I am unable to test the EmbeddedSOlrServer and I run into following exception
Exception in thread main
java.lang.NoClassDEfFOundError:org/apache/lucene/codecs/PostingFormat
at
org.apache.solr.core.SolrResourceLoader.reloadLuceneSPI(SolrResourceLoader.java:179)
Code -
System.setProperty("solr.solr.home", "c:/apps/solr4/example/solr");
CoreContainer.Initializer initializer = new CoreContainer.Initializer();
CoreContainer coreContainer = initializer.initialize();
EmbeddedSolrServer server = new EmbeddedSolrServer(coreContainer, "");
I believe I have all jars in class path and solr.solr.home setting is also updated. Please advise
i solved the problem adding the lucene-core dependency into the test scope:
<dependency>
<groupId>org.apache.lucene</groupId>
<artifactId>lucene-core</artifactId>
<version>4.3.0</version>
<scope>test</scope>
</dependency>

I am learning to hibernate so I made a small app for crud operation using mySQL as database. However, I am getting some errors and I cannot find the solution anywhere. SDK 17.0.2, I am not using maven , Also all hibernate final jar files have been added
my class:
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import com.luv2code.hibernate.demo.entity.Student;
public class CreateStudentDemo {
public static void main(String[] args) {
// Create session factory
SessionFactory factory= new Configuration()
.configure("hibernate.cfg.xml")
.addAnnotatedClass(Student.class)
.buildSessionFactory();
//Create session
Session session = factory.getCurrentSession();
try {
//Create a Student object
System.out.println("Creating new student");
Student tempStudent = new Student("Pau;", "Wall", "paul#luv2code.com");
//Start a transaction
session.beginTransaction();
//save the student object
session.save(tempStudent);
//commit transaction
session.getTransaction().commit();
}
finally {
factory.close();
}
}
}

java removed java.xml.bind from JAVA 9 and higher editions.
You need to add these jar files manually to your library
basically you can to that in this way.
If you use Intellij this is the easyest way:
jaxb-impl-2.3.0.jar
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-impl</artifactId>
<version>2.3.0</version>
</dependency>
jaxb-core-2.3.0.jar
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-core</artifactId>
<version>2.3.0</version>
</dependency>
jaxb-api-2.3.1.jar
<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.3.1</version>
</dependency>
javax.activation-api-1.2.0.jar
<dependency>
<groupId>com.sun.activation</groupId>
<artifactId>javax.activation</artifactId>
<version>1.2.0</version>
</dependency>
If you use intellij here is a step my step to get these files through IDE
go to project structure:
Libraries, and click + sign
Chick to from Maven:
Paste these dependencies to the search.
It will automatically find exact jar files to download, Kist Paste it and click to the enter that is it.
Also later you can just add these files to the classpath just in case:
java removed java.xml.bind from JAVA 9 and higher editions.
Here is the eclipse solution:
In Eclipse IDE:
Download these jar files and paste them inside lib folder:
Go the project properties: The last line
Done these steps:
Happy Coding! :)
I am using OpenJDK 11 and here's my code for Getting SOAP message.
SOAPMessage message = MessageFactory.newInstance(dataDTO.getSoapVersion()).createMessage(null, new ByteArrayInputStream(encryptedResponse.getBytes()));
Sometimes it throws error:
javax.xml.soap.SOAPException: Unable to create SAAJ meta-factoryProvider com.sun.xml.internal.messaging.saaj.soap.SAAJMetaFactoryImpl not found
at javax.xml.soap.SAAJMetaFactory.getInstance(SAAJMetaFactory.java:94) ~[saaj-api-1.3.5.jar:?]
I think it is because it looking for the method under saaj-api 1.3.5 instead of saaj-impl 1.5.1
below is my POM dependency:
<dependency>
<groupId>javax.xml.soap</groupId>
<artifactId>javax.xml.soap-api</artifactId>
<version>1.4.0</version>
</dependency>
<dependency>
<groupId>com.sun.xml.messaging.saaj</groupId>
<artifactId>saaj-impl</artifactId>
<version>1.5.1</version>
</dependency>
<dependency>
<groupId>javax.xml.soap</groupId>
<artifactId>saaj-api</artifactId>
<version>1.3.5</version>
</dependency>
Since javax.xml.soap-api 1.4.0 is using by some critical function, the risk is too high for removing it. Anyway can make sure my function work as expected with loading proper class ?
I have created a business process and build it as a jar in Kie Workbench (version 7.16.0.Final).
When trying to execute the process I got the Runtime exception.

I faced this same issue (although in KIE/Drools 7.17.0.Final) and the problem was a missing dependency. In my case I had Drools/KIE/JBPM as a JBoss module and didn't have all required JARs declared in module.xml.
What I did to fix it was to add the following two JARs to module.xml (and of course, put the JARs into the module's main folder):
jbpm-bpmn2-7.17.0.Final.jar
jbpm-flow-builder-7.17.0.Final.jar
You can find these JARs under Drools and jBPM tools distribution.
When using as runtime version one of the latest:
<runtime.version>7.42.0.Final</runtime.version>
Then, it's enough to have the following set of libraries (which are automatically added if you create a Drools project with Eclipse+Drools plugin):
<dependency>
<groupId>org.kie</groupId>
<artifactId>kie-api</artifactId>
</dependency>
<dependency>
<groupId>org.drools</groupId>
<artifactId>drools-core</artifactId>
</dependency>
<dependency>
<groupId>org.drools</groupId>
<artifactId>drools-decisiontables</artifactId>
</dependency>
<dependency>
<groupId>org.jbpm</groupId>
<artifactId>jbpm-test</artifactId>
</dependency>
There's a sample demo project here: Using Drools Rules with jBPM
I'm writing Spring Data Neo4J repository tests with #DataNeo4jTest and all is well until I write a test against a custom query that uses a procedure, for example apoc.coll.intersection. The error declares procedure apoc.coll.intersection is unknown. I have the APOC JAR on the classpath so am guessing I need to find a way to register the procedure with the embedded datasource/driver that #DataNeo4jTest uses.
Any help would be appreciated. Thanks.
Some background to understand the situation: The #DataNeo4jTest annotation provides you the Spring Boot based auto configuration. It will pick up your Neo4j connection configuration in your application.properties (either test or production if no test properties are defined) and create Neo4j-OGM's SessionFactory with the matching configuration for you.
There are two ways to solve you problem:
Define the SessionFactory bean by yourself with embedded instance setup and configuration:
#Bean
public SessionFactory sessionFactory() {
GraphDatabaseService graphDatabaseService = new GraphDatabaseFactory()
.newEmbeddedDatabaseBuilder(Paths.get("pathToDb").toFile()).newGraphDatabase();
registerProcedure(graphDatabaseService, MyProcedure.class);
EmbeddedDriver driver = new EmbeddedDriver(graphDatabaseService);
SessionFactory sessionFactory = new SessionFactory(driver, "package");
}
Or during "runtime" with the already existing SessionFactory bean e.g. in your test setup (make sure to do this just once)
EmbeddedDriver loadedDriver = (EmbeddedDriver) sessionFactory.getDriver();
registerProcedure(loadedDriver.getGraphDatabaseService(), MyProcedure.class);
both will call a method like this
public static void registerProcedure(GraphDatabaseService db, Class<?>...procedures) throws KernelException {
Procedures proceduresService = ((GraphDatabaseAPI) db).getDependencyResolver().resolveDependency(Procedures.class);
for (Class<?> procedure : procedures) {
proceduresService.registerProcedure(procedure,true);
proceduresService.registerFunction(procedure, true);
proceduresService.registerAggregationFunction(procedure, true);
}
}
Update: Added example and version definitions.
GraphDatabaseService graphDatabaseService = new GraphDatabaseFactory()
.newEmbeddedDatabaseBuilder(Paths.get("path/to/db").toFile()).newGraphDatabase();
// Option I
registerProcedure(graphDatabaseService, MyProcedure.class);
EmbeddedDriver driver = new EmbeddedDriver(graphDatabaseService);
SessionFactory sessionFactory = new SessionFactory(driver, "org.neo4j.ogmindex.domain");
// Option II if embedded driver is not directly accessible anymore
EmbeddedDriver loadedDriver = (EmbeddedDriver) sessionFactory.getDriver();
// register the apoc version function
registerProcedure(loadedDriver.getGraphDatabaseService(), Version.class);
// Test call to apoc.version
Session session = sessionFactory.openSession();
session.query("RETURN apoc.version()", emptyMap())
.forEach(System.out::println); // outputs {apoc.version()=3.4.0.2}
pom.xml definition for the example above:
<dependency>
<groupId>org.neo4j.test</groupId>
<artifactId>neo4j-harness-enterprise</artifactId>
<version>3.4.6</version>
</dependency>
<dependency>
<groupId>org.neo4j.procedure</groupId>
<artifactId>apoc</artifactId>
<version>3.4.0.2</version>
</dependency>
After messing around with this for quite some time, trying different dependency versions and also playing with configuration code as suggested by #meistermeier I found a solution, which was to simply use the correct version of the 2 Neo4J test JARs I was referencing. This is a Spring Boot project so here are all the Neo4J dependencies in my Maven POM that solve the issue:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-neo4j</artifactId>
</dependency>
<dependency>
<groupId>org.neo4j.test</groupId>
<artifactId>neo4j-harness</artifactId>
<version>${neo4j.ogm.version}</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.neo4j</groupId>
<artifactId>neo4j-ogm-embedded-driver</artifactId>
<version>${neo4j.ogm.version}</version>
<scope>test</scope>
</dependency>
I set neo4j.ogm.version to match the version specified in the spring-data-neo4j-parent POM (which is brought in transitively).
Created the maven scala project.
I had correctly specified all the configuration . But still facing this error.
any help appreciated.
I solved this error.
Its coming because I had make the entry for org.scalatest plugin and there is no src/test/scala dir and no test cases.After removing org.scalatest plugin entry from pom file everything work fine.
For anyone that comes across this issue in the future, make sure you have the following dependency in your pom.xml.
<dependency>
<groupId>org.scalatest</groupId>
<artifactId>scalatest_2.11</artifactId>
<version>3.0.0</version>
<scope>test</scope>
</dependency>
