Adding new step to Kettle 2.5.2

[virafbankwalla]

Hi, I am using Kettle 2.5.2 for data conversion. As part of a transformation, I need to call application level utilities. I have been doing this through a javascript step that in turns calls java.

It has been reported that the insertion of this step significantly reduces performance. I am considering on writing a Java Step that wraps the function.

1. Could someone please point me to documentation and /. or an example by which I can build a java step and make it available to kettle.
   1. This step should have design time support. For example, I am considering using the calculator step and plugging in my business functions. This includes the UI and transformation definition.
   2. This step would need the runtime support

Thanks

Following may be of help: http://wiki.pentaho.org/display/EAI/...ration+Plug-In

And a list of extra plugins available (most with source code) to have a look at:

Note that when you write your own plugin you will have to convert the code between PDI v2 and v3 as well.
