I did my due diligence by doing Google search but did not find any answer.
We have a REST service bases Web Application, for which backend is implemented using Groovy and Grails (1.3.7 with Groovy 1.7.x). I understand how Open Session In View works in general for Hibernate, and when configuring Hibernate with Spring, we could specify for which set of URLs, OSIV should work in the filter configuration.
The issue is I cannot find how to exclude a set of URLs from the scope of OSIV filter (like matching *.js, *.gif, etc). I found from the Hibernate log, that even for Javascript file request, Open Session In View kicks in and opens a session and closes it.
