I am using Datastage 6.0.1

From Datastage I want to call a java function and pass two parameters.
The java function will return two values to datastage job towhich I ve write back to a text file.
How I ll do this?

Hi,
in case you can't use the external routine facility, which as I understand, is your case.
you can use a commnad line to run your java, returning the result via the return code or store it in a file and then read it.

if possible, you might concider implementing the function's logic in DS Basic.

any other solutions would make you specify on your configuration and what you want to acieve more clearly.

IHTH

Yes, if you must use Java, why can't it write the two values to a file? This is a much easier interface to manage - returning more than one value is always tricky! But if you can program it in Java chances are it can be programmed as easily in DataStage BASIC, as Roy points out, then you don't have to worry about deployment issues with your Java code - everything is contained within the DataStage environment.

Under the DSEngine directory on unix you should find a directory called unishared.load/uojsdk/lib and this should be included in your classpath for java. There are sample programs and some documentation in the subdirectories of unishared.load. There are java equivalent methods for most of the Basic functions and they are documented in ther UniObjects for Java Developers Guide part number 70-9041-951.

Dilip,
First check the Ascential e.services site if there's a port for your Unix.
Then order it from your local rep. (But I'm not getting any incentive
