How to use JndiPropertySource?

Question

We are trying to convert our WebApp to complete configuration using a JndiPropertySource(for all parameters that are environment dependent).

Has anyone a example usage of it (maybe even for tomcat)?

We already get the DataSource via JNDI, so we want the HibernateDialect to be configured right besides it...

Answer 1

In your spring-context.xml you need only the placeholder tag:

<context:property-placeholder />

After that you insert an environment tag in Tomcats main context.xml, it reads it:

<Environment name="hibernate.dialect" 
            value="org.hibernate.dialect.Oracle10gDialect" 
             type="java.lang.String" 
         override="false"/>

Now you can use the code ${hibernate.dialect} in the sprinng config file.
