Inject a file using #Resource and JNDI in JEE6 - glassfish

Question

Is it possible to inject a file using JNDI and #Resource in JEE6?
If so how do I setup and JNDI (file) resource in Glassfish?

Answer 1

If your objective is to configure a properties file as follows:
#Inject
#Resource("META-INF/aws.properties")
Properties awsProperties;
then you want to use a WELD extension which is explained in the WELD documentation here
It is as simple as adding this to your POM
<dependency>
<groupId>org.jboss.weld</groupId>
<artifactId>weld-extensions</artifactId>
<version>${weld.extensions.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
Otherwise
See this article for a programmatic approach.
Or else,
Store your properties in a DB schema table and use JPA 2.0 to retrieve them using JTA pointing to your JNDI.
Or if your application is a JSF one:
Add a resource bundle in the faces-config.xml file as follows:
<application>
<resource-bundle>
<base-name>/YourProperties</base-name>
<var>yourProperties</var>
</resource-bundle>
</application>
Add the corresponding YourProperties.properties file in your classpath or maven resources folder as follows:
In your container managed bean add the following snippet:
private String someString;
#PostConstruct
public void loadProperty(){
someString = ResourceBundle.getBundle("/YourProperties").getString("prop1");
}
