I have a hashmap returned from a java service and put on the pipeline. I am having some difficulty in obtaining a collection of the Values only from the hashmap using the webmethods flow language. How do you go about doing this ?
have a look at the PSUtilities package. There is alot of usefull services, especially PSUtilities.hastable, which allows you to perform standard map operations put/get/contains within flow services.
Next solution is to write your own java services for given opeartion.
If you wrote the java service, why return a HashMap in the first place? Have your java service build an IData and put that on the pipeline.
