Question

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：
