The NetBeans generate code like Logger.getLogger(svr.class.getName()).log(Level.SEVERE, null, ex); to output exception in catch.It will display in console.
After I deploy my project,I cannot see any exception info.How to output those error messages to file and in console when console is available?
Thanks folks.
The logging system in NetBeans is based on the standard JDK's java.util.logging and complies to it as much as possible. In order to output error messages to a file, you can provide your own logging properties file on the classpath of your project.
