While it previously defaulted to org. H2Platform, which is the qualified name of an internal implementation class, it is now possible to use the following properties to define the type of database to connect to:. Note: unblu still supports the ability to define the internal class name of the Platform like the previous default, above, with the H2Platform.
Unblu 7 latest Unblu 6 Unblu 5 Unblu 4. Standardizes the configuration of database connections. Allows more fine grained control over database connection pooling settings Disadvantages of using JNDI Configuration split into two pieces. Unblu configuration only points to separate configuration of the app server.
Forgetting to setup the app server's configuration properly lets unblu fail at times. Admin Configuration Items Two properties as above must also be enabled for the 'Admin' connection. Adapt the context. This is so that the driver can be accessed automatically at runtime. On each server startup or application reloading, all relevant objects are re-bound to the namespace. Lifecycle listener modules provide a means of running short or long duration tasks based on Java technology within the GlassFish Server environment, such as instantiation of singletons or RMI servers.
These modules are automatically initiated at server startup and are notified at various phases of the server life cycle. For details about lifecycle modules, see Developing Lifecycle Listeners. The initial JNDI naming context is not available until server initialization is complete. InitialContextFactory interface. For details, click the Help button in the Administration Console.
To create an external JNDI resource, use the asadmin create-jndi-resource command. A custom resource specifies a custom server-wide resource object factory that implements the javax.
ObjectFactory interface. To create a custom resource, use the asadmin create-custom-resource command. Template glassfish-resources. Create a property in the custom resource for each setter method in the JavaBean class. For example, if the JavaBean class has a method named setAccount , specify a property named account and give it a value.
PropertiesFactory , then specify one or both of the following:. Create a property in the custom resource named org. The path can be absolute or relative to as-install. The file must be accessible to the GlassFish Server. Create the desired properties directly as properties of the custom resource. If both the fileName property and other properties are specified, the resulting property set is the union. If the same property is defined in the file and directly in the custom resource, the value of the latter takes precedence.
Create a property in the custom resource named value and give it the value needed by the application. For example, If the application requires a double of value Active Oldest Votes. When it is used? Applications don't have to change as they migrate between environments. You can minimize the number of folks who need to know the credentials for accessing a production database. Improve this answer.

It is safer, and more standardized, thus makes deployment easier no need to guess what the name of the properties file must be etc. What then the difference between using environment variables and JNDI? Is it similar concept? Lucky Aniket Thakur Aniket Thakur 61k 35 35 gold badges silver badges bronze badges. DataSource, javax. Connection-Factory, javax.
