How to enable page encoding on the whole jsp page

I included <%@ page contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> on one jsp page and correctly displayed French characters. But I want to enable page encoding on all jsp pages. In web.xml I have included

 <jsp-config> <jsp-property-group> <url-pattern>*.jsp</url-pattern> <page-encoding>UTF-8</page-encoding> </jsp-property-group> </jsp-config>

but it will work for tomcat7, I am using tomcat6.

Is there any other solution for this?

You can use the meta tag instead of adding the page encoding to the whole jsp file or to web.xml. If you have a shared .jsp file, include

You can define a new filter in your web.xml and change your answers there.

For example, you can put this in your web.xml:

 <filter> <filter-name>encoding</filter-name> <filter-class>com.example.EncodingFilter</filter-class> </filter> <filter-mapping> <filter-name>encoding</filter-name> <url-pattern>/*.jsp</url-pattern> <!-- or any pattern you like to excluse non-jsp resources --> </filter-mapping>

And create the class com.example.EncodingFilter as follows:

 public class EncodingFilter implements javax.servlet.Filter { // init, destroy, etc. implementation public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { response.setCharacterEncoding("utf-8"); chain.doFilter(request, response); // pass request to next filter } }

Alternatively, you could add tests around your setCharacterEncoding() call to filter only a specific URI or exception, such as non-HTML jsp or a specific parameter, such as PDF JSP output if the URL format=PDF parameter is specified:

 if (!request.getQueryString().contains("format=PDF") { response.setCharacterEncoding("utf-8"); } chain.doFilter(request, response); // pass request to next filter

If your settings are not UTF-8 encoded when using Tomcat, try configuring the connector in Tomcat server.xml as follows:
<Connector port="8080" maxHttpHeaderSize="8192" maxThreads="150" minSpareThreads="25" maxSpareThreads="75" enableLookups="false" redirectPort="8443" acceptCount="100" connectionTimeout="20000" disableUploadTimeout="true" URIEncoding="UTF-8" />

Another way to apply encoding to all pages is to use a filter.

 public void doFilter(ServletRequest request,ServletResponse response, FilterChain filterChain) throws IOException, ServletException { request.setCharacterEncoding(encoding); // response.setContentType("text/html;charset=UTF-8"); response.setCharacterEncoding(encoding); filterChain.doFilter(request, response); } public void init(FilterConfig filterConfig) throws ServletException { String encodingParam = filterConfig.getInitParameter("encoding"); if (encodingParam != null) { encoding = encodingParam; } }

Register this filter in web.xml
