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 GUI screen sidebar - servlet is called and from servlet jsp is
included using the requestDispatcher.

"ServletOutputStream out = res.getOutputStream();"

Is there other way to include the jsp??

servlet code :
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 ");

Here is the stack
