Body
I have a bunch of Spring beans which are picked up from the classpath via annotations, e.g. <pre><code>@Repository("personDao") public class PersonDaoImpl extends AbstractDaoImpl implements PersonDao { // Implementation omitted } </code></pre> In the Spring XML file, there's a <a href="http://static.springframework.org/spring/docs/2.5.x/api/org/springframework/beans/factory/config/PropertyPlaceholderConfigurer.html" rel="noreferrer">PropertyPlaceholderConfigurer</a> defined: <pre class="lang-xml prettyprint-override"><code><bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="location" value="/WEB-INF/app.properties" /> </bean> </code></pre> I want to inject one of the properties from app.properites into the bean shown above. I can't simply do something like <pre class="lang-xml prettyprint-override"><code><bean class="com.example.PersonDaoImpl"> <property name="maxResults" value="${results.max}"/> </bean> </code></pre> Because PersonDaoImpl does not feature in the Spring XML file (it is picked up from the classpath via annotations). I've got as far as the following: <pre><code>@Repository("personDao") public class PersonDaoImpl extends AbstractDaoImpl implements PersonDao { @Resource(name = "propertyConfigurer") protected void setProperties(PropertyPlaceholderConfigurer ppc) { // Now how do I access results.max? } } </code></pre> But it's not clear to me how I access the property I'm interested in from <code>ppc</code>?

1. COI've asked essentially the same question, although in a slightly different scenario: http://stackoverflow.com/questions/310271/injecting-beans-into-a-class-outside-the-spring-managed-context. So far, no one has been able to answer it.

2. COPlease note that as of Spring 3.1, `PropertyPlaceholderConfigurer` is no longer the recommended class. Prefer `PropertySourcesPlaceholderConfigurer` instead. In any case, you can use the shorter XML definition `<context:property-placeholder />`.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
