How To Get Services Tab Show Up On Left Side Of Netbeans

The goal of this exercise is to create a project and generate entity classes and RESTful web services from a database.

This section uses the JavaDB (Derby) database and the jdbc/sample data source. JavaDB is included with the SDK. The jdbc/sample data source is generated by NetBeans IDE automatically when y'all install the IDE together with GlassFish.

Creating the Project

To create RESTful spider web services, you need a Coffee Web application project.

*To create the project: *

Choose File > New Projection (Ctrl-Shift-N on Linux and Windows, ⌘-Shift-N on MacOS). Nether Categories, select Java Web. Under Projects, select Spider web Application. Click Side by side. The New Spider web Awarding magician opens.

Alternatively, you can create a Maven Web Application. Choose File > New Project (Ctrl-Shift-N on Linux and Windows, ⌘-Shift-N on MacOS). Under Categories, select Maven. Nether Projects, select Maven Web Awarding and click Next.

Under Project Proper name, enter CustomerDB . Click Adjacent.

Select either Coffee EE 6 Web or Java EE 7 Web. Under Server, select the server you want to use, but note that Java EE projects require GlassFish server 3.x or 4.10. Click through the remaining options and click Cease.

Of import for Maven Projects: In NetBeans IDE seven.2 yous cannot gear up the server when you create a Maven web application. Nevertheless, you need to set the server before you can create a persistence unit. Therefore, after you create the Maven spider web application, open up the project's Properties and set the server in the Run backdrop. To open the project's Backdrop, right-click on the Project node and select Properties from the context bill of fare.

Generating Entity Classes and RESTful Services

When yous have a Java web awarding, add together entity classes and RESTful web services to the projection.

*To generate entity classes and RESTful web services: *

Right-click the CustomerDB node and choose New > Other > Web Services > RESTful Spider web Services from Database. The New RESTful Spider web Service sorcerer opens, on the Database Tables panel.

In the Database Tables panel, if you are using the GlassFish server, select the jdbc/sample information source from the Data Source driblet-down field.

If y'all are using Tomcat, select jdbc:derby://localhost:1527/sample. If the Derby database server does not start automatically, you demand to start information technology from the Databases tab in the Services window.

Notation for MySQL users: You have to create a new data source. Select New Data Source, give it an arbitrary descriptive name, and select the jdbc:mysql://localhost:3306/sample database connexion. You created this connection when you lot created the sample database on MySQL.

Under Available Tables, select CUSTOMER and then click Add together. The DISCOUNT_CODE table, which has a human relationship with the Client table, is also automatically added to the Selected Tables list. If you are using a MySQL database or some versions of Derby, the MICRO_MARKET table is also added. You now see the following (Derby version):

Click Adjacent. The Entity Classes page opens. Type entities for the Package name. You now meet the post-obit (Derby version).

Annotation: The RESTful Spider web Services from Database sorcerer automatically generates JAXB annotations. If you lot generate entity classes for a Coffee EE application with the Entity Classes from Database wizard, and you might later want to create RESTful web services from those entity classes, make sure the Generate JAXB Annotations box is checked. You tin can also add JAXB annotations by hand to entity classes earlier running the RESTful Spider web Services from Entity Classes magician. For more data, see NetBeans to Generate Simpler RESTful Web Services.

entity classes

Click Next. A panel opens in which you lot can set the name and location of generated service classes and packages. For Java EE projects, yous have the option of changing the name and location of the REST application configuration course.

For this tutorial, accept the defaults and click Terminate. When you click Finish the IDE generates entity and service classes. In an Java EE project, the IDE also generates an application configuration course, which is a subclass of Application.

The IDE now generates the RESTful web services. When the IDE is finished, expect in the Projects window. The generated entity classes are in the entities parcel and services are in the service parcel. Java EE RESTful web services from a database instantiate EntityManager in each service class. This removes the need for JPA controller classes and generates simpler code.
