【问题描述】：
我正在尝试以下查询：
@PersistenceContext(unitName="miscPU")
private EntityManager em;
public ClientCompanyDAO() {
}
public List <ClientCompany> findAllClientCompanies() {
Query query = em.createQuery("select c from ClientCompany c");
return query.getResultList();
}
运行时出现错误：SQLException: No database selected from the getResultList method.
实体的设置如下：
@Entity
@Table(name="clientcompany")
public class ClientCompany extends Company implements Serializable {
这是我的 persistence.xml 文件：
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="2.0">
<persistence-unit name="miscPU">
<jta-data-source>java:/jdbc/misc</jta-data-source>
<properties>
<property name="hibernate.show_sql" value="false"/>
<property name="hibernate.transaction.flush_before_completion" value="true"/>
</properties>
</persistence-unit>
<persistence-unit name="autojobsPU">
<jta-data-source>java:/jdbc/autojobs</jta-data-source>
<properties>
<property name="hibernate.show_sql" value="true"/>
<property name="hibernate.transaction.flush_before_completion" value="true"/>
</properties>
</persistence-unit>
</persistence>
已创建 java:/jdbc/misc 数据源并在 Wildfly 19 上成功 ping。数据源上的 url 为 jdbc:mysql://localhost:3306/misc。
我可能会错过什么？
更新：根据要求，这里是堆栈跟踪。由于行数的堆栈溢出限制，IJ 不得不删除其中的一些。大概是因为它多次尝试完成查询，所以它重复了几次。

嗨，你能用完整的堆栈跟踪更新问题吗？它可能会为问题提供提示！
-
根据要求，我将完整的堆栈跟踪附加到原始帖子的末尾。
-
可悲的是，我无法从中做出任何贡献。我的建议是尝试使用简单的
main客户端连接到该数据库。从运行 WildFly 的同一台机器/VM/容器中执行此操作！使用完全相同的数据库 URL 和凭据。怎么了？还有一件事：仔细检查捆绑在应用程序中的 JAR 文件，确保没有系统提供的库（例如 Hibernate）潜入。
