Hi! I have a task, to read XML file from FTP server (data output in the table). My implementation is not the best: file is downloaded to hard drive and then it is read from given path, for example 'C:/something.xml'. Personally I don't like it, but I couldn't find better solution. I guess there should be options to save file to RAM and and then to read it from RAM, or may be directly from FTP. I will appreciate your opinion and advice.

While programming in Java in my latest version of netbeans, whenever I try to execute my program it shows null pointer exception though I have declared and initialized the variables. Can it be due to some other reasons also? If yes, what are they? Or can it be due to improper or incomplete installation of Netbeans?

I have JDK 6 installed in my computer. Applications in command prompt or Swing based applications work completely fine. Problem is with applets. When I tried to run my applet in Google Chrome, it shows a blank area and the error shown is,"Java(TM) is required to display some elements on this page". In front of that, a "Install plug in" option is there. I clicked it and it shows download java. It is not the plug in, it's again the whole JDK. I have JDK already installed, why should I again download it? Please tell some alternatives.
