How to determine inbound headers, url, cookies and other http request parts in a jrxml report

Issue Description

In certain cases you want your report to behave conditionally based on the HTTP Request for the report.

Resolution

You can access the application server's java.servlet.http.HttpServletRequest object to lookup information from the request via an expression like this one which calls the getHeader() method on the HttpServletRequest object:

<textFieldExpression><![CDATA[((javax.servlet.http.HttpServletRequest)$P{REPORT_PARAMETERS_MAP}.get("HTTP_SERVLET_REQUEST")).getHeader("Host")]]></textFieldExpression>

Review the java Servlet api objects linked below to see syntax for getting Cookies, parts of the url, etc.
