我想将liferay ce连接到postgres，所以我将portal-ext.properties添加到以下路径
${CATALINA_HOME}/webapps/ROOT/WEB-INF/classes
有了这个背景
jdbc.default.driverClassName=org.postgresql.Driver
jdbc.default.url=jdbc:postgresql://127.0.0.1:5432/postgres
jdbc.default.username=postgres
jdbc.default.password=postgres
我应该提到我将postgres.jar放在${CATALINA_HOME}/lib/ext中
但是当我运行tomcat时，我面临以下错误：
