Error 500 outputstream already obtained

Whenever we open an HTML report from a JSP we get the error
"Error 500 outputstream already obtained"

Initially we thought the problem was with the output buffer but it was not. Then we tried by removing the out.println statements in JSP code and replace them with simple HTML text outside the JSP tag.

Below is the code where we think the problem might be.
Also whenever the report is displayed the content is shown and the error is shown at the end of the HTML report.

/***************************** My Reports Starts Here ************************/

if ( reportParameters==null || reportParameters.equals("null") ) {

<%
} else {
StringTokenizer st = new StringTokenizer(reportParameters,":=");
//out.println("<br> <b> Please wait while signing on to WebI.</b>");
while ( (st.countTokens() > 1) && (st.hasMoreTokens()) && ( (!WebIFlag) || (!UNEPFlag)) ) {
String key = st.nextToken();
String val = st.nextToken();

if ( (key.equalsIgnoreCase("WebIFlag")) && (val.equalsIgnoreCase("true")) ) {
WebIFlag = true;
} else WebIFlag = false;

if (val.equalsIgnoreCase("UNEPFlag")) {
UNEPFlag = true;
} else UNEPFlag = false;
} // end while


if (UNEPFlag) {
int index = reportParameters.lastIndexOf(':');
reportParameters = reportParameters.substring(0,index);
// System.out.println("Content Retriever");
pageContext.forward("/ContentRetriever?reportName="+reportName+"&reportDate="+reportDate+"&reportLocation=" + reportLocation + reportParameters);
