Using ColdFusion to see Java server values |
||||||||
I've been dabbling in more and more Java recently as an accompaniment to my using ColdFusion development, and I've been finding more and more places where they support each other.
I rolled out a new Application to a live server (this one) and it failed to launch. This was all down to it running an incompatible JVM. So how do you tell what JVM version your server is running? I don't have direct access to this box, so I needed to do it in code.

The Coldfusion Hash() function decoded - kind of |
||||||||
I've always believed that using the hash() function in ColdFusion is a one way process. If I wanted to reverse a string I had to use encode() and decode(). The Adobe documentation states that "It is not possible to convert the hash result back to the source string" - Adobe Docs for Hash().
Strictly speaking this is still true, but some bright spark has decided to host an MD5 string database and provide a lookup service.

Dynamically adding markers to Google maps |
||||||||
Following on from a previous article I wrote about (Google maps panning the next step in my Google mapping project is to be able to add markers to a Google map dynamically.
This article deals with how to translate a location into a latitude and longitude using Google, and how to send and add markers from a database into a Google maps via a remote service, using AJAX and JSON.
There is a full example of the finished application here: Demo of dynamically adding markers to Google maps
