Hi! I have the following appender: <connectionSource class="ch.qos.logback.core.db.DataSourceConnectionSource"> <dataSource class="com.mchange.v2.c3p0.ComboPooledDataSource"> <driverClass>com.mysql.jdbc.Driver</driverClass> <jdbcUrl>${connection.url}</jdbcUrl> <user>${connection.username}</user> <password>${connection.username}</password> </dataSource> </connectionSource> I also have the following: <property resource="jdbc.properties" /> The file is located under src - classpath and includes the variables However, I get error messages when I try to start tomcat unless I change the variables to static text. I also tried <property file="src/jdbc.properties /> but with no success What is wrong? -- View this message in context: http://old.nabble.com/reading-variables-from-jdbc.properties-file-tp32788737...
