Store UTF-8 in Database and Display in JSP(URGENT)

Hi all,
I am developing a software with unicode support, but I am in trouble with it.
The System configuration is:
OS: Windows2000 (English)
Database: Oracle8i 8.1.7.0.1 (NLS_LANG = .UTF8)
Application Server: Bea WebLogic Server 6.1
My problem is:
I have 3 JSP.
The first one is a form for data input.
The second one is validation. It displays the data user filled in first jsp.
The third one is the result. It displays the data user filled in first jsp.
The data will be packed into a value object and this value object will be set to session.
The data of second jsp is got from the value object that is set in session.
The data of third jsp is got from database. The data fetched from database will also be packed into
a value object.
When I input �q��(Big5) in the first JSP, the second JSP will display ��V(Big5),
but the third JSP will be fine, it display �q��(Big5) correctly.
(If the data of second JSP is got from request, the result is same.
You may need to use Big5 Encoding to view this page if the characters do not display correctly.)
The main problem is that if the data is got from database, it will be fine.
But if it is got request or session, the result is incorrect.
I would be appreciate if anyone can help me to solve this problem !
Kammau

If I add "<%@page contentType="text/html;charset=Big5" %>",
I also need to add the following lines in web.xml
<context-param>
<param-name>weblogic.httpd.inputCharset./*</param-name>
<param-value>UTF-8</param-value>
</context-param>
Then, it will be fine in the validate page(It is the second JSP).
However, it will not display correctly in the third JSP that the data is got from database.
Thank you in advance.

 Thanks for your help.
 If I add

 <param-name>weblogic.httpd.inputCharset./*</param-name>
 <param-value>UTF-8</param-value>
 </context-param>
 in web.xml
 I also need to add
 "<%@page contentType="text/html;charset=Big5" %>" in all jsps
 Then, it will be fine in the validate page(It is the second JSP).
 However, it will not display correctly in the third JSP that the data is got from
 database.
 Thanks in advance!

Store Hindi Text in SQLServer and Display in JSP

I've list of users for which I'm preparing objects of User class in which the user name is stored in hindi text.
In the servlet which is storing the values in the database, the code is
User = new User();
user.setName(java.net.URLEncoder.encode(request.getParameter("userName"), "UTF-8"));I've submitted *कैसे हो* It is stored in the database in the following format
*%C3%A0%C2%A4%C2%95%C3%A0%C2%A5%C2%88%C3%A0%C2%A4%C2%B8%C3%A0%C2%A5%C2%87+%C3%A0%C2%A4%C2%B9%C3%A0%C2%A5%C2%8B*
When I get the data from the database and create user object and then stored it in a vector and put it in session.
In the JSP,
user.getName()is displaying
*%C3%A0%C2%A4%C2%95%C3%A0%C2%A5%C2%88%C3%A0%C2%A4%C2%B8%C3%A0%C2%A5%C2%87+%C3%A0%C2%A4%C2%B9%C3%A0%C2%A5%C2%8B*
and
java.net.URLDecoder.decode(user.getName(), "UTF-8")is displaying
à¤à¥à¤¸à¥ à¤¹à¥
I tried using
request.setCharacterEncoding("UTF-8");in the servlet and
<%@page pageEncoding="UTF-8" contentType="text/html; charset=UTF-8" %>in the JSP.
Any suggessions?

hi ravi...
i had also did the same one but not in Hindi it is in Chinese language.before inserting the data into database we need convert hexadecimal code to your hindi string and you store that hex decimal value into database.
when you retrive data from database again u convert this string to general integer format and display it.
observe the below code..
public String settingValue(String call) {
 System.out.println("String Value in setting::\n" + call);
 String chineseName = "";
 StringTokenizer unicodeArray = new StringTokenizer(call, "\\\\u");
 while (unicodeArray.hasMoreTokens()) {
 String s = (String) unicodeArray.nextToken();
 System.out.println("\nValue In setting Value::" + s);
 chineseName += unicodeTochineseCharacter(s);
 return chineseName;
public static String unicodeTochineseCharacter(String unicode) {
 String output = "";
 try {
 System.out.println("\nValue In U2C::" + unicode);
 char i = ' ';
 i = (char) Integer.parseInt(unicode.trim(), 16);
 output = String.valueOf(i);
 System.out.println(" before returning..." + output);
 } catch (Exception e) {
 System.out.println("Exception In Unicode to Chinese::\n" + e);
 return output;
 }let me know weather you need any other details...

Document stores in both SAP database and Content Server

Hi,
We don't want to store doc. in SAP database and chose to use content server. We have KPro checked in configuration also.
Our basis team has created a content repository ZP that points to the content server, in the document area.. they enter "ARCHLINK" instead of DMS. So they told me to create doc. and pick this new ZP to store the doc. But we I created a doc. in CV01N, went to check in the original, the new repository ZP is not on the list of choice to pick from. So I cannot store the doc. in that new content repository.
Our basis team told me that if we use DMS in the document area, the doc. stores in both SAP database and Content Server. We don't want to have doc. stores in SAP database that's why we have content server.
How can I create DMS and store in content server only (not SAP database) ?
Thank you,
Sam Schwartzberg

Hi Samantha,
While check-in activity are you able to choose the new content repository i.e. ZP?
If not then use t-code OAC0 and while creating the repository check whether the certificate is activated by basis or not .
If not then you need to activate the certificate for the new repositoty in CSADMIN then only it will appear in the list while "check-in" the dcouments.
Please check for the same. Also check the t-code OACT , this new repository is shown or not.
I hope this will resolve the query.

Ravindra

Dynamically fetch data from database and display it in the report

Hi,
We have a requirement in developing a report which needs us to dynamically fetch data from the database and display it in the report.
We have a column called WORKER in the report.
For each worker there is a measure(PSA) associated with it.
In the report we have to display both the WORKER and the PSA column.
What we want is, when we display the list of the workers, the corresponding workerid_id of the worker will be passed and the value of his PSA will be fetched from the database and displayed in the report.
Or anything similar to this.
We also have drill applied on this WORKER column. So after any drill up or drill down also the value for PSA should change.
Is there any way of doing this?
Please help if possible.
Thanks,

Creating Bar Charts using Java and Display in jsp

Hi..Is it possible to create a servlet that processes data from database and display the values as Bar Charts in jsp pages. If its possible, is there any examples on how to achieve that?

I don't get it. You already know what needs to be done to solve your problem, the only thing you are missing is the HOW. That's the easy part, if only you break down what you have to know:
1) how do I show an image on a website (this is a basic HTML question actually, not actually related to servlets/JSPs directly)
2) how do I fetch the path from a database (JDBC question) so that I can use this path to link to my image on disc
So what is preventing you from figuring out how to do these two simple tasks? Some clever google searches should give you all the information you need in no time.
by the way: are you sure that you need to store these paths in the database? Is this part of some file upload component?

How to load PDF files into oracle database and display them in APEX

Hi All,
We have a requirement for loading the Loading PDF files (lots of PDf files) to the oracle database and then display the PDF files in the Oracel APEX report.
So that User can view the PDF files. Our current APEX verison is 3.2..
Please let me know how to implement it and where to find the sample application!
Thanks in advanced!
Jane

Thanks Tony for your quick response!
We need to load a lot of PDfs (history + current).
I have a questions about the SQL loader. I am trying to insert a pdf file into a table by following the oracle loading sample:
http://download.oracle.com/docs/cd/B10501_01/text.920/a96518/aload.htm
Example Data File: loader2.dat
This file contains the data to be loaded into each row of the table, articles_formatted.
Each line contains a comma separated list of the fields to be loaded in articles_formatted. The last field of every line names the file to be loaded in to the text column:
Ben Kanobi, plaintext,Kawasaki news article,../sample_docs/kawasaki.txt,
But i don't know to where should I put my pdf file on the server.
for example:
,../sample_docs/kawasaki.txt,
Where is the file 'kawasaki.txt'??
I try my local path, it didn't work. like c:\temp.
then I loaded teh PDf file into our server(/findev20/olmtest/orafin/11.5.7/olmtestcomn/temp) , and In my data file. I put the path
1, pdf_emp1,../findev20/olmtest/orafin/11.5.7/olmtestcomn/temp
but I got the error: the system can not find the file specified.
Where should I put the PDf files on the server and how to specify the path in the data file?
Thanks!

How to sort data from database and display in combobox in required order

Hi evrybody, it makes me sick i need to get data form database and fill combobox in required order (last item added to database - last firstName) actualy i already did that, but i'm useing DefaultComboBoxModel and all records are sorted in alphabetical order. Thanks very much for any help

The items in the JComboBox are displayed in the order in which you add them to the combo box. Use an order by clause in your SQL statement.

I want to reduse size of BLOB and display in jsp

Please help me ,and if is possible than send me code for resize and display BLOB image injsp page

Resizing: check the Java2D API. Tutorial.
Displaying: create a servlet which writes the InputStream from the ResultSet to the OutputStream of the HttpServletResponse. Then call that servlet along an unique parameter in the <img> tag. Example.
Resizing is a fairly expensive task, have you considered resizing it before saving in database? Then you need to do it only once.

Fetching record from table and displaying in JSP while loading page -struts

Hi all,
I have a problem relating to struts .
I am fetching records from database and I want to diaplay those records in corresponding fields in the jsp page.
I am using Struts MVC Framework.
I am giving the sample code below.
In my action class i am giving the following code.
String sql="Select empname from emp where empcode='1' ";
ResultSet rs=S.executeQuery(sql);
if(rs.next()){
EditForm e=new EditForm();
e.setEmpname(rs.getString(1));
In my Action Form
I gave setter and getter methods for Empname
public String getEmpname() {
return empname;
public void setEmpname(String empname) {
this.empname = empname;
In my jsp gave
<html:form method="POST" action="submitForm.do?action=1" >
<html:text property="empname" />
</html:form>
The targets given are correct and it is being redirected.
But the value is not displaying in the textbox while the jsp is loading.
There is a record for the sql query.
Anybody please help me out
It is very urgent
Thank You
Parvathy

Now in the following code, why are u creating a new form?
Why dont you use the form which is input to the Action Class's execute methof?
if(rs.next()){
EditForm e=new EditForm();
e.setEmpname(rs.getString(1));
}Thanks and regards,

How to pass arraylist of object from action class to jsp and display in jsp

I need to do the following using struts
I have input jsp, action class and action form associated to that. In the action class I will generate the sql based on the input from jsp page/action form, create a result set. The result set is stored as java objects in a ArrayList object.
Now I need to pass the arraylist object to another jsp to display. Can I put the ArrayList object in the request object and pass to the success page defined for the action? If this approach is not apprpriate, please let me know correct approach.
if this method is okay, how can I access the objects from arraylist in jsp and display their property in jsp. This java object is a java bean ( getter and setter methods on it).
( need jsp code)
Can I do like this:
<% ArrayList objList = (ArrayList)request.getattribute("lookupdata"): %> in jsp
(***I have done request.setattribute("lookupdata", arraylistobj); in action class. ***)
Assuming the java object has two properties, can I do the following
<% for (iint i=0. i<objList.size;I++){ %>
<td> what should i do here to get the first property of the object </td>
<td> what should i do here to get the first property of the object </td>
<% }
%>
if this approach is not proper, how can I pass the list of objects and parse in jsp?
I am not sure what will be the name of the object. I can find out how many are there but i am not sure I can find out the name
thanks a lot
