Currently, we do not have built-in webMethods IS services to manage transactions on Ehcache puts and gets. When needed, one may have to either implement whole solution as Java services using ehcache Java api or come up with generic way of using them. I took the opportunity to develop this package which has got transaction management services for caching reads/ writes. I tried to keep the service names and signatures almost same as our "pub.art.transaction.* " services. So it should be easy to use them straight forward.
Below links help you to understand this package in a better way and also gives details on how to configure and use this package
