In my servlet
an exeception thrown as
org.apache.jasper.JasperException: java.lang.IllegalStateException: getOutputStream() has already been called for this response
help me to solve this problem
thanks in advance
This will happen if a call is made to
ServletResponse.getWriter()when anOutputStreamhas already been created for the response. Only one ofgetWriter()orgetOutputStream()can be used to write a response body, not both.Take a look at the stack trace associated with the exception to see if this is the case. Then, if you are trying to write character data use (only)
getWriter()or for a binary response usegetOutputStream().
