[appengine-java] Re: After upgrade to GAE SDK 1.5.0 - Cache is not working
I am having the same issue this:
CacheFactory factory =
net.sf.jsr107cache.CacheManager.getInstance().getCacheFactory();
Throws a CacheException with no stack trace and the message:
net.sf.jsr107cache.CacheException: Could not find class:
'com.google.appengine.api.memcache.jsr107cache.GCacheFactory'

[appengine-java] Re: After upgrade to GAE SDK 1.5.0 - Cache is not working
I have found a workaround until a new zip will be released.
I have taken the
appengine-jsr107cache-1.4.3.jar from a former SDK installation
renamed it to appengine-jsr107cache-1.5.0.jar and placed it under
C:\Google-Apps\SDK\1.5.0\lib\user
I have checked it on local & production environment and it works like
a charm

[appengine-java] Re: After upgrade to GAE SDK 1.5.0 - Cache is not working
I've been programming to the jcache interface that's included in the
appengine sdk
javax.cache.Cache and that still works in SDK 1.5.0.
appengine's service locator (MemcacheService) finds the implementation
for the interface.
import javax.cache.Cache;
import javax.cache.CacheException;
import javax.cache.CacheFactory;
import javax.cache.CacheManager;
CacheFactory cacheFactory =
CacheManager.getInstance().getCacheFactory();
cache = cacheFactory.createCache(Collections.emptyMap());

[appengine-java] Re: After upgrade to GAE SDK 1.5.0 - Cache is not working
1.5.0.1 was published and fixes this issue. I had to manually download it and override the 1.5.0 package, as the Eclipse 3.6 plugin update does not see this 1.5.0.1 package online yet. Link to download this update: http://code.google.com/p/googleappengine/downloads/detail?name=appengine-java-sdk-1.5.0.1.zip&can=2&q= Hope this helps. Jerome PS: The manual copy of appengine-jsr107cache.jar was working just as well, and was less troubles to deal with though.

Re: [appengine-java] Re: After upgrade to GAE SDK 1.5.0 - Cache is not working
Sorry about this, folks. We'll get a new SDK built that includes the right
appengine-jsr107cache.jar file. In the mean time you can use javax.cache or
a previous version of appengine-jsr107cache.jar (there were no changes to it
in 1.5.0), but I would strongly encourage everyone to move from javax.cache
to net.sf.jsr107cache once this problem is fixed. We are no longer making
bugfixes to javax.cache and will at some point remove it from the SDK.
