Building Custom CFXAPI Tags
Sometimes, the best approach is to develop elements of your application by building
executables to run with ColdFusion. Perhaps the application requirements go
beyond what is currently feasible in CFML. Perhaps you can improve application
performance for certain types of processing.
To meet these types of requirements, you can use the ColdFusion Extension
Application Programming Interface (CFXAPI) to access ColdFusion functions.
This chapter documents custom tag development using Java or C++, however, it is
also possible to develop tags in Borland’s Delphi.
