Aaron J. Zirbes ajz@umn.edu \ Provides address lookup service and tags so you can easily add address lookups to your web app if you have a ZP4 HTTPSERV service from Semaphore corp running on your network. From their website: http://www.semaphorecorp.com/cgi/zp4.html ZP4 is a DVD-ROM containing United States addresses, ZIP + 4® codes, mail carrier route numbers, and other supplemental postal databases (all maintained by the Postal Service™), plus complete automatic CASS Certified™ address correction software for Windows computers. This plugin assumes you already have a valid ZP4 DVD, and your Grails app abides by the license agreements: Only accessed by your company, only installed on one computer, etc... For details, see: http://www.semaphorecorp.com/cgi/faq.html#21 I, Aaron Zirbes, the author have no affiliation with Semaphore corp, other than that I am a satisfied paying customer. Their DVD is much more affortable than many similar products available on the market. http://grails.org/plugin/address-lookup-zpfour Config UrlMappings com.semaphorecorp.zp4.AddressLookupController com.semaphorecorp.zp4.AddressService com.semaphorecorp.zp4.ZpTagLib
