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.

How to display special characters in APEX Classic Report column

Ref: Thread: How to display newline characters as new lines
Version: APEX 3.2
Hi,
I have created an classic SQL Report with one of the columns being a decode that gives a value 'Post'(the value should be highlighted in Red) on one condition and 'Pre' on another. I have followed the advice given in the page (URL provided above) , i.e. I have changed Strip HTML to 'No', changed Display as to 'Display as text (escape special characters, does not save state)'. I have also passed this value back to the same page to be stored in a page item each time a link (another column in report) in report is clicked. I have tried passing it as #DEADLINE# and \#DEADLINE#\. The issue I face is, instead of the value being highlighted in Red, it gets passed back as a string holding the value 'Post'. Is there any way I can get this to display as it should without the Strip HTML being changed to 'Yes'.
Thanks very much.

Hi,
Thanks for your response.
I am trying to display a page item that is derived from a report column based on a click on the URL link (*view >*>)
This page item (here, it is Manager_ID) should ideally be highlighted when a particular condition is satisfied (achieved using a DECODE in the report).
But it is not displayed like it should be.
I do not want the value to be displayed along with the html tags as a string.
I want the html tags to take effect and highlight the value within it.
Initially, I had set Strip HTML to Yes and the value was returned without any highlighting .
So I changed it to 'No' and and it contained the html tags.
I am not sure what setting in APEX Report Attributes can help me achieve that effect I want.None of the report settings are relevant. They affect the rendering of the report and none of the columns you were changing the properties of were actually rendered.
You can't pass HTML and CSS around in URL parameters.
I suggest you pass *2* values in the column link: the MGR ID and a simple class or colour value computed by the DECODE in the report. I've suppressed the first version of the report and created a new one that does this:
decode(dept.deptno, '30', 'c00', '000') highlight The link column now passes the MGR ID and the HIGHLIGHT colour (red when the condition is satisfied and black when it is not).
I created another hidden and protected page item <tt>P0_HIGHLIGHT</tt> as the target for the highlight value, and used the Pre/Post Element Text properties of the <tt>P0_G_MGR</tt> to wrap it in a <tt>span</tt> whose colour is changed using the <tt>P0_HIGHLIGHT</tt> value as a subtitution string:
Having done that, I still don't really get the requirement here. I'm sure that given the full picture I'd be using a completely different approach...

How to handle special characters in Stage web view with Load URL method?

Hi,
I have Latin special characters in my text. My HTML content contains the text as well as the image. If I use stage webview LoadString, images will not be displayed. But my latin characters are displayed correctly.
If I use LoadURL method, the images are displayed correctly but I have problem in displaying the latin special characters. How to solve this issue?

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 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.

How to handle special characters in SQL statements

How do you handle special charactes in a SQL statement? Here is an example:
update table
set notefield = 'This is Waldo's note'
where keyfield = 7;
Because the database connectivity vi accepts a string datatype wire, the ' in Waldo's note is seen as the end of string and an error is generated.
Is there a way to tell labview that the ' is part of the string and not the string delimiter?
Waldo

If two single quotes don't work, try backslash single quote, like \'
The backslash is often used as an escape character, meaning to treat the next character literally.

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 metadata?

I have an implementation in C# to call ACS webservices for a long time. Last week we realized that some special characters in metadata fields are making the package request to not work. Example characters: éë. The response from ACS contains E_ADEPT_DISTRIBUTOR_AUTH. If we remove the special character, the request works as expected.
I know that characters are working in the jar application but we can't manage to make them work from our C# application.
Any help is welcome.

Doing a SHA1-HMAC is relatively simple and there are only two inputs, the key and the message.
Since you say this works correctly with lower ascii characters, but not with Unicode characters then I would assume you have the key correct and the only thing that is different is the message. Also since it works correctly with lower ascii characters then you have the XML infoset serialization correct, so assuming a similiarly sized message (ie take one character and replace with a unicode character), then your problem is going to be in the character encoding.
I would suggest some healthy paranoia about this, by verifying that the byte stream being hashed is indeed correctly UTF8 encoded by looking at the hex values (breakpoint in the SHA1-HMAC code) and comparing to a UTF8 table such as http://www.utf8-chartable.de.

FTP ADAPTER: How to handle Special characters

Hi All,
We are running into issues with special characters while fpt'ing the file using FTP adapter.
ex: japanese characters '東邦チタニウム株式会社' would look as '???????????' in the transferred file.
The following steps are involved in the process.
1. Reads the data from a database.
2. Constructs an XML object.
3. Transforms the data into ftp msg.- In this step the spl. characters are fine
4. FTP's the msg.
5. The file on FTP server has issues.
Tried to change the file type to binary, UTF-8 etc.. but nothing worked.
Any help/pointers will be highly appreciated.
Thanks in advance.

Hi,
Any suggestions?Yes, please provide some details regarding:
the PL/SQL procedureWhat is it, what is it meant to do?
the thing fails. How does it fail?
Always post a complete error message when 'it fails'.
Also provide your DB-version as well
(and ideally you'd top it off with an example).
From what I can make of it you're trying to process some in-list that fails when you're passing more than one value?

How to handle special characters in unix

I have to implement a requirement where I construct a string separated by a special character, encrypt it and send it over to an external site. The program worked fine on my local machine (WL 9.2, JDK 5.0 on Windows). However, when moved to unix, the special character turned into ?. I searched and tried quite a lot of things but didnt find a solution. Has anybody encountered and resolved this issue?

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.
Cheers,
Chris

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.

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!
Arvind Patil - IN

Monica--
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.
