How to set charset for my web application?

ybxiang.china Mar 21, 2013 4:27 AM

Dear guys,

I am migrating my web application from glassfish 3.1 to jboss7. Now I am suffering charset issues.

charset setting in my web application:

(a) bellow meta is added xtml pages (JSF pages)

(b) In web.xml, bellow lines are added:

	<context-param>
	<param-name>PARAMETER_ENCODING</param-name>
	<param-value>UTF-8</param-value>
	</context-param>

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

<!DOCTYPE sun-web-app PUBLIC "-//Sun Microsystems, Inc.//DTD GlassFish Application Server 3.0 Servlet 3.0//EN" "http://www.sun.com/software/appserver/dtds/sun-web-app_3_0-0.dtd">

<sun-web-app error-url="">

...

<parameter-encoding default-charset="UTF-8"/>

</sun-web-app>

This web application works well in glassfish 3.1.

Now, I remove sun-web.xml from this web application and throw this web application into jboss 7( of course, I modified some configuration files, for example persistence.xml).

My form is:

<h:form id="form" >

<h:panelGrid columns="2">

<h:outputLabel value="Title:" for="title" />

<h:inputText id="title" value="#{topicCreatingMBean.title}" />

<h:outputLabel value="Content" for="content" />

<h:inputTextarea value="#{topicCreatingMBean.content}" id="content" />

<h:commandButton id="submitButton" value="New" action="#{topicCreatingMBean.create()}" />

</h:panelGrid>

</h:form>

Now, I can submit some chinese string into DB, but the title and content in DB are unreadable codes!!!

Something Like: ï¼å¦ä½è®¾ç½®èªå·±ç

Do I miss something???

Is there an equivalent charset setting in jboss-web.xml like sun-web.xml does???

Please help me, thank you very much!

The platform independent way to do this is to use ServletRequest.setCharacterEncoding(java.lang.String) before processing the request parameters.

If you're using a framework that interprets the request for you, you can use a servlet filter instead:

{code:java}public class CharacterEncodingFilter implements javax.servlet.Filter {
 
    ...
 
    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain) throws IOException,
                    ServletException {
        request.setCharacterEncoding("UTF-8");
        filterChain.doFilter(request, response);
    }
 
}{code}

Thank you sir, you are right.
I implemented the filter just now, it works well now.

I had thought there is a parameter to configure such things in JSF2 framework.

Hi, Does not work for me, no clue why. Put the filter in, put a breakpoint in it and verified that it got executed, but still got parameters interpereted as if they were ISO 8859-1, running jboss-as-7.1.1.Final on windows. What solved it was adding
-Dorg.apache.catalina.connector.URI_ENCODING=UTF-8 to the java boot. Right or wrong, but it worked.
