我尝试将我的rest应用程序连接到DB2数据库。我使用Tomcat 9来测试我的应用程序 重要：我在虚拟机中工作。 我使用jndi配置设置了context.xml：
context.xml中
<Resource name="jdbc/reeval" type="javax.sql.DataSource"
auth="Container" username="XXX" password="XXX"
driverClassName="com.ibm.db2.jcc.DB2Driver"
url="jdbc:db2://host.sample.fr:4461/DB2PROA" />
当我的应用程序尝试执行SQL请求时，出现此错误消息：
16:26:49,502 DEBUG SqlExceptionHelper:124 - Unable to acquire JDBC Connection [n/a]
