[appengine-java] JSP compiling fails after upgrade from 1.3.8 to 1.4.0

I'm having issues using my GAE/GWT project after upgrading the GAE Java SDK from 1.3.8 to 1.4.0. It has issues compiling the JSPs, according to the error output. I've attached the stack trace. If I revert back to using 1.3.8, it compiles fine. (I'm using the Eclipse plugins.) It's entirely poss

Hi, What you are trying to achieve is based on the reflection capabilities of Java and mainly the class java.lang.Class. (See http://download.oracle.com/javase/1.5.0/docs/api/java/lang/Class.html) To describe it shortly: a) use static method forName: Class.forName(yourClassName) b) then use refl

Hi, If they don't belong to the same entity group, you will raise an exception by trying to store 2 objects in a single transaction. 2 ways to handle that: a) you make Mobile belong to same entity group as Person so you'll be able to store both in a single transaction. I understand in your qu

So using UUID's class scope static variables I can now tell which JVM services each request. What I've confirmed is that at least when using reserved instances ("Always On"), Memcache entries are only found within the same JVM instance that created the cache entry. So I only get a cache hit if the

[appengine-java] Re: Synchronized reads/writes on a memcache variable

I guess it depends on how much throughput you're expecting through the bit of the system which requires the lock - I agree that if there is huge contention then this isn't the way to go, although I'd argue that you should be changing your design anyway since synchronizing across a distributed archi

[appengine-java] Re: Synchronized reads/writes on a memcache variable

I considered the increment decrement approach, but it creates a race condition with the counter. Having many different threads/tasks trying to grab the lock at the same time could increment the number above one, even when no one has the lock because there is still a period of time between the inc

[appengine-java] Re: Synchronized reads/writes on a memcache variable

Hi, I think the following should work with the following caveats: - there's a small danger that if the server blows up before it releases the lock, that no threads would be able to update your cache, but since it's only a cache of data. This is easily mitigated by introducing a task which periodic
