java - Response been writen twice in custom servlet forwarding -

i need forward servlet been dynamically loaded jar custom class loader main servlet using external configuration file. servlet not mapped in web.xml. have been able load servlet , construct new instance using reflection , casting:

object o = loadedclass.newinstance() ; httpservlet loadedservlet = (httpservlet) o ; 

i have initialized servlet as:

loadedservlet.init(getservletconfig()) ; 

and implemented every do... method in main servlet as:

loadedservlet.service(request, response) ; 

everything works expected exception of response getting output twice:

hello, world!hello, world! 

is not issue of loaded servlet:

protected void doget(httpservletrequest request, httpservletresponse response) throws servletexception, ioexception {     printwriter printwriter = response.getwriter() ;     printwriter.write("hello, world!") ; }  protected void dopost(httpservletrequest request, httpservletresponse response) throws servletexception, ioexception {     doget(request, response) ; } 

sorry if not enough specific. hint should at?

nevermind, found solution myself. call of response.reset() after calling servlet.service() needed.

loadedservlet.service(request, response) ; response.reset() ;
