If you are using a MyEclipse WebProject, the WEB-INF/classes directory is a output folder. Output folders in eclipse can be “srubbed” by eclipse automatic buider at any time. So you can’t put files that they you might not want deleted. However, you can put that properties file in a “src” folder. Any non-java class in a source folder will just be copied straight over to the output folder. So if you put your properties file in the root directory of a “src” folder, it will be copied into the root directory of the the WEB-INF/classes directory.
