The ITEM table stores the data related to the items while ITEM_MASTER stores the quantity in hand of each item.

Tools used

The tools used for developing and building the Inventory sample application are:

Apache Derby

Apache Derby, an Apache DB subproject, is a relational database implemented in Java. Its footprint is so small you can easily embed it in any Java-based solution. In addition to its embedded framework, Derby supports a more familiar client/server framework with the Derby Network Server.

Apache Maven 2

Maven is a popular open source build tool for enterprise Java projects, designed to take much of the hard work out of the build process. Maven uses a declarative approach, where the project structure and contents are described, rather than the task-based approach used in Ant or in traditional make files, for example. This helps enforce company-wide development standards and reduces the time needed to write and maintain build scripts. The declarative, lifecycle-based approach used by Maven 1 is, for many, a radical departure from more traditional build techniques, and Maven 2 goes even further in this regard. Maven 2 can be download from the following URL:

Configuring, building and deploying

Currently this sample application is available from our subversion repository, use the following svn command to retrieve the content:

svn co http://svn.apache.org/repos/asf/geronimo/samples/branches/2.1/samples/inventory/Image Removed inventory_home

A directory named inventory_home will be created when you check out from the source, you can choose a directory name and location convenient to you. We will generically refer to this directory as <sample_home>.

Configuring

Configuration of the application consists of creating the database and defining the connection pool to access it.

Creating and Populating Database

After starting Apache Geronimo log into the console and follow the given steps to create the InventoryDB database.

1. Select DB Manager link from the Console Navigation panel on the left.
2. Give the database name as InventoryDB and click Create button.
3. Select InventoryDB to the Use DB field.
4. Open InventoryDB.sql in the <sample_home>/inventory-ear/src/main/resources directory from a text editor.
5. Paste the content InventoryDB.sql to the SQL Commands text area and press Run SQL button.

CREATE TABLE item(
	item_id VARCHAR(10) PRIMARY KEY,
	item_name VARCHAR(25),
	description VARCHAR(100)	
);

CREATE TABLE item_master(
	item_id VARCHAR(10) PRIMARY KEY,
	quantity INTEGER
);

INSERT INTO item VALUES('001', 'Item 1', 'Test Item 1');
INSERT INTO item VALUES('002', 'Item 2', 'Test Item 2');
INSERT INTO item VALUES('003', 'Item 3', 'Test Item 3');
INSERT INTO item VALUES('004', 'Item 4', 'Test Item 4');


INSERT INTO item_master VALUES('001', 12);
INSERT INTO item_master VALUES('002', 8);
INSERT INTO item_master VALUES('003', 49);
INSERT INTO item_master VALUES('004', 34);

Building

Inventory application comes with an pom.xml script to help users to build from source code. Use the command prompt to navigate into the inventory directory and just give mvn install command to build. It will create the inventory-ear-2.1-SNAPSHOT.ear file under the <sample_home> directory. Now, you are ready to deploy Inventory web application in to the Geronimo Application server.

Deploying

Deploying sample application is pretty straight forward as we are going to use the Geronimo Console.

1. Click the Deploy New link on the Console Navigation panel.
2. Load inventory-ear-2.1-SNAPSHOT.ear file from <sample_home> directory into the Archive input box.
3. Press Install button to deploy the application in the server.

Testing of the Sample Application

...

The user can directly access Add Items, Receive Goods and Issue Goods functionalities from the Welcome page.
