Get value from SQL into an Ant property

Recently I had to adjust some of our JMS configuration and needed make sure we set the ServerPeerID configuration value to a unique value among our servers. We have a unique server number in our database so I figured that I would just use that value. In order to do this, I needed to get the database value into an Ant property, which is then used to generate the configuration file, which includes the ServerPeerID. Below is the Ant task and steps I used to do this.

Steps:

1. Define where the SQL results will be written
2. Make sure the file does not already exist
3. SQL task to get the result
4. Load the file back into a property
   
Use the propertyregex task to strip out just the unique number
