unicode escaping problem

[zealot]

Hi all.
May be this question is JSF specific but I can't find solution for a five days.
I'm using SEAM + Facelets + EJB3.
When I post some data in Russian on <h:inputText>, I see codes of those charactrers when form redisplays instead of characters. On sun's forums I found that characters that are "dangerous" in HTML are escaped. But how can I get real characters from form.

my code
<h:inputText id="searchString" value="#{productOrdering.searchString}"/>

Please help me, this is very important for me.

Thanks
--Andrew

Hadn't anyone had such a problem? Are here any people not from english-speaking country?

See if you can ask the guy who puts up this website:

We have 11 to support. Painful ;-)

I have conducted a few experiments to try and solve it. I have seen that using Linux based browsers with Unicode (Mozilla, Firefox) seems to work OK. Using IE on Windows I am able to enter the Unicode, but the re-display in the inputtext shows the hex values.

Did you try your application through different browsers? Would be interesting to know if you have the same behavior.

Is your persistence store configured to save Unicode ? (I created my postgresql instance with "createdb -E UNICODE instancename")

Thanks for your reply Louis.
I tested on FreeBSD and on Windows
on FreeBSD:Firefox I get hex values
on FreeBSD:Opera I get hex values
but on FreeBSD we have russian encoding KOI8-R
on Win:Firefox I get hex values
on Win:Opera I get hex values
and
on Win:IE I get charecters on "some" encoding, not UTF-8, not cp1251 and not ISO8859-1
:-(
Yes my databese created with UTF-8 :-(

So how can we solve this problem?

again thanks for your reply

Page rendered with encoding ISO8859-1 on Firefox
and with encoding UTF-8 on IE

On facelets issue trucking system I found that page must be encoded with UTF-8 by default.

So IE show page in correct encoding, and firefox - not

[zealot]

But problem is still there:

if page rendered in UTF-8 I get charecters on "some" encoding, not UTF-8, not cp1251 and not ISO8859-1

if page rendered in ISO8859-1 I get hex values of input characters

try to register this filter,

but it? a hack for Oracle ADF, because some time Oracle ADF components reset utf encoding to ISO

public class UTF8Filter implements Filter {

 public UTF8Filter() {
 super();
 }

 public void init(FilterConfig arg0) throws ServletException {
 // TODO Auto-generated method stub

 }

 public void doFilter(ServletRequest request, ServletResponse response,
 FilterChain chain) throws IOException, ServletException {
 HttpServletResponse r2 = (HttpServletResponse) response;
 r2.setContentType("text/html; charset=utf-8");
 response.setCharacterEncoding("utf-8");

 chain.doFilter(new ServletRequestUTF8((HttpServletRequest) request),
 new MyResponseWrapper((HttpServletResponse) response));

 }

 public void destroy() {
 // TODO Auto-generated method stub

 }

}

class MyResponseWrapper extends HttpServletResponseWrapper{

 @Override
 public void setHeader(String arg0, String arg1) {
 // TODO Auto-generated method stub
 super.setHeader(arg0, arg1);
 }

 @Override
 public void setContentType(String arg0) {
 // TODO Auto-generated method stub
 super.setContentType("text/html; charset=utf-8");
 }

 @Override
 public void setResponse(ServletResponse arg0) {
 // TODO Auto-generated method stub
 super.setResponse(arg0);
 }

 @Override
 public String getCharacterEncoding() {
 // TODO Auto-generated method stub
 return "utf-8";
 }

 @Override
 public void setCharacterEncoding(String arg0) {
 // TODO Auto-generated method stub
 //super.setCharacterEncoding(arg0);
 }

 public MyResponseWrapper(HttpServletResponse arg0) {
 super(arg0);
 // TODO Auto-generated constructor stub
 }


}

class ServletRequestUTF8 extends HttpServletRequestWrapper {

 /**
 * @param arg0
 */
 public ServletRequestUTF8(HttpServletRequest arg0) {
 super(arg0);
 // TODO Auto-generated constructor stub
 }

 public String getParameter(String arg0) {
 return convertUTF8(super.getParameter(arg0));
 }

 /**
 * @param parameter
 * @return
 */
 private String convertUTF8(String value) {
 if (value == null) {
 return value;
 }
 try {
 return new String(value.getBytes("ISO-8859-1"), "UTF-8");
 } catch (Throwable e) {
 e.printStackTrace();
 return value;
 }
 }

 public String[] getParameterValues(String arg0) {
 String[] values = super.getParameterValues(arg0);
 if (values == null){
 return null;
 }
 for (int i = 0; i < values.length; i++) {
 values = convertUTF8(values);

 }
 return values;
 }
}

Wow It's finaly working now!!!!!!!

Thanks everyone

Hi

I havent tried the filter solution above. The following
https://facelets.dev.java.net/servlets/ReadMsg?list=users&msgNo=1403
has helped me! In short it uses a JSF Phase listerner.

nice eclipse resource bundle editor makes your happiness complete

Without the JSF Phase listeners, I can input and show japanese characters correctly on utf-8 pages after installing facelets-1.1.11 for the seam package.
I recomend the newer versions of facelets.
