ADF/WebCenter :Bypass the IE Compatibility Mode in IE8/9

Step 1 :Create a filter MyServletFilter.java

 

public class MyServletFilter implements Filter{

public MyServletFilter() {

super();

}

public void init(FilterConfig filterConfig) {

}

public void doFilter(ServletRequest servletRequest,

ServletResponse servletResponse,

FilterChain filterChain) throws IOException,

ServletException {

if (servletRequest instanceof HttpServletRequest){

HttpServletRequest req = (HttpServletRequest)servletRequest;

MyServletRequestWrapper wrapper = new MyServletRequestWrapper(req);

filterChain.doFilter(wrapper, servletResponse);

} else {

filterChain.doFilter(servletRequest, servletResponse);

}

return;

}

public void destroy() {

}

}

Step 2 : Create MyServletRequestWrapper.java class

 

public class MyServletRequestWrapper extends HttpServletRequestWrapper {

public MyServletRequestWrapper(HttpServletRequest httpServletRequest) {

super(httpServletRequest);

}

@Override

public String getHeader(String header_key) {

String header_val = super.getHeader(header_key);

if (header_key.equalsIgnoreCase("user-agent")) {

int index = header_val.indexOf("IE 7.0");

if (index != -1) {

StringBuffer temp_val = new StringBuffer(header_val);

temp_val = temp_val.replace(index, index + 6, "IE 8.0");

header_val = temp_val.toString();

}

}

return header_val;

}

@Override

public Enumeration getHeaders(String header_key) {

if (!header_key.equalsIgnoreCase("user-agent")) {

return super.getHeaders(header_key);

}

Vector<String> list = new Vector<String>(1);

String temp = this.getHeader(header_key);

list.add(temp);

return list.elements();

}

}

Step 3 :Register MyServletFilter in web.xml

<filter>

<filter-name>myServletFilter</filter-name>

<filter-class>com.servlet.filter.MyServletFilter</filter-class>

</filter>

 

Step 4: Add filter mapping in web.xml

<filter-mapping>
<filter-name>myServletFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
