Eclipse Persistence Services-2.5.2.v2：org.eclipse.persistence.exceptions.DatabaseException异常描述：

如何解决Eclipse Persistence Services-2.5.2.v2：org.eclipse.persistence.exceptions.DatabaseException异常描述：

我的EAR项目遇到了这个错误：该耳朵有4个模块（EJB-standard-2 Web模块）

我没有使用MAVEN。服务器是Wildfly17.0.1最终版本

我已经将连接器放在每个web-inf \ lib文件夹中

还将连接器放在wildfly17.0.1.Final \ modules \ system \ layers \ base \ com \ MysqL \ main中并创建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>

我也尝试在wildfly控制台中部署连接器，但到目前为止没有任何作用。

我也在persistence.xml中尝试使用com.MysqL.jdbc.Driver

<?xml version="1.0" encoding="UTF-8"?>

<persistence version="2.1" xmlns="http://java.sun.com/xml/ns/persistence"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
   xsi:schemaLocation="http://java.sun.com/xml/ns/persistence 
   http://java.sun.com/xml/ns/persistence/persistence_2_1.xsd">
   
   <persistence-unit name="jpaserver" transaction-type="RESOURCE_LOCAL">
//varIoUs classes
      <properties>
         <property name="javax.persistence.jdbc.url" value="jdbc:MysqL://localhost:3306/progettoestateserver"/><!-- da cambiare -->
         <property name="javax.persistence.jdbc.user" value="root"/>
         <property name="javax.persistence.jdbc.password" value=""/>
      <property name="javax.persistence.jdbc.driver" value="com.MysqL.jdbc.Driver"/>
       <property name="javax.persistence.schema-generation.database.action" value="create"/>
      </properties>
   </persistence-unit>
</persistence>

不知道该怎么办，每次将连接器jar放入项目文件夹中似乎都是一个非常简单的解决方案，但是它不起作用
