In most MVC based framework I see a router object. If I look at it splits up the uri and decides what controller should be used, and which action should be fired.
Even though this makes a lot of sense, I can not give this a place in the MVC patern. Is splitting up the uri not the job of the controller. And then the controller should just decide which class and function to run.
I was trying to execute the below code in my javascript and got some exception

I like the ease of using @Resource annotation to get a DataSource, but as far as I know, it's not possible to use it in a regular JavaBean. Would it be considered a bad practice if I pass the DataSource object from a servlet to a bean along with the other data to avoid having that lookup code in the bean?
I have code that looks like this:
public class Polynomial {
List<Term> term = new LinkedList<Term>();
and it seems that whenever I do something like term.add(anotherTerm), with anotherTerm being... another Term object, it seems anotherTerm is referencing the same thing as what I've just inserted into term so that whenever I try to change anotherTerm, term.get(2) (let's say) get's changed too.
How can I prevent this from happening?
How can I get the session from within a command object?
I have tried:
import org.springframework.security.context.SecurityContextHolder as SCH
class MyCommand {
def session = RCH.currentRequestAttributes().getSession()
}
This throws
java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

Hello,
I have the following:
Class 1 (Text, State, Level)
Class 2 (Text, State, Level, Ident)
Is there a way for me to cast an object of Class 2 into into Class 1, and not having to do the usual cast code (Text = c.Text, State = c.State etc.)? Possibly by identifying the property names of each class and copying the value over?
hey all
i am trying to aggregate form elements into object and then send it via ajax here is the code that i start using but i cant figure out how to do the rest

Doctrine Automatically creates indexes on columns that are used to define object relations,
For example
user: id, name
message: id, sender_id, receiver_id, message
if I define relationship between message and user in a way that message has one Sender and has one Receiver, doctrine will automatically index sender_id and receiver_id fields when I generate sql from model. I would like to disable index on sender, because I manually create index with sender_id and receiver id together. How can I disable auto generated index?
Hi,
I am looking for how to write a method that accepts some value and returns a proxy to that value where the underlying value can be retrieved with an accessor:
def p = toProxy(1)
assert p == 1
assert p * 2 == 2
assert p.underlying == 1
def p2 = toProxy(objWithMethodFoo)
p2.foo()
p2.underlying.foo()
I want to do this per object instance (not for all objects of some class) and without the need to use special 'use' constructs.
I'm trying to convert a dictionery into a json object, so that I can work with it in my front end.
sortFields = <%= SchrodersHtmlHelper.ToJson(ViewData["SortInfo"])%>;
However, I keep on getting "Expected expression" for this all the time and I'm clueless why. Could anyone explain to me what I'm doing wrong?
Edit: The conversion works fine, but I still get this issue in the front end, causing the browser to complain about it.

I am a rank beginner in C#. I am currently using this code:
objGraphics.Clear(SystemColors.Control);
What I want to do is Clear this object to black (or some other RGB color), and I'm stumped as to how to replace the SystemColors.Control with, preferably, an RGB color spec. I'd probably want to clear to black most of the time. Any help will be much appreciated!
string a = "a";
string b = a;
string a = "c"
Why does string b still have the value "a" and not "c"?
As string is an object and not a stack value type, what's with this behaviour?

Hi there, i run a C++ app from objective-c
I can successfully symbolicate my function names using Shark profiler but not with the Object Allocations instrument.à
In the detailed pane, i only see my C++ app name with the hexadecimal value for my C++ functions.

Any clues?

I have an object (Contacts) which has two has_many relationships: Campaign and Company
When I am in the Campaign view, I want to add a Contact.
But without a Company_Id, Controller says cannot find company_id (which needs to be there if I add a Contact through the Company).
What should I do?

I've got a 'MyDataTable' class that inherits from System.Data.DataTable
I've implemented ISerializable in my class and have a 'Public Overrides Sub GetObjectData...'
But when I try to serialize the an object of 'MyDataTable' I get an error saying that 'MyDataTable' is not marked as serializable.
If I used a DataTable instead - my code serializes correctly.
If I add a serializable attribute to the 'MyDataTable' class - it serializes correctly, but I'm told that is unnecessary if I implement ISerializable.
Can someone point me in the right direction?
I am using the DataTables plugin for jQuery and need to get one of the table rows. DataTables has a fnGetNodes function that returns an Array with all of the DOMElements of the table. I would like to use a jQuery selector to find that row (I know the id of the row), but I need to convert the Array to a jQuery Object, is this possible?
