Log4J Logging

This adapter outputs data from the process via Log4J to the server log. All data that can be converted into a string can serve as input data. In AdvancedMode, data can be output directly at various log levels in an XML document with an adapter-specific structure.

This adapter transmits its input data unchanged to the next process step.

Properties

Operation

Determines which operation the adapter executes

Possible values: Execute: Execute adapter

Parameters

Adapter	Main class of the adapter (do not change!) Possible values: `de.softproject.integration.adapter.log4j.Log4jAdapter`: Main class (default)
logger	Used logger to which the log message is to be sent Possible values: Any logger name `X4Logger`: Output as X`X4Logger` in the server console via Log4j
level	Level of the output log message. In the Log4j configuration a threshold (parameter `Threshold`) is defined, from which level log messages are output; mostly this is `INFO`. Possible values: `DEBUG`: Output debug information (if allowed by the logging configuration) `INFO`: Output general information or processed process data `WARN`: Output a warning for an unexpected situation `ERROR`: Output error message (caught exception) `FATAL`: Output critical system error Log messages with the level `FATAL` are output with the level `ERROR` for technical reasons. The output receives `FATAL:` as prefix.
advancedMode	Activate extended mode in which an input XML document with an adapter-specific structure is processed separately. Such an XML document can contain log messages that are output at a specified log level (see example below) Possible values: `yes`: parse input XML documents `no`: Do not parse input XML documents (default)
modifyMessage	Modify/expand log message Possible values: `Nothing`: Output log message with unchanged layout `AddPid`: Additionally output the current process instance ID in the log message (default).

Status values

`1`	The operation was executed successfully.
`-1`	The operation failed due to a technical error.

Example

If the advancedMode parameter is enabled: This adapter-specific input XML document contains information about the log level and the log messages to be output. The messages are output directly to the server log:

      <message level="INFO">This is a info message. </message>
      <message level="WARN">This is a warn message. </message>
      <message level="ERROR">This is an error message. </message>
      <message level="FATAL">This is a fatal message. </message>
   </log>
