Please help

I would like to know the service in webmethods6.5 for writeToFile service in WmSamples which is present in webMethods6.1.

It is no more part of WmSamples65…

you can get the similar from PSUtilities package…download one from the Advantage site.

PSUtilities.file:writeToFile

And copy to your custom package and make changes at your own risk…

HTH,
