(Eclipse Persistence Services - 2.5.2.v2): org.eclipse.persistence.exceptions.DatabaseException Exception Description:

I'm facing this error whit my EAR projec: This ear have 4 modules (EJB-standard-2 web modules)
I'm not using MAVEN. Server is Wildfly17.0.1 final
I'v already put connector in every web-inf\lib folder
also put connector in wildfly17.0.1.Final\modules\system\layers\base\com\mysql\main and created the module.xml
<resources>
<resource-root path="mysql-connector-java-8.0.12" />
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
I also tried to deploy connector within wildfly console but nothing worked so far.
I also tried with com.mysql.jdbc.Driver in my persistence.xml
<?xml version="1.0" encoding="UTF-8"?>

<property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver"/>
<property name="javax.persistence.schema-generation.database.action" value="create"/>
</properties>
</persistence-unit>

dunno what to do, everytime it seems a pretty simple solution to put connector jar into projects folder but it dosen't work

JPA - Sql Server error: Cannot open database "Taijitan" requested by the login

I'm making a Java program that connects to an SQL Server database together with a small team. Their code runs succesfully, but whenever I try to launch the Java application, I get the error: Cannot open database "Taijitan" requested by the login. The login failed. ClientConnectionId:f96fe50c-768a-4e85-8673-3e39a8feb1e4
I already checked my TCP/IP in SQL Server Management / Configuration.
In the netbeans.conf file I changed the JDKhome to jdk10.0.2.
In the env var I added the path to jdk10.0.2.
I also added the sqljdbc_auth.dll file to programfiles/java/jdk10.0.2/lib and also to bin. In SQL Server Manager I also checked if my Windows account has all the required permissions.

SonarQube Ant task, failed to download the file

I am running a simple Ant script for SonarQube and have the following error:
FileNotFoundException: C:\Users\c5187668\sap\simpleAnt.sonar\batch\sonar-batch-maven-compat-5.1.2.jar|99845a2f47eaef85b29978725f82c50c"
SonarQube Server Version 5.1.2
Apache Ant(TM) version 1.9.6 compiled on June 29 2015
Sonar Ant Task version: 2.0
Java 1.6 - so, we cannot use modern version of Sonar Ant.
Can it be fixed somehow? Any ideas?
The Ant script:

P.S. by question marks ????? I hide real server name and credentials.

Your Ant Task version (2.0) is not compatible with your SonarQube version. This compatibility matrix shows that v2.2 is a minimum requirement since SonarQube 3.7 (2.4 being the best choice for SonarQube 4.5+).
You should upgrade your SonarQube Scanner for Ant and also use a supported version of Java.

You told Ant that your SonarQube server is running at http://?????? , the script therefore fails (quite understandably) to download the resources it needs from the server.
Fix this:
<property name="sonar.host.url" value="http://??????" />
The value should be the URL you use to browse your SonarQube server's homepage.
P.S.: you'll also have to fix sonar.jdbc.username and sonar.jdbc.password

The problem was I used Persistence.createEntityManagerFactory("unit") to create EntityManagerFactory and injected it in other Spring beans.
Now I put
<bean id="emf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceUnitName" value="unit" />
</bean>
directly in applicationContext.xml.
Still doesn't explain what was wrong with previous approach, but it works.

JPA switching from "drop-and-create-table" to "none" results in massive Bugs

My team and me are currently working at a project using Hibernate-Validation and JPA.
Problem: we decided to use "drop-and-create-table" during the development-phase. everything worked just fine and as everything was implemented we changed the generation-mode to "none" (with a stable database running).
What it was doing before: We drop the table, create the table from our entities with specific attributes and fill the table with some datasets.
What it is doing now: We work on the existing, previously working, table (already filled with some data); but now some relations seem to be missing.
Now we have encountered a number of Exceptions during runtime and we can't locate them. It seems, that some attribute-relationships were deleted or something, because there are Exceptions (e.g. NullPointerExceptions) thrown, that were not thrown before.
Is there anything else we have to change in the persistence.xml, except the generation-mode?
here's the code for the persistance.xml:

My guess is that your database is missing some data.
When you run your populate in memory, you are populating the shared cache and the database. However you are most likely no building your objects correctly.
Maybe you have transient fields that you set in memory, but when you read from the database, these transient fields are null.
Maybe you have bi-directional relationships and are not setting both sides of the relationships, so are not populating the database correctly.
Maybe you have not mapped some attributes correctly, so the data in the database is not correct.
My guess is that if you disabled the shared cache, you would have the same errors.
