Introduction

This guide will outline required steps needed to get a GWT application working with OFCGWT. Basic Java and GWT programming skills will be assumed, and that you are familiar with using Eclipse as your development environment. Note: whilst using Eclipse is assumed, instructions should work generically for any other kind of development environment

Requirements

The following items are what is required to be successful with OFCGWT (though earlier version might work, they have not been tested).

To begin you will need...

• GWT 1.5.2
• Java 1.6
• OFCGWT 1.0.1
• Eclipse 3.4

The 5 Major Steps

1. Create an Eclipse GWT Project

Unless you know what you are doing, copy the project names etc exactly as provided.

a) Using GWT tools at the command line, create a new GWT project ProjectCreator -eclipse ofcgwttest -out ofcgwttest

b) Still with GWT tools command line, create a new GWT application ApplicationCreator -eclipse ofcgwttest -out ofcgwttest com.gwttest.client.Test

c) Remove/delete the two .cmd files created by GWT in the project root directory - we won't be using these and they will only confuse things going forward.

These two steps will have created a new Eclipse project setup for GWT.

2. Copy Files from OFCGWT Download

To speed things up, we are going to copy in a java source file provided with the 1.0.1 download of OFCGWT.

a) Copy the Test.java file included in the beta6.zip file into the ofcgwttest\src\com\gwttest\client directory overwriting the existing file.

b) Now copy in the ofcgwt.jar file into the root of the project directory ofcgwttest\

3. Import and Add OFCGWT Jar

Ok, this is the biggest step, so follow closely...

a) Launch Eclipse and close all other projects - they will only confuse things.

b) Import the project File->Import then under General->Existing Projects into Workspace - then find the project root for ofcgwttest and then Finish. You should have a project with compile errors - that is ok as we haven't included the jar file.

c) Expand the ofcgwttest project in eclipse and find the ofcgwt.jar file - Right click and choose Build Path->Add to Build Path. This should remove the compile errors and the project is almost ready.

d) Now add the OFCGWT module to the test gwt module xml file. Within the project, find the Test.gwt.xml file under src/com.gwttest/public - edit this file and add <inherits name='com.rednels.ofcgwt.OFCGWT'/> after the <!-- Other module inherits section.

4. Configure Launch

We need to modify the GWT included eclipse launch file to ensure the shell has a path to the OFCGWT jar file.

a) Select the Eclipse menu Run->Run Configurations. You should see Test listed on the left hand side - select it.

b) Under the Classpath tab, select the User Entries and then click Add JARs. Choose the ofcgwt.jar file and OK.

5. Have Fun!

We are finished - you should be able to run the launch file and the shell will show the a OFCGWT demo
