I am using Java and SOAP.
I have two webservices. One (A), which generates some data, and one (B), which will update that data given specific parameters.
My question is: How can I save the data after it is generated from A for B to use?
I have read that using stateful webservices is not preferable. Instead, can I just write the XML response to a file and then get B to open and parse that file? This seems like a lot of work. What would be the ‘normal’ method to use here?
Thank you!
The usual enterprisey thing to do is to have a persistence layer (e.g. database) to save the data. You would map the XML to a relational model and store that, then regenerate the XML when B requires it.
Saving a file directly is pretty simple and might be the best solution – you’ll need to manage locking etc. yourself. Or you could do a very simple DB with the XML in a column.
