Welcome to the trailmaps. The trailmaps are hands-on, step-by-step guides to creating services and applications on NetKernel.

The trailmaps can generally be followed in any order but if you are new to NetKernel it is recommended that you start with the Hello World Service.

The Basics:

• Hello World Service - using the supplied workbench module you create a simple service and execute it from your web browser.
• My First Module - from absolute first principle you create a module, populate it with a simple service and then deploy it.
• Text 2 Image - learn about parameter passing, calling sub-services and exception handling.
• DPML by Example - a humorous trip through the world of declarative development (though not strictly a trailmap it is worthy of a mention here)
• Scripting - learn about creating services with procedural scripting languages such as beanshell, groovy, javascript and python.
• Asynchronous processing - learn about issuing asychronous requests between services.

Use-cases and Technologies:

• Batch Processing - an example of batch processing of documents on the filesystem.
• Native Process Pipelines - an example of combining commandline tools into NetKernel pipelines.
• Dynamic Image Generation - an example of using pipelines to sequence image processing operations
• PDF Distilling - an example of the intray transport asynchronously pulling files from a directory to distill to PDF.
• Database backed Application - a complete multipage application backed by a relational database.
• SOAP Service and Client - an example service and client which exchange a sequence of messages.
• Email processor - an example of a service which sends and receives emails.
