Mojarra 2.2.3 encoding request parameters

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:
