NetUI Project Template


NetUI enabled web applications require a set of JARs, XML configuration files, and web.xml entries. In order to make it easy to get started with a NetUI web application, the samples/netui-blank project template is available in the Beehive distribution. Use this as a starting point for building new NetUI-enabled applications. This document describes how to build a new NetUI-enabled application from the netui-blank project template.

In the documentation below, <beehive-root> refers to the top-level directory of your local Beehive installation. A typical value for <beehive-root> would be /apache/apache-beehive-1.0.

Using the NetUI Webapp Template

The following instruction assume that you have completed all of required and optional steps in the Beehive set up procedure at Installation and Setup.

To use the netui-blank template, follow these steps:

Create a New Webapp

A new NetUI web project can be created by running the following Ant command from <beehive-root:

ant -f beehive-imports.xml new.netui.webapp

This will prompt you for a fully-qualified path for your web project. For example, the following path /projects/fooWeb would create a project layout similar to that described here. This project will include the runtime, configuration files / entries, and a basic Ant build.xml file. The description below assumes that you have created the NetUI-enabled web project fooWeb under a projects/ directory.

Configure the Webapp's Build Properties

In this section you will edit the build.properties file in order to set build-related paths and values for your web project.

Open the file /projects/fooWeb/build.properties in a text editor and edit the following properties:

  • Set the beehive.home property to point to the top-level folder of your Beehive installation.
  • Set the context.path property to some value that is appropriate to your web application. This value is used when the web-project is built into a .war archive. When deploying the .war archive, it also often determines thecontext path for the web project when deployed to the server.

For example, if Beehive is installed at /apache/apache-beehive-1.0, and you created a project named fooWeb then your build.properties file might appear as follows:



Properties files should use the '/' character to separate drive, directory, and file names.
This .properties file also assumes that you are using Tomcat as your Servlet container. If you are not using Tomcat, set the paths to the Servlet and JSP API classes appropriately for your container. In some cases, these may point to the same JAR.

Build the Webapp

By default, the build associated with a new NetUI-enabled webapp stores the Ant build.xml file in the project's root directory; in the example above, this is the projects/fooWeb directory.

To build the webapp, run ant build. This will create a build/ directory into which the webapp's resources are copied and Java source files are compiled. This build directory will be archived when creating a .war file. It can also be deployed, exploded directly to the server.

To clean the webapp, run ant clean.

To create a .war file, run ant war.

To update the JSPs when doing iterative development, run ant copy.jsps.

Deploy and Run the Webapp

If you are using Tomcat, the web application can be deployed by copying the built .war file from projects/fooWeb/fooWeb.war to Tomcat's webapps directory.

If you are using a different Servlet container, follow your container's deployment instructions for deploying a .war web projct arcive.

Once the web application is deployed, you can run your web application by accessing the following URL from a browser: http://localhost:8080/fooWeb/ . You should see a page with the text "New Web Application Page".
