getOutputStream() has already been called for this response
Hi,
I am getting getOutputStream() has already been called for this response error in jdk1.4.2 environment.
We have upgraded the sun 6.0 to 6.1, jdk1.4.1 to 1.4.2 and jwsdp1.2 to 1.6. This error is not coming in old environment.
From servlet requestdispatcher is called. Servlet has the "ServletOutputStream out = res.getOutputStream();"
P...InfoServlet.java : 366 and before lines ==
ServletOutputStream out = res.getOutputStream(); //at the top of do get
...............................
ServletContext sc;
RequestDispatcher rd;
req.setAttribute("ic", ic);
req.setAttribute("portObj", pobj);
sc = this.getServletContext();
errmsg = URLEncoder.encode(errmsg,"ISO-8859-1");
rd = sc.getRequestDispatcher("/PortInfoPage.jsp?rc="+rc+"&errmsg="+errmsg);
rd.include(req, res);
_PortInfoPage_jsp.java:792 ==
out.write("\n<TR>\n<TD NOWRAP ALIGN=CENTER VALIGN=MIDDLE COLSPAN=2>\n\n<TABLE BORDER=0 FRAME=NO_FRAME RULES=ALL_RULES ALIGN=CENTER WIDTH=\"100%\" NOWRAP>\n<TR>\n<TD NOWRAP ALIGN=RIGHT VALIGN=MIDDLE COLSPAN=3>\nTo get the current parameter values click here:\n</TD>\n<TD NOWRAP ALIGN=LEFT ALIGN=MIDDLE>\n<INPUT TYPE = \"BUTTON\" NAME = \"\" VALUE=\"Refresh\" onClick=\"refresh()\">\n</TD>\n</TR>\n");
