[eclipselink-users] Eclipse Link error with LockType
|
Hi All,
1- I'm getting the following error after upgrading to eclipselink
1.1.0 M 5 while using OSGI & Spring.
A lock type can only be used with a select query (which allows the
database to be locked where necessary).
Another piece of info which may or may not be related:
2- I extended org.eclipse.persistence.jpa.osgi.PersistenceProvider in
order to be able to externalize configuration for datasource, dialect,
etc... into spring. [I have a defect open for that] I'm not certain
if that may be the culprit, but I am guessing not since it's failing
while trying to build JPA queries. So I have attached that.
Basically a rip off off the same PersistenceProvider code , aside from
setting the classloader.
3- The M5 bundle plugin file with all dependencies should probably
come bundled with the 2.0 persistence preview. [I was getting OSGI
failures due to javax.persistence.Cache]
Other than that, any thoughts on the the stack trace
org.springframework.beans.factory.BeanCreationException: Error
