The command-chain configration file, command-chain.xml, is located in /WEB-INF/resources in the web application file.

This mapping decupples the development of JSP's from the configuration of command-chains. It allows GUI-developers to use an abstract name for a requested action, which the administrator/deployer mapp to a command-chain. Changing the execution of an action is as simple as definig a new command-chain and chainging the mapping.

SCAM has identified a set of frequently used commands. If not any of theese commands suit your needs, you are free to add your own commands.

A simple method to share objects is through the se.kmr.scam.client.http.util.Context object.

Context provides access to request attributes in different scopes:

In a multipart/form-data request is the request body streamed, which is not handled by the normal HTTP-request parser. Thus is field values not available as request parameters in a multipart request.

To transparently provide field values to the middleware are theese values instead made available as request attributes.

For multipart requests is se.kmr.scam.scam.http.filter.MultipartEncodeFilter responsible for making field values available as attributes. Make sure this filter is included in web.xml.
