Implementing Multiple operations in a web service in JCAPS 5.1.3

Question

Hi,
I am using JCAPS 5.1.3 and have a requirement where in I have to implement multiple operations and expose them as a webservice.
The complexity of operations is medium, they have to log the input message into database.
In order to achieve this I have come up with two models:
Model-1:1.Create a Business process in eInsight and use event based decisons and implement various operations.
2.Create jcd operations in order to log messages into database.
3.Expose the business process as a webservice
Model-2:1.Create a jcd for each operation and make it Callable as an External SOAP web service.
2.Expose each jcd as a webservice
I would like to know which of these models gives better performance for the webservice .I see eInsight in earlier versions was low in performance.
Please let me know if you have any ideas on this.
Thanks in advance.
Regards,
Nag

I'd try the idea #1 first. EInsight performances could be an issue only for very CPU-intensive operations, but as you need to interact with a database usually this I/O is going to be the real bottleneck. Instead, you should avoid eInsight not mainly because of hypothetical performance issues but when you foresee the need to write very complex logic, which is much easier to code and maintain in Java within JCDs than in BPEL. However remember that JCDs exposed as WS need the latest ESR Rollup to work properly, if I well recall they were single-threaded in plain JCAPS 5.1.3.
By the way, if your WSDL describes multiple operations you could probably implement them one by one by distinct eInsight BPs if you need to distribute them differently, you are not forced to use a single BP with event-based decisions, it is a matter of your taste and requirements. In my experience however in the past I had some annoying issues with WSDL exposing multiple operations and eInsight, hopefully those are gone with the latest Rollup but do some quick test yourself before betting all your money on it.
