Why don't you let Spring know you want the DataSource bean (defined in
global.xml) injected into your JdbcTemplate?

Then just have your code declare that it needs a
ResetPasswordCounterJDBCTemplate instance and let Spring inject it.
Calling context.getBean() is the wrong way to use the Spring Framework.
Your constructor then becomes:

    public ResetPasswordCounter(ResetPasswordCounterJDBCTemplate
jdbcTemplate) {
      super();
      this.ResetPasswordCounterModel = jdbcTemplate;
    }

You'll also have to make sure Spring loads beans from your
db-connection.xml (import from global.xml, for example), or just define
them in global.xml (that's easier to start with). I'm not sure which of
Spring package/annotation scanning is disabled in the IdP, but this is a
bit more involved here than with Spring's full automation...
