MemcacheServiceFactory class not when using Memcache features on my appengine instance

[Shivkumar Krishnan]

Hi All,

 am using Memcache this way in my instance, with java.

MemcacheService syncCache = MemcacheServiceFactory.getMemcacheService();

		syncCache.setErrorHandler(ErrorHandlers.getDefault());
		myObject =  syncCache.get(key); 

On my instance logs am seeing this error:

java.lang.NoClassDefFoundError: com/google/appengine/api/memcache/MemcacheServiceFactory

should we enable anything in the appengine-web config to support Memcache on the cloud?

thx, 

 -Shiv

This seems like a question that would be better posted to Stack Overflow, rather than a discussion post. The google-appengine group is intended more for general discussion rather than 1-on-1 support assistance. Please see the main Community Support page for a list of the tags we monitor.

It sounds like you are missing the necessary App Engine JARs in your WEB-INF/lib directory in the WAR package that is being deployed. If you are using the Google Plugin for Eclipse I'd recommend creating a new Web Application project and try re-deploying, after ensuring that WEB-INF/lib contains the App Engine JARs. If you are using Apache Maven try creating a new project from the appengine-skeleton-archetype to ensure the necessary dependencies are specified in your pom.xml.
