Hi, I have some problem in reading the properties file from servlet.I'm using apache tomcat server. Following is the code snippet.I tried putting the properties file in all possible places(classes, webApps, in the context path) but the application failed to load it.It is giving nullpointer exception at prop.load(is); public class LoadProps { public Properties getProps() { String propertyfile = "myProps.properties"; Properties props = new Properties(); try { is = this.getClass().getResourceAsStream(propertyfile); props.load(is); }catch (Exception ioe) { ioe.printStackTrace(); } return props; } } Appreciate your help

Take a look to ServletContext.getResourceAsStream. If your properties file is located in tomcat-dir/webapps/myapp/WEB-INF/file.properties you could use getServletContext().getResourceAsStream("/WEB-INF/file.properties").

"VSSM Kumar", you have previously been warned on one or more occasions regarding adjusting your display name to meet JavaRanch standards. This is not optional. Please take a look at the JavaRanch Naming Policy and adjust your display name to match it prior to your next post. Your display name must be a first and a last name separated by a space character, and must not be obviously fictitious. Be aware that accounts with invalid display names are disabled. bear JavaRanch Sheriff

I found some strange things.The servlet class file (not source file) is there in my workspace (c:\workspace\<myappName>\build\classes)and nowhere else.my tomcat server is totally in differnt path.The serlvet mapping in web.xml has the url pattern "/<somepath>".How come at runtime my application could find the servlet class without copying the servlet class file on to the server (i mean deployment)? I'm using Eclipse as IDE.Does Elipse do it automatically? If so, where does it place the class file? I searched my entire C: drive for the class file but could not find it.
