Creating JCo destinations

JCo or Java connectors connect SAP EP to the backend systems from which SAP EP takes data to be displayed to the user. Unless you have JCos in place, you wont be able to connect to the backend systems. To create JCos, SSO configuration is a prerequisite.

There are two methods to create JCo destinations.

1. Using the SLD web UI and
2. Using web dynpro content admin tool.

Please post comments on the steps of creation of JCos using the above two methods.
Which method is more suitable and why ?
