In the ensuing window, click on the Web Server icon: Click the choose folder button, and select the work folder. Under Options, check the box next to "Automatically show index. Then stop and restart the server by sliding the toggle labeled "Web Server:

To take advantage of this, you need to configure a JDBC Java Database Connectivity data source for the server which your application can use for connection pooling.

You could configure the data source directly within the GlassFish server Admin Console, or, as described below, you can declare the resources that your application needs in a glassfish-resources.

When the application is deployed, the server reads in the resource declarations, and creates the necessary resources.

The following steps demonstrate how to declare a connection pool, and a data source that relies on the connection pool. Optionally, add a description for the data source. For example, type in: Click Next, then click Next again to skip step 3, Additional Properties.

Make sure the Extract from Existing Connection option is selected, and choose jdbc: The wizard detects any database connections that have been set up in the IDE. Therefore, you need to have already created a connection to the MyNewDatabase database at this point. In Step 5, select javax.

Note that the IDE extracts information from the database connection you specified in the previous step, and sets name-value properties for the new connection pool. The wizard generates a glassfish-resources. In the Projects window, you can open the glassfish-resources.

The server starts up if not already running, and the project is compiled and deployed to it. Note that the new data source and connection pool are now displayed: Referencing the data source from the application You need to reference the JDBC resource you just configured from the web application.

Deployment descriptors are XML-based text files that contain information describing how an application is to be deployed to a specific environment. For example, they are normally used to specify application context parameters and behavioral patterns, security settings, as well as mappings for servlets, filters and listeners.

In the Projects window, expand the Configuration Files folder and double-click web.

Click the References tab located along the top of the editor. The Description field is optional, but you can enter a human-readable description of the resource, e. The new resource is now listed under the Resource References heading.

To verify that the resource is now added to the web. Select the GlassFish server in the left pane. Before you close the Servers manager, make a note of the path indicated in the Domains folder text field.

When you connect to the GlassFish server in the IDE, you are actually connecting to an instance of the application server. Each instance runs applications in a unique domain, and the Domain Name field indicates the name of the domain your server is using.

As shown in the image above, the driver JAR file should be located within domain1, which is the default domain created upon installing the GlassFish server.

Click Close to exit the Servers manager. If you do not see the driver JAR file, perform the following step. Deploy your project to the server.In this series, we'll be using Python, Flask and MySQL to create a simple web application from scratch.

It will be a simple bucket list application where users can register, sign in and create their bucket list. This tutorial assumes that you have some basic knowledge of the Python programming language. We'll be using Flask, a Python web application framework, to create our application.

So, let us proceed to write a simple Jersey Application which will expose a web service method to display the list of users.

Chapter 3 Getting Started with Web Applications. A web application is a dynamic extension of a web or application server. Web applications are of the following types: Presentation-oriented: A presentation-oriented web application generates interactive web pages containing various types of markup language (HTML, XHTML, XML, and .
