I am using Jetty version 9.3.5 to create ProxyServlet.
To do so, I am extending my class from
org.eclipse.jetty.proxy.ProxyServlet;
Unlike previous version, I do not get the method protected URI rewriteURI(HttpServletRequest request) to override. After reading through grepcode I am seeing something like the followings and used it:
@Override
protected String rewriteTarget(HttpServletRequest request) {
if (!validateDestination(request.getServerName(), request.getServerPort()))
return null;
String roleAlias = (String)request.getSession().getAttribute(ATTR_PROXY_ROLE_ALIAS);
String uri =request.getRequestURI();
String aliasedURI = getAliasedURI(request.getMethod(), uri, roleAlias);
return aliasedURI ;
}
I do not know if this is the correct method to override.
In web.xml I have few filters and this servlet defined. For Servlet I have defined like this:
<servlet>
<servlet-name>Proxy</servlet-name>
<servlet-class>com.company.MyProxyServlet</servlet-class>
<async-supported>true</async-supported>
</servlet>
<servlet-mapping>
<servlet-name>Proxy</servlet-name>
<url-pattern>/proxy/*</url-pattern>
</servlet-mapping>
But I get the following exception? Any idea? Do I need to do same thing for the filters? then how? or what else missing?

Any Help?
Note:- I found few other post related to this error but nowhere the rewriteTarget method is used. Everywhere rewriteURI is used and I do not find it with Jetty 9.3.5.
Please Help.
