Here is a question I have not been able to get answered...

I'm trying to use OSCache's API to cache to disk. I've tried the
following

Properties props =3D new Properties();
props.put("cache.memory","false");
props.put("cache.persistence.class","com.opensymphony.oscache.plugins.di
skpersistence.DiskPersistenceListener");
props.put("cache.path","c:\\inleasingApp\\cache");
props.put("cache.capacity","10000");
props.put("cache.unlimited.disk","true");
admin =3D new GeneralCacheAdministrator(props);

In this case, I got a 1.cache file in the correct location.

I then did this

  try
  {

   if (!StringUtils.isEmpty(reportData.getWhichValue()))
   {
     // Get from the cache
       results =3D (InleasingReportsData)
admin.getFromCache(reportData.getWhichValue());
   }
   else
   {
    results =3D new InleasingReportsData();
    results.setFirstName("No First Name");
    results.setLastName("No Last Name");
    results.setWhichValue("No value");
   }
  }
  catch (NeedsRefreshException nre)
  {
   try
   {
    // Store in the cache
    admin.putInCache(reportData.getWhichValue(), reportData);
    results =3D new InleasingReportsData();
    results.setFirstName("No First Name");
    results.setLastName("No Last Name");
    results.setWhichValue("No value");
   }
   catch (Exception ex)
   {
    // We have the current content if we want fail-over.
    results =3D (InleasingReportsData) nre.getCacheContent();
    // It is essential that cancelUpdate is called if the
    // cached content is not rebuilt
    admin.cancelUpdate(reportData.getWhichValue());
   }
  }

pulled pretty much from the website.

I get the following output

[DEBUG] 10 Aug 2004 15:23:00,298  AbstractConcurrentReadCache:get(671)
- get called (key=3D1)
[DEBUG] 10 Aug 2004 15:23:00,298

[DEBUG] 10 Aug 2004 15:23:00,330
AbstractConcurrentReadCache:persistStore(1061)  - persistStore called
(key=3D1)

But when I try to retrieve using get from cache, it is never there.

I've replaced the GeneralCacheAdministrator and its properties with just
a call to new Cache(false,true) to not use memory,but use unlimited
disk.

Same results.

Any ideas what I'm doing wrong?

Thanks,

Glad to hear people are still thinking about OSCache.  I wonder about
the comment made about the "weak configuration".  I am actively
contributing to it right now and would love any input on it.

As far as a pluggable cache system goes, I think hibernate's model works
fairly well and I would like to see something like that in Spring.

One selfish question, I researched all the other open source caches out
there; however, I found them all to be immature except OSCache.  Is
there a reason you are considering EHCache instead?  I have asked this
question in many forums but can never get any answer.
