[appengine-java] Query with several filters on same list property potential exploding index problem...
I handle a class MyClass that holds a list property myListProperty. I use the low-level API to query over this class, with a dynamic number of filters over this very single field. Those filters mainly use different kind of operators (inequality filters and in filters). Sample code: Query q = new Query(MyClass); q.addFilter(myListProperty, FilterOperator.IN, oneCollection); q.addFilter(myListProperty, FilterOperator.IN, anotherCollection); q.addFilter(myListProperty, FilterOperator.GREATER_THAN, oneString); q.addFilter(myListProperty, FilterOperator.LESS_THAN, anotherString); When executing this query in dev mode, it generates the following index in datastore-indexes-auto.xml: !-- Used 15 times in query history -- datastore-index kind=MyClass ancestor=false source=auto property name=myListProperty direction=asc/ property name=myListProperty direction=asc/ property name=myListProperty direction=asc/ /datastore-index You got it : this would generate a mega-exploding index problem when in productionŠ Can someone confirm that this kind of index is NOT REQUIRED when executing that query on the actual datastore ? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] Could not initialize class PMF
Are you trying to reference PMF in your client side GWT code? This won't
work. It has to be in your server side code. This is what the stack trace
seems to indicate.
If not, I'd say look to make sure PMF is in your classpath.

Re: [appengine-java] Could not initialize class PMF
Hi Laci,
NoClassDefFoundError can mean one of two things:
1) You really didn't include the class in your webapp, so it can't be found.
You should check the classes in WEB-INF/classes and the jars in WEB-INF/lib
to make sure com.reference.server.PMF is present.
2) Your PMF class threw an exception in its static initializer the very
first time the JVM tried to class load it. If this is the case, there should
be an ExceptionInInitializerError somewhere in your logs. In this specific
case, something could have failed in your initialization of pmfInstance.
