As long as the other application is using WFS with URN codes or WMS 1.3 the EPSG axis order is respected (and then it's up to the client to know what to do with it, which is also a common cause of failure, axis order conforming to the standard, and client not being aware of it displaying data flipped as a consequence). GeoTools, if not configured otherwise, also uses the EPSG native axis order (which can also cause its own issues, e.g., in data source declaring the CRS by integer code, but then using consistently east/north order), but can be configured to use east/north by default unless URNs are in play.
