Handling Special characters in JSP

Hi,
I have migrated some data from SQL server database to Oracle.
while migrating i encountered a special character "�", which i need to display in the JSP page.
But when i display this in the JSP it shows me as "�"
I tried using <%@page pageEncoding="UTF-8"%>
and
<% response.setContentType( "text/html; charset=utf-8" ); %>
and also utf-16. but of no use.
Please help me and let me know how can i display � instead of �
Thanks and Regards,
Raju

Did the character migrate successfully to the Oracle Database? What value is in there?
What is the type of the oracle field you are storing this character in?
This is a very useful article on the subject. It might help you solve the problem:

Handle special characters in JSP

Hai all,
i am getting a problem, when i copy some text from word file and paste it in my forms textarea. If the selected text contains characters like " or ', e.g. (Hello Everybody.) then after submiting it is replaced as a ? mark. How to handle this.
Thanks

You need to set the correct character encoding (charset) and use the same thoroughout the whole process.
This is an excellent read: [http://www.joelonsoftware.com/articles/Unicode.html].

Time-dependent Vendor Master & Handling Special Characters

Hi,
I need to extract time-dependent Vendor Master.
1. The data source for 0VENDOR does not have fields to hold the valid date range.
2. Does the Master data in R/3 for Vendors will hold the valid date range?
3. The text for 0VENDOR provides time-dependent, but how to map the valid from and valid to fields?
Handling Special Characters:
We are trying to extract data from Legacy system via DB Connect. The item text field consists of special characters. Of course in BW customization we can specify all the special characters to consider. But the special character we observed is 'square' symbol i.e. 'new line character' in Oracle. We are updating this to an ODS object. When looked at error log, observed that green light for the number of records transferred and updated, but finally when it load into ODS object and activates popping up the error message saying 'could not recognize special character'.
Please help me getting the 2 issues resolved.
Thanks in advance.

 DO.
 IF DATA_PACKAGE-/BIC/ZI_DESC CN ALLOWED_CHAR.
 REPLACE SECTION OFFSET SY-FDPOS LENGTH LEN OF

 FLAG = SPACE.
 ELSE.
 FLAG = 'X'.
 ENDIF.
 IF FLAG = 'X'.
 EXIT.
 ENDIF.

 MODIFY DATA_PACKAGE.
ENDLOOP.
if abort is not equal zero, the update process will be canceled

Handling special characters in XML

Hi,
I am using Oracle 10g 'XMLType' datatype to store XML files. Before storing I parse the XML document using Java Xerces Parser. If it parses successfuly, then I perform some business rule execution based on XML file which was parsed. So till this stage there is no problems. But when XML file contains some special characters like copy-paste of some description from MS-Word document into XML tags, then Xerces parser will parse such characters with out any exceptions, but while inserting XML document, Oracle database just throws exception saying unable to handle special characters.. So how to avoid such exceptions or silent such exceptions with any specific settings respect to XMLType datatype in 10g DB.
Please advice!

In XI 2.0, we've noticed a number of issues processing special characters, primarily caused by the version of JCO that we're running. It sounds like SAP has spent some time in the past few months focusing on these errors, so make sure you're on the most recent patchlevels of all your middleware components, including any of the middleware libraries that BC uses. In XI, we had to update the 3 files that make up the RFC library and JCO library. SDM couldn't update the libraries for us -- we had to manually move the files to the right place.
Escaped XML characters like "&" """ """ were fixed as of JCO 2.0.10 (the current patchlevel on AIX/UNIX), the special character "'" is fixed in the next release, JCO 2.0.11, due out in a few weeks (hotfixes are available). I don't know the equivalent versions on other platforms. By default, XI 2.0 appears to have shipped with JCO 2.0.5. I would expect many XI 3.0 users to also be affected.
This may or may not apply to BC, because I don't know what BC uses to talk to SAP under the covers.

Handle special characters in the attribute name

Hi,
I am generating different view element in WD application dynamically. How to handle special characters other than '-/ABCDEFGHIJKLMNOPQRSTUVWXYZ_0123456789' for the attribute name dynamically?
Thank you, in advance.
Trupti

Going with the obvious response - don't use them?
if you're using dynamic code, there is no reason (other than debug support) to give your created elements any meaningful name.
Just generate a GUID for each new element and use that.
If you need to be able to later search for and update the element a simple lookup table of GUID to reference string should work reasonably well.

Chris

How to handle special characters in NWDI

Dear All
I am trying to update the Description from JSP form. Through JCO we are calling the RFC of ABAP. We are passing these description from Java to RFC of ABAP and this RFC update the text in Database.
We have noticed that if there is some special character in description like as : or , complete description is not getting updated in to the SAP database.
Can anyone help me how to handle these special characters in Java. There may be N number of special characters. We want to generalize it. We want to replace these characters by s and z respectively.
For example : We want to update this description.

Hi Bhavishya,
Apparently your SAP database isn't configured to support Unicode. That would be the first solution to your problem, but I can imagine it's a bit drastic to convert your DB.
A second solution would be to encode the input description to ASCII before storing it in the database. When reading from the database, decode again to Unicode. This way, no information is lost. A suitable encoding would be Base64. e.g.
String description = "unday ebra";
String descriptionBase64 = new sun.misc.BASE64Encoder().encode(
description.getBytes("UTF-8")); // ""
// store descriptionBase64 in the DB
// later, when reading descriptionBase64 from the DB
String description2 = new String(
new sun.misc.BASE64Decoder().decodeBuffer(descriptionBase64), "UTF-8");
Instead of using Sun's implementation, a better alternative is to use the open source implementation
org.apache.commons.codec.binary.Base64 from Commons Codec .
The 3rd approach is indeed to normalize the description by replacing all special characters with their ASCII equivalent. A rather easy solution is as follows:
String description = "unday ebra";
String descriptionNormalized = sun.text.Normalizer.normalize(
description, sun.text.Normalizer.DECOMP, 0).replaceAll(
"[^p{ASCII}]", "");
sun.text.Normalizer decomposes the string, e.g. "éàî" becomes "e´a`i^", after which non-ASCII characters are being removed using a regular expression.Again, note that it's usually a bad idea to use sun.* packages, see note about sun.* packages. The above code only works with J2SE 1.4 and J2SE 5.0, but it breaks in J2SE 6.0 (where
java.text.Normalizer became part of the public API ;-). A good open source implementation can be found here: ICU4J (com.ibm.icu.text.Normalizer).
Kind regards,

How to handle special characters such as apostrophe, ampersant

Hello All,
Tools:
JSP, JSDK 2
Oracle 8
Issue:
If the user supplies a String value inside a text box which has special characters such as apostrophe, while we try to compare that string with some value in the database, the sql error comes up as the sql string will be broken.
Example:
input string--> ABC D'OLL
sql --> "select * from verndor where vendor_name ='ABC D'OLL' "
Present solution:
I am reading each input string & look for such special characters. if so, replaces that character with escape character + that character.
This solution works.
Problem:
If there any more efficient way to handle such character??
At java level or Database level
Thanks In advance :)

How to Handle Special Characters in PI7.1

Hi Team,
I need to handle some special characters like <,>,& etc.. from WS Adapter to CRM in PI 7.1.
http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/9420 [original link is broken]
By using the above blog i had implemented the Java Code as
public void execute(InputStream in, OutputStream out){
try{
int read_data;
while((read_data = in.read()) != -1){
if (read_data == '&'){
out.write("&".getBytes());
}else if (read_data == '>'){
out.write(">".getBytes());
}else if (read_data == '<'){
out.write("<".getBytes());
}else if (read_data == '/'){
out.write("&frasl;".getBytes());
}else if (read_data == '\''){
out.write("'".getBytes());
else { out.write(read_data);
out.flush();
} catch (Exception e){}
I had added this class file in Operational Mapping.
It is working if we have only one IF condition for & in while
Any suggestion
Thanks
Sriram

Hi Ramesh,
Thanks for your inputs, I have tried your code but it is not working. The error message stays the same.
Dear Stephane,
To describe the error more, the requirement is the payload coming from source through WS Adapter consists of the special characters <, > , & which are basic sematics of XML syntax. I need PI to process this payload with special characters and successfully transfer it to target CRM system. I have created the Java class with code (ref: Blog 9420) as stated earlier and added this class to my existing Operation Mapping. I am expecting the java mapping to replace the special characters in payload like < with ">" . So as the case with the other characters >,&,'
After activaton of my operation mapping, I triggered the test message with Soap UI client and I could able to get a successful mapping only When I put the logic for &ampersand symbol only. However when I am trying to add the logic for > or < or ' the mapping is failing . I am using UTF-8 encoding across the source and PI enviroments.

Error while handling special characters ( and &) in Sender File adapter

Dear All,
Scenario: Third Party System --> (File adapter) SAP PI 7.1 (SP05) --> (Proxy) ECC
We are receiving CSV file and no mapping is required in PI as all the processing is being done by third party tool. But we are receiving special characters like ',",>,< and & in the csv file.
When we are using File Type as TEXT and File Encoding as ISO-8859-1 than we are getting error. We changed File Type to BINARY and than we are able to handle ',",> but having issue in handling < and &.
Any idea how we can handle it.
Please note trhere is no Mapping in SAP PI so cannot uise Java mapping.
Thanks a lot
Chanakya

Hey,
You can add ABAP Script in Receiver Proxy for eliminating or replacing with NULL or empty. Since you dont have mapping for formatting these kind of junks you can follow the above approach.
Else, you can remove the junks at OS level while running a small script and make it available to PI.
Or else, you need to create mapping for sender and recevier structure though it is same, then you add a very simple UDF for fine tune.
Use this UDF
Here a is the input value.
String b = "";
b = a.replaceAll(",", "0");
b = a.replaceAll("@", "0");
Like all the special characters you can take and replace with zero.
return b;
Thanx

Handling Special characters in the data set

Hi All,
I am facing an issue in hadling special characters while writing data to a flat file.
The data fetched in toad query is *44CAÑADO* (with some specail character over N), but when this same data is written in textpad using UTL_FILE.put_line, the data written is converted to *44CAÃ‘ADO*.
Can anyone please help me how to handle these special charatcers so that the same data is written in text file as well.
Regards,

To find the database characterset, please see (Character Sets & Conversion - Frequently Asked Questions [ID 227330.1] -- 2. What is the database character set used for and how is it set?)

Problems with special characters in JSP app

Hello!
I am working for a JSP application which uses special characters.
The database used is a Novell MySQL version, it is fine.
I use Tomcat, Apache.
I do not think that the versions are important.
ON NT:
The application works fine with special characters.
Obs: I tried only with Tomcat; I didn't use Apache.
ON NOVELL:
If I try to insert some special characters,
they arrive just fine into the database.
The problem is when I want to display them.
I tried with jsp directive to set the charset,
or with HTML meta tag - no result al all.
Everytime I use the same work station, and the same browser to do the tests.
Please help with any ideas.
Another question, maybe relayed:
Can I set Tomcat so that when it creates the servlets it uses a custom charset I can indicate?
THANK YOU!

The characters I want to use are french characters, e-acute, etc.
I take the data with request.getParameter, POST method, etc.

Handle special characters in xml

Hi,
Our end users tend to copy the description text from Word documents to pdf form and submits it.
If that text contains any special characters, its getting carried to the extracted xml. In the next step, when I try to assign a task to user with template and this xml, Managers cannot able to open the form and showing the error. When I assign the xml without special characters, its running fine.
Please assist on how to handle this?
My expectation is that user should be prompted in the form when he pastes any special characters or they should be auto-corrected to null values. if that is not possible, atleast we should able to filter the xml and eliminate special characters before the form go to next stage.
Appreciate your help.
Thanks,
Krishna

In first instance, I would have followed this way:
http://www.dvteclipse.com/documentation/svlinter/How_to_use_special_characters_in_XML.3F.h tml
so, I would have parsed the submitted text in a Validate event and changed any special chars to UTF-8 numeric reference.
However, I found this:
http://blog.mark-mclaren.info/2007/02/invalid-xml-characters-when-valid-utf8_5873.html
which seems to state that not all UTF-8 characters are possible in XML.
In fact, those allowed are listed here:
http://www.w3.org/TR/2000/REC-xml-20001006#NT-Char
so, I would still use a Validate event script but based on the XML specs' Character Range. Exactly as Mark McLaren did in Java.
This will permit to keep those special chars that are allowed. Your Managers will thank you.
Hope it helps.

Is there any other way to handle special characters other than using CDATA?

How to handle special characters in Apex

Hi ,
In my application I have two regions - one is Report Region (Interactive Report) and other one is HTML region with two text items - Empno and name
My Report has two columns Empno(varchar2) and Ename(varchar2).
When I click the edit link in the report column, the empno should have a read only EMPNO value and ename is a text field with ENAME value.
When I run my application I have encountered the following problems :
1. if my empno has special characters like ' # ', the characters after that is not getting displayed
2. if my empno has special characters like ',' - the characters after comma is treated as a next texitem value

Don't pass data values in URLs. Whilst it is possible to escape values to make them URL- and APEX parameter-safe, it is much better practice to avoid the problem altogether.
Create a surrogate primary key on the table that is an immutable discrete numeric identifier and only use this as a URL parameter. In target pages/regions, use this PK value to retrieve the required data from the table.
