I am trying to configure a JDBC logger via code (no problems using it from XML file).
I'm using Log4j2 version 2.11.2. What examples I can find are vague, incomplete, or not related. I'm finding code that may be for log4j1 and log4-jdbc but no jars in mvnrepository.com so is that old and deprecated now too? I have: log4j-1.2-api-2.11.2.jar log4j-api-2.11.2.jar log4j-core-2.11.2.jar log4j-over-slf4j-1.7.2.jar log4j-slf4j-impl-2.11.2.jar log4j-web-2.11.2.jar slf4j-api-1.7.26.jar in a war project. In a nut shell, the following code ColumnConfig[] columnConfigsArray = columnConfigs.toArray(new ColumnConfig[columnConfigs.size()]); JNDIConnectionSource connectionSource = new JNDIConnectionSource(); connectionSource.setJndiLocation(activityLogConfiguration.getDataSourceUrl()); AppenderComponentBuilder appenderBuilder = configBuilder.newAppender(ACTIVITY_LOG_APPENDER, "JDBC") .addAttribute("connectionSource", connectionSource) .addAttribute("columnConfigs", columnConfigsArray) .addAttribute("tableName", activityLogConfiguration.getSchemaNameAndTableName()) .addAttribute("bufferSize", activityLogConfiguration.getBufferSize()); // complete the configuration appenderBuilder.build(); // build the logger and add to the appender AppenderRefComponentBuilder appenderRef = configBuilder.newAppenderRef(ACTIVITY_LOG_APPENDER); LoggerComponentBuilder logger = configBuilder.newLogger(ACTIVITY_LOG_APPENDER, Level.INFO); logger.add(appenderRef); logger.build(); configBuilder.add(logger); always results in: 09:55:16,864 INFO [stdout] (ServerService Thread Pool -- 77) 2019-03-18 09:55:16,863 ServerService Thread Pool -- 77 ERROR No ConnectionSource provided:
