Problems with Unicode webapplication

Hi,
I am developping a small webapplication which is supposed to support Unicode (different characters such as �S�\ etc.).
I have a simple form which calls a JSP page.
The JSP page prints the recieved parameter and prints it to the WEB browser.
The JSP page also prints the parameter to a file.
If I use:
     String textIn= request.getParameter("unicodeText");
     byte d[]=new byte[textIn.length()];
     textIn.getBytes(0, textIn.length(), d, 0);
     String unicodeText = (new String(d,"UTF-8"));Everything works fine but if I use:
     byte[] bytes = request.getParameter("unicodeText").getBytes();
     String unicodeText= new String(bytes, "UTF-8");OR:
     byte[] bytes = request.getParameter("unicodeText").getBytes("UTF-8");
     String unicodeText= new String(bytes, "UTF-8");OR:
     byte[] bytes = request.getParameter("unicodeText").getBytes("UTF-8");
     String unicodeText= new String(bytes);The parameter retrieved by the JSP page contains strange characters (such as a box followed by a questionmark) when I submit for example '�\' and '�S'.
The problem is that the method:
getBytes(0, textIn.length(), d, 0);used in the working example is Deprecated. In the API documentation I am told that the getBytes()
Deprecated. This method does not properly convert characters into bytes. As of JDK 1.1, the preferred way to do this is via the the getBytes() method, which uses the platform's default charset.
I really do not know why I can not get it to work!
/Fredrik

Ha again,
I installed resin and started it with the default
configuration and changed my jsp file as follows:
byte[] bytes =
request.getParameter("unicodeText").getBytes("UTF-8");
String unicodeText= new String(bytes, "UTF-8");
What you are doing is unnecessary (but should still work). Instead, simply write:
String unicodeText = request.getParameter("unicodeText");as the unicode string has already been decoded by the jsp container.
and this gives the wanted result (i.e. it works).
I have tried around 20 chineese characters and �
� and �.
There is only one small thing... all combinations of
� � and � works except
�� in this order.Really? I have tried the same character sequence (with your above code, and with my simplified version) and both work. Here is my test page:
<%@ page contentType="text/html; charset=UTF-8" %>
<%@ page session="false" %>
<html>
<head>
<title>Test encodings</title>
<meta http-equiv="content-type" content="text/html; charset=utf-8">
</head>
<br />
<br />
Request parameters:<br />
<%
   java.util.Map params = request.getParameterMap();
   for (java.util.Iterator i = params.keySet().iterator(); i.hasNext(); ) {
     String param = (String) i.next();
     String[] values = request.getParameterValues(param);
     out.write("<b>" + param + "=[</b>");
     for (int j = 0; j < values.length; j++) {
       if (j > 0) {
         out.write("<b>,</b>");
       out.write(values[j]);
     out.write("<b>]</b> ");
%>
<body bgcolor="#ffffff" text="#000000"
link="#006699" vlink="#006699" alink="#006699" leftmargin="0" topmargin="0"
marginheight="0" marginwidth="0">
<table border="0" align="left">
   <tr><th colspan="2">Enter some values</th></tr>
   <form method="post"
    action="testenc2.jsp"
    <%-- enctype="multipart/form-data" --%>
    >
    <input type="hidden" name="hidden" value="hidden_val" />
    <tr>
     <td>name</td>
     <td>
      <input type="text" name="name" size="50" maxlength="100"/></td>
    </tr>
    <tr>
     <td>address</td>
     <td>
      <input type="text" name="address" size="15" maxlength="20"/>
     </td>
    </tr>
    <tr>
     <td colspan="2">
     <input type="submit" name="cmd" value="send" />
     <input type="submit" name="cmd" value="cancel" />
     </td>
    </tr>
   </form>
</table>
</body>
</html>>
Anyway, this is a minor problem.
Now I have to figure out why it works with resin but
nor with jakarta.tomcat....Doesn't tomcat have a mailing list? That's probably a good place to ask or search.

Problem with unicode in MIME text/html

Hi;
I have a java program that sends email by sending it to our exchange server using SMTP. The email has both a To and a Bcc in the single email sent.
The bcc addressee receives the email fine.
The to address however has a problem with chars that are > 0x7f in the html. The html uses utf-8. But the displayed characters look as though the utf-8 part was ignored.
Also weird, if I go to view, options in Outlook for the bcc email (which is good) it shows:
MIME-Version: 1.0
Content-Type: multipart/alternative;
boundary="----=_Part_0_32437168.1135634913407"

------=_Part_0_32437168.1135634913407--
But for the to email (which has the problem), it only shows:

Content-Type: multipart/alternative;
boundary="----=_Part_0_32437168.1135634913407"

Does javamail do anything weird when it gets an email with a to and a bcc and split it up wrong? I just download and installed the latest mail.jar and activation.jar.
thanks - dave

OK...this didnt quite cure it for me...but having done this AND then this...
MimeBodyPart htmlText = new MimeBodyPart();
final String htmlStuff = "<?xml version=\"1.0\" encoding=\"utf-8\"?>"
+ "<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Strict//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd\">"
+ "<html xmlns=\"http://www.w3.org/1999/xhtml\" xml:lang=\"en\" lang=\"en\">"
+ "<head>"
+ "<title>Stuff.</title>"
+ "<meta http-equiv=\"Content-Type\" content=\"application/xhtml+xml; charset=utf-8\"/>"
+ "</head><body>"
+ "<p>Currency Symbols: \u00A3\u00A2\u20A3\u20AC$<p>"
+ "</body></html>";
DataSource htmlSource = new DataSource()
private String stuff = htmlStuff;
private Charset cset = Charset.forName("utf-8");
public String getContentType() { return "text/html"; };
public java.io.InputStream getInputStream() throws IOException
return new ByteArrayInputStream(cset.encode(stuff).array());
public String getName()
return null;
public OutputStream getOutputStream() throws IOException
throw new IOException();
htmlText.setDataHandler(new DataHandler(htmlSource));
htmlText.addHeader("Content-Transfer-Encoding","base64");
This works for me as shown by the Unicode chars in the html.
If you intend to take this to production create a decent external DataHandler class and avoid the use of the anonymous class - which then avoids the need for the final String and the string can come from anywhere then.
Hope this helps,

MaxDB upgrade/heterogeneus system copy problem with unicode conversion

Project goal:
upgrade a Content Server Version 7.3.0.35 32bit Non Unicode to
version 7.6.06.16 64bit Unicode
I found and followed note 962019
My plan (following the note):
-create a clone of the original Content Server (vmware clone)
-as per note 962019 patched server 7.3.0.35 to 7.3.0.62 (> 7.3.0.57)
-created index
-on a fresh installed windows 2003 server 64bit i installed Content Server with build 7.6.06.16
-using loadercli from the target server (7.6.06.16) exported data
Now i was ready to start the import, as the note states:
"if the database parameter _UNICODE is set to the value NO and you want to start the target system with SAP MaxDB Version 7.6, you can use procedure described here for the import into a target system only with SAP MaxDB Version 7.6.05 build 11 or higher"
Having version 7.6.06.16 i was confident on such procedure, but my import stops immediatly with error:
D:\exportKpro>loadercli -d PRD -u SAPR3,SAP -b import.sql
Loader protocol: 'C:\Documents and Settings\administrator\My Documents
\sdb\loader\log\loader.log'
Loader packages: 'C:\Documents and Settings\administrator\My Documents
\sdb\loader\packages'
Error connecting user SAPR3 to database PRD on local host: -25005
User (SAPR3) logon to database PRD failed: SQL error -8046 = Conversion from UNI
CODE impossible: 7600 (error position: 1)
And now i'm stuck with no hints on how to proceed.
Thanks in advance.

Hello Simone,
as you're staying on Windows platform, there is no need for a heterogenous system copy.
All you've to do is to upgrade the 32-Bit installation to your target release (why not use MaxDB 7.7 right away?).
Once this is done, you can check whether the database catalog is still non-unicode (_UNICODE=FALSE).
If it is, there is a catalog migration procedure you can use to change this.
If the 32-Bit database is as you want it, take a full data backup.
Then uninstall the 32-Bit software, install the same version of MaxDB in the 64-Bit fashion.
Finally create the db instance by a restore of the backup.
After a load_systab your database is fully ready to go!
Just to stress this again: the _UNICODE parameter is not about your data!.
It's about the database catalog.
Having this parameter set to YES you can create e.g. tables named with Unicode characters.
The parameter does in no way affect your business data!
Since many customers ask why they should't use loadercli for a scenario like this:
a) It's only supported if you must use it, that is, you change the byte-order of the OS platform
b) it's way faster than export and import. We're talking about a few hours compared to days here!
c) It's much safer and controllable to use backup/restore and SDBUPD and move on step-by-step than exporting all data into a big file chunk and hoping that everything will be fine afterwards.

Lars

Problems with Unicode in extending JCo with JNI/librfc

Hello,
Problem:
We are using JCo for communication with a SAP-System. We have an extension written in C using JNI for handling callbacks. Let's call it cb.dll.
This extension is not unicode enabled. Now we have to connect to an unicode SAP-System. We do it with JCo, so the connection is in unicode mode. The result is, that our cb.dll does not work.
If you want to enable the dll to handle unicode, the last step beside reengineering the C-code, is to link it against the librfc32u.dll.
But then the communication in the cb.dll with SAP does not work, because the initial connection was made with JCo an JCo is using librfc32.dll. The cb.dll uses the RFC-handle from JCo.
Question:
How communicates JCo with a unicode SAP-System using librfc32 (non unicode) ?
How can I use this method for our own dll ?
thanks in advance

FONT problems with UNICODE - URGENT

i'm trying to present text in different languages, like english, greek or cyrillic and so on. i want to work with the Arial Unicode MS font, that is installed on my system and which DOES appear in the getAvailableFonts() list!!!
But when i try to display a greek text i see not all glyphs correctly. What have i to do??
Have I still to set up my font.properties file and if so how can i manage this
thanx a lot

To me, it looks as if your problem is that you're only calling setFont on "this".
That's only going to set it for the top level frame, and doesn't always do it for every individual component. The easy way to get around this is to go berserk with the setFont call. Set it on anything (heck, set it on your dog if it makes you feel any better)! ;D
The slightly harder but smarter way to do this is to write a recursive function that drills down your component list.
public void setFontRecursively(Font myFont, Component comp) {
   comp.setFont(myFont);
   if (comp instanceof Container) {
      Component[] childComps = ((Container)comp).getComponents();
      if (childComps != null) {
         for (int i=0; i < childComps.length; i++) {
            setFontRecursively(myFont, childComps);
That should basically cover anything bar popup menus and drop-down submenus. You have to recall this as they appear, or they don't get the font straight off.
Hope that helps!

Urdu subtitles (problems with Unicode)

I have a major problem where I have a number of subtitle documents in Word with the text in Urdu. I can save these documents as Unicode txt files and they seem to be okay. However, when I import into Encore the subtitles look different (they still look like some kind of Arabic text but different). I've gone round in circles over this and have run out of ideas!!

In that case it may be worth to test
Lemony Subtitler
to prepare the bitmaps (and the script). The Lemony site says that it has
"Full Unicode support. With support for vertical and right-to-left scripts, ligatures, etc."

Problem with Unicode and Oracle NCLOB fields

When I try to INSERT a new (N)CLOB into an Oracle database, all is fine until I use a non-ASCII character, such as an accented roman letter, like the "�" (that's '\u00E9') in "caf�" or the Euro Currency symbol "?" (that's '\u20AC' as a Java character literal, just in case the display is corrupted here too). This doesn't happen with "setString", but does happen when streaming characters to the CLOB; however, as Oracle or the driver refuse strings larger than 4000 characters, and as I need to support all the above symbols (and many more), I'm stuck.
Here's the background to the problem (I've tried to be detailed, after a lot of looking around on the web, I've seen lots of people with similar problems, but no solutions: I've seen and been able to stream ASCII clobs, or add small NCHAR strings, but not stream NCLOBs...).
I'm using Oracle 9.2.0.1.0 with the "thin" JDBC driver, on a Windows box (XP Pro). My database instance is set up with AL32UTF8 as the database encoding, and UTF8 as the national character set.. I've created a simple user/schema, called LOBTEST, in which I created two tables (see below).
The basic problems are :
- with Oracle and JDBC, you can't set the value of a CLOB or NCLOB with PreparedStatement's setString or setCharacterStream methods (as it throws an exception when you send more than 4000 characters)
- with Oracle, you can only have one LONG VARCHAR-type field per table (according to their documentation) and you MUST read all columns in a set order (amongst other limitations).
- with a SQL INSERT command, there's no way to set the value of a parameter that's a CLOB (implementations of the CLOB interface can only be obtained by performing a SELECT.... but obviously, when I'm inserting, the record doesn't exist yet...). Workarounds include (possibly) JDBC 4 (doesn't exist yet...) or doing the following Oracle-specific stuff :
INSERT INTO MyTable (theID,theCLOB) VALUES (1, empty_clob());
SELECT * FROM MyTable WHERE theId = 1;
...and getting the empty CLOB back (via a ResultSet), and populating it. I have a very large application, that's deployed for many of our customers using SapDB and MySQL without a hitch, with "one-step" INSERTS; I can't feasibly change the application into "three-step INSERT-SELECT-UPDATE" just for Oracle, and I shouldn't need to!!!
The final workaround is to use Oracle-specific classes, described in:
http://download-east.oracle.com/otn_hosted_doc/jdeveloper/904preview/jdbc-javadoc/index.html
...such as CLOB (see my example). This works fine until I add some non-ASCII characters, at which point, irrespective of whether the CLOB data is 2 characters or 2 million characters, it throws the same exception:
java.io.IOException: Il n'y a plus de donn?es ? lire dans le socket
     at oracle.jdbc.dbaccess.DBError.SQLToIOException(DBError.java:716)
     at oracle.jdbc.driver.OracleClobWriter.flushBuffer(OracleClobWriter.java:270)
     at oracle.jdbc.driver.OracleClobWriter.flush(OracleClobWriter.java:204)
     at scratchpad.InsertOracleClobExample.main(InsertOracleClobExample.java:61)...where the error message in English is "No more data to read from socket". I need the Oracle-specific "setFormOfUse" method to force it to correctly use the encoding of the NCLOB field, without it, even plain ASCII data is rejected with an exception indicating that the character set is inappropriate. With a plain CLOB, I don't need it, but the plain CLOB refuses my non-ASCII data anyway.
So, many many thanks in advance for any advice. The remainder of my post includes my code example and a simple SQL script to create the table(s). You can mess around with the source code to test various combinations.
Thanks,
Chris B.

The solution to this is to use a third-party driver. Oranxo works really well.

Problem with unicode in 80GB Classic

I listen to a lot of foreign bands and artists, mainly Japanese bands. I recently changed some of the artists' names to unicode, in order to separate them from the Non-Japanese bands on the last.fm site. Everything looks fine in iTunes when I view them, but when I go to look at the list of artists in my iPod, I have some artist names listed multiple times, some with the new unicode writing, others the regular font. I have checked for trailing spaces, etc., but I still get the same result. Does the iPod not support unicode, or is there something I can do to fix this?

I got it fixed now. I just had to make sure that all the songs also had the album artist in unicode.

Problem with charsets for foreign languages

hi
i have a problem with a webapplication
in my webapplication i have some code that gets data from a webpage of another webapplication. This other web application can use many foreign languages
the problem is that those foreign languages contain some special characters, and those special chars aren't displayed the right way
this is the code to get the data from the other webapp
private static StringBuffer getContent(String sUrl) throws MalformedURLException, IOException {
        StringBuffer content = new StringBuffer();
        URL url = new URL(sUrl);
        HttpURLConnection httpURLConn = (HttpURLConnection) url.openConnection();
        httpURLConn.setRequestProperty("charset", "utf-8");
        BufferedReader buffReader = new BufferedReader(new InputStreamReader(httpURLConn.getInputStream()));
        String inputLine;
        while ((inputLine = buffReader.readLine()) != null) {
            content.append("\n" + inputLine);
        return content;
    }as you see , i tried to set the encoding to UTF-8 but that did not solve the problem

Problem with running multiple servlet in same webapplication with tomcat 3

Hi all,
I am using Tomcat 3.0 as webserver with jdk1.3, Servlet 2.0,
Templates for html file and oracle 8i on UNIX platform.
I have problem with multiple servlet running same webapplication.
There are two servlet used in my application. 1) GenServlet.class
and 2) ServletForPrinting.class
All of my pages go through GenServlet.class which reads some property files
and add header and footer in all pages.
I want reports without header & footer that is not possible through GenServlet in my application.
So I have used another servlet called ServletForPrinting --- just for reading html file.
It is as follow:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class ServletForPrinting extends HttpServlet {
public void service (HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException
// set content-type header before accessing the Writer
response.setContentType("text/html");
PrintWriter out = response.getWriter();
File f1 = null;
String report = null;
String path = request.getPathInfo();
try{
String p = "/var/home/latif/proj/webapps/WEB-INF/classes" + path;
System.out.println(p);
f1 = new File(p);
p = null;
if (f1.exists()) {
FileReader fr = new FileReader(f1);
BufferedReader br = new BufferedReader(fr);
report = new String();
while ((report = br.readLine()) != null) {
out.println(report);
}catch(Exception e) {
out.close();
report = null;
path = null;
f1 = null;
} // end class
It works fine and display report properly.
But now Problem is that if report is refreshed many times subsequently,
WebServer will not take any new change in any of java file used in web-application.
It works with the previous class only and not with updated one.
Then I need to touch it. As soon as I touch it, webserver will take updated class file.
Anybody has any idea regarding these situation?
Is there any bug in my ServletForPrinting.java ?
Any solution ????? Please suggest me.
Suggestion from all are invited. That will help me a lot.
Thanks in advance

Feel free to delete this topic.
I would strongly suggest at least reading this tutorial to give you an idea of why your fix worked (or maybe only appeared to work). Myself, I never just throw up my hands and say, "Whatever," and wash my hands of the situation without trying my best to understand just what fixed it. Guranteed you'll run into the same/similar problem and this time your fix won't work.
Please do yourself a favor and try to understand why it is working now, and save yourself (or more likely, the next poor dev to work on this project) some heartache.

Problem with field-symbols in UNICODE conversion

Hi all.
I'm in a UNICODE conversion project and I have a problem with a program that uses field-symbols.
DATA: BEGIN OF wa_data_aux,
        mandt LIKE zindices-mandt,
        kschl LIKE zindices-kschl,
        datab LIKE zindices-datab,
        valor LIKE zindices-valor,
        descripcion LIKE zindices-descripcion,
        ernam LIKE zindices-ernam,
        erdat LIKE zindices-erdat,
        waers LIKE zindices-waers,
      END OF wa_data_aux.
FIELD-SYMBOLS:
               <fs2> TYPE ANY,
               <fs3> LIKE wa_data_aux.
          <fs2> = <fs3>.
This assignment results in a DUMP.
Can anybody help me to solve this problem?
Thanks!!

TYPES: BEGIN OF wa_data_aux,
          mandt TYPE mandt,
          kschl TYPE kschl,
          erdat TYPE d,
          waers TYPE waers,
      END OF wa_data_aux.
DATA: w_aux TYPE wa_data_aux.
FIELD-SYMBOLS:
<fs2> TYPE ANY,
<fs3> TYPE wa_data_aux.
w_aux-mandt = '300'.
ASSIGN w_aux TO <fs3>.
ASSIGN <fs3> TO <fs2>.
WRITE : / <fs2>.
GBY.

Problem when compiling C program from RFC SDK with Unicode on AIX 5.3

hi friends.
I try RFC with UNICODE.
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/90313271-2311-2a10-c495-c20199d1d821
This simple code compiled.
#include <saprfc.h>
#include <sapuc.h>
#include <sapucx.h>
int mainU(int argc, SAP_UC* argv[] )
    const SAP_UC* s1 = cU("Hello");
    SAP_UC s2[100];
    strcpyU( s2, s1);
    printfU(cU("%s
"),s2);
    return 0;
The compiling command is
cc -DSAPwithUNICODE -I ../rfcsdkU/include -L ../rfcsdkU/lib sample.c -o sample -lrfcu -lC
to compile.
Then the error information comed:
"sample.c", line 7.24: 1506-045 (S) Undeclared identifier U16LIT_cU.
"sample.c", line 7.27: 1506-275 (S) Unexpected text string literal encountered.
"sample.c", line 10.16: 1506-276 (S) Syntax error: possible missing ')'?
I hope someone can tell me how I can get it through.

Problem with syntaxes and structures in unicode

1. i have a problem with syntax
this is old syntaxes
TRANSLATE c ...FROM CODE PAGE g1 ... TO CODE PAGE g2
new systems should use this class instead of above
CL_ABAP_CONV_IN_CE
it reads data from a container and converts it to the system format.
my old syntax is TRANSLATE header-id FROM CODE PAGE file_tab-codepage.
i need to change to new one by using above class how to do it
2. I have a structure are_buffer and i am working on upgrade of a old report , i have used a sap predefined structure callled arc_buffer from se11, now when i am using offset in one of the perform statement like
PERFORM read_file USING handle_tab_wa-offset record_len
CHANGING arc_buffer(record_len)
error_handling
p_message.
but the system throws a error called ''the structure arc_buffer(record_length) does not start with character-type field''.
i cannot change the structure becoz its sap standard structure .
how to get out of this.
