Overview

The Java Network Launch Analyzer (JaNeLA) is a tool designed to check aspects of the JNLP file(s) and resources intended for the JWS based launch of a rich-client Java application.

In addition to checking the well-formedness and validity of the XML, a variety of other checks are performed. These checks include

• The encoding and content-type.
• The availability and declared size of resources.
• The types of downloadable resource (e.g. GIF/JPEG for icon elements, .jar for jar and nativelib elements).
• ...

For the complete list of checks currently performed, consult the JaNeLA check table. The tests listed in table rows that have a 'checked' checkbox have been implemented, the unchecked rows are either 'ToDo', or still under review.

Download

The current binary can be obtained as janela.jar.

File Menu

The File menu contains three items.

• Open File. Offers a file chooser to select a main/applet JNLP file in the the text area of the 'Main JNLP' tab. JaNeLA will automatically analyze the file for errors, warnings and optimizations and list those below. Attempts will be made to load any dependant JNLP extensions, in subsequent tabs, until all resources needed for the launch are loaded and analyzed.
• Open URL. Does the same as above, starting with an URL.
• Exit. Exits the application.

Report Menu

The Report menu has a single item - Text Report. This report summarizes the list of errors, warnings and (possible) optimizations for the JNLP files in all open tabs. This should represent the main JNLP as well as any extension referenced by the main JNLP or an extension.

• Help on usage. This page!
• Help on errors. Help on the messages provided in the list and report.
