Here's another suggestion. If your app requires a lot of calls to Salesforce because there are many objects objects being used, performance can be a limiting factor. Typical response per API call is about half a second. Do the math (multiply the number of objects accessed times half a second), and you may find you're better off with a local replicated database. Relational Junction offers bi-directional real-time replication between Salesforce and a local dataabase, making it a great platform for custom web applications. Using JDBC or Hibernate to access the database is a lot quicker to develop, as well, and you probably already know how to do that.

http://wiki.developerforce.com/index.php/Integration see the web services api guide, and the java samples.
I use http://code.google.com/p/sqlforce/wiki/JavaForce and talk via Java. We use the library in standalone java apps, tomcat/servlets, and in axis2 web services.
Talking from SFDC to a web service is fairly simple:
1. Configure the IP to your web service provider as open in SFDC.
2. Save a wdsl for your web service to a file.
3. Use Create a Class from a WSDL on the SFDC Create/Class page.
