kandi X-RAY | objectify Summary
Objectify is a Java data access API specifically designed for the Google Cloud Datastore (aka the Google App Engine Datastore). It occupies a "middle ground"; easier to use and more transparent than JDO or JPA, but significantly more convenient than the low-level API libraries that Google provides. Objectify is designed to make novices immediately productive yet also expose the full power of the Datastore. Important note about versions: Objectify v5 and prior use the Google App Engine API for Java and therefore can only be used within Google App Engine Standard. Objectify v6+ uses the Cloud Datastore API and can be used from anywhere - GAE Standard, GAE Flex, GCE, or outside Google Cloud entirely. See the FAQ for more information.

QUESTION
I have a collection of very simple Java objects which I store in Google Firestore database (native mode) using Objectify 6.0.7. Storing, deleting, and querying objects all work fine, but a query with an orderBy clause on a single field fails with "no matching index found". The exact same code works perfectly in a Datastore project (so the Java code is not in question).
I could not find clear documentation as to whether Objectify can work with Firestore and I suspect this is the issue. Thoughts?
This is the query:
...ANSWER
Answered 2022-Jan-05 at 04:27Objectify v6 uses the com.google.cloud:google-cloud-datastore library as a low-level API. I'm pretty sure that library only works in Datastore Mode. Google has a completely different (and much more primitive) Java library for Firestore Mode.
So I think for now you need to use Datastore Mode and not Firestore Mode.

QUESTION
I locally run my app which uses Datastore. The app is written in Java and uses Objectify. The code is like the below.
...ANSWER
Answered 2021-Jun-24 at 12:07Well, the answer to your question is: It should support it, as the emulator is suppose to support everything that the production environment does. That being said I did went through the documentation after seeing your question and found that here it's stated that:
The Cloud SDK includes a local emulator of the production Datastore mode environment.
But if you were to follow the link, there are hints that this is an emulator to both the legacy Datastore and Firestore in Datastore mode. So this might be why you are seeing this behavior. With that information at hand, it might be a good idea to open a case in Google's Issue Tracker so that they're engineering team can clarify if this is an expected behavior or not and if not, fix this issue.

...ANSWER
Answered 2021-Apr-14 at 17:58Based on your most recent edit, I think you'll find the problem is that your for
loop isn't matching any nodes. Your document doesn't contain any elements named component
or structuredBody
. The xmlns="urn:hl7-org:v3"
declaration on the root element mean that all elements in the document exist by default in that particular namespace, so you need to use that namespace when matching elements:
