Directory structure for Java SOAP server project

I would like to create simple Java SOAP web service that should run on Tomcat 10. I'm using Eclipse and Maven for this purpose. I'm using artifact maven-archetype-webapp for this purpose. After project was created I just removed webapp folder and have created java one instead of it. I suppose there I can put my Java code for web services? But how to tell Eclipse to treat this folder as Java source location? I can managed it like system folders, but not Java packages. What other directory structure changes I should do in order to create Java SOAP server?

Way before i think main loaded but all the other classes failed:

I'd appreciate any help. I have been trying to run my app for a while now and nothing seems to be working.
Thanks in advance.

java.lang.NoClassDefFoundError: org/hamcrest/Matchers

I have running JUnit5 testcases w/ Maven 3.
Now I want to use library hamcrest in Java import in Testcase AppTest.java:
import static org.junit.jupiter.api.Assertions.*;
import static org.hamcrest.Matchers.greaterThan;
import static org.hamcrest.Matchers.lessThan;
For Testcase AppTest.java that uses App.java:
double result;
result = app.probability_a_dash(23);
System.out.println("result: "+ result);
assertEquals(lessThan(0.5d), result);
The error on the import is:
java.lang.NoClassDefFoundError: org/hamcrest/Matchers
How do I get hamcrest library properly integrated in maven build:
mvn on the command line integrates hamcrest properly, only IDE intelliJ IDEA is mixing up the imports!
Unfortunately JUnit5 does not detect that 0.0 < 0.5 with hamcrest lessThan: How do I get a passing testcase on this?

I had the same error running my maven project. So, I had to use hancrest-all, a self-contained hamcrest jar containing all of the sub-modules in a single artifact.
<dependency>
<groupId>org.hamcrest</groupId>
<artifactId>hamcrest-all</artifactId>
<version>1.3</version>
<scope>test</scope>
</dependency>
Check this link: https://mvnrepository.com/artifact/org.hamcrest/hamcrest-all/1.3

Instead of JUnit5 assertEquals, I had to use in AppTest.java the following hamcrest methods:
import static org.hamcrest.Matchers.*;
import static org.hamcrest.MatcherAssert.assertThat;
and
assertThat(result, lessThan(0.5d));

How can I exclude folders from the WAR?

I tried to follow Maven packagingExcludes jars regex and this is how my pom.xml file looks. The full path to the node_modules is project-directory/src/main/webapp/node_modules

I added the following to exclude the nodes_modules folder but I still see that my build includes it and generating it, takes several minutes (Total time: 03:16 min)
<packagingExcludes>
%regex[node_modules]
</packagingExcludes>
How do I exclude the node_modules from my war file?

you're using regex version of packagingExcludes which is not the use case of yours. Try to specify folder path specified here as follows
<packagingExcludes>WEB-INF/node_modules/**</packagingExcludes> <!--or correct path to your folder-->

The method neo4jServer in the file DatabaseConfiguration.java of type DatabaseConfiguration must override or implement a supertype."

I want to develop a java application on top of a Neo4j graph database.
For this application I want to reuse the boiler plate code from Mr. Vlastaridis on Github via https://github.com/jhipster/jhipster-neo4j-app/tree/2a6fa89f8c8aa13dc7ea7856b4ee521efceeb7c7
This Neo4j example is developed for the old 2.xx version of Neo4j. I want to update the database to version 3.xx. Therefore I have to update the Spring Data Neo4j project implementation in this application.
I have therefore modified the necessary entries in the POM.XML file. I used the properties and dependencies of https://github.com/neo4j-examples/movies-java-spring-data-neo4j-4 as an example for the modifications in my POM.XML file.
To my knowledge this top POM.XML implementation should result using Spring Boot into an inclusion of all other dependancies including the necessary Spring Data Neo4j dependencies. This seems not to be the case however.
As a result of the modified POM.XML I end up with an error in Eclipse and Maven: "The method neo4jServer in the file DatabaseConfiguration.java of type DatabaseConfiguration must override or implement a supertype."
Question: how do I modify the POM.XML in the boiler plate code in order to remove the error message?
The implementation of DatabaseConfiguration.java looks like this:
package com.mycompany.myapp.config;
import org.neo4j.ogm.session.Session;
import org.neo4j.ogm.session.SessionFactory;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Profile;
import org.springframework.data.neo4j.config.Neo4jConfiguration;
import org.springframework.data.neo4j.repository.config.EnableNeo4jRepositories;
import org.springframework.data.neo4j.server.Neo4jServer;
import org.springframework.data.neo4j.server.RemoteServer;
import org.springframework.data.repository.query.QueryLookupStrategy;
#Configuration
#Profile("!test")
#EnableNeo4jRepositories(basePackages = "com.mycompany.myapp.repository", queryLookupStrategy = QueryLookupStrategy.Key.CREATE_IF_NOT_FOUND)
public class DatabaseConfiguration extends Neo4jConfiguration {
private final Logger log = LoggerFactory.getLogger(DatabaseConfiguration.class);
#Override
#Bean
public Neo4jServer neo4jServer() {
log.info("Initialising server connection");
return new RemoteServer("http://localhost:7474", "neo4j", "1234");
}
#Override
#Bean
public SessionFactory getSessionFactory() {
log.info("Initialising Session Factory");
return new SessionFactory("com.mycompany.myapp.domain");
}
#Override
#Bean
public Session getSession() throws Exception {
log.info("Initialising session-scoped Session Bean");
return super.getSession();
}
}
My POM.XML file looked like this. Due to the limitations of Stackoverflow I removed most of the non-Neo4j related properties and dependencies in this POM.XML.
<?xml version="1.0" encoding="UTF-8"?>

You are using spring-data-neo4j in version 4.1.1.RELEASE. In your DatabaseConfiguration class you are extending Neo4jConfiguration. Your problem is, like the error says, you want to override a method which is not existing in the superclass. In version 4.1.1.RELEASE of SDN there is no method called neo4jServer what you can override (This method was removed something about 4.1.0.RELEASE)
So what you can do is to change your configuration suitable on the SDN version you are using - remove the neo4jServer method and use a configuration like this:
#Bean
public SessionFactory getSessionFactory() {
return new SessionFactory(getConfiguration(), "com.mycompany.myapp");
}
#Bean
public Neo4jOperations neo4jTemplate() throws Exception {
return new Neo4jTemplate(getSession());
}
#Bean
public org.neo4j.ogm.config.Configuration getConfiguration() {
org.neo4j.ogm.config.Configuration config = new org.neo4j.ogm.config.Configuration();
config.driverConfiguration().setDriverClassName("org.neo4j.ogm.drivers.http.driver.HttpDriver")
.setURI("http://localhost:7474")
.setCredentials("neo4j", "1234");
return config;
}
#Bean
#Scope(value = "request", proxyMode = ScopedProxyMode.TARGET_CLASS)
public Session getSession() throws Exception {
return super.getSession();
}
Another option (what i would not recommend) is to change the version of SDN in your pom.xml to
<spring-data-neo4j.version>4.0.0.RELEASE</spring-data-neo4j.version>
