A translet is a compiled java class that you can use to perform XSL transformations. By default, Integration Server uses an interpretive processor to process a style sheet. But for greater efficiency, you can instruct Integration Server to use a compiling processor provided by Xalan. The compiling processor compiles the style sheet into a translet. The style sheet compilation is performed only once per style sheet (unless the style sheet is modified) and the resultant translet is reused during subsequent transformations. As a result, transformations are performed more quickly.

Integration Server writes the translet to the same folder that contains the associated style sheet. The translet will be available even after Integration Server restarts and can be used in subsequent transformations.

To instruct Integration Server to use the compiling processor, you use the useCompilingProcessor input parameter. For more information about useCompilingProcessor, see XSLT Service Signature.
