Hi All
I have not done java web programming for 1 year, actually still very junior at it.
Trying to remember how to program jsp's again.
I have a simple jsp to write, that takes simple user text input and then want the jsp to return xml back to browser.
I have a method I would like to use called setContentType but have not been able to use it in the jsp.
I have listed the code below, when I run the jsp from tomcat servlet container, it throws up an error
"The method setContextType(String) is undefined for the type HttpServletResponse"
Not sure why it should throw up the error as setContextType method is from the ServletResponse that is a
super class of HttpServletResponse.
Please help as not sure what the issue is!

out.println("</FORM>");
} else {
response.setContextType("text/xml");
response.setHeader("Cache-Control","no-cache");
out.println("The result is 9003888");
