Scan Query doesn't work with filter!

  • 1.  Scan Query doesn't work with filter!

    Posted 09-30-2020 03:54 AM
    Hi,

    I'm trying to use ScanQuery with a simple filter:


    But I got a null pointer exception.

    "Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is java.lang.NullPointerException] with root cause"

    If I remove the filter the ScanQuery works fine. Any clues? Thanks

    Best regards, João

    Hello!

    Please provide complete stack trace.

    Is it possible that cache is null or type is null?

    Hello IIya, thanks for your reply. Cache is not null neither type for sure.

    Hello!

    Which line is that (101)? Is it possible that cursor is null? Can you check?

    Thanks,

    The cursor seems not to be null, but instead it gives CacheException. Many thanks!

    Hello!

    Please try to replace the lambda with a named static inner class to see if it fixes the issue.

    Please also share the full logs from the server node(s) so that we can understand what went wrong with the lambda. Do you have peer class loading enabled?

    Regards,

    Hello!

    I already replaced the lambda with a named static inner class but it doesn't solved my problem. Same issue unfortunately.

    From the server node I only have metrics logs, nothing unusual. About the peer class loading is set to false. For this to work should I set it to true? What is the impact of this change?

    Best regards

    Hello!

    Do you have this class on server nodes? As far as my understanding goes, filter is executed on server nodes, so it needs to be either present there as a class, or be peer loaded.

    I don't have any classes on the server nodes. So, should I set peer loaded to true? Do I need extra configs in order to work?

    Thank you so much for your fast reply.

    Hello!

    Try turning peer class loading to true. If it solves your problem, now you know what to do. If not, please turn on verbose logging and share complete logs from all server nodes.

    Since peer class loading was not working properly I copied all entities and match the classpath on the server node but I still got the same error as in the beginning of this thread:

    "Null pointer exception."

    "Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is java.lang.NullPointerException] with root cause"

    Server node shows no errors even in verbose mode.

    Hello IIya,

    So I could manage things to work but not totally! As I said in the previous comment:

    1º - I copied all entities and match the class path on the server node
    2º - peer class loading to true
    3º - I'm using withkeepbinary() and working with BinaryObject...I need to deserialize() and cast to my object (as shown below in the SS and this works with lambda expression aswell)


    Results: I can make a ScanQuery at the root level of my object (ProductEntity) and I already tested it with a more complex structure (which is NOT a list). The problem is, and it was the purpose of my research, making a ScanQuery inside a List it's not working at all! Below you can see my entities.

    ROOT/MAIN ENTITY:


    ProductRefOrValueEntity



    The ScanQuery to filter for type at root level works fine but at the productRefOrValueEntity doesn't work, since it's a list inside productEntity (root).

    Below is the method I'm using and it's not working:


    Sorry for the long post and many thanks for your help IIya!

    Hello!

    Thank you for going into detail. I suspect that sometimes, getProduct() will return null. To guard against it, please make sure that productEntity.getProduct() is not null before calling getProduct().stream().

    I also don't see the point of keepBinary() if you subsequently cause deserialize(). Usually when keepBinary() is used, getField() is invoked on binaryObject, etc.

    Hello,

    If I remove withKeepBinary() it doesn't work, I got the same error as shown previously (null pointer exception).

    I just made that null check but I still got null pointer exception

    Hello!

    "class com.celfocus.jawwy.fda.product.ignite.entity.ProductEntity cannot be cast to class org.apache.ignite.binary.BinaryObject"

    This probably means that the cache is not in keepBinary state. Can you try cache.withKeepBinary().query() instead?

    Please note that productEntity.getProduct().isEmpty() will still throw a NullPointerException if getProduct returns a null list. Please replace it with a proper null check.

    Hello!

    If you don't get it working either way, keepBinary does not give you any good. You may add more and more problems on top of the existing one.

    It seems that NPE is thrown in your code. Please guard all method invocations on the line 101 to catch the one which turns out to be null. What's the line 101 now?

    So I have guarded all the method invocations on the repository side, as shown in the SS below:


    As you can see above in debug mode it doesn't stop in line 36 neither 39. For the line 46 I evaluate the expression cursor.getAll() and I got this error:


    About the line 101 that you are talking about, it's only the mapping to our DTO by mapstruct.
    Once again, thank you so much for your time Ilya!

    Finally I manage to make things work, and I made a table that I'll share with you:

    I'm just confused the way this works because, I need to have entities in the server side plus peer class loader set to TRUE.
    Thank you so much for your help Ilya!

    Hello!

    Yes, this table makes sense. The only confusing part here is why you need to use keepBinary with lists.

    Having peer class loading and models on server node seem to be requirement in your case (keepBinary or not, since you are using deserialize()).
