Character encoding form input

Hi
          Using WebLogic 6.1.
          I have a JSP containing a HTML form with some input fields. The user
          should be able to edit non-ASCII characters input fields. If he does
          that now, I will retrieve some kind for encoding of the non-ASCII
          characters when I use request.getParameter("..."); on the server.
          I want to use UTF-8 all the way from client to the
          request.getParameter("..."); call. What do I do?
          I have setup the following:
          <% response.setContentType("text/html; charset=utf-8"); %> in my JSP.
          <meta http-equiv="content-type" content="text/html; charset=utf-8"> in
          the head in my JSP.
          <input-charset>
          <resource-path>*</resource-path>
          <java-charset-name>UTF-8</java-charset-name>
          </input-charset>
          in my weblogic.xml.
          Why do I not se the correct characters when using
          request.getParameter("...");
          Kind Regards

Try this one:
          <input-charset>
          <resource-path>/*</resource-path>
          <java-charset-name>UTF-8</java-charset-name>
          </input-charset>

Character Encoding in Input Processor

hi,
I am running Portal 4.0. I am using the <portlet:form> tag to create a
formular. I send the data to an Input Processor. The IP grabs the parameter
with request.getParameter("xyz"). Inside the IP the character encoding does
not work. I need support for the german "umlaute". Theses characters are not
displayed properly. Hoc can I set the character encoding inside of the IP?
Regards
Michael

on the form processing page, you probably need to call request.setCharacterEncoding("UTF-8") (or whatever encoding you're using) before reading any values.

Problems with Forms and character encoding

I'm having problems trying to read unicode data inputted into a Form on my JSP page.
I've used the meta tag <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> to set the charset of the page to UTF-8. I've inputted some chinese characters inot my form and when I try to read the subsequent request parameter in my servlet using request.getParameter() the string returned is this
"来源" which is the escape sequence required by HTML to display these characters.
From what I've read on the subject this doesn't seem like the expected value. I've tried other ways of getting the correct string value such as setting the character encoding request.setCharacterEncoding("UTF-8") and then converting the bytes using this encoding value but it doesn't seem to work.
I could write a method to split up the string using the ; as a token and working out the correct unicode character but this doesn't seem like the right thing to do.
Any help on how to pass the correct information from the Form in the JSP page to the servlet would be greatly appreciated

I don't believe that is correct, but if it's returning HTML escapes instead of URL Encoded characters, then it's the browser doing it. This is my test page for playing with Chinese...

Using Direct Input mode: UTF-8 character encoding assumed

When I validate a web page in dreamweaver CS5 (using Jeffrey Zeldman's Web Standards Advisor ) I receive the following warning; Using Direct Input mode: UTF-8 character encoding assumed.
However if I validate using W3C either as a file upload or via the live site the page validates correctly.
Can anybody please help, as it is driving me insane.

Hi John
Thank you for your swift response,
As I said before this only happens locally within Dreamweaver CS5.
However The web address is www.countryimage.co.uk/index.htm
As you will see from the code I have included <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> within the head

Character Encoding for JSPs and HTML forms

After having read loads of postings on character encoding problems I'm still puzzled about the following problem:
I have an instance (A) of WL 8.1 SP3 on a WinXP machine and another instance (B) of WL 8.1 without any SP on a Win2K machine. The underlying Windows locale is english(US) in both cases.
The same application deployed as a war file to these instances does not behave in the same way when it comes to displaying non-Latin1-characters like the Euro symbol: Whereas (A) shows and accepts these characters as request-parameters, (B) does not.
Since the war file is the same (weblogic.xml, jsps and everything), the reason for this must either be the service-pack-level or some other configuration setting I overlooked.
Any hints are appreciated!

Try this:
Prefrences -> Content -> Fonts & Color -> Advanced
At the bottom, choose your Encoding.

How can I tell what character encoding is sent from the browser?

Hi,
I am developing a servlet which supposed to be used to send and receive message
in multiple character set. However, I read from the previous postings that each
Weblogic Server can only support one input character encoding. Is that true?
And do you have any suggestions on how I can do what I want. For example, I
have a HTML form for people to post any comments (they may post in any characterset,
like ShiftJIS, Big5, Gb, etc). I need to know what character encoding they are
using before I can read that correctly in the servlet and save in the database.

From what I understand (I haven't used it yet) 6.1 supports the 2.3
servlet spec. That should have a method to set the encoding.
Otherwise, I don't think you can support multiple encodings in one
instance of WebLogic.
From what I know browsers don't give any indication at all about what
encoding they're using. I've read some chatter about the HTTP spec
being changed so it's always UTF-8, but that's a Some Day(TM) kind of
thing, so you're stuck with all the stuff out there now which doesn't do
everything in UTF-8.
Sorry for the bad news, but if it makes you feel any better I've felt
your pain. Oh, and trying to process multipart/form-data (file upload)
forms is even worse and from what I've seen the API that people talk
about on these newsgroups assumes everything is ISO-8859-1.

Wrong character encoding from flash to mysql

Hi, im experiencing problems with character encoding not
functioning correctly when sending from flash to mysql. What i am
doing is doing a contact form in flash which then sends the value
to a php file which takes the values and inserts them into a table.
As i'm using icelandic charecters i need the char encoding to be
either latin1 or utf8 in mysql, or at least i think so. But it
seems that flash or the php document isn't sending in the same
format as i have selected in mysql because all special icelandic
characters come scrambled in the mysql table. Firefox tells me
tough that the html document containing the flash movie is using
utf-8.

I don't know anything about Icelandic characters, but Flash
generally really likes UTF-8. So it should be sending that if that
is what it is starting with.
You aren't using any kind of useCodePage? That will mess it
up.
Are you sure that the input method is Icelandic?
In the testing environment can you list variables (from the
debug menu) and see if they look proper? If they do then Flash is
readying them correctly and the problem must be coming in further
down stream.

XML parser not detecting character encoding

Hi,
I am using Jdeveloper 9.0.5 preview and the same problem is happening in our production AS 9.0.2 release.
The character encoding of an xml document is not correctly being detected by the oracle v2 parser even though the xml declaration correctly contains
<?xml version="1.0" encoding="ISO-8859-1" ?>
instead it treats the document as UTF8 encoding which is fine until a document comes along with an extended character which then causes a
java.io.UTFDataFormatException: Invalid UTF8 encoding.
at oracle.xml.parser.v2.XMLUTF8Reader.checkUTF8Byte(XMLUTF8Reader.java:160)
at oracle.xml.parser.v2.XMLUTF8Reader.readUTF8Char(XMLUTF8Reader.java:187)
at oracle.xml.parser.v2.XMLUTF8Reader.fillBuffer(XMLUTF8Reader.java:120)
at oracle.xml.parser.v2.XMLByteReader.saveBuffer(XMLByteReader.java:448)
at oracle.xml.parser.v2.XMLReader.fillBuffer(XMLReader.java:2023)
at oracle.xml.parser.v2.XMLReader.tryRead(XMLReader.java:972)
at oracle.xml.parser.v2.XMLReader.scanXMLDecl(XMLReader.java:2589)

at oracle.xml.parser.v2.XMLReader.pushXMLReader(XMLReader.java:192)
at oracle.xml.parser.v2.XMLParser.parse(XMLParser.java:144)
as you can see it is explicitly casting the XMLUTF8Reader to perform the read.
I can get around this by hard coding the xml input stream to be processed by a reader
XMLSource = new StreamSource(new InputStreamReader(XMLInStream,"ISO-8859-1"));
however the manual documents that the character encoding is automatically picked up from the xml file and casting into a reader is not necessary, so I should be able to write
XMLSource = new StreamSource(XMLInStream)
Does anyone else experience this same problem?
having to hardcode the encoding causes my software to lose flexibility.
Jarrod Sharp.

An XML document should be created with 'ISO-8859-1' encoding to be parsed as 'ISO-8859-1' encoding.

Character encoding again

Hi, i havent got any answer so i try to ask again...
I have created a page from Data Controls.
I have created parameter form. And table. Detail is showed at the bottom of page (there is shown current row through #bindings. . .
Everything works fine when i fill something into parameter form table is filtered by that criteria, when current row is changed, the detail is also changed. But when i fill some czech character into parametr form it works pretty bad.
The table is correctly filtered but when i make any other action after filtering, the table shows no rows.
I found what cause this problem. It is the Property in bindings that holds value for this parameter. When i first call bindings.findXXX.execute the Propertys value is "č" for example. That is correct and table shows filtered rows. After i perform another action (i think it is not dependent what the action is, but change current row fow example) the value in that Property has changed to "?" instead of "č" and because of this filter is applied again and table shows no rows. I have checked all encoding and character encoding is set to utf-8. Is this the problem and i miss some settings ?
1) menu tools-preferences-Environment
2) project properties- compiler-character encoding
3) in jspx
<?xml version='1.0' encoding='UTF-8'?>
<jsp:directive.page contentType="text/html;charset=UTF-8"
pageEncoding="UTF-8"/>
<afh:head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
</afh:head>
is there other ? i dont know i set this settings long ago ...
Please if someone know, give me some hint , thanks for help.
Jdeveloper 10.1.3.0.4(SU5)

check regional language settings on your machiner where u r application server is running. I faced this problem but was able to resolve by modifying the
NLS_LANG = AMERICAN_AMERICA.WE8ISO8859P1
NLS_LANG is under HKEY_LOCAL_MACHINE==>ORACLE
WE8ISO8859P1 is the standard encoding for my application developed in local indian language and works fine for me

Character encoding conversion for marshall/unmarshall?

Hello, Java Web Services gurus,
I am wondering if there is an easy/plugin-able way to do character encoding conversion transparently in the process of marshall/unmarshall.
Basically, my input/output will always be these UTF-8 XMLs. As the backend database is ISO encoded, I hope the result of unmarshall will give me ISO strings. And when it comes to marshall, the ISO strings can be transparently turned to UTF-8 XML response. Right now I'm using JAXB's annotations to parse XML into objects.
I understand there will be chars in the input file not able to get converted, if so, I'd be be expecting an error/exception that flags the failure
Hope I sound clear. This has been a headache for a while. Really hope someone may help out a bit. Thanks a million in advance

Character Encoding in XML

Hello All,
I am not clear about solving the problem.
We have a Java application on NT that is supposed to communicate with the same application on MVS mainframe through XML.
We have a character encoding for these XML commands we send for communication.
The problem is, on MVS the parser is not understaning the US-ASCII character encoding. And so we are getting the infamous "illegal character error".
The main frame file.encoding=CP1047 and
NT's file.encoding = us-ascii.
Is there any character encoding that is common to these two machines: mainframe and NT.
IF it is Unicode, what is the correct notation for it.
Or is there any way for specifying the parsers to which character encoding should be used.
thanks,
Sridhar

On the mainframe end maybe something like-
FileInputStream fris = new FileInputStream("C:\\whatever.xml");
InputStreamReader is= new InputStreamReader(fris, "ASCII");//or maybe "us-ascii" "US-ASCII"
BufferedReader brin = new BufferedReader(is);
Or give inputstream/buffered reader to whatever application you are using to parse the xml. The input stream reader should allow you to set your encoding even if the system doesnt have the native encoding. Depends though on which/whose jvm using you are using jdk1.2 at least supports following on this page http://as400bks.rochester.ibm.com/pubs/html/as400/v4r4/ic2924/info/java/rzaha/javaapi/intl/encoding.doc.html

Detecting character encoding from BLOB stream... (PLSQL)

I'am looking for a procedure/function which can return me the character encoding of a "text/xml/csv/slk" file stored in BLOB..
For example...
I have 4 files in different encodings (UTF8, Utf8BOM, ISO8859_2, Windows1252)...
With java I'can simply detect the character encoding with JuniversalCharDet (http://code.google.com/p/juniversalchardet/)...
thank you

Solved...
On my local PC I have installed Java 1.5.0_00 (because on DB is 1.5.0_10)...
With Jdeveloper I have recompiled source code from:
http://juniversalchardet.googlecode.com/svn/trunk/src/org/mozilla/universalchardet
http://code.google.com/p/juniversalchardet/
After that I have made a JAR file and uploaded it with loadjava to my database...
C:\>loadjava -grant r_inis_prod -force -schema insurance2 -verbose -thin -user username/password@ip:port:sid chardet.jarAfter that I have done a java procedure and PLSQL wrapper example below:
   public static String verifyEncoding(BLOB p_blob) {
       if (p_blob == null) return "-1";
       try
        InputStream is = new BufferedInputStream(p_blob.getBinaryStream());
        UniversalDetector detector = new UniversalDetector(null);
        byte[] buf = new byte[p_blob.getChunkSize()];
        int nread;
        while ((nread = is.read(buf)) > 0 && !detector.isDone()) {
            detector.handleData(buf, 0, nread);
        detector.dataEnd();
        is.close();
       return detector.getDetectedCharset();
       catch(Exception ex) {
           return "-2";
   }as you can see I used -2 for exception and -1 if input blob is null.
then i have made a PLSQL procedure:
function f_preveri_encoding(p_blob in blob) return varchar2 is
language Java name 'Zip.Zip.verifyEncoding(oracle.sql.BLOB) return java.lang.String';After that I have uploaded 2 different txt files in my blob field.. (first one is encoded with UTF-8, second one with WINDOWS-1252)..
example how to call:
declare
   l_blob blob;
   l_encoding varchar2(100);
begin
select vsebina into l_blob from dok_vsebina_dokumenta_blob where id = 401587359 ;
l_encoding := zip_util.f_preveri_encoding(l_blob);
if l_encoding = 'UTF-8' then
   dbms_output.put_line('file is encoded with UTF-8');
elsif l_encoding = 'WINDOWS-1252' then
   dbms_output.put_line('file is encoded with WINDOWS-1252');
else
    dbms_output.put_line('other enc...');
end if;
end;Now I can get encoding from blob and convert it to database encoding and store datas in CLOB field..
Here you have a chardet.jar file if you need this functionality..

Character encoding in portlets

Hi
I was developed Java portlets, using JPS and BC4J.
We are using portal (9.0.2) in different languages (English, Hungarian).
In JPS pages wich character encoding do I use, because the data retreived from the database doesn't appear properly.
thanks

on the form processing page, you probably need to call request.setCharacterEncoding("UTF-8") (or whatever encoding you're using) before reading any values.

Character encoding in JSP

hi all.
my problem is about character encoding in JSP.
my project is based on struts framework & mysql database. as a servlet container i have the Tomcat absolutely.
i have correctly set the mysql db. when i insert data by hand, usin' INSERT INTO bla bla, it works with Turkish Characters.
After that, i have checked, my jsp page correctly loads data from db and displays on browser. all the special Turkish characters appears well.
The problem starts with posting!
I want some data from the user, and i have simple wysiwyg javascript editor. the editor correctly process the text, after posting data and saving into db, some how it corrupts.
(whatever, i have tried it with a simple textarea, it does not work)
simply my problem is: the data somehow corrupts while it is being posted.
thanx.

Over-riding Character encoding in JSP

I have JSP which was precompiled under weblogic with no encoding.I want to change the encoding during run time using response or request Object.I am using filters before JSP's so the response encoding is not getting to JSP even though i try to set in the response by
          response.setContentType("text/html;SJIS") it is getting lost.So i tried to set in the request as an attribute and retreived in the JSP page directive.It did not work.
          The browser is not detecting my character encoding why?.Is there anything called static encoding from weblogic that is causing problem?.If it is, how would I turn off the static encoding from the weblogic programmatically in JSP so that browser detects correct encoding in the page directive dynamically.I even tried
          request.setCharacterEncoding("SJIS") which is japenese but it did not work.Any help would be appreciated.The encoding it shows in the browser by default is "UTF-8" even i though i send "SJIS" encoding in the request
