ObjectCacheOSCacheImpl issue.
I'm trying to use OSCache with OJB as I need disk persistence.
My setup is working great with the other cache implementations.
I got ObjectCacheOSCacheImpl.java from the db-obj-1.0.1-contrib
package, set up oscache-2.1, and set ObjectCacheClass to
ObjectCacheOSCacheImpl in my config.
When I run it I get the following error, where OJB appears to be
trying to pass a Properties object to ObjectCacheOSCacheImpl's
constuctor:
java.lang.NoSuchMethodException:
ObjectCacheOSCacheImpl.<init>(org.apache.ojb.broker.PersistenceBroker,
java.util.Properties)
I see that the constructors that ObjectCacheOSCacheImpl does have are
all empty, so just for fun I added an empty constructor with the
profile that OJB was looking for. The Properties object that is passed
is null, by the way.
Once I added this constructor, OJB ran and was fetching data from the
database. I could also see log output from OSCache itself like
"Creating cache". Also it created a disk cache directory on the
system, but doesn't write any files there.
OJB does not seem to be calling cache() or lookup() on
ObjectCacheOSCacheImpl ( I put some logging in it to see if it was).
Here are my ojb properties in case there is anything relevant there:

are you sure that "OSCache" is really used by OJB? You set the OSCache
in OJB.properties, but is a cache in repository_database.xml file
(object-cache element in in the jdbc-connection-descriptor) set too? Are
specific caches set for classes (object-cache element in class-descriptor)?

Re: ObjectCacheOSCacheImpl issue.
Posted by Michael Newton <mi...@gmail.com>.
I wrote a test as you suggested and it actually passed for both
ObjectCacheOSCacheImpl and for the ObjectCacheDefaultImpl
I have print statements in the constructor, lookup, and cache methods
in ObjectCacheOSCacheImpl.
Here is my test:
public void testCache () throws Exception {
PersistenceBroker broker =
PersistenceBrokerFactory.defaultPersistenceBroker();
Attribute a = new Attribute();
Identity oid = broker.serviceIdentity().buildIdentity(a);
broker.serviceObjectCache().cache(oid, a);
Attribute b = (Attribute) broker.serviceObjectCache().lookup(oid);
assertNotNull(b);
}
and here is the output (running with ObjectCacheOSCacheImpl )
[junit] Testsuite: legion.service.CacheTest
[junit] Tests run: 1, Failures: 0, Errors: 0, Time elapsed: 1.472 sec
[junit] ------------- Standard Output ---------------
[junit] OSCache constructor
[junit] ------------- ---------------- ------------
No "OSCache lookup" or "OSCache cache" messages are printed, and
OSCache does not write it's disk cache (although it creates the
directory)
So what's going on here?

all ObjectCache implementations need a specific constructor expect an PB

hmm, if OJB never calls cache or lookup in ObjectCacheOSCacheImpl it
will never call these methods on all ObjectCache implementations,
because they are all handled in the same way.
Did you write a test case to check the cache? Something like
Article a = new Article();
Identity oid = broker.serviceIdentity().buildIdentity(a);
broker.serviceObjectCache().cache(oid, a);
Article b = broker.serviceObjectCache().lookup(oid);
assertNotNull(b);
This test should pass with ObjectCacheDefaultImpl and your
ObjectCacheOSCacheImpl too.
