One of the limitations of using Spring outside of the traditional J2EE container is hard-coding database information inside the Spring configuration file. If you are deploying the application inside the container, you can simply reference the DataSource via JNDI and not have to provide login, password information about the database connection. To work around that issue, Matt has extended Spring implementation of javax.sql.Datasource and added support for hashing/encrypting the database password. Permalink to Matt’s blog is here .
