BC4J with Double Byte

Is it possible that I can create BC4J to access a 8i with ISO8859-1 characterSet, and show double byte information
(ex:Chinese/Japaness) correctly in my applet? (ex:GridControl) So far I can only show Chinese correctly in my BC4J,
when the 8i with a ZH16BIG5 character Set.
Thanks for any idea. : )

Crystal XI R2 exporting issues with double-byte character sets

NOTE: I have also posted this in the Business Objects General section with no resolution, so I figured I would try this forum as well.
We are using Crystal Reports XI Release 2 (version 11.5.0.313).
We have an application that can be run using multiple cultures/languages, chosen at login time. We have discovered an issue when exporting a Crystal report from our application while using a double-byte character set (Korean, Japanese).
The original text when viewed through our application in the Crystal preview window looks correct:
性能著概要
When exported to Microsoft Word, it also looks correct. However, when we export to PDF or even RPT, the characters are not being converted. The double-byte characters are rendered as boxes instead. It seems that the PDF and RPT exports are somehow not making use of the linked fonts Windows provides for double-byte character sets. This same behavior is exhibited when exporting a PDF from the Crystal report designer environment. We are using Tahoma, a TrueType font, in our report.
I did discover some new behavior that may or may not have any bearing on this issue. When a text field containing double-byte characters is just sitting on the report in the report designer, the box characters are displayed where the Korean characters should be. However, when I double click on the text field to edit the text, the Korean characters suddenly appear, replacing the boxes. And when I exit edit mode of the text field, the boxes are back. And they remain this way when exported, whether from inside the design environment or outside it.
Has anyone seen this behavior? Is SAP/Business Objects/Crystal aware of this? Is there a fix available? Any insights would be welcomed.
Thanks,
Jeff

Hi Jef
I searched on the forums and got the following information:
1) If font linking is enabled on your device, you can examine the registry by enumerating the subkeys of the registry key at HKEY_LOCAL_MACHINEu2013\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontLink\SystemLink to determine the mappings of linked fonts to base fonts. You can add links by using Regedit to create additional subkeys. Once you have located the registry key that has just been mentioned, from the Edit menu, Highlight the font face name of the font you want to link to and then from the Edit menu, click Modify. On a new line in the dialog field "Value data" of the Edit Multi-String dialog box, enter "path and file to link to," "face name of the font to link".u201D
2) "Fonts in general, especially TrueType and OpenType, are u201CUnicodeu201D.
Since you are using a 'true type' font, it may be an Unicode type already.However,if Bud's suggestion works then nothing better than that.
Also, could you please check the output from crystal designer with different version of pdf than the current one?
Meanwhile, I will look out for any additional/suitable information on this issue.

Trouble with double byte swapping routine

I'm working on a program that reads little endian doubles from a DataInputStream and then swaps them. Usually, everything works fine. However, certain values don't swap correctly.
I'm at a total loss as to why this is happening, so I hoped one of you guys could show me. I've included a demonstration program with the method I'm using to swap doubles.
public class SwapTest
     public static void main(String[] args)
          new SwapTest();
     public SwapTest()
          // The swap routine works well with this value
          double d = 0.8660252094218776d;
          System.out.println("d before being swapped: " + d);
          // Swap to small order, then back to big order
          d = swapBytes(d);
          d = swapBytes(d);
          System.out.println("d after being swapped: " + d);
          System.out.println();
          // Everything gets totally hosed with this value
          d = 0.8660252079425844d;
          System.out.println("d before being swapped: " + d);
          // Swap to small order, then back to big order
          d = swapBytes(d);
          d = swapBytes(d);
          System.out.println("d after being swapped: " + d);
     private static double swapBytes(double sm)
          long smallendian = Double.doubleToLongBits(sm);
          long result;
          long l1 = (smallendian & 0x00000000000000FFL) << 56;
          long l2 = (smallendian & 0x000000000000FF00L) << 40;
          long l3 = (smallendian & 0x0000000000FF0000L) << 24;
          long l4 = (smallendian & 0x00000000FF000000L) << 8;
          long l5 = (smallendian & 0x000000FF00000000L) >>> 8;
          long l6 = (smallendian & 0x0000FF0000000000L) >>> 24;
          long l7 = (smallendian & 0x00FF000000000000L) >>> 40;
          long l8 = (smallendian & 0xFF00000000000000L) >>> 56;
          result = l1 | l2 | l3 | l4 | l5 | l6 | l7 | l8;
          return Double.longBitsToDouble(result);
}

The doubleToLongBits() method converts invalid values to NAN before converting

JSF and Double Byte Character

Hi,
I wanted to know how to handle <h:outputText> with chinese character or double byte character.
See sample code below :
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<h:form styleClass="form" id="form1">
<% request.setCharacterEncoding("UTF-8"); %>
<h:inputText styleClass="inputText" id="text1"></h:inputText>
<hx:commandExButton type="submit" value="Submit" styleClass="commandExButton" id="button1" action="#{pc_SubmitTest.doButton1Action}"></hx:commandExButton>
<h:outputText styleClass="outputText" id="text2"></h:outputText>
</h:form>
When you input with double byte character and submit,
the output screen value did not render properly .
I tried this similiar code at JSP, it work fine.
Anybody know how to solve this problem ?
Anything need to do at pagecode level ?
Thank you.

Double byte characters turn into squares at PDF export use Unicode font

Hi all,
We developing with Visual Studio 2008, .NET 2.0 and Crystal Report XI Release 2 SP5 an international windows application. We use the font Arial Unicode MS in the rpt file. We translate the fix texts with the Crystal Translator (3.2.2.299).
On the distributed installation of our software, the printout and preview displays the double byte characters properly (Japanese, Korean, Chinese), but when we export the report as PDF, the characters get displayed with squares. This happens also, when the font Arial Unicode MS is installed on the distributed installation on Windows XP Professional.
I searched for hours for a solution in the knowlegde base articles and in forum of Crystal Report. I found one thread, which describes exactly our problem:
[Crystal XI R2 exporting issues with double-byte character sets|Crystal XI R2 exporting issues with double-byte character sets;
But we already introduced the solution to use Unicode font and I also linked the font Lucida Sans Unicode to the Arial Unicode MS, but we still face the problem.
Due to our release on thursday we are very under pressure to solve this problem asap.
We appreciate your help very much!
Ronny

Your searches should have also come up with the fact that CR XI R2 is not supported in .NET 2008. Only CR 2008 (12.x) and Crystal Reports Basic for Visual Studio 2008 (10.5) are supported in .NET 2008. I realize this is not good news given the release time line, but support or non support of cr xi r2 in .net 2008 is well documented - from [Supported Platforms|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/7081b21c-911e-2b10-678e-fe062159b453

Sapshcut and double-byte characters trouble?

Hi experts,
I did try some commands to log-on to SAP system as the following examples and get some conclusions:
(1) sapshcut.exe -sysname="今ウィ　ちゃわ異" -user="paragon1" -pw="paragon1" -client="800" -language=en -maxgui "
(2) sapshcut.exe -sysname="EC5" -user="paragon1" -pw="paragon1" -client="800" -language=en -maxgui "
- For the (1) case, with any "double-byte characters" sysname (Janpanese,...), I can not log-on to SAP and get "Microsoft Visual C++ Runtime Library" error message.
- For the (2) case, without "double-byte characters" sysname, I can log-on to SAP easily.
Thus, I wan to know
1) Does the sapshcut.exe support double-byte characters?
2) Do we have a way to use sapshcut.exe with double-byte characters(Japanese,...)?
Kindly Regards,

The comments on the bytes/strings were helpful. Thanks.
But I'm still confused as to what matching pattern could be used.
For example a pattern like:
[A-Za-z]
I assume would not match any double byte characters.
I also assume the following won't work either:
[\\p{Alpah}]
because it is posix - US-ASCII only.
So how do you say "match the tag, then take any characters,
double byte, ascii, whatever, then match the text tag - per the
original example ?

Double byte stream name

Hi,
is it possible to play RTMP stream with double byte name like japanese korean etc.. ?
I tried to with and without escape() stream name without success
lke "rtmp://server.com:1935/app/"+escape(streamName)
doesn't work
thanks
Franck

I tried it out, and I am able to play RTMP stream with double byte character as stream name, in both vod and live.
What stream name are you giving? Can you explain a bit further the steps you are following.

How to display double byte characters with system.out.print?

Hi, I'm a newbie java programmer having trouble to utilize java locale with system io on dos console mode.
Platform is winxp, jvm1.5,
File structure is:
C:\myProg <-root
C:\myProg\test <-package
C:\myProg\test\Run.java
C:\myProg\test\MessageBundle.properties <- default properties
C:\myProg\test\MessageBundle_zh_HK.properties <- localed properties (written in notepad and save as Unicode, window notepad contains BOM)
inside MessageBundle.properties:
test = Hello
inside Message_zh_HK.properties:
test = 喂 //hello in big5 encoding
run.java:
package test;
import java.util.*;
public class Run{
public static void main(String[] args){
    Locale locale = new Locale("zh","HK");
    ResourceBundle resource =
        ResourceBundle.getbundle("test.MessageBundle", locale);
    System.out.println(resource.getString("test"));
}//main
}//classwhen run this program, it'll kept diplay "hello" instead of the encoded character...
then when i try run the native2ascii tool against MessageBundle_zh_HK.properties, it starts to display monster characters instead.
Trying to figure out what I did wrong and how to display double byte characters on console.
Thank you.
p.s: while googling, some said dos can only can display ASCII. To demonstrate the dos console is capable of displaying double byte characters, i wrote another helloWorld in chinese using notepad with C# and compile using "csc hello.cs", sure enough, console.write in c# allowed me to display the character I was expecting. Since dos console can print double byte characters, I must be missing something important in this java program.

after google a brunch, I learned that javac (hence java.exe) does not support BOM (byte order mark).
I had to use a diff editor to save my text file as unicode without BOM in order for native2ascii to convert into a ascii file.
Even the property file is in ascii format, I'm still having trouble to display those character in dos console. In fact, I just noticed I can use system.out.println to display double byte character if I embedded the character itself in java source file:
public class Run {
     public static void main(String[] args) throws UnsupportedEncodingException{
          String msg = "中文";    //double byte character
                try{
                System.out.println(new String(msg.getBytes("UTF-8")) + " new string"); //this displays fine
                catch(Exception e){}
                Locale locale = new Locale("zh", "HK");
          ResourceBundle resource = ResourceBundle.getBundle("test.MessagesBundle", locale);
                System.out.println(resource.getString("Hey"));      //this will display weird characterso it seems like to me that I must did something wrong in the process of creating properties file from unicode text file...

HOWTO: Use BC4J With or Without DB Triggers

This HowTo describes how to use BC4J, database sequences and triggers
and what are the ramifications.
INTRODUCTION
BC4J has the ability to work with database sequences in order to obtain a
unique value when inserting records. BC4J also has the ability to
work either with a 'before insert' trigger which automatically creates
a new unique value for the primary key or without a trigger. When not using
a database trigger, BC4J also has the ability to obtain the sequence value
and set the primary key value.
Before discussing the ramifications of using one approach or the other, let's
show examples of how to use both approaches:
BC4J & sequences WITH a database trigger
and
BC4J & sequences WITHOUT a database trigger
HOWTO DEMONSTRATION STEPS
To illustrate both scenarios a simple database setup script is provided which
creates two tables:
CUSTOMER_NT which DOES NOT have a before insert trigger and
CUSTOMER_WT which DOES have a trigger.
Database Install Script:
<code>
drop trigger customer_insert_trigger;
drop table customer_wt;
drop table customer_nt;
drop sequence customer_wt_seq;
drop sequence customer_nt_seq;
create sequence customer_wt_seq start with 1;
create sequence customer_nt_seq start with 101;
create table customer_wt(
id number,
name varchar2(30),
constraint
customer_wt_pk
primary key (id)
create table customer_nt(
id number,
name varchar2(30),
constraint
customer_nt_pk
primary key (id)
prompt Inserting data...
insert into customer_wt (id, name)
values (customer_wt_seq.nextval, 'Mickey');
insert into customer_wt (id, name)
values (customer_wt_seq.nextval, 'Goofy');
insert into customer_nt (id, name)
values (customer_nt_seq.nextval, 'Daffy');
insert into customer_nt (id, name)
values (customer_nt_seq.nextval, 'Porky');
commit
prompt Creating trigger
create trigger customer_insert_trigger
before insert on customer_wt for each row
begin
select customer_wt_seq.nextval into :new.id from dual ;
end;
</code>
The next step is to create the DEFAULT Entity Objects and View Objects using
the Business Components Wizard.
USING BC4J WITH A DATABASE TRIGGER
Let's modify the entity object CustomerWt so it can use the database trigger.
Edit the entity object CustomerWt by right-clicking in the navigator.
Click on the 'Attribute Settings' tab and edit the ID attribute.
- Uncheck 'Mandatory'checkbox. This allows you to insert without a value for the primary key
- Check 'Refresh after Insert'. This obtains the value from the database generated by the trigger.
- Check 'Updateable While New'. Id is only updateable when inserting.
Click finish to complete the wizard. Save all and recompile the project.
Now let's test our work.
In the navigator right-click the application module and select 'Test..'. This will launch
BC4J's built in tester. Connect to the application.
In the tester double-click the CustomerWtView view object to run a test edit form.
After the edit form renders, navigate through the existing records using the navigate
buttons on the edit form. Now let's insert a record to execute the trigger.
click on the '+' button to insert a record. Enter a value in the 'Name' field and commit the change.
Observe that a new value has automatically been inserted into the Id field.
That's it! You have successfully used BC4J and a database trigger.
Now let's try it without a trigger..
USING BC4J WITHOUT A DATABASE TRIGGER
Now edit the entity object CustomerNT so it doesn't need a database trigger.
Similar to before, edit the entity object CustomerNt by right-clicking in the navigator.
Click on the 'Attribute Settings' tab and edit the ID attribute.
- Uncheck 'Mandatory'checkbox.
- Check 'Updateable While New'.
An additional step is also required. The Create method will have to be modified to extract
the value of the sequence.
In the Edit EntityObject Wizard click the Java tab and select Create method and click Finish.
The create method is generated in your Java fil e. In the Workspace view of the Navigator,
expand the CustomerNt entity object in the navigator. Double-click
CustomerNtImpl.java to open it in the Source Editor. In the Structure pane, double-click
create(AttributeList). Modify the Create method so it looks like this:
<code>
public void create(AttributeList attributeList) {
super.create(attributeList);
SequenceImpl s = new SequenceImpl("customer_nt_seq", getDBTransaction());
Integer next = (Integer)s.getData();
setId(new Number(next.intValue())); }
</code>
Save and compile the project.
Now test the ViewObject CustomerNtView using the tester as before.
In the edit form of CustomerNTView click on the '+' to insert a record. Observe that
just as before a new value has automatically been inserted in the ID field!
TO USE A DB TRIGGER OR NOT TO USE A DB TRIGGER.
Using a Database trigger sometimes preferable if you have non BC4J applications
also sharing the database. In this case it is still safest to just let the database
update it's own primary keys.
If you don't have any other non-BC4J applications sharing the database, then not using
a database trigger is perfectly acceptable and can have slightly better performance.
The important thing to remember is that the option is yours to use either approach!
null

Thank you for the reply Jonathon. I am using a ViewObject which
consist of several tables. I haven't tried the DB trigger
approach but just using the BC4 approach in overriding the
create method.
Here is the parent class create as a part of the
FasNameImpl.java file which does the job correctly.
public void create(AttributeList attributeList) {
super.create(attributeList);
SequenceImpl l_seq = new SequenceImpl
("SEQ_CUSTOMER_ID",getDBTransaction());
Integer l_next = (Integer)l_seq.getData();
setCustomerId(new Number(l_next.intValue()));
This is when I triedpassing the value to the child table. But I
can't figure it out. I think the link is working fine if I had a
ViewLink deployed but it doesn't look like it's doing the job
for ViewObject.
I am trying to call the childclass.method
(FasCustomer.setCustomerId(l_next);
But I am getting error.
Thanks a lot for your suggestions,

Bug with double division ??

Hello,
first sorry my bad english...
I am trying to convert a C program in java and i had a big problem with double division.
For example, my program needs to do that :
double d = 2. * 3.1415926 ;
double d2=511;
double d3=d/d2;
The value in memory of d3 is 0x3f892e92965e074e whereas with my original C program, for the same code) the value in memory is 0x3f892e92965e074d !!!!!! (the last byte is different)
So what is the problem ? Is the double division in java different with the C language or is it my code which has a problem ??
Thanks a lot

It could be different than (some implementation of) C, but that doesn't mean it's a bug or a problem. Java is supposed to implement an IEEE floating point specification; if you can demonstrate that it's not following that spec (I think it's IEEE 754) then report it as a bug. Incidentally, do Java and your version of C implement 3.1415926 the same way?
(Also, if that number is supposed to be pi, then the inaccuracy you claim in Java is much less than the inaccuracy you made by using an approximation to pi.)

Text strings from VISA read don't match identical looking text constants - could it be double byte characters"

Our RS232-enabled instrument sends ASCII strings to COM 1 and I read strings in. For example I get the string "TPM", or at least it looks like "TPM" if I display it. However, if I send that to the selector input of a Case structure, and create a case for "TPM", whether the two appear to match varies. Sometimes it matches, and measuring its length returns 3. Sometimes it measures 7 or 11 or 12 characters long, and it doesn't match. I can reproduce a match or a mismatch by my choice of the command that went to the instrument prior to the command that causes the TPM response, but have made no sense of this clue. I have run it through Trim Whitespace, with Both Ends (the default) explicitly selected. I have also turned the string into a byte array, autoindexed a For loop on that, and only passed the bytes if they don't equal 32, or if they don't equal 0, thinking spaces or nulls might be in there, but no better.
The Trim Whitespace function's Help remarks that it does not remove "double byte characters". But I can't find anything else about "double byte characters". Could this be the problem? Are there functions that can tell whether there are "double byte characters", or convert into or out of them? By "double byte characters", do they just mean Unicode?
Solved!
Go to Solution.

Cebailey,
The double byte characters are generally used for characters specific to languages other than English. If you display your message in " '\' Codes Display" in a string indicator do you see any other characters? You could also use Hex Display to see count the number of bytes in the message. You are probably getting messages with non-printable characters that might need to be trimmed before using your application. If you want more information the '\' Codes Display, there's a detailed description found in the LabVIEW Help. You can also find the same information on our website in the LabVIEW Help.

Using Double Byte Characters in URL For Session Variables

When I supply the value for a session variable in the URL for an IRPT page where the value contains double byte characters, Japanese in this case, the characters are corrupted by the time they are entered for the session variables. Does anyone know a solution to this problem or experience in this area? Currently using xMII 11.5 SR3.

Hi Bryan,
I would suspect that under the covers the session variable is of datatype string. For double byte characters, it would need to be wstring. There is a better explanation to be found at:
Link: [Kanji and Java Datatypes|http://www.unix.com.ua/orelly/java-ent/jenut/ch10_04.htm] or you can try google on Kanji Datatype OR Kanji Java Datatype
It could also be a problem with the operating system which I ran into about 10 years ago, but I would hope that Microsoft had moved beyond that by now.
Maybe some more technical folks could chime in to confirm or deny my explanation.

How do I convert a double-byte encoded file to single-byte ASCII?

Hello,
I am working with XML files (apparently coded in UTF-8) which encoded in double-byte characters.
The problem is the characters for end of line: 00 0D 00 0A
This double byte end of line is causing a problem with a legacy conversion tool (which deals with 0D 0A). The file itself contains no
accented/international characters, so in principle converting to single-byte should not cause any problems.
I have tried to convert this file with tools like native2ascii and the conversion tools that are part of Notepad++ but without
any luck - the "00 0D 00 0A" are still present in the output
Can anyone point me to a tool or some code that can convet this file into single-byte?
Thank you.

Amiens wrote:
native2ascii.exe -encoding UTF-16 -reverse INPUT.xml OUTPUT.xml
gives 00 00 0 0D 00 00 00 0A
so clearly that is not the required output.What you've got there is UTF-16 encoded text that's been converted to UTF-16. Get rid of the "-reverse" option and you should see the result you expect.

Report in PDF format can not support double byte character ?

Hi :
I am developing the simplified chinese application , when i generate the report in PDF format , i found all double byte character did not display correctly . i am using dev6i+patch5 , why ?
it is a bug of form or not ???????
HELP !!!

try this ,Install acrobat4.0 or above and make sure you got acrobat distiller which will add a acrobat distiller printer in you windows. print report direct to that printer (don't change desformat) and you should got your PDF file with correct font setting.
