The library does require that a configuration scheme is chosen - in beans.xml as described below.

+ *

But the library does NOT impose any mandatory parameters in order to start up (except for those required for + * bootstrapping the configuration). The library does know of certain parameters, if it encounters them. + * + *

The known parameters are TYPE (service type) PAZPAR2_URL, SERVICE_ID, and SERVICE_PROXY_URL

+ * + *

The built-in configuration schemes are:

+ * + * + *

It must be determined deploy-time what configuration scheme to use, by selecting the preferred + * mechanism in the application's beans.xml. In this example the MasterKey configuration scheme is injected:

+ * + * 
+ * <beans xmlns="http://java.sun.com/xml/ns/javaee"
+ *         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+ *         xsi:schemaLocation="
+ *     http://java.sun.com/xml/ns/javaee 
+ *     http://java.sun.com/xml/ns/javaee/beans_1_0.xsd">  
+ *     <alternatives>         
+ *        <class>com.indexdata.mkjsf.config.Mk2ConfigReader</class>
+ *        <!-- Options                      Mk2ConfigReader     -->
+ *        <!--                              WebXmlConfigReader  -->        
+ *     </alternatives>          
+ * </beans>
+ *
+ * + *

For the web.xml configuration scheme (choosing WebXmlConfigReader in beans.xml) + * to pre-define the URL of the Pazpar2 to use, the configuration could be:

+ * + * 
+ *  <context-param>
+ *   <param-name>PAZPAR2_URL</param-name>
+ *   <param-value>http://localhost:8004/</param-value>
+ *  </context-param>
+ *
+ * + *

For the Mk2ConfigReader scheme to work, the web.xml must then contain pointers to the configuration directory + * and properties file. + * In this example the configuration directory is in the web application itself (war://testconfig). A more regular + * example would put it in a separate directory to not have it overwritten by each deployment of the war.

+ * 
+ * <context-param>
+ *  <param-name>MASTERKEY_ROOT_CONFIG_DIR</param-name>
+ *  <param-value>war://testconfig</param-value>
+ * </context-param>
+ * <context-param>
+ *  <description>
+ *   The sub directory to hold config file(s) for this Masterkey component.
+ *  </description>
+ *  <param-name>MASTERKEY_COMPONENT_CONFIG_DIR</param-name>
+ *  <param-value>/jsfdemo</param-value>
+ * </context-param>
+ * <context-param>
+ *  <param-name>MASTERKEY_CONFIG_FILE_NAME</param-name>
+ *  <param-value>jsfdemo.properties</param-value>
+ * </context-param>
+ * <context-param>
+ *  <description>
+ *   Defines the lifespan of configuration parameters as retrieved
+ *   from the file pointed to by MASTERKEY_CONFIG_FILE_NAME.
+ *   Can be SERVLET (cached) or REQUEST (read for every request).
+ *   Will default to SERVLET.
+ *  </description>
+ *  <param-name>MASTERKEY_CONFIG_LIFE_TIME</param-name>
+ *  <param-value>REQUEST</param-value>
+ * </context-param>
+ *
+ * + *

The jsfdemo.properties file might look like this for running against a + * local Pazpar2 service:

+ * + * pz2client.PAZPAR2_URL = http://localhost:8004/ + * + *

Some of the other know parameters in this format could be:

+ * + * 
+ * service.TYPE = SP              
+ * proxyclient.SERVICE_PROXY_URL = http://localhost:8080/service-proxy/
+ *
+ * + *

It's possible to implement a custom configuration scheme by either ignoring whatever scheme is + * injected and then applying the required values otherwise, OR by extending the ConfigurationReader + * and inject that class in beans.xml instead of any of the two predefined options. The extended + * class must construct a Configuration object -- which is basically a set of key-value pairs -- + * and then set the desired values and hand it off to the Configurable (currently Pz2Service, Pz2Client, + * ServiceProxyClient

+ * + *

Finally it's possible to set the URL runtime even from the UI pages.
