UnsupportedEncodingException
I have written a simple servlet to read the contents of an http request and print it out. The request contains a soap message, but I am not parsing it in this servlet, simply printing the request contents out. I am using iPlanet Web Server 6.0. When my servlet tries to do request.getReader() I get:
java.io.UnsupportedEncodingException - UTF-8
With trace I can see the contents of the request being sent:
Client Data, POST /missingkids/servlet/SimpleSoapHttpReceiveServlet HTTP/1.1
SOAPAction: "uri:SoapHttpReceiveServlet"
Content-Type: text/xml; charset="UTF-8"
User-Agent: SOAP Toolkit 3.0

My servlet code:
if(request.getContentLength() > 0)
try{
java.io.BufferedReader reader = request.getReader();
String line = null;
while((line = reader.readLine()) != null)
System.out.println(line);
catch(Exception e)
System.out.println(e);
Any ideas why I get this error? Thanks.
Try not putting the quotes around UTF-8.

Problem with file download in oracle portal:UnsupportedEncodingException
Hi,
I'm developing a struts application inside Oracle Portal, when i click on a
action link i need to download a file.
<pdk-struts-html:link action="/fileDownload2Action?file=myfile.txt">Click Here to See the PDF</pdk-struts-html:link>
i've tried to use org.apache.struts.actions.DownloadAction as follows:
public class MyExampleFileDownload extends DownloadAction{
protected StreamInfo getStreamInfo(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
// File Name
String fileName = mapping.getParameter();
// Set the content disposition
response.setHeader("Content-disposition",
"attachment; filename=" + fileName);
// Download a "pdf" file - gets the file name from the
// Action Mapping's parameter
String contentType = "application/pdf";
File file = new File(fileName);
return new FileStreamInfo(contentType, file);
but on the forward i receive the following exception:
received IOException

so it seems that struts forward in oracle have to be only text/html files
but i don't wanto to go tio another page, just download a file on the same page
after some control in my action.
Could you suggest me any alternative solution?

Java.io.UnsupportedEncodingException
Hello.
I am trying to parse an XML file into its DOM representation. The XML files starts with this line:
<?xml version="1.0" encoding="X-User-Defined"?>My code for parsing the XML is this:
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
builder = factory.newDocumentBuilder();
Document doc = builder.parse(file);When run, I get this:
java.io.UnsupportedEncodingException: X-User-DefinedSo the problem is with the encoding of the XML file as specified. I'd like to know if there is a way to make the parser simply ignore the encoding attribute of the XML header. Or alternatively, treat it as an encoding that is supported.
Thanks.
-NSThank you. That worked.
I implemented a custom CharsetProvider and installed it per the instructions in the javadoc. I'll provide the implementation for future reference:
import java.nio.charset.Charset;
import java.nio.charset.spi.CharsetProvider;
import java.util.Iterator;
public class UserDefinedCharsetProvider extends CharsetProvider {
public Iterator<Charset> charsets() {
return null;
public Charset charsetForName(String charsetName) {
return Charset.forName("UTF-8");

I had similar problems when I had to read e-mail messages encoded in UTF-7, which apparently is not uncommon in e-mail but still not supported by Java. So I had code like this:ContentType ct = new ContentType(p.getContentType());
String charset = ct.getParameter("charset");
Object o = null;
// If the charset is UTF-7, call the method for converting the bytes to a String.
// We have to do this because UTF-7 isn't a supported charset in Java.
if ("UTF-7".equalsIgnoreCase(charset) || "UNICODE-1-1-UTF-7".equalsIgnoreCase(charset)) {
InputStream in = p.getInputStream();
ByteArrayOutputStream out = new ByteArrayOutputStream();
int c;
while ((c = in.read()) != -1) {
out.write(c);
ByteToCharUTF7 btc = new ByteToCharUTF7();
byte[] bytes = out.toByteArray();
char[] chars = new char[bytes.length];
int realLength = btc.convert(bytes, 0, bytes.length, chars, 0, chars.length);
o = new String(chars, 0, realLength);
} else {
o = p.getContent();
}Where that ByteToCharUTF7 is a class that extends sun.io.ByteToCharConverter and overrides a method whose signature ispublic int convert(
byte[] bytes, int byteStart, int byteEnd, char[] chars, int charStart, int charEnd)
throws sun.io.ConversionBufferFullException, sun.io.UnknownCharacterExceptionThe purpose of that method is to take an array of bytes and decode it to an array of chars, using (in your case) the rules for decoding KOI8-U. You would have to write that yourself, but if they are similar to the rules for KOI8-R then perhaps you could use KOI8-R to help you.
I believe that in Java 5 there is a way to insert new charsets into the system, so if you are using Java 5 then you should investigate that. You would still have to write the charset decoder yourself, though, as Java 5 still doesn't support KOI8-U. Unless you can find it already done on the Internet. -

Francesco RizzelloHi,
I have done everything as mentioned by various web sites to develop a pdk-struts form, my java code compiles, the jsps compiles everything compiles correctly, and the portal shows up.
I also put a HTML form in it.
When a I deploy I can see and work with the HTML form but the portal is not recogniziing the pdk-struts tags, though I made the pdk-struts-html.tld part of the WEB-INF/ yet it wont show up the pdk-struts form.
Any help regarding this will be highly appreciated.

Please help me out.
Thanks in advance,
VenkatHi,
What version of the driver are you using? The "OALL8 is in an inconsistent state" exception usually indicates a problem in the protocol. When this exception occurs the protocol is broken and the connection can't be used anymore. I would suggest that you try using the 11.2.0.1 JDBC driver that you can download from:
http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/index.html

Java.io.UnsupportedEncodingException: EUC-JP on Windows
Hi,
I've developed a Java class that works on a web page containing Japanese characters, but I have two different behavior on MacOSX and Windows.
On MacOSX: I can see CORRECTLY characters both on a Swing Component and on a temporary file written by my Java class and opened with a browser.
On Windows: When I run my class I obtain the following error
java.io.UnsupportedEncodingException: EUC-JP
at sun.nio.cs.StreamDecoder.forInputStreamReader(Unknown Source)
at java.io.InputStreamReader.<init>(Unknown Source)Why???
Thanks in advance.
ElisaThat message isn't saying EUC-JP is the wrong encoding, it's saying it can't find an encoding called "EUC-JP". Try running this code: import java.util.*;
import java.nio.charset.*;
public class Test
public static void main(String[] args) throws Exception
SortedMap<String, Charset> cs = Charset.availableCharsets();
System.out.printf("%d charsets:%n", cs.size());
for (String s : cs.keySet())
System.out.println(s);
} I get 162 names, the third one being "EUC-JP". (WinXP SP3, JDK 1.6.0_12) -
UnsupportedEncodingException ERROR help me
i'm working with a mail system.i got a mail object from other system,when i use Object.toString();
the method throw a Exception:java.io.UnsupportedEncodingException: gbk
then i found that java only can recognise charset 'GBK', but not charset 'gbk',
then some other system can read this mail, and can recognise 'gbk'.
so i want to know how to make a alias gbk for GBK? who can help me very thanks.
this error occur in following progress:
MimeMessage m;
Part p = (Part)m
Object o = (Object)p.getConetent();
then
String content = o.toString();
this "Object.toString();" will throw java.io.UnsupportedEncodingException: gbk
so i think extent Object class maybe can work, anyone know more about this?Could you try encoding as gbk and then if it fails (ie in the catch() statement) try encoding as GBK?

UnsupportedEncodingException in JRE only and not with SDK
Hi,
I am running my Java program as a application in Win NT run time environment and the app uses JConnect 5.2 as its JDBC driver. JDBC connection is succesful but a query fails for the "UnsupportedEncodingException" error listed below. I don't get the same error if I use SDK version of Java.exe but I get the error only with the java.exe of the JRE.
What is different in the Run time environment. Any solutions?
Error: java.sql.SQLException: JZ006: Caught IOException:
java.io.IOException: JZ0I6: An error occured converting UNICODE to the
charset used by the server. Error message: java.io.CharConversionException:
java.io.UnsupportedEncodingException: Cp437
Thanks,
BalaMy guess is that you use the US English version of the JRE which only have the basic encodings. If you use the International version, it should work. Check
http://java.sun.com/j2se/1.3.0/docs/guide/intl/encoding.doc.html -
Re UnsupportedEncodingException
Hi All,
I am trying to create an object of OutputStreamWriter, passing charsetName as ISO-2022, which results in UnsupportedEncodingException. If I use UTF-8 it works fine. Please refer to following abstract from JDK documentation:
public OutputStreamWriter(OutputStream out,
String charsetName)
throws UnsupportedEncodingException
Create an OutputStreamWriter that uses the named charset.
Parameters:
out - An OutputStream
charsetName - The name of a supported charset
Throws:
UnsupportedEncodingException - If the named encoding is not supported
I am not clear with what they meant by the named encoding is not supported. Do they refer the underlying system or are they refering to JDK. I have tried using JDK 1.3, and 1.4.1 also. The problem persists in both case. It looks like the named encoding is not supported by underlying machine. Am I right here? Please correct me if I am wrong.
If that be the case, how can we get list of supported encoding of system where java application is running.
Pls. reply asap as this is related to an urgent issue.
Thanks in advance.It's probably an issue of your current Java Runtime Environment. As the documentation of the java.lang package states:
Every implementation of the Java platform is required to support the following character encodings. Consult the release documentation for your implementation to see if any other encodings are supported.
US-ASCII, ISO-8859-1, UTF-8, UTF-16BE, UTF-16LE, UTF-16
I don't know to which country/region your charset belongs, but perhaps you can try to download a localized runtime environment for this country/region (chinese, turkish, ...).
Hope this helps,

UnsupportedEncodingException in JSPs
Environment
===========
IAS6.0SP3
iPlanet webserver 6.0sp1
Problem
========
I have a JSP with code as follows
<% response.setHeader("Content-Type", "text/html; charset=" +
Configuration.JSP_CONTENTTYPE_CHARSET); %>
<%@ page errorPage="/errorpage.jsp" %>
<%@ taglib uri="/WEB-INF/elms.tld" prefix="elms" %>
This gives compilation error as shown at the end of the mail.
If the JSP is modified to
<%@ page errorPage="/errorpage.jsp" %>
<%@ taglib uri="/WEB-INF/elms.tld" prefix="elms" %>
<% response.setHeader("Content-Type", "text/html; charset=" +
Configuration.JSP_CONTENTTYPE_CHARSET); %>
It works fine. Is there any reason for this behaviour.

Thanks
ChanduThis problem is solved. Hope this solution may help others.
Problem
========
This line of code works fine in Weblogic, Websphere and JBoss
but gives problem in iPlanet.
<% response.setHeader("Content-Type", "text/html; charset=" +
> Configuration.JSP_CONTENTTYPE_CHARSET); %>
Solution
========
This is because of the smaller case "charset".
When modified to
<% response.setHeader("Content-Type", "text/html; CHARSET=" +
> Configuration.JSP_CONTENTTYPE_CHARSET); %>
it works fine.
Piece of advice on ias development
- Do not get carried away by the "error". The error messages are very
misleading, like the SC_NOT_FOUND error and this.
This happens

iPlanet webserver 6.0sp1
Problem
========
I have a JSP with code as follows
<% response.setHeader("Content-Type", "text/html; charset=" +
Configuration.JSP_CONTENTTYPE_CHARSET); %>
<%@ page errorPage="/errorpage.jsp" %>
<%@ taglib uri="/WEB-INF/elms.tld" prefix="elms" %>
This gives compilation error as shown at the end of the mail.
If the JSP is modified to
<%@ page errorPage="/errorpage.jsp" %>
<%@ taglib uri="/WEB-INF/elms.tld" prefix="elms" %>
<% response.setHeader("Content-Type", "text/html; charset=" +
Configuration.JSP_CONTENTTYPE_CHARSET); %>
It works fine. Is there any reason for this behaviour.

UnsupportedEncodingException error
Hi to all
Here i made code for converting string to ASCII code but when i press convert button give me UnsupportedEncodingException exception ..
Here is my code:
import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.UnsupportedEncodingException;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.UIManager;
public class ConvertToBinary extends JFrame {
private JPanel mainPanel;
private JLabel label;
private JTextField textField;
private JButton button;
public ConvertToBinary() {
mainPanel = new JPanel(new FlowLayout());
label = new JLabel("Enter your text");
textField = new JTextField(10);
button = new JButton("convert");
mainPanel.add(label);
mainPanel.add(textField);
mainPanel.add(button);
getContentPane().add(mainPanel);
button.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
String string = textField.getText();
StringBuilder result = new StringBuilder();
try {
byte[] b = string.getBytes("USE-ASCII");
for (int i = 0; i < b.length; ++i) {
result.append(b);
JOptionPane.showMessageDialog(null, result.toString());
} catch (UnsupportedEncodingException exp) {
System.out.println("Unsported encoding exception");
public static void main(String[] args) {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (Exception e) {
ConvertToBinary convertToBinary = new ConvertToBinary();
convertToBinary.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
convertToBinary.setSize(new Dimension(600, 300));
convertToBinary.setLocationRelativeTo(null);
convertToBinary.setVisible(true);
convertToBinary.setExtendedState(MAXIMIZED_BOTH);
Thanks in advanceI assume that means that you want to convert the characters of the String to what is called their "ASCII" value in old-fashioned languages which haven't heard of Unicode yet. For example the letter "A" should be converted to the number 65.
You do that by simply casting each character in the String to an int variable. No encodings needed. -
POI UnsupportedEncodingException
Hello all
I'm trying to write my own properties to word document (to store chcecksum). I've compiled poi (all new versions from cvs) to have
mutableclasses. When i run my program i have error UnsupportedEncodingException in line with PropertySetFactory.create(event.getStream()) (when opening polish document coding 1250). Can anyone tell me what is wrong?
I'm not sure that my poi.jar is correct, so can anybody send
me correct compiled jar file (with mutable classes)?
Thx for any help
JarekThere's a US English version of the JRE, and an International Version.
The International version has a lot more Locale specific data/classes and character sets. The US English version used to only support about 7 character sets, the international one has about 144.

Owen
