Special characters in java, oracle and html

Hi,
I'm working on a mini content management system and need help with dealing with special characters.
The input are taken from html form which are then stored into a varchar column in oracle database.
When i retrieve the data, some of the special characters have been changed to ??? and also
fields with double quote are modified.
I believe there two issues;
1. dealing with special characters
2. display special characters back in html form textfield after retrieving.
e.g.
This is the line with "quote" saved to database
This is the line with "quote" retrieved from database
This is the line with displayed in html text field.
Any help will be much appreciated.
Thanks in advance.

Maybe you should try this couple of classes: java.net.URLDecoder and java.net.URLEncoder

Special characters in joins name and Identifiers

I am working on a business area which was created a time ago. Joins name contain special characters. Regarding Oracle, these are not going to be accepted in the new versions.
How can I fix this problem, knowing any change in joins name will affect the workbooks.

You can - and should - double check this, but I believe changing the name only of the join will not cause a problem per se.
It's when you change the name AND the identifier in one fell swoop that a problem will occur.
That's because when Disco opens up a workbook, it will look for the name OR identifier (if, for example, the name was changed).
So, in theory, you could change the name of a join, folder, etc. and then open all your Discoverer workbooks and then save them again. Now they will have knowledge of the new name.
Then if you wanted - and ALL workbooks were already run and re-saved - you could change the identifier and do the whole process over again.
So, to summarize, I believe that just changing the actual join name ONLY will not cause any problem.

I went to import special characters in imovie '11 and now the character window comes up on every application, yet won't open in iMovie at all, it flashes across every screen on each key/mouse click

I went to import special characters in imovie '11 and now the character window comes up on every application, yet won't open in iMovie at all, it flashes across every screen on each key/mouse click, stops the other software from running, and won't shut off, ever.

Try trashing the .plist in Home/Library/Preferences which has CharacterPalette in its name.

Special characters in file names and directories

I'm building a site that lets users create directories to
which they give the name they want.
Using PHP, is there one universal solution to avoid any
special characters in directories, yet will
display the directory/file names in html the way the user
intended?
example of a possible name:
"ça alors: it's a déjà-vu"
How can I encode this so it's valid as a directory name, yet
can be displayed as intended when the
name is output to the page. urlencode() does not do the job,
neither does htmlentities()...

PS: basically it's not a url encoding issue.
I can url encode "ça alors: it's a déjà-vu",
and pass it in a url query string. But my issue is not
with an url query string, it's with an actual URL, that is,
the actual name of the directory. It
can't be "ça alors: it's a déjà-vu". But I
want to allow the user to name their directory like that
if they want. So I need a way to encode this into characters
that can be used for an actual
directory on the server.

Special Characters in search terms and in data

I'm having a hard time making a decision about what types of special characters I should support in my Contains search.
I know that some of my data has dashes in it like '1034-AMFM' but if a user puts that in the search term it will be interpretted as a special character by OracleText correct?
What I have resorted to at the moment is stripping all special characters out of the users search terms but this severely limits the capabilities of Oracle Text and what I'm stuck with is a very basic search tool.
Is there a way to find a happy medium here?

You need to use a backslash, not a forward slash. The following demonstrates the behavior under different circumstances, such as specifying the hyphen as a printjoin or skipjoin or whitespace, which is the default, with and without escaping:
SCOTT@10gXE> CREATE TABLE test_tab (test_col VARCHAR2 (30))

Special Characters issue in DEV and QAS

Hi,
I am uploading a file that has special characters (Japanese).
In the DEV system the special character is converted to #. Which the business wants.
In QAS system the special character is not converted and is as it is, which makes the business users difficult to find out if any speical characters are there and they don't want the special character as it is
The file consists millions of record with a possibility of four or five records with special characters
The special characters on keyboards is not an issue.
The programs in DEV and QAS system are same and the file tested is also the same but different results.
Tried in Tcode SNLS to find something but didn't know what and where to look into.
What could be the issue in this? Looks like this is Basis issue but would like to know if anyone can let me know.......
Regards
Sandeep

Hi ,
i want to check ur open dataset statement in the program which is being used here if at all in ur case.
Can you please check the relavant code page in both the D and Q systems and search with the appropriate hexa decimal values(for the special characters ) in both the systems ..
u can use code page by tcode scp ..
ex -> as u say a special char sp1 is having entry in q and code page which is being used (like 4200 )
is not having in d03 .
then if in d03 this page has no entry then it shows as # , since it is showing in q then it has an entry over there. this is my guess..
so if at all the client wants not to see this special char's , u need to remove them from this code page.. and check ..
Cant say if this can solve but u can take this as one more way of dealing with code pages and special chars....
br vijay..

Remove all the special characters using java.util.regex

Hi,
How to remove the all the special characters in a String[] using regex, i have the following:-
public class RegExpTest {
     private static String removeSplCharactersForNumber(String[] number) {
          String number= null;
          Matcher m = null;
               Pattern p = Pattern.compile("\\!\\@\\#\\$\\%\\^\\&\\*\$\$\\_\\+\\-\\{\\}\\|\\;\\\\\\'////\\,\\.\\?\\<\\>\\[\\]");
               for (int i = 0; i < number.length; i++) {
               m = p.matcher(number);
               if (m.find()) {
                    number= m.replaceAll("");
               System.out.println("Final Number is:::"+number);
               return number;
          public static void main(String args[]){
               String[] str = {"raghav!@#$%^&*()_+"};
               RegExpTest regExpTest = new RegExpTest();
               regExpTest.removeSplCharactersForNumber(str);
This code is not working and m.find() is "false", here i want the output to be raghav for the entered string array, not only that it should remove all the special characters for a entered string[]. Is there a simple way to do this to remove all the special characters for a given string[]? More importantly the "spaces" (treated as a spl. character), should be removed as well. Please do provide a solution to this.
Thanks

You don't need the find(). Just use the replaceAll() on each element of the String[] i.e.
String[] values = ...
for (int i = 0; i < values.length; i++)
    values[i] = p.matcher(values).replaceAll("");
}I can't understand your regex since the forum software has mangled it but you just need to add a space to the set of chars to remove. When you post code, surround it with CODE tags then the forum software won't mangle it.

Java, Oracle, and Arabic Characters

Hi,
I need to run some Forms fmb files that contain Arabic characters through Oracle's forms to xml converter (frmf2xml.bat). The XML that is generated by the utility contains strings such as "Ø±Ù‚Ù… Ø§Ù„Ù…ÙˆØ¸Ù�" instead of the Arabic characters I was expecting.
The XML output by frmf2xml.bat is encoded as UTF-8.
My NLS_LANG is set to AMERICAN_AMERICA.UTF8. The characters display fine in Forms Builder.
Is there another localization setting I need to make with the conversion utility or even with Java itself?
Any insight or comments appreciated.
Dave

On a related note, I am seeing a couple of different types of 'incorrect' characters based on different NLS_LANG settings.
If it is set to AMERICAN_AMERICA.UTF8, I get characters like this:
Ø±Ù‚Ù… Ø§Ù„Ù…ÙˆØ¸Ù�
If it is set to ARABIC_UNITED ARAB EMIRATES.AR8MSWIN1256, I get characters like this:
ÑÞã ÇáãæÙÝ
Do any of you know what these characters are?
Thanks for any insight.

Diff between Java,Window and HTML Clients

Hi can any body clear me
what is the difference between
1. JAVA Client
2. Windows Client
3. HTML Client.
regards
mmukesh

The Windows client requires SAPGUI for Windows loaded on the dekstop (400+ MB of disk), but it works most efficiently.
The HTML client requires an ITS and is not as efficient, but need no specialized software on the desktop.
The Java client is almost never used except by Mac and Unix users!
Cheers
try searching SDN for SAPGUI variants for more details

Replace special characters in xml to its HTML equivalent

Hello All,
I did a small xml processor which will parse the given xml document and retrieves the necessary values. I used XPath with DocumentBuilder to implement the same.
The problem which had faced initially was, i could not able parse the document when the value comes with the '&' special character. For example,
<description>a & b</description>I did some analysis and found that the '&' should be replaced with its corresponding HTML equivalent
& So the problem had solved and i was able to process the xml document as expected. I used the replaceAll() method to the entire document.
Then i thought, there would be some other special character which may cause the same error in future. I found '<' is also will cause the same kind of error. For example,
<description>a < b</description>Here i couldn't able to use the replaceAll(), because even the '<' in the xml element tags was replaced. So i was not able to parse the xml document.
Did anyone face this kind of issue? Can anyone help me to get rid of this issue.
Thanks
kms

Thats the thing about XML. It has to be correct, or it doesn't pass the gate. This is nothing really, seen it many times before. It becomes funny when you start to run into character set mismatches.
In this case the XML data should have either been escaped already, or the data should have been wrapped in cdata blocks, as described here:
http://www.w3schools.com/xml/xml_cdata.asp
Manually "fixing" files is not what you want to be doing. The file has to be correct according to the very simple yet strict XML specifications, or it isn't accepted.
