問題
Caused by: java.util.zip.DataFormatException: incorrect data check
原因
火狐瀏覽器與richfaces控件不兼容
解決
（1）創建工具類
package com.truesafer.common;
import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.net.URLDecoder;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletRequestWrapper;
public class RichFacesFirefox11Filter implements Filter {
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
chain.doFilter(new HttpServletRequestWrapper((HttpServletRequest) request) {
@Override
public String getRequestURI() {
try {
return URLDecoder.decode(super.getRequestURI(), "UTF-8");
} catch (UnsupportedEncodingException e) {
throw new IllegalStateException("Cannot decode request URI.", e);
}
}
}, response);
}
public void init(FilterConfig filterConfig) throws ServletException {
// do nothing
}
public void destroy() {
// do nothing
}
}
（2）在web.xml加入下面代碼
<filter>
<filter-name>RichFacesFirefox11Filter</filter-name>
<filter-class>com.truesafer.common.RichFacesFirefox11Filter</filter-class>
</filter>
<filter-mapping>
<filter-name>RichFacesFirefox11Filter</filter-name>
<url-pattern>/a4j/*</url-pattern>
</filter-mapping>
