Database Connection Pooling
Database connection pooling enhances the performance of servlet or JSP database
interactions. There are several JDBC 2.0 compatible drivers that support connection
pooling, for example Oracle8i™ update and CloudScape™ 3.0.
Fetching the Client Certificate
When you enable SSL and require client certificate authorization, your servlets
have access to the client certificate as shown in the following example:
if (request.isSecure()) {
java.security.cert.X509Certificate[] certs;
certs =
request.getAttribute("javax.servlet.request.X509Certificate");
if (certs != null) {
clientCert.getSubjectDN();
}
}
The
userDn
clientCert = certs[0];
if (clientCert != null) {
// Get the Distinguised Name for the user.
java.security.Principal userDN =
...
}
is the fully qualified Distinguished Name for the user.
