Application is failing to load the values from properties file.

[NayaganRaj]

Hi,

I am using maven for packaging my application.

My springldap.xml has

<bean id="propertyPlaceHolderPMSServices"
class="org.springframework.beans.factory.config.Pr opertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:settings.properties</value>
</list>
</property>
</bean>

<bean id="contextSource"
class="org.springframework.ldap.core.support.LdapC ontextSource">

<property name="url" value="${ldap.host}" />
</bean>

I have placed the settings.properties under classpath..But my application is failed to set the values for url property ...instaed it is setting ${ldap.host} as value for url.

My application throws :
org.springframework.ldap.UncategorizedLdapExceptio n: Uncategorized exception occured during LDAP processing; nested exception is javax.naming.NamingException: Cannot parse url: ${ldap.host}

Please advice on the possible mistakes I must be doing at my workspace..

A common mistake is to use BeanFactory instead of ApplicationContext, without realizing what BeanFactory doesn't do for you. To quote the Spring reference manual:

It is important to know that a BeanFactory treats bean post-processors slightly differently than an ApplicationContext. An ApplicationContext will automatically detect any beans which are deployed into it which implement the BeanPostProcessor interface, and register them as post-processors, to be then called appropriately by the factory on bean creation. Nothing else needs to be done other than deploying the post-processor in a similar fashion to any other bean. On the other hand, when using plain BeanFactories, bean post-processors have to manually be explicitly registered [...]

You probably have code that looks something like this:

Resource res = new ClassPathResource("/springldap.xml");
BeanFactory context = new XmlBeanFactory(res);

If you want to have the PropertyPlaceholderConfigurer registered for you, write this instead:

ApplicationContext context = new ClassPathXmlApplicationContext("/springldap.xml");

Hi Ulsa,

Thanks..

Using ApplicationContext context = new ClassPathXmlApplicationContext("/springldap.xml"); loads all the beans mentioned in the xml.
