Updating cache when file is changed.
Hi all,
I am working on a "Resource Manager" module in java. What it does is :
1. Read the configuration file from a location(proerty name/value pair).
2. Loads the file properties in a cache which holds the in a CachedHashMap as Key-Value pair
The same config file which it reads looks like this:
<config>
<client>
<id>1</id>
<application>
<id>213</id>
<name> MyApp </name>
<property>
<name> key1 </name>
<value> value1 </value>
</property>
<property>
<name> key2 </name>
<value> value2 </value>
</property>
</application?
></client>
</config>
This reading from config file and storing in cache I have already implemented ..
But now I have a special requirement.. If after deploying the application, I modify the file then Resource Manager should be smart enuf to detect the change and the reloads the file , cleans the cache and updates the cache..
Can you guys please through an idea on how to achieve the same? It has to be Server Independent... I mean no JMX..
a small small code will b more useful..
Thanks in advance
Pankaj
