Automated deployment using Ant tool

Hi, I'm looking for a an ant script. The script must be able to checkout from svn using tags, separate static and dynamic content and deploy static content on the web server docroot and dynamic content on weblogic side. It must create a war file with classes along with jsp's and then deploy onto weblogic. If there is an update to single jsp file in the future,then it must be able to redo the war file and then deploy onto weblogic. Uploaded file is the sub version taxonomy. There are multiple domains in our weblogic server and we deploy war files onto managed server. Thanks
