Mojarra 2.2.3编码请求参数

Question

Problems started when I upgraded Mojarra from 2.2.1 to 2.2.3 (JBoss Wildfly Alpha to Beta).

When I try to submit a form (POST) with special characters (polish letters) they aren't properly UTF-8 encoded.

What I have done?

• Wrote a filter

   @WebFilter(urlPatterns = "/*", initParams = { @WebInitParam(name = "ignore", value = "true" ), @WebInitParam(name = "encoding", value = "UTF-8") }) public class CharacterEncodingFilter implements Filter { private String encoding = null; private FilterConfig filterConfig; // Should a character encoding specified by client be ignored private boolean ignore = true; @Override public void init(FilterConfig filterConfig) throws ServletException { this.filterConfig = filterConfig; this.encoding = filterConfig.getInitParameter("encoding"); String value = filterConfig.getInitParameter("ignore"); this.ignore = ((value == null) || value.equalsIgnoreCase("true") || value.equalsIgnoreCase("yes")); } @Override public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { if ((ignore || (request.getCharacterEncoding() == null)) && (encoding != null)) { request.setCharacterEncoding(encoding); response.setCharacterEncoding(encoding); } chain.doFilter(request, response); } @Override public void destroy() { this.encoding = null; this.filterConfig = null; } } 

• Every XHTML contains a line

  <?xml version="1.0" encoding="UTF-8"?>

• Layout also contains information about encoding

  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

• Added properties to standalone.xml

   <property name="org.apache.catalina.connector.URI_ENCODING" value="UTF-8"/> <property name="org.apache.catalina.connector.USE_BODY_ENCODING_FOR_QUERY_STRING" value="true"/> <property name="file.encoding" value="UTF-8"/> 

• Logs in console when debugging request parameters from filter

  index_form:people: Tischner PrzemysÅaw

  index_form:j_idt66: index_form:j_idt66

  index_form: index_form

  index_form:dbId: 2881850

  javax.faces.ViewState: 2748560203387116963:2575775533048879716

• Request preview in browser

• How I initialize JSF page

   <f:metadata> <f:viewParam name="name" value="#{followNewView.name}" /> <f:viewParam name="company" value="#{followNewView.company}" /> <f:viewParam name="companyURL" value="#{followNewView.companyURL}" /> <f:viewAction action="#{followNewView.init}" /> </f:metadata> 

Finally I'm still ending with improper encoding:

Answer 1

The problem was in Undertow encoding.

Solution here: https://issues.jboss.org/browse/WFLY-2533

Answer 2

here is a Bug about this:

https://issues.jboss.org/browse/WFLY-2550

and here is one possible solution:

add this after your filter in web.xml:

<filter-mapping>
    <filter-name>CDI Conversation Filter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

as described here:
