| | Push the list into the session and access it in your JSP using [URL="http://www.ibm.com/developerworks/java/library/j-jstl0211.html"]JSTL[/URL]. Look into the c:forEach tag of JSTL. |
| | Use JSP's only for presenting data / view purposes only; use servlets for processing. Submit the above form to a servlet which would grab the mail related details, create a SMTPSender instance with the values obtained and do the required task. |
| | A lot of complicated terminology being thrown around here but a few points: > A static member of a class is a shared location in memory between objects of that class.

| | You need to provide a default constructor for the `Circle' class. Also, since `main' method is `static', you can't access instance variables inside it. It wouldn't make sense to access something which pertains to the state of a `Circle' inside a method which can be invoked without a `Circle' instance. …  |

| | AFAIK, the implementation of [ICODE]hashCode()[/ICODE] and [ICODE]equals [/ICODE]method of [ICODE]File [/ICODE]class depends on the underlying file system. On Windows files systems, the [ICODE]hashCode()[/ICODE] method of the [ICODE]File [/ICODE]class is actually the hash code of the result of [ICODE]getPath()[/ICODE] after converting it to lowercase. The [ICODE]equals()[/ICODE] method compares the result of … |

| | Make sure your SELECT elements have a name attribute which can be then used to retrieve the selected value using [ICODE]ServletRequest.getParameter[/ICODE] in case only single selection is allowed or [ICODE]ServletRequest.getParameterValues[/ICODE] in case multiple selections are allowed. Don't use JSP's for anything other than presenting the data; use servlets for handling … |

Just create an interface [ICODE]Collidable [/ICODE]which exposes a contract of the form [icode]Outcome collide(Collidable c)[/icode]. Make classes implement this interface and implement the … |
| | > Can it be something to do with the @ sign? Yes. Make sure you *always* encode user entered data; at least when making asynchronous calls using Ajax. Normal submits automatically encode the form data for you. Use [URL="http://developer.mozilla.org/en/Core_JavaScript_1.5_Reference/Global_Functions/encodeURIComponent"]encodeURIComponent[/URL]. |

| | It's not pretty clear what you mean by the `First Node' since there is nothing of that sort in your program. What are the specifications of the LinkedList you are trying to create here? Without having an inking of how things ought to be, helping you out would be difficult. … |

| | Re: Autocompleter Your solution can be roughly broken into the following tasks: - Design a web page as per your requirement - Attach a listener to the key handler which monitors keystrokes pressed inside the search text box. - In that listener, create a XHR (XMLHttpRequest) object which asynchronously polls the server … |

| | The term 'best' would be relative in the context you mention. There is no single 'do-it-all' library out there. For e.g. Ogre is a pretty good game engine but the most complicated all of them out there. Irrlicht is pretty much easier to pick up but doesn't provide the fine … |

| | This sure is a weird problem; without looking at the code, it would be kind of difficult to arrive at a solution. BTW, how are you attaching event listeners to your components? Are you using [ICODE]attachEvent [/ICODE]/ [ICODE]addEventListener [/ICODE]or the plain old way of attaching events? |
