About exteNd Composer Connects exteNd Composer is built upon a simple hub and spoke architecture (Fig.1-1). The hub is a robust XML transformation engine that accepts requests via XML documents, performs transformation processes on those documents and interfaces with XML-enabled applications, and returns an XML response document. The spokes, or Connects, are plug-in modules that "XML- enable" sources of data that are not XML-aware, bringing their data into the hub for processing as XML. Th

exteNd Composer Connects can be categorized by the integration strategy each one employs to XML-enable an information source. The integration strategies are a reflection of the major divisions used in modern systems designs for Internet- based computing architectures. Depending on your B2B needs and the architecture of your legacy applications, exteNd Composer can integrate your business systems at the User Interface, Program Logic, or Data levels.

What is the 5250 (TDS) Connect? The 5250 Connect XML-enables IBM AS/400-legacy system data using the User Interface integration strategy by hooking into the Terminal Data Stream (TDS). The term 5250 is commonly used to refer to the generic "dumb terminal" types used to connect to IBM AS/400 mid-range systems. When connecting to an IBM AS/400, the 5250 TDS uses IBM’s EBCDIC character-encoding scheme. The 5250 TDS, which was developed in the 1960s, emerged as that generation’s standard, and p

About exteNd Composer’s 5250 Component Much like the XML Map component, the 5250 component is designed to map, transform, and transfer data between two different XML templates (i.e., request and response XML documents). However, it is specialized to make a TN5250 connection to an AS/400 application, process the data using elements from a DOM to a terminal session, and then map the results of the terminal session to an output DOM. You can then act upon the output DOM in any way that makes se

2 Getting Started with the 5250 Component Editor Chapter 2 The Sample Transactions For demonstration purposes, three transactions are used throughout this document in the samples presented: PART, GORD, and MENU. These transactions represent typical transactions used by operators. The PART transaction represents a scenario in which an operator uses a SKU number to drive an inquiry to a database. The GORD transaction represents a scenario in which an order for an item or several items is pla

Creating a 5250 Connection Resource Once you have the XML templates in place, your next step will be to create a Connection Resource to access the AS/400 transaction. If you try to create a 5250 Component in the absence of any available Connection Resources, a dialog will appear, asking if you wish to create a Connection Resource. By answering Yes to this dialog, you will be taken to the appropriate wizard. About Connection Resources When you create a Connection Resource for the 5250 Compone
