If a webMethods product is equipped with webMethods language packs and some of those language packs correspond to the language used by the operating environment in which the product is running, the product writes its log entries in the language used by the operating system. If the product is equipped with no language packs or with language packs that do not correspond to the language used by the operating system, the product writes its log entries in U.S. English.

Suppose your operating environment uses Japanese as its language. You have installed language packs including the Japanese Language Packs on Integration Server, so Integration Server stores its own log entries in Japanese. You have not installed the Japanese Language packs on Trading Networks, so Integration Server stores Trading Networks' log entries in U.S. English.
