Jetfire Overview Jetfire is a dynamic, multi-user, object oriented language and runtime support. The language derives its syntax from C# and Java. Jetfire extends this syntax by adding first class support for features such as states , roles , versioning, audit information and persistence . Objects and classes ( code ) in Jetfire are automatically and transparently placed in permanent storage on a server nexus . This storage can either be a file system, memory(sandbox applications) [...]
Find Workflows
Displaying Jetfire Workflows in the GUI
Workflows come in all 'shapes and sizes'. Jetfire Administrators need to easily identify what workflows should be displayed to Jetfire Users for different applications. This page describes how to configure Web Parts to display workflows. The figure to the right shows the properties that are used to Find Workflows used in a Web Part. This is used as standard input. Jetfire Find Workflow Criteria [...]
Overview In Jetfire a 'workflow' refers to a workflow object. A Jetfire 'workflow' is an instantiation of a ' Workflow Class '. Jetfire workflow classes have a number of unique first class attributes such as persistence, dynamic access modifiers , and states . A workflow object at its heart is still a standard OO object that describes data [...]

Jetfire First Class Constructs Jetfire at its heart is an OO language based heavily on C# and Java. Jetfire does have a number of first class constructs that traditional object oriented languages (such as C#) do not have. These constructs provide Jetfire with its unique capabilities. They include: Object and Class Persistence : Jetfire objects and classes (code) are persistent . They are automatically serialized and stored in a workspace or namespace [...]
Jetfire API for Web Service (return to Jetfire Web Service ) An xml string provides a lot of flexibility in responding to client requests. The Server can send one or more workflows or an error message. Of course, xml can also be complicated to decode. The Jetfire API also contains access to the Jetfire Web Service. TrackerRealm provides a dll that customers can integrate into their Visual Studio projects. Start-up
The utility is started up by instantiating the JfWS class. When [...]
Role Overview A 'Role' is a first class workflow object within Jetfire. Roles provide the logged-in user with permissions for accessing workflows, workspace contents, executing methods, accessing properties and changing permissions. A Jetfire user can be assigned one or more roles. Methods and properties objects can have roles assigned using the 'access construct' . Workflow objects can be assigned roles programmatically (see below). This restricts usage and visibility of methods, [...]
Jetfire vs CSharp Differences Overview Jetfire's core syntax is identical to C#. Jetfire contains extensions to the .net C# language to simplify programming. To reduce the complexity of the programming model certain aspects of the .net C# language are not required in Jetfire. Jetfire Extensions Jetfire has a number of first class constructs not in C#. Code examples can be found at the Jetfire [...]
Overview Workflow classes can define a set of states allowing a workflow object to be in one given state. The workflow changes state by excuting 'enterstate' operator. Operations can be performed upon entering and leaving a state. Instance methods and properties can dynamically change to public or private as the state of the workflow object changes by using the 'states [...]
Overview The application interface has been designed to allow Jetfire objects to be accessed directly within .net code. Jetfire objects can be accessed a)using Jetfire framework classes b)using .net DLR interface or c) a combination of the two techniques. Jetfire programs can also access .net objects . Exceptions can be thrown in Jetfire and caught directly in .net code.
Calling Jetfire Directly using .net DLR Jetfire [...]

Jetfire Code Life Cycle
The life cycle of a Jetfire Code Class is displayed in the following picture.
The steps include:
Write the code Parse the code into an Expression Tree Run the code in the .net Framework Common Language Run-time environment Change the code in a Visual Designer In designing the Jetfire language, we started with the programmatic model. This allows us to write unit tests against the code base to ensure that the design does not stray. Once the programmatic model was mature, we introduced [...]
Jetfire Administration: Security Using Roles
Roles and Workspaces are used to secure data for the Registration solution. Securing Workflows
Let's walk through an example of how Workflows are secured. The example secures data for the XYZ Workflow. Workflow Name: 'XYZ' To secure the workflow data, follow these steps:
Create a unique Workspace for every Club. The Workspace name is 'XYZ'. Create a unique Role. The Role name is 'XYZ'. Add the 'XYZ' Role to the 'XYZ' Workspace. Create [...]
Using .Net Objects within Jetfire (V1.3.6+ ) Beginning with release V1.3.6 of the Jetfire download .net objects ( CLR objects ) can be used directly within Jetfire with a few restrictions. Dot net object support will be phased in over a number of releases beginning with V1.3.6. Static methods and properties of a .net class can be used exactly like Jetfire class within Jetfire. Instance methods and properties of a .net object can be used exactly like [...]
