I am reading a database table and must decrypt a field in the record and then update the table. I have a DBInput, Reformat, and DBOutput but not sure how to execute the decryption function contained in a locally provided jar file.

Can this be done within the Reformat component?

Thanks for the help… I am new to CloverETL.

Yes, just set the _transformClass_ attribute. The jar file containing the function must be set in the class-path. See also example SimpleExamples/graph/graphOrdersReformat.grf, that can be downloaded from [http://sourceforge.net/projects/clovere … p/download](http://sourceforge.net/projects/cloveretl/files/cloveretl.engine/rel-3-0-1/cloverETL.examples.rel-3-0-1.zip/download)
