I've already posted about a problem which brought me to this error, but I write it something more specific about the error:
When I use spellcheck.q in my query to define what will be "spellchecked", I always have this error, for every configuration I try:
java.lang.NullPointerException

All my other functions works great, this is the only thing which doesn't work at all, just when I add "&spellcheck.q=my%20sentence" in the query...
Has anyone already have solved this problem?
It is fixed in trunk.
So get latest code from SVN or a nightly build.

I have Kotlin code:
cluster.removeIf { t: SolutionElement -> t.timeStart < minimumDate } //Clusters.kt:66
Where cluster object is kotlin Mutable list. When I try to run this code on Google App Engine standard environment I got an error:

In build.gradle for this module, I had:
compileKotlin{
kotlinOptions{
jvmTarget = 1.6
}
}
Without that parameter error was:
Uncaught exception from servlet
java.lang.NoClassDefFoundError: net/toolla/teamly/services/matcher/Clusters$removeExpired$1
Where "removeExpired" is name of the function which contains the above line.
I changed the code above to some less convenient and older syntax, but it would be great to know how to use some more up to date techniques.
The class java.util.function.Predicate was introduced in Java 8. So run it with 8. About th
...
* #since 1.8

#FunctionalInterface
public interface Predicate<T> {
About that error:
java.lang.NoClassDefFoundError:
net/toolla/teamly/services/matcher/Clusters$removeExpired$1
Ensure that you have that class on your classpath
Instead of removeIf, which is a method from JDK 8 and is therefore not supported on JDK 6, you can use the removeAll method from the Kotlin standard library, which is supported on all JDK versions.

Support for getting credentials compatible with Dataflow via Application Default Credentials in AppEngine exists in version 1.9.20+ of the Google API libraries. Please make sure that your WAR that you deploy to AppEngine contains google-api-client version 1.9.20+ and google-api-client-appengine version 1.9.20+. Beware that you may need to upgrade other dependencies because of this change.

Please Help me out. Thanks in advance - Shri Kant
Please upgrade to the latest version of the Java SDK (1.8.0 as of May 18th, 2013): https://developers.google.com/appengine/downloads#Google_App_Engine_SDK_for_Java
Current versions of the SDK no longer contain the stack trace you list in the bug:
at com.google.appengine.api.files.dev.LocalFileService.throwError(LocalFileService.java:196)
I had to go to the source code for com.google.appengine.api.files.GSFileOptions (gae java sdk 1.8.1.1) to be able to find out what a valid bucket name should be.
Line 37: this.fileName = FileServiceImpl.GS_FILESYSTEM_PREFIX + bucket + "/" + key;
The Javadoc does not provide any information on the format of the bucket. In this case do not include the /gs/ prefix or / at the end in your bucket name (like I was doing.) If you have used other APIs (like the BlobStor API) this can be confusing since they require the /gs/ prefix.
I was getting the same exception and stack trace with 1.8.1.1 so a bad bucket name can be the cause.
Also, you may want to try the Google Cloud Storage Client Library.
I am new to GAE development.
for me insertion using jpa to the datastore is working fine, but retrieval is not happening.
Below is a method which authenticates the user when he try to login.
public boolean loginUser(User user) {
EntityManagerFactory emf = Persistence
.createEntityManagerFactory("SOAApp");
EntityManager mgr = emf.createEntityManager();
boolean login=false;
Query query=mgr.createQuery("select u from User u where u.userName=:uid and u.password=:pwd");
query.setParameter("uid", user.getUserName());
query.setParameter("pwd",user.getPassword());
query.setMaxResults(1);
try {
user=(User) query.getSingleResult();
System.out.println("user : "+user.getName());
if(user!=null) {
System.out.println("logged in...");
login=true;
}
}
catch(Exception e) {
e.printStackTrace();
}
finally {
mgr.close();
}
return login;
}
but I am getting the following errors when trying to execute the method by passing a user object with valid username and password.
java.lang.NullPointerException

Please help me
Still searching?
I had the same problem and my entity User had a primaryKey named userId that was of type 'int'. Now I changed it to 'Long' and all of my problems and warnings are all gone! Maybe this helps you out!
I look forward hearing from you!
Regards,
Stephan
The reason why u get nullpointerexception is that getSingleResult method returns null. Because u used (User)query.getSingleResult(), the typecasting of null value throws exception.
I think there is no related user in datastore, so you are getting exception.
<?xml version="1.0" encoding="UTF-8"?>
<datastore-indexes autoGenerate="true">
<datastore-index kind="HABERLER" ancestor="false" source="manual">
<property name="__key__" direction="desc"/>
</datastore-index>
HABERLER is table name. Write your table name instead of HABERLER. Then create a datastore-indexes.xml file in WEB-INF directory. Then copy above code into this file.
Make sure you that the keys for your entities are of valid types as detailed here:
https://developers.google.com/appengine/docs/java/datastore/jdo/creatinggettinganddeletingdata#Keys
The exception you are getting is most likely related to a key issue.
We are using pull queues with backends in our scenario and our backend tries to lease tasks from our pull queue after some fixed intervals and in case there are no tasks , it does not do anything and in case there are any , those are processed . Yesterday we got this TransientFailureException in our system , which exactly is happening while my servlet is trying to lease task from pull queue . And the exception kept coming until we stopped our backend .
Our code snippet --
{
Boolean leasedTaskFromFastQueue = true;
Queue fastQueue = QueueFactory.getQueue("FastQueue");
Queue slowQueue = QueueFactory.getQueue("SlowQueue");
List<TaskHandle> tasks = fastQueue.leaseTasks(
3600, TimeUnit.SECONDS, 1);
TaskHandle taskHandle = null;
if(tasks.size() > 0) {
taskHandle = tasks.get(0);
}
}
We aret getting error on the line where we lease task from fastQueue , which is a pull queue
<queue>
<name>FastQueue</name>
<mode>pull</mode>
</queue>
I am also pasting my error trace , in case that helps

It happend to us also, TransientFailureException is an internal error that as far as we could see had nothing to do with our code. We ended up by automatically restarting the backend if 50 errors happened in a row.
