#### To configure Application Server facilities for use by message security providers

1. If using a version of Java SDK prior to version 1.5.0 (J2SE 5), and using encryption technology, configure a JCE provider.

   Configuring a JCE provider is discussed in To configure a JCE Provider for J2SE 1.4.

2. If using a username token, configure a user database, if necessary.

   When using a username/password token, first configure an appropriate realm and an appropriate user database for the realm.

   Configuring a user database is discussed in To edit a realm.

3. Manage certificates and private keys, if necessary.

   For information on managing certificates and private keys, see "Working with Certificates and SSL" in Sun Java System Application Server Platform Edition 9 Administration Guide.

##### Next Steps

Once the facilities of the Application Server are configured for use by message security providers, then the providers installed with the Application Server may be enabled as described in To enable providers for message security.
