When developing web application with Eclipse (Helios) the tomcat output is being sent to the console. Ok, but the messages are being translated to my OS language. In fact, my Eclipse is in English, but the Tomcat output (logging) is being translated to Portuguese. Probably it's a Tomcat configuration issue, but I can't find where... How do I change this behaviour? I want my entire Eclipse in English, including Tomcat.

Go to Window > Preferences > Java > Installed JREs > select preferred JRE > Edit and then add the following to Default VM arguments: <pre class="prettyprint">-Duser.language=en -Duser.country=US</pre> <img src="https://i.stack.imgur.com/rtpM0.png" alt="enter image description here">
