This is a simple example to demonstrate the templating power of JSF facelets. If you've used struts tiles before, you'll recognize the simplicity of templating with facelets. I've stripped out everything else except the pages themselves, just to put our focus on facelets. This is a Maven based project, and you need Tomcat (or any servlet container) to run the resulting webapp. To begin with this is the list of files:
./pom.xml ./src/main/webapp/home.xhtml ./src...I left faces-config.xml in there for completeness sake, it may not be needed. The Maven POM ( pom.xml ):

When you create a new key with Java keytool , it wraps the public key in a self signed certificate. You can generate a certificate signing request with the keytool -certreq command. After a certificate authority (CA) signs the certificate request, you can import the certificate received (a .crt file) back into the key store. Instead of using a CA, you can sign the certificate request with another key (with openssl, for example). If the certificate is not signed by a CA, you'll receive an error:
$ keytool -import -alias android-root -file androi...To fix the problem, import the certificate of the signer:
$ keytool -import -trustcacerts -file openssl.crt ...Import the certificate again (alias is the alias of the private key whose certificate was...

Format Name Description PKCS #7 Cryptographic Message Syntax Standard A PKCS #7 file can be used to store certificates, which is a SignedData structure without data (just the certificates). The file name extension is usually .p7b , .p7c PKCS #8 Private-Key Information Syntax Standard. Used to carry private certificate keypairs (encrypted or unencrypted). PKCS #12 Personal Information Exchange Syntax Standard. Defines a file format commonly used to store private keys with accompanying public key certificates, protected with a password-based symmetric key. It is the successor to PFX from Microsoft.
