A product configuration file, or in shorter form a product, defines the configuration of your Eclipse application, e.g. icons, splash screen and which plug-ins or features are included in your application.
The product is a development artifact which describes the content of your application and is not required at runtime.

It is possible to enter an ID for the product. Avoid using the same ID for the product as for a plug-in as this might create problems during a product export. Convention is to add the .product extension to the ID.
A product can either be based on plug-ins or on features. This setting is done on the Overview tab of the product configuration file.
On the Dependency tab you maintain the plug-ins or features your products consists of. A product does not perform automatic dependency resolution. If you add a feature to your product and want to add its dependencies, press the Add Required button.

Here you can specify the file name of the launcher and the icon which should be used. Make sure the format of the icons is correct, otherwise Eclipse will not use them.
The icon configuration depends on the platform you are using. Eclipse allows you to export your application for multiple platforms and uses the correct ones based on your product configuration.
In the Launching Arguments section you can specify parameters for your Eclipse application and arguments for the Java runtime environment. Program Arguments are parameters passed to the Eclipse application.
The relevant sections are highlighted in the following screenshot.
Your product configuration file can be used to export your application to run outside of Eclipse.
Exporting your product creates a folder with all required artifacts to run your application. This includes a native launcher specific to the platforms, e.g. Windows or Linux, you have exported it for.

export the product as an archive file.
The resulting directory can be for example compressed (zipped) and shared with others. The export dialog allows you to create an archive file directly, which makes it easier to transfer all files to another machine.
If you transfer the content of this directory to another machine (with the same architecture, e.g. Linux 64 bit) your application can start on this machine. Of course the correct Java version must be installed there.

Eclipse adds the compiled Java classes by default. You have to add other files manually, e.g. icons or splash screen images.

A headless build is an automatic build without user interaction and without a graphical user interface. It can be triggered from the command line. Typically the build is automatically done via an additional software component called the build server which does so in a clean (and remote) environment.
An example for a build server would be the Jenkins continuous integration (system). See the online Jenkins tutorial for an introduction into the setup, configuration and usage of Jenkins.
Several solutions exists for building Eclipse RCP applications via a headless build. Currently the most popular approach is based on Apache Maven. See the online Maven Tycho tutorial for an introduction into headless builds for Eclipse RCP applications.

If you add files outside of the Eclipse IDE, you need to Refresh (via F5) your project in the Project Explorer view, to see the file in Eclipse.
Afterwards your project should look like the following screenshot.
The file name and the location of the file must be correct otherwise Eclipse will not use your splash screen.
On the Splash tab of your product configuration file, define that your application plug-in contains the splash screen.
Verify that the splash is displayed if you start your application from the Eclipse IDE.
Configure that the
file is included into the exported application by adding it to the
file of your application plug-in.
Export your product again and ensure that the splash screen is also shown if you start the exported application. Make sure that the target directory of the export is empty before you start the export.
The Eclipse export defaults the launcher for your Eclipse RCP application to eclipse, e.g. on Windows to eclipse.exe.
Change this launcher name to mywizard on the Launching tab of your product configuration file.
Export your product again and validate that the launcher name has changed.

All four features are required to start your application. Assure you start via the product and not with an existing launch configuration to ensure that your new product configuration is used.
Test that your application starts from the Eclipse IDE. Afterwards export is again into an empty directory and ensure that it starts also as exported application.
The most common problem is that the folder to which you export is not empty. If you export to a certain folder, ensure that the folder is empty. Exporting twice to the same folder may create file locks or results in error messages reporting version conflicts.
If the export encounters a problem please have a look into the following table for a solution:
Table 1. Problems with the product export
|Export fails||Try using an empty target directory, sometimes the export cannot delete the existing files and therefore fails.|
|No executable file after the export||Check the flag "The product includes native launcher artifacts" in your .product file on the Overview tab.|
|Product could not be found||Validate that all dependencies are included in the product. Delete an existing launch configuration and restart the product from the IDE to see if everything is configured correctly.|
|Splash screen or other icons are missing||
|Splash screen is missing||Ensure that you have entered the defining plug-in in the "Splash" tab on the product configuration file. If this is not set, the splash screen is not displayed after the export. Unfortunately, it is displayed if you start the plug-in from the Eclipse IDE.|
|Issues during startup||Check the log file in the workspace folder of your exported application to see the error messages during startup. Alternatively add the "-consoleLog" parameter to the ".ini" file in folder of the exported application.|
