derby.stream.error.field

Function

Specifies a static field that references a stream to which the error log is written. The field is specified using the fully qualified name of the class, then a dot (.) and then the field name. The field must be public and static. Its type can be either java.io.OutputStream or java.io.Writer.

The field is accessed once at Derby boot time, and the value is used until Derby is rebooted. If the field is null, the error stream defaults to the system error stream (java.lang.System.err).

If the field does not exist or is inaccessible, the error stream defaults to the system error stream. Derby will not call the close() method of the object obtained from the field.

Default

None.

Example

derby.stream.error.field=java.lang.System.err

Scope

system-wide

Dynamic or static

This property is static; if you change it while Derby is running, the change does not take effect until you reboot.
