Hello, I have a Java Set in my session and a variable also in the session. I need to be able to tell if that variable exists in the set.

I have a servlet which does some error checking and if something is wrong I will typically do this: response.sendError(403, "My message") return; I don't want to throw an exception from the servlet - because I would like to conform with HTTP status codes. In the web.xml I have configured the following: <error-page> <er...

All of this works fine when I save the file directly on my hard drive using ImageIO.write(myBufferedImage, "png", new File("C:/testChart.png")); I can al...
I'm writing a JSP that sometimes needs to format a Java Date that comes out of the request.

However, there are times that the request attribute field with the exact same name (attribute.value) is ...
