To configure an external PID minter, create a Spring bean configuration file using the HttpPidMinter class, and use a system property to use it instead of the internal PID minter:

-Dfcrepo.spring.minter.configuration=file:///path/to/minter.xml -Dfcrepo.minter.username=minterUser -Dfcrepo.minter.password=minterPass

Example minter.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:c="http://www.springframework.org/schema/c"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

    <bean class="org.fcrepo.kernel.identifiers.HttpPidMinter"
        c:url="http://localhost/my/minter" c:method="POST"
        c:username="${fcrepo.minter.username:minterUsername}"
        c:password="${fcrepo.minter.password:minterPassword}"
        c:regex="" c:xpath="/response/ids/value"/>

</beans>

The properties that can be set are:

• url (required): The URL of the external minter REST service.
• method: The HTTP method to use to generate a new identifier: GET, POST, or PUT.  If not specified, POST is used.
• username/password: The username and password to use for connecting to the minter REST service.  You may want to pass the username/password using System properties instead of hard-coding them in the config file (the example above shows how to use a System property with a fallback value if the property is not set).  If not specified, no authentication is used.
• regex: If set, remove text matching the regular expression from the minter service response.  For example, if the minter response is "id: foo/abc123", the regular expression ".*/" would remove the "id: foo/" and result in the identifier "abc123".
• xpath: If set, parse the minter service response as XML and use XPath to get the identifier value to use.
