Swagger-Springfox + WebFlux + JavaX validation (JSR 303) support - swagger

I am trying to implement Swagger for documentation, so that it picks both JSR 303 validation annotations and Spring Webflux based classes.
In Spring Boot project, I am currently using:
Spring Webflux framework for some classes
JSR 303 annotations on domain classes for Bean Validations and Constraints
Swagger integration with Spring Fox framework for generating OpenAPI documentation.
In build.gradle, following dependencies are used and I am able to make Spring Webflux + SpringFox work but only JSR 303 is giving issues:
springBootVersion = '2.0.2.RELEASE'
//JavaX-validation
'javax.validation:validation-api:2.0.0.Final',
'javax.el:javax.el-api:3.0.0',
'org.glassfish.web:javax.el:2.2.6'
//SpringFox-Swagger
'io.springfox:springfox-swagger2:2.9.2',
'io.springfox:springfox-spring-webflux:3.0.0-SNAPSHOT',
'io.github.swagger2markup:swagger2markup-gradle-plugin:1.3.3'
Here is the issue :
When below dependency is added to achieve "Spring Webflux + SpringFox + JSR 303",
**'io.springfox:springfox-bean-validators:2.9.2'**
I am getting the following error,
[WARN ] 2018-11-01 10:16:50.535 [main] SpringApplication - Unable to close ApplicationContext

Several blogs say that,SpringBoot version 2x doesn't support JSR 303. I am not sure but I tried to see it doesn't work.
Please advise.
Also, If JSR 303 is not supported currently, what other Validation annotations can be used apart from JSR 303 ?
I don't want to use Swagger core annotations, only because it is messing up code readability.

Add in your pom.xml:
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>3.0.0</version>
<scope>compile</compile>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>3.0.0</version>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-spring-webflux</artifactId>
<version>3.0.0</version>
</dependency>
And use the annotation:
#EnableSwagger2
In you swagger configuration.

Officially springfox doesn't support spring webflux(more informations you can read here: springfox issues).
But you can try SNAPSHOT version like this: webflux-swagger.
As I can see version greater than 2.3.2, support for bean validation annotations:pringfox-support-for-jsr-303.

Any idea what could be the problem ? Does Thinkerpop3 work with neo4j 2.2.5?
Looks like that there are problems with dependency versions in your setup.
If you look at neo4j-tinkerpop-api-impl - you can see that there is currently release for Neo4j 2.2.5 in master. But maven central has 2.2 version.
Ensure that you are using correct version of Neo4j dependencies everywhere.
In maven dependency tree can be helpful.

How to get WrappingNeoServerBootstrapper working in Jython 2.7b3

I have an embedded neo4j database (2.1.3) that I am using with Jython 2.7b3. I would like to be able to use the web admin provided by WrappingNeoServerBootstrapper.
My current code is:
from org.neo4j.server import WrappingNeoServerBootstrapper
from org.neo4j.server.configuration import ServerConfigurator
from org.neo4j.graphdb.factory import GraphDatabaseFactory
graphDb = GraphDatabaseFactory().newEmbeddedDatabase('data/')
config = ServerConfigurator(graphDb)
WrappingNeoServerBootstrapper(graphDb, config).start()
However when I try to start WrappingNeoServerBootstrapper I get a very long stack trace which ends on:

Thankful for any ideas on what I missing?
WrappingNeoServerBootstrapper is deprecated, according to this link. You won't find a word about NeoServerBootstrapper in recent manuals...
the solution should be writing extensions or plugins for neoserver.
You'll need to include these dependencies if you haven't already -
<dependency>
<groupId>org.neo4j.app</groupId>
<artifactId>neo4j-server</artifactId>
<version>${neo4j.version}</version>
</dependency>

Maven 3 ejb-client dependency visible at compile time not visible at runtime for ejb 3.1 app client

I have a simple EJB 3.1 project which uses Glassfish 3.1.2 as AS and Maven 3 for dependency management. In the pom.xml of ejb project I set the generateClient option to true. I successfully deployed my ear to the server and then I tried to create a simple standalone client. Here is the pom.xml of the client:
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>duan</groupId>
<artifactId>ejb31-app-client</artifactId>
<version>1.0-SNAPSHOT</version>
<name>ejb31-app-client</name>
<description>my app client</description>
<dependencies>
<dependency>
<groupId>org.glassfish.main.appclient.client</groupId>
<artifactId>gf-client-module</artifactId>
<version>3.1.2</version>
<type>pom</type>
<scope>compile</scope>
<exclusions>
<exclusion>
<artifactId>tools</artifactId>
<groupId>com.sun</groupId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>duan</groupId>
<artifactId>ejb31</artifactId>
<version>1.0-SNAPSHOT</version>
<type>ejb-client</type>
</dependency>
</dependencies>
where ejb31 is my ejb project for which I client is generated.
The Java class used in my application client is:
public class Test {
private static HelloWorldBeanRemote helloWorldBean;
public static void main(String[] args) {
String jndiPath = "java:global/ejb31-ear-1.0/ejb31-ejb/HelloWorldBean";
try {
Context ctx = new InitialContext();
System.out.println("Looking up bean at: " + jndiPath);
helloWorldBean = (HelloWorldBeanRemote) ctx.lookup(jndiPath);
System.out.println("Found helloWorldBean:" + helloWorldBean);
System.out.println("Calling sayHello():");
String greeting = helloWorldBean.sayHello();
System.out.println("HelloWorldBean said:" + greeting);
} catch (NamingException e) {
System.err.println("Could not find HelloWorldBeanRemote!");
System.err.println("JNDI path used for lookup:" + jndiPath);
e.printStackTrace();
}
}
}
The application client is compiled without problem by Maven. If I run this from Eclipse I get this exception:
Caused by: java.lang.ClassNotFoundException: ro.duan.ejb.HelloWorldBeanRemote
at java.net.URLClassLoader$1.run(Unknown Source)
at java.security.AccessController.doPrivileged(Native Method)

at com.sun.ejb.EJBUtils.lookupRemote30BusinessObject(EJBUtils.java:414)
... 7 more
But then if I manually add ejb-client.jar to the build path it works like a charm. So my conclusion is that somehow ejb-client.jar is available at compile time, but not at runtime. Any thoughts on how to solve this?
Remove the following line:
<scope>compile</scope>

Why JBoss's jsf implementation doesnt have javax.faces.model.DataModel?

Someone, please, knows why this occours and how to solve it?
Thanks
The solution for the java.lang.NoClassDefFoundError: javax/faces/model/DataModel exception in JBoss AS 7.1.1.Final is exactly what #BalusC said before:
Look like a bug in JBoss classloading:
community.jboss.org/thread/177061 If you provide JSF API/impl in
EAR/lib (which is actually the wrong place), then it's solved. –
BalusC Jan 24 at 12:09
If you are using maven, just put
<dependency>
<groupId>javax.faces</groupId>
<artifactId>jsf-impl</artifactId>
<scope>compile</scope>
</dependency>
....
<defaultLibBundleDir>lib</defaultLibBundleDir>
An another solution (It is not a good practice) is replace the jar in jboss-as-7.1.1.Final\modules\com\sun\jsf-impl\main to another implementation of jsf specification.
