Tweak Character Encoding to UTF-8 only for one request

[Deeps Mistry]

Hi,

I have an application with Web Work + Spring + Hibernate.

I have defined webwork.i18n.encoding=ISO8859-1 in webwork.properties file.

I chose 'ISO-8859-1' encoding because i wanted to save special characters in my database.

In one particular case, i send my request(form with hidden variables ) to a third party drafter..which has character encoding set to "UTF-8".

Now whenever i pass the request (which contains special characters) from my application to the third party, first time it shows the correct special character, but on subsequent request, it gives me a '?' or a rectangular box.

If we start a new browser instance everytime then it shows up properly.

I tried the following -
I tried to do in my filter

request.setCharacterEncoding("UTF-8");

It does change the request encoding, till the time it calls FilterDispatcher.java where in it reads from webwork.properties and changes the character encoding back to "ISO-8895-1".

What should i do now?

Is there any way to tweak FilterDispatcher for one particular request?



Thanks.

Imagining you were working with struts2. You can set this in struts.properties file.

### This can be used to set your default locale and encoding scheme
# struts.locale=en_US
struts.i18n.encoding=UTF-8

if you want to override it to a particular request then you have to override FilterDispatcher(Use StrutsPrepareAndExecuteFilter).

We are using WebWorks.

I tried overriding FilterDispatcher with TestFilter.java.
In my web.xml I configured this filter for a particular request.
On request, doFilter() method of TestFilter does get called, but at the end , doFilter() method of FilterDispatcher gets called. So i end up without my encoding being changed.

Is this the right way to do it? I think I am doing something wrong.

Here is my code -

public class TestFilter extends FilterDispatcher implements Filter{
      private String encoding;
    public void init(FilterConfig filterConfig) throws ServletException {

        this.encoding = filterConfig.getInitParameter("encoding");
    }
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
        servletRequest.setCharacterEncoding(this.encoding);
        HttpServletRequest req = (HttpServletRequest) servletRequest;
        String requestURI = req.getRequestURI();
        HttpServletResponse response = (HttpServletResponse) servletResponse;
		req.setCharacterEncoding(encoding);
        response.setCharacterEncoding(encoding);
        filterChain.doFilter(servletRequest, servletResponse);
    }
    public void destroy() {
    }

}

<filter>
        <filter-name>test</filter-name>
        <filter-class>com.kernel.security.TestFilter</filter-class>
        <init-param>
         <param-name>encoding</param-name>
         <param-value>UTF-8</param-value>
         </init-param>
    </filter>

 <filter-mapping>
        <filter-name>test</filter-name>
        <url-pattern>/secure/InvokeAssembler.action</url-pattern>
    </filter-mapping>

Hi Deeps,
Never worked on WebWorks. Have you seen this thread

Thanks for your quick reply.

In my case , it is reading webwork.i18n.encoding=ISO8859-1 in the FilterDispatcher.java.

I want it to bypass it for one particular request.


Thanks.
