Configuring Java Development Kit log files

You can configure the batch processor to use Java Development Kit (JDK) log files, and also configure the level of detail recorded in the logs.

About this task

JDK log files have the following predefined logging levels:

ALL – log all messages.
FINEST
FINER
FINE
CONFIG – log all configuration level messages and above.
INFO – log all informational level messages and above.
WARNING – log all warning level messages and above.
SEVERE – log only severe error messages.
OFF – disable logging.

To configure JDK log files:

Procedure

To set the logging type to JDK:
1. Edit the DWLLog.properties file.
2. Change the value of the LoggerFactory property to com.dwl.base.logging.DWLLog4jLoggerFactory:
```
LoggerFactory=com.dwl.base.logging.DWLJDKLoggerFactory
```
Note: By default, Apache log4j is defined as the logging type.
To configure the detail level of the messages that are displayed on the console during batch processing:
1. Edit the JDKLog.properties file.
2. Depending on the logging level you wish to set, change the value of the java.util.logging.FileHandler.level property to one of the predefined logging levels.
```
handlers=java.util.logging.FileHandler, ,java.util.logging.ConsoleHandler
java.util.logging.FileHandler.level=SEVERE
```
  Tip: If you wish to turn off console output so that the user can have a clear console, remove the console handler from the handlers property:
```
handlers=java.util.logging.FileHandler
java.util.logging.FileHandler.level=SEVERE
```
To configure the detail level of the messages that are logged in the batch processing log files:
1. Edit the JDKLog.properties file.
2. Depending on the logging level you wish to set for each log file type, change the value of the following logging level properties to one of the predefined logging levels:
  - Activity log:
```
BulkProcessing.Activity.level=INFO
```
