trying to get this i18n stuff right for a few days but don't seem to find all answers.
I am using Sybase databse to store Japanese characters. A perl script inserts the chars in table. Then I use a test JSP program to display the chars.
<%@ page contentType="text/html; charset=UTF-8" %>
<%@ page language="java" %>
<%@ page import="java.io.*" %>
<%@ page import="java.sql.*" %>
<%@ page import="java.util.*" %>
<%@ page import="javax.sql.*" %>
<%@ page import="javax.servlet.*" %>
<%@ page import="javax.servlet.http.*" %>
<%@ page import="javax.naming.InitialContext" %>
<%@ page import="java.text.SimpleDateFormat" %>
<html>
<head><title>testing for utf string</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
<%
Connection conn = null;
Statement stmt = null;
ResultSet rs = null;
try{
        InitialContext context = new InitialContext();
        DataSource ds = (DataSource) context.lookup(System.getProperty("TESTDS"));
        conn = ds.getConnection();
        stmt = conn.createStatement();
        rs = stmt.executeQuery("select comment from TestTable");
        while(rs.next()){
                out.println("<br>");
                out.println("the comment is : <Textarea Cols=\"90\" Rows=\"5\" Name=\"Comment\">"+rs.getString(1)+"</Textarea>");
                out.println("<br>");
                out.println("the comment is "+rs.getString(1));
}catch(Exception e){
        e.printStackTrace();
}finally{
        try{
        if(rs != null) {rs.close();}
        if(stmt != null) {stmt.close();}
        if(conn != null) {conn.close();}
        }catch(Exception e){}
%>
</body>
</html>But the page does not display correctly. If I change the charset as JIS, then it seems to work. But my web page will be having chars from multiple language and I think utf-8 is the right charset for that.
Any pointers?
Thanks

What JSP/Servlet server are you using and what version?
Try this just for debugging:
Remove the rs.getString(1) from the out.println() call. Just assign the returned value to a local String variable and display the variable using (I hope I'm remembering correctly) this:
<%= myVariable %>
I'm curious whether directly inserting the text into the page is somehow different from sending it via out.println.

Help in retrieveing Blob from Oracle db and display it on a web page

I am using Sun Studio creator2 and this is what I want to achieve:
When I click on "Load" button, the image is displayed on the web page(the application is a web application)
I have dropped the "image" object from the pallette
Having the database image displayed in the image field, when I enter the image ?Id? and click on the ?Load? button.
Here is my piece of code:
public String loadButton_action() {
HttpServletRequest request = null;
HttpServletResponse response = null;
String connectionURL = "jdbc:oracle:thin:@//localhost:1521/cdecentre1";;
/*declare a resultSet that works as a table resulted by execute a specified
sql query. */
ResultSet rs = null;
// Declare statement.
PreparedStatement psmnt = null;
// declare InputStream object to store binary stream of given image.
InputStream sImage;
Connection connection = null;
String driverName = "oracle.jdbc.driver.OracleDriver";
String dbName = "cdecentre1";
String userName = "christian";
String password = "cc";
String theid = (String)idField.getValue(); //reading the image id
try{
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
connection = DriverManager.getConnection(connectionURL, userName, password);
/* prepareStatement() is used for create statement object that is
used for sending sql statements to the specified database. */
psmnt = connection.prepareStatement("SELECT image FROM CHRISTIAN.PICTURES WHERE id = ?");
psmnt.setString(1, theid);
rs = psmnt.executeQuery();
if(rs.next()) {
byte[] bytearray = new byte[1048576];
int size=0;
sImage = rs.getBinaryStream(1);
//response.reset();
response.setContentType("image/jpeg");
while((size=sImage.read(bytearray))!= -1 ){
response.getOutputStream().write(bytearray,0,size);
rs.close();
psmnt.close();
connection.close(); } }
} catch(Exception ex){
System.out.println("error :"+ex);
return null; }
At the moment, when I click on the ?Load? button, the image is not present in the image field.
I am only obtaining a message inside the message component.
What should I do to have the image displayed in on the web page?
Your help will be highly appreciated.

How to display all data on one page in web app

Hello.
So I have web app JSF (IceFaces framework) + JBoss all Crystal Report working perfectly. So I have page with Crystal Report tags (e.g.
<bocrv:reportPageViewer reportSource="#{crystalReport.reportPath}" ...
in this report I have table with some data (data from DB) and I want to display this data on one page. Unfortunately now this data are moving to the next page and unfortunately I even donu2019t know how switch to the next page (I see only info e.g. 1with 2).
So how to display this data on one page if its impossible how to torn on pagination.

So I canu2019t do this, I canu2019t display all data on one page (until Iu2019m using JSF tags)?
In JSF tags Iu2019m setting only path to file. In my bean Iu2019m using u201CReportClientDocumentu201D object itu2019s easy way to load report file (u201Copenu201D method) and set parameters (u201CgetDataDefController().getParameterFieldController()u201D method) and also connect to data base (u201Clogonu201D method) but I havenu2019t this property u201CsetSeparatePages(boolean)u201D.
Maybe Iu2019m doing this wrong and there is a simpler way maybe I can use somehow u201CCrystalReportVieweru201D please give my any advice.

Oracle CODE Submission Web Page - MAKE IT WORK finally ( not temporary! )

Is it possible to finally FIX Oracle Code Submission web page. Last year ( last half ) it return errors, same this time. Is any possible way to finally FIX it without anytime alert that it is not working or broken. As far as I understand that the place were we share our code/tips/ideas, not publish our friends or something like that. I think if we use it, then at least put warning prior than we try to submit. No conversations about re-type same code ( tip used SQL, new tip - SAME but using PL/SQL function ), but at least make it work.
Thanks/Ilya

Thanks, Olivier. That may help me in future and shows me where I can edit some of the HTML code (though I've no experience yet of even reading HTML or Javascript, let alone editing it!).
The web page I'm trying to edit has a URL of https://....../sap/bc/gui/sap/its/bbpstart which fits your example but the templates under service BBPSTART seem to bear no resemblance to the screen I need. The code under services BBPSC01 and BBPSC02 looks more relevant but still doesn't refer to the screen input field that I'm looking to edit.
Doing View Source on the web-page dumps the (very lengthy) generated code. Extracted from the header of that code-dump is...
This page was created by the SAP Integrated ITS, WebAS: SRA, workprocess: 0
Template: bbpsc02/99/saplbbp_sc_ui_its_2000.html
Does that point me to the actual editable source?
(I am using SE80 in the SRA system.)
I wrote the above on 3rd Jan but was unable to post it.
Since then I have found template SAPLBBP_SC_UI_ITS 2000 in service BBPSC01 does bear a resemblance to the displayed page code but as a scanty framework. The generated code has vastly more lines. I can't yet see how the template becomes the web page and where all the addditional lines of code come from and are edited.

I keep getting an intermittent error on web pages where a blue box with a question mark appears instead of pictures. For example Facebook and Zappos would load normally on one visit, but if I visit other websites and return I get the blue box.

I keep getting an intermittent error on web pages where a blue box with a question mark appears instead of pictures. For example Facebook and Zappos would load normally on one visit, but if I visit other websites and return I get the blue box instead of pictures. If I restart the problem will go away temporarly. However, normally returnes in time.

HI,
From the Safari Menu Bar click Safari/Preferences then select the Appearance tab. Tick the box next to: Display images when the page opens.
If that box is already ticked, from the Safari Menu Bar, click Safari / Empty Cache. When you are done with that...
From the Safari Menu Bar, click Safari / Reset Safari. Select the top 5 buttons and click Reset. Relaunch Safari. If you still have problems loading images, go here for trouble shooting 3rd party plugins or input managers which might be causing the problem. Safari: Add-ons may cause Safari to unexpectedly quit or have performance issues
Web pages now include a small icon or 'favicon' which is visible in the address bar and next to bookmarks. These icons take up disk space and slow Safari down. It is possible to erase the icons from your computer and start fresh. *To delete Safari's icon cache using the Finder, open your user folder, navigate to ~/Library/Safari/ and move this file "webpageIcons.db to the Trash.*
Make sure Safari is not running in Rosetta. Right or control click the Safari icon in your Applications folder then click Get Info. In the Get Info window click the black disclosure triangle so it faces down. Where you see Open using Rosetta... make sure that is NOT selected.
If you still have problems, go to the Safari Menu Bar, click Safari/Preferences. Make note of all the preferences under each tab. Quit Safari. Now go to ~/Library/Preferences and move this file com.apple.safari.plist to the Desktop. Relaunch Safari. If it's a successful launch, then that .plist file needs to be moved to the Trash.

How can I delete an old web page ??

How can I delete an old web page ?? I have created a web page some time ago and now I want to delete it but i do not know how to do it: can anyone help me ?

Delete the web page where it is published.
If it is published to MobileMe, then you need to log into MobileMe and go to your iDisk or mount it on your desktop and then delete it from your Web/sites folder.
If you have published to a server, then you'll need to download Cyberduck, Filezilla or Transmit - all dedicated ftp programmes to connect with your host/server and then delete your old files from the server.
It really is not hard.

How to display an error message after validation in Formatted Search?

Hi SBO experts,
if an error is detected on validation in a Formatted Search, how to display an error message to the user entering the data?
Thanks & Regards,
Raghu Iyer

i created a formatted search query & attached it to the field 'Quantity' at Line Item level in Sales Order screen. just for testing purpose, i eneterd the following code lines in the query validating 'Quantity'
if $[$38.11.0] > 50
begin
select @error = 1
select @error_message = 'Vendor code cannot begin to X sign.'
end
the system throws the error : Internal error (8180) occurred [Message 131-183]
actually, i need to display an error message to the user if Quantity is not in multiples of the OITM.SalFactor2
if $[$38.11.0] % (SELECT T0.[SalFactor2] FROM OITM T0 WHERE T0.[ItemCode] = $[$38.1.0]) > 0
begin
select @error = 1
select @error_message = 'Error in Quantity.'
end
but, this expression to get the remainder itself seems to have some error
$[$38.11.0] % (SELECT T0.[SalFactor2] FROM OITM T0 WHERE T0.[ItemCode] = $[$38.1.0])
i guess, % operator is used for modulo (to find the remainder of one number divided by another.) ? am i right ?

How do i Hyperlink to a web page from a java application using internet explorer as my default web browser?

It's very simple.You can start any Application with the class Runtime. The command is an array consisting of the path of .exe and the file to be open.
String [] cmd={path of IE+Filename.exe,"URL of your website"}
try
Runtime.getRuntime().exec(cmd);
catch (Exception e)
System.err.println(e.toString());

THis question concerns Safari.

How to display duplicate key in web report?

Hi Experts,
Can anybody tell me how to display duplicate key in web report?
I know in the Bex analyzer, we can allow the duplicate key to be dispalyed via the 'query property' by right click, and in the 'display option' tab, there is an option which named 'forbid duplicate key', if we don't select this option, the duplicate key will be dispalyed in the report result in BEx analyzer.
But how can I do this in Web report? Thanks in advance.
Eileen
