    Default Spring Bean Value

    Okay, so we have an application that uses Spring 2. I have a bean that accesses a method which returns a username (process ID) and password to be used in a database connection. The problem I am having is retrieving those values. Spring 2 seems to want to return the literal values for the property values (ie. #{pid.username} instead of the value of username). Here is what I have...

            <bean id="pidReader" class="com.blah.biz.securepid.DefaultPIDReader" />
     
    	<bean id="pid" factory-bean="pidReader" factory-method="readPIDCredentials">
    		<constructor-arg value="arg" />
    	</bean>
     
    	<bean id="datasource" class="org.apache.commons.dbcp.BasicDataSource">
    		<property name="username">
    			<value>#{pid.username}</value>
    		</property>
    		<property name="password">
    			<value>#{pid.password}</value>
    		</property>
    		<property name="driverClassName">
    			<value>driver</value>
    		</property>
    		<property name="url">
    			<value>url</value>
    		</property>
    	</bean>

    The DefaultPIDReader class is located in a library that is referenced by the main app. This works fine for the apps that are running Spring 3. Is there any way in Spring 2 to return the value of pid.username. Someone mentioned using the util namespace, but I cannot find anything that works. And upgrading to Spring 3 (on this app anyway) is not an option.

    Default Re: Spring Bean Value

    Found the solution. If using Spring 3, <value>#{username}</value> works. If using Spring 2, <util:property-path path="bean.username"/> is equivalent.
