[jbossws-users] Where to put initialization code of a Web Service?

Hi, After exhaustively searching JBossWS documentation I could not find the answer to this simple question: I'm developing a Web Service in JBoss AS 7 that needs to establish a connection to a local database before it can serve client requests. I thought about putting the initialization code in the constructor method of the class that implements the Web Service, but I could never find any documentation that suggested that. What is the best place to put this initialization code? Thanks in advance. Joao
