1) need set data content type utf-8 before submitting data. because receiver(in case, servlet) needs know encoding set(in jsp) data before servlet decodes bytes.
ie: request.setcharacterencoding("utf-8");
2) <%@page pageencoding="utf-8"%> not used java data. line used tell language jsp file written in. ie: english, chinese. think totally misunderstood line.
answer updated:
3) remove line >> string(request.getparameter("brokerstext").getbytes("iso-8859-1")), "utf-8"); don't need convert received utf-8 bytes iso.
note: please post jsp code
