[jboss-as7-dev] Domain Management - Add support for database authentication. Need advice

Hi everybody I'm currently working on "Domain Management - Add support for database authentication" https://issues.jboss.org/browse/AS7-1370 and https://issues.jboss.org/browse/AS7-1371 and struggling with a design issue. What I need to solve is that you are able to setup a connection pool for database authentication, and I was told that I could not depend on the JBOSS subsystem when running in domain mode. So I basic need some functionality to handle a database connection pool, I can see 3 options but I don't know what is the best approach and what the guidelines are 1. Reuse some existing code in the project, I don't if it possible to take advantage of existing code for maintaining a database connection pool? 2. Use an existing 3 party lib, that will provide this functionality. I don't what are the common guidelines for adding new 3 party libs to the project?. 3. Write my own simple connection pool manager. I was started on no. 3 and don't think it will be a huge task. What do you think, does it make sense? br Flemming
