I'm still learing UIMA Ruta and I'm getting the error "Type "W" not defined in this script/block!" under the two "W" in a project I've found online.
WORDLIST ActionList = 'Action.txt';
DECLARE Annotation Action(STRING value);
W{INLIST(ActionList) -> CREATE(Action, "value" = W)};
What could be the problem here?
Thanks
Edit:
The stacktrace:

I am using Hibernate 6 with Amazons opensearch server in production. When i'm testing locally i don't want to use the opensearch server, instead i want to use local-filesystem to store the index files.
However i can't hibernate search to use local-filesystem even when i explicitly set it with jpaProperties.put("hibernate.search.backend.directory.type", "local-filesystem"); while at the same time not setting the property hibernate.search.backend.uris. Before all the hibernate search properties can be programmatically set i get the following error on startup:
default backend:
failures:
- HSEARCH400080: Unable to detect the Elasticsearch version running on the cluster: HSEARCH400007: Elasticsearch request failed: Connection refused: no further information

I have the following maven dependencies:

The following sets hibernate search and the lucene file destination path if using lucene only:
private Properties initializeJpaProperties() {
String luceneAbsoluteFilePath = useExternalElasticSearchServer ? null : setDefaultLuceneIndexBaseFilePath(); //Alleen relevant wanneer je geen elastic search gebruikt.
Properties jpaProperties = new Properties();

}
else{

luceneAbsoluteFilePath.append(luceneRelativeFilePath);
}
return luceneAbsoluteFilePath.toString();
}
I know that i can disable hibernate search completely with hibernate.search.enabled set to false but i don't want that. I want to be able to switch to lucene only without having to remove all the ElasticSearch/OpenSearch dependencies from my POM.xml beforehand. How do i do this?
EDIT: I just found out that you can set the backend type with hibernate.search.backend.type. This setting is set to the value elasticsearch by default. I should also be able to set this value to lucene but when i do that i get the following error:
default backend:
failures:
- HSEARCH000501: Invalid value for configuration property 'hibernate.search.backend.type': 'lucene'. HSEARCH000579: Unable to resolve bean reference to type 'org.hibernate.search.engine.backend.spi.BackendFactory' and name 'lucene'. Failed to resolve bean from Hibernate Search's internal registry with exception: HSEARCH000578: No beans defined for type 'org.hibernate.search.engine.backend.spi.BackendFactory' and name 'lucene' in Hibernate Search's internal registry.

'org.hibernate.search.engine.backend.spi.BackendFactory': HSEARCH000530: Unable to load class 'lucene': Could not load requested class : lucene
EDIT 2:
I tried the setting the following settings with no success as well.
jpaProperties.put("hibernate.search.default_backend", "lucene");
jpaProperties.put("hibernate.search.backends.lucene.type", "lucene");
jpaProperties.put("hibernate.search.backend.type", "lucene");
You need to set the backend type explicitly according to the environment:
jpaProperties.put("hibernate.search.backend.type", isProductionEnvironment() ? "elasticsearch" : "lucene");
And you also need to have the Lucene backend in your classpath:
<dependency>
<groupId>org.hibernate.search</groupId>
<artifactId>hibernate-search-backend-lucene</artifactId>
<version>${my-hibernate-search-version}</version>
</dependency>

Once I change $1 in the query to :dataId then it works.
Why is that? As per documentation, both are valid.
I am trying to setup an integration test env for debezium integration (following the instructions in this example) but the test container (default image: confluentinc/cp-kafka:5.2.1) doesn't start but throws an exception.
I am using below mentioned code to create a KafkaContainer bean
#Bean

kafkaContainer = new KafkaContainer()
.withNetwork(network())
.withExternalZookeeper("172.17.0.2:2181");
kafkaContainer.start();
}
}
return kafkaContainer;
}
it throws following exception.

I'm developing a framework that, as one of its features, enables robots to use a rule based system. We began with Jess as the RBS, and now wanted to implement drools (using Drools 5.2.0 final), which works on our development machines running on OpenJDK 6.
Our robot controller runs ARM Linux and JamVM, previously 1.4.3, but I recently compiled 1.5.4 because it was missing classes needed by drools. After failures, I installed JamVM in a virtual machine using the same configurations as when I compiled it for the controller, and there it failed with the same exceptions.
A little research showed that there are bug reports for Drools + JamVM, but this also means that it generally does work.
When Running the framework with precompiled rules with the following code...
kBase = KnowledgeBaseFactory.newKnowledgeBase();
ObjectInputStream in;
Collection<KnowledgePackage> kpkgs;
try {
in = new ObjectInputStream(Thread.currentThread().getContextClassLoader().getResourceAsStream(
packageFile));
kpkgs = (Collection<KnowledgePackage>) in.readObject();
in.close();
} catch(IOException e) {
throw new DisboticsException("Couldn't read drools knowledge package file!", e);
} catch(ClassNotFoundException e) {
throw new DisboticsException("Drools knowledge package file didn't contain expected instance.", e);
}
kBase.addKnowledgePackages(kpkgs);
kSession = kBase.newStatefulKnowledgeSession();

again, compiling the rules worked just fine in OpenJDK. We're using Janino, and it is properly referenced on the classpath (the classpath used at runtime is created by the Maven build, so contains all jars referenced by drools/janino/ anything else)
Does anyone know what's going on here and/or how to get Drools working with JamVM?
Are you compiling the knowledge packages using OpenJDK 1.6? and then trying to load it with 1.5.4? You should try compiling the original packages using 1.5.4 and see if you have the same errors.
For the stack trace, it looks like you are trying to add something to an unmodifiable list right?
Basically you are getting the exception here: kBase.addKnowledgePackages(kpkgs);
Right?
