This document contains all the use cases related to the Petals-BC-SOAP component.
Use cases are ordered by their complexity, from the most simple to the most complex ones.

h1. Simple Use Cases

This sample using SSL requires the following key stores:
* a key store 'external': keystore-external.jks (password: keystoreextpwd), containing the private and public key of the external service provider. The private key is protected by the password `keyextpwd`,
* a key store 'petals': keystore-petals.jks (password: keystorepetals), containing the private and public key of Petals service consumer re-exposing the external service provider to outside.

h3. About the service provider

A service provider 'ArticleServiceContinuation' is available as a SoapUI mock secured by SSL and WSS at [http://localhost:8088/mockArticleServiceContinuationSoap11Binding-SSL-WSS?wsdl]. Just import the [SoapUI project|https://svn.petalslink.org/svnroot/trunk/product/dev/prod/petals/petals-samples/petals-samples-soap/sa-SOAP-samples-Proxy-SSL-WSS/src/soapui/Petals-Samples---BC-SOAP---Proxy-SSL-WSS-soapui-project.xml].

Once the SoapUI project mocking the external service provider is imported:
# generate the key store 'external',
# configure your SoapUI to use SSL with mocked service 'ArticleServiceContinuationSoap11Binding-SSL-WSS MockService', and start it.

h3. Generate the key store 'external'

The key store 'external' containing the private/public key pair of the external service provider for SSL can be generated with the following command line:
{code}
keytool -genkey -alias soapui-external-service-provider -keyalg RSA -keypass keyextpwd \
-dname "CN=SSL External Service Provider, OU=Petals, O=Linagora, L=Grasse, ST=AM, C=FR" \
-storepass keystoreextpwd -keystore keystore-external.jks
{code}

h3. Configure SoapUI to use SSL with the mocked service provider

# In SoapUI, click *Preferences* on the main toolbar or select *File* > *Preferences* and switch to the *SSL Preferences* page.
# Enable SSL for Mock Services,
# Set the port 8089 for Mock Services secured by SSL,
# Set the key store file to used,
# Set the password of the key store, as well as the password for the key (even if you specified the same password when creating the keystore).

h3. Generate the key store 'Petals'

The key store 'Petals' containing the private/public key pair of the proxyfied service provider for SSL can be generated with the following command line:
{code}
keytool -genkey -alias petals-service-provider -keyalg RSA -keysize 2048 \
-dname "CN=SSL Proxyfied Service Provider, OU=Petals, O=Linagora, L=Grasse, ST=AM, C=FR" \
-storetype PKCS12 -storepass keystorepetalspwd -keystore /tmp/keystore-petals.pfx
{code}

h3. Configure SSL at Petals BC Soap level

Not only, SSL is configured at Petals BC Soap level, but also at service consumer level:
* at component level to inject the keystore configuration:
** `https-keystore-file`: The keystore file generated as described below,
** `https-keystore-password`: The keystore file password,
** `https-key-password`: the private key password.
* at service consumer level to define which transport (http, https or jms) must be used to expose the service provider.

h3. Running the use case

Launch a freshly installed Petals ESB:
{code}
~/petals-esb-default-zip-5.2.0/bin$ ./petals-esb.sh

Create a configuration file for the Petals BC Soap:
{code}
echo "httpsEnabled=true" >> /tmp/petals-bc-soap.cfg
echo "httpsKeystoreFile=/tmp/keystore-petals.pfx" >> /tmp/petals-bc-soap.cfg
echo "httpsKeystoreType=PKCS12" >> /tmp/petals-bc-soap.cfg
echo "httpsKeystorePassword=keystorepetalspwd" >> /tmp/petals-bc-soap.cfg
echo "httpsKeyPassword=keystorepetalspwd" >> /tmp/petals-bc-soap.cfg
{code}

Deploy Petals artifacts:
{code}
petals-cli.sh -c -- deploy -u mvn:org.ow2.petals/petals-bc-soap/5.0.1/zip --file /tmp/petals-bc-soap.cfg
petals-cli.sh -c -- deploy -u mvn:org.ow2.petals.samples.soap/sa-SOAP-samples-Proxy-SSL-WSS/5.0.1-1.0.0-SNAPSHOT/zip
{code}

Two services are exposed through HTTP (see http://localhost:8084/petals/services/listServices):
* {{ArticleServiceContinuation}}
* {{ArticleServiceContinuationSecuredByWSS}}

and 2 others through HTTPS (https://localhost:8083/petals/services/listServices):
* {{ArticleServiceContinuationSecuredBySSL}}
* {{ArticleServiceContinuationSecuredByWSSAndSSL}}

Use SoapUI to invoke your secured proxyfied service ! Sample requests are available into the SoapUI project.

h2. Securing a service running into Petals using 2-Way SSL and WS-Security

{tip}This use case runs with the Petals BC SOAP 5.0.0+. Its source code is available [here|https://svn.petalslink.org/svnroot/trunk/product/dev/prod/petals/petals-samples/petals-samples-soap].{tip}

The goal of this use-case is to show you that it is possible to mixed SSL and WS-Security to secure an internal endpoint as a webservice using several certificats:
* a transport certificate identifying the webservice client,
* a transport certificate to crypt the communication between the serveur and the client,
* a message certificate to sign the message sent by the client and to warranty its integrity,
* a message certificate to crypt the SOAP body content,
* a user name and a password to identify the user of the client,
* a time-stamp to avoid request re-injection.

So, it is needed to have the following key stores:
* a key store 'client': keystore-clt.jks (password: keystoreclt), containing:
** the private keys of the client,
** the public keys of the serveur
* a key store 'server': keystore-srv.jks (password: keystoresrv), containing:
** the private key used to crypt the SOAP body content,
** the public key of the client used to sign
* a specific key store 'ssl': keystore-srv-ssl.jks (password: keystoresrv), containing:
** the SSL private key of the server
** the SSL public key of the client

The private keys of the client (symetrically, public keys of the server) are:
* 'sslclt': the private key identifying the client at SSL level (2-way SSL), password: 'keystoreclt',
* 'wsseclt-sign': the private key to sign the message, password: 'keystoreclt'.

The private keys of the server (symetrically, public keys of the server) are:
* 'sslsrv': the private key to crypt the communication between the server and the client, password: 'pwsslsrv',
* 'wsseclt-crypt': the private key to crypt the message, password: 'keystoresrv'.

{tip}Although encrypted message is generated by the client, the private key is located on the server side.{tip}
{tip}To simplify the use-case, all keys are auto-signed.{tip}
{tip}The version of the SoapUI used as client needs to have keys with the same password than their keystore.{tip}

h3. About the service provider

A service provider 'Math' is available as a SoapUI mock at [http://localhost:8088/mockMathBinding?wsdl]. Just import the [SoapUI project|https://svn.petalslink.org/svnroot/trunk/product/dev/prod/petals/petals-samples/petals-samples-soap/sa-ssl-wss/src/main/resources/SOAP-with-SSL---WSS-soapui-project.xml] and start the mocked service 'mathBinding MockService'.

h3. Importing the service provider into Petals

Using the Petals Studio, create a service unit to deploy on the BC SOAP and provide the service 'Math'. You should have a service unit JBI descriptor as following:
{code:lang=xml}
<?xml version="1.0" encoding="UTF-8"?>
<jbi:jbi version="1.0"
xmlns:jbi="http://java.sun.com/xml/ns/jbi"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:petalsCDK="http://petals.ow2.org/components/extensions/version-5"
xmlns:soap="http://petals.ow2.org/components/soap/version-4"

xmlns:math="http://petals.ow2.org/samples/bc/soap/math">

<jbi:services binding-component="true">
<jbi:provides
interface-name="math:math"
service-name="math:mathService"
endpoint-name="autogenerate">

<soap:soap-version>1.1</soap:soap-version>
<soap:mode>SOAP</soap:mode>
</jbi:provides>
</jbi:services>
</jbi:jbi>
{code}

h3. Exporting the service provider outside Petals

Before to write the service unit that consume the internal service associated to the service provider 'Math', we need:
* to generate SSL, encryption and signature keys,
* to write the right WS-Policy.

h4. Creation of keys and key stores

h5. Creation of private keys

Open a command shell and go into the directory $PETALS_HOME/https. $PETALS_HOME/https is not a directory provided by Petals, it is used by this tutorial, so don't forget to create it manually.

* Creation and auto-sign of the private key 'sslclt':
{code}
keytool -genkey -validity 731 -keystore keystore-clt.jks -storepass keystoreclt -storetype JKS -keyalg RSA -alias sslclt -keypass keystoreclt -dname "CN=SSL Client, OU=Petals, O=Linagora, L=Nice, ST=AM, C=FR"
keytool -selfcert -validity 731 -keystore keystore-clt.jks -storetype JKS -storepass keystoreclt -alias sslclt -keypass keystoreclt
{code}

* Creation and auto-sign of the private key 'wsseclt-sign':
{code}
keytool -genkey -validity 731 -keystore keystore-clt.jks -storepass keystoreclt -storetype JKS -keyalg RSA -alias wsseclt-sign -keypass keystoreclt -dname "CN=WSSE Signature, OU=Petals, O=Linagora, L=Nice, ST=AM, C=FR"
keytool -selfcert -validity 731 -keystore keystore-clt.jks -storetype JKS -storepass keystoreclt -alias wsseclt-sign -keypass keystoreclt
{code}

* Creation and auto-sign of the private key 'wsseclt-crypt':
{code}
keytool -genkey -validity 731 -keystore keystore-srv.jks -storepass keystoresrv -storetype JKS -keyalg RSA -alias wsseclt-crypt -keypass keystoresrv -dname "CN=WSSE Encryption-In, OU=Petals, O=Linagora, L=Nice, ST=AM, C=FR"
keytool -selfcert -validity 721 -keystore keystore-srv.jks -storetype JKS -storepass keystoresrv -alias wsseclt-crypt -keypass keystoresrv
{code}

* Creation and auto-sign of the private key 'sslsrv':
{code}
keytool -genkey -validity 731 -keystore keystore-srv-ssl.jks -storepass keystoresrv -storetype JKS -keyalg RSA -alias sslsrv -keypass pwsslsrv -dname "CN=SSL Server, OU=Petals, O=Linagora, L=Nice, ST=AM, C=FR"
keytool -selfcert -validity 721 -keystore keystore-srv-ssl.jks -storetype JKS -storepass keystoresrv -alias sslsrv -keypass pwsslsrv
{code}

h5. Generation and export/import of public keys

* Export/Import of public key 'sslclt':
{code}
keytool -export -keystore keystore-clt.jks -storetype JKS -storepass keystoreclt -alias sslclt -file sslclt.crt
keytool -import -keystore keystore-srv-ssl.jks -storetype JKS -storepass keystoresrv -alias sslclt -file sslclt.crt
{code}

* Export/Import of public key 'wsseclt-sign':
{code}
keytool -export -keystore keystore-clt.jks -storetype JKS -storepass keystoreclt -alias wsseclt-sign -file wsseclt-sign.crt
keytool -import -keystore keystore-srv.jks -storetype JKS -storepass keystoresrv -alias wsseclt-sign -file wsseclt-sign.crt
{code}

* Export/Import of public key 'wsseclt-crypt':
{code}
keytool -export -keystore keystore-srv.jks -storetype JKS -storepass keystoresrv -alias wsseclt-crypt -file wsseclt-crypt.crt
keytool -import -keystore keystore-clt.jks -storetype JKS -storepass keystoreclt -alias wsseclt-crypt -file wsseclt-crypt.crt
{code}

* Export/Import of public key 'sslsrv':
{code}
keytool -export -keystore keystore-srv-ssl.jks -storetype JKS -storepass keystoresrv -alias sslsrv -file sslsrv.crt
keytool -import -keystore keystore-clt.jks -storetype JKS -storepass keystoreclt -alias sslsrv -file sslsrv.crt
{code}

h4. Writing the WS-Policy

The following WS-Policy contains assertions about our requirement:
* 2-Way SSL,
* and WS-Security with:
** authentication based on a timestamped username token,
** encryption of the body part,
** and signature of the body part.

{code:lang=xml}

{code}

h4. Creation of the consumer service unit

Using the Petals Studio, create a service unit to deploy on the BC SOAP and consume the internal service 'Math'.
Next update its JBI descriptor to add the right configuration about SSL and WS-Security:
{code}
<?xml version="1.0" encoding="UTF-8"?>
<jbi:jbi version="1.0"
xmlns:jbi="http://java.sun.com/xml/ns/jbi"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:petalsCDK="http://petals.ow2.org/components/extensions/version-5"
xmlns:soap="http://petals.ow2.org/components/soap/version-4"

xmlns:math="http://petals.ow2.org/samples/bc/soap/math">

<jbi:services binding-component="true">
<jbi:consumes
interface-name="math:math">

<!-- CDK specific elements -->
<petalsCDK:timeout>30000</petalsCDK:timeout>
<petalsCDK:mep xsi:nil="true" />

<!-- Component specific elements -->
<soap:service-name>MathServiceWithSSLAndWSS</soap:service-name>
<soap:mode>SOAP</soap:mode>
<soap:enable-http-transport>false</soap:enable-http-transport>
<soap:enable-https-transport>true</soap:enable-https-transport>

<soap:modules>rampart</soap:modules>
<soap:wss-policy>ws-policy.xml</soap:wss-policy>
</jbi:consumes>
</jbi:services>
</jbi:jbi>
{code}
where '{{ws-policy.xml}}' is the WS-Policy previously defined.

Add the class 'PasswordCallback' as password callback:
{code:lang=java}
public class PasswordCallback implements CallbackHandler {

public void handle(final Callback[] callbacks) throws IOException, UnsupportedCallbackException {

for (int i = 0; i < callbacks.length; i++) {
final WSPasswordCallback pwcb = (WSPasswordCallback) callbacks[i];
final String username = pwcb.getIdentifier();
if (username.equals("ssl-wss-client-username")) {
// Retrieve the password associated to the username of the UsernameToken
pwcb.setPassword("ssl-wss-client-password");
} else if (username.equals("wsseclt-crypt")) {
// Retrieve the password associated to the key used to encrypt
pwcb.setPassword("keystoresrv");
}
}
}
}
{code}

h3. Running the use case

Launch a freshly installed Petals ESB. Launch your SoapUI and start the mocked service.

Launch the script '{{deploy.sh}}' available [here|https://svn.petalslink.org/svnroot/trunk/product/dev/prod/petals/petals-samples/petals-samples-soap/sa-ssl-wss/src/main/scripts/deploy.sh] after to have adjusted the environment with '{{env.sh}}'.

Use SoapUI to invoke your secured service ! Sample requests are available into the SoapUI project.


h1. Complex Use Cases

These use cases involve several Petals components including the Petals-BC-SOAP component.
