`<properties>`

Description:

Reads the properties file specified by LOCATION and registers its contents as request attributes visible to SUBTASKS.

Reagents:

Name	XPath	Description	Reagent Type	Expected Type	Required
CONTEXT	@context	Optional context from which missing elements of the LOCATION will be inferred if it is relative. The default is the value of the 'Attributes.ORIGIN' request attribute.	PHRASE	java.lang.String	No
LOCATION	@location	Optional location of a resource; if omitted, the value of the 'Attributes.LOCATION' request attribute will be used. LOCATION may be a filesystem path or a URL, and may be absolute or relative; if a relative value is provided, it will be resolved based on the value of CONTEXT.	PHRASE	java.lang.String	No
SUBTASKS	*	The set of tasks that are children of this task.	NODE_LIST	java.util.List	No

Examples:

Reads database connection information from a properties file, makes a connection, writes each name from the 'users' table to the screen:

 
       
        <properties location="build/WEB-INF/classes/properties/rdbm.properties"> 
          <sql-connection driver="${req(jdbcDriver)}" password="${req(jdbcPassword)}" url="${req(jdbcUrl)}" username="${req(jdbcUser)}"> 
            <sql-query> 
              <sql>SELECT user_name FROM users</sql>  
              <subtasks> 
                <echo>${req(1)},</echo> 
              </subtasks> 
            </sql-query> 
          </sql-connection> 
        </properties>
