I would like to print the cause of the HTTP Error 500 on my Velocity template but am having difficulty figuring out how this can be done. My web.xml is configured with: <error-page> <error-code>500</error-code> <location>/error/500</location> </error-page> The location is backed by a Spring controller. The 500.vm page is resol...
Using spring MVC, how would I create a form that doesn't map to a entity (i.e. it has properties from multiple entities). I want to also validate and use their 'results' object that has the errors collection etc. Any online examples of this? I need to see it to understand it (newbie) ...
Hello, I want to move something a set distance. However in my system there is inertia/drag/negative accelaration. I'm using a simple calculation like this for it: v = oldV + ((targetV - oldV) * inertia) Applying that over a number of frames makes the movement 'ramp up' or decay, eg: v = 10 + ((0 - 10) * 0.25) = 7.5 // velocity chang...

Hello, I have an array set inside a velocity template that contains some paths. The idea is to put a few "default" .js/.css files that 90% of the pages will use in this array. However, the other pages will still have to be able to add/delete values from this array, in case there are no linked files at all, or I need to add some. Given ...

I'm trying to get Velocity to output the following Javascript code: if ((whichOne+1) <= numCallouts ) { whichOne = whichOne + 1; } else { whichOne = 1; } Whenever I try to get Velocity to print a > or a <, it represents it as a & gt; or & lt;, which doesn't help me since I'm trying to get it to produce Javascript. I've tried: #s...
Hello, I have a fairly simple question about these 2 templating engines. I'm trying to make a future/paste date, a fixed time from now, e.g. 18 months ago, or tomorrow. I know that it is possible to do this with a java date object inside a velocity/freemarker template (something like $date.add(2,-18)), but I would like to do this with D...

But when I do : #foreach (${validType} in ${validTypes}) ${validType} #end it works fine. Do I need to use velocity tools for this? How do I use it in an eclipse plugin? Are there any work ar...
I am using NVelocity to process various PowerShell scripts before they are executed against a server. My question is how to escape a backslash trailing a variable: e.g. ls \\$computername\c$ $computername should be replaced with a valid computer name at runtime, but the trailing backslash (\c$) means that it does not. Thanks Ben ...
Does anyone know if Core Location in the iPhone OS uses anything but simple vector math to calculate speed? I've read that the GPS system can provide speed measurements that can be accurate when position is not (I believe using the Doppler shifts of the signals). I've tried and failed to see if the iPhone does this. The question is basi...
