Periodically getting EPStatementException on Northwind examp
Re: Periodically getting EPStatementException on Northwind e
There is a known issue with Northwind - others have reported the same
viewtopic.php?f=35&t=3519&p=5660&hilit=sleep#p5660
Basically the work around is to place a sleep in the initialize method of the app.
Northwind was developed as a example on how to inject custom esper along with rifidi services mapped to a business use case
The recommended production pattern is to encapsulate any custom esper into as a rifidi service
http://wiki.rifidi.net/index.php?title= ... _Jumpstart
This is how the example app to be included in the 3.0 developers guide
3.0 is targeted to be released to public week of April 7th
In the meantime refer to the db app as this wiil be the example app starting in 3.0
http://wiki.rifidi.net/index.php?title= ... _Jumpstart
Note: To our knowledge teh above issue has only been reported inside Eclipse and not once exported to a run-time Rifidi server instance but either way having Esper statement in a service as opposed to injected in code is teh recommended pattern
Here is link on how to export app from Ecslipse to a run time Rifidi server instance
