RE: Encoding issues

[Altankov Peter]

I used to have similar problems with windows-1251 cyrylic codeapge and I solved it by 
creating a siple filter, mapped to all request that explicitly sets the encoding of 
the request before any1 else gets the request:

        request.setCharacterEncoding("windows-1251");

I think this happens because Internet Explorer does not set the appropriate encoding 
headers on HTTP level of the protocol and tomcat just assumes it is ISO8859-1 (leading 
to garbage ofcourse)


Here is the full source of the filter:
package bg.cbm.servlet.filter;

import javax.servlet.*;
import java.io.IOException;

/**
 * Creator: paltankov
 * Date: 2003-10-30
 * Time: 10:03:49
 */
public class LocaleHelperFilter implements Filter
{
        private String defaultRequestEncoding = null;

        public void init (FilterConfig filterConfig) {
        defaultRequestEncoding = 
filterConfig.getInitParameter("defaultRequestEncoding");
        }

        public void doFilter(ServletRequest request, ServletResponse response, 
FilterChain chain)
                                          throws IOException, ServletException {

                if (null == request.getCharacterEncoding())
                        request.setCharacterEncoding(defaultRequestEncoding);

                chain.doFilter(request, response);
        }

        public void destroy() {}

}


Here is the mapping entry for web.xml of the application that uses it:

        <filter>
                <filter-name>localeHelper</filter-name>
                <filter-class>bg.cbm.servlet.filter.LocaleHelperFilter</filter-class>
                <init-param>
                        <param-name>defaultRequestEncoding</param-name>
                        <param-value>windows-1251</param-value>
                </init-param>
        </filter>

        <filter-mapping>
                <filter-name>localeHelper</filter-name>
                <url-pattern>*.jsp</url-pattern>
        </filter-mapping>

I hope this helps (making my sleepless nights worth :)))
cheers
