Overview ======== This is the exact same example as under examples/ejb/basic/helloworld, except that this example is using SSL client auth. So, except for the SSL details, please refer to the readme file under examples/ejb/basic/helloworld for other details. The purpose of the example is to show how to use ssl client side authentication instead of username/password combination. Setup required -------------- You need to open the encrypted wallet(ewallet.der) provided in this directory using the wallet manager tool provided by Oracle, and save it as clear text wallet (cwallet.sso). The password is welcome12. Copy the generated cwallet.sso into TNS_ADMIN directory. The encrypted wallet(ewallet.der) is only valid for Solaris platforms. For other platforms, you should generate the wallet using Oracle's owm tool. This test also requires B64 encoded wallet(cert.txt) which is already present in this directory. You can also generate your own using Oracle's owmgui tool and using export option in the tool. The parameter SSL_CLIENT_AUTHENTICATION in $TNSADMIN/sqlnet.ora should be set to TRUE. Restart the database. The setup also requires creation of a global user, say guest. The script to create global user is in this directory(create.sh). This script prompts for username and password of a privileged user as input to this script.
