java.util.logging

We are currently using Tomcat 7 with a single log configuration specified using -Djava.util.logging.config.file and the default ClassLoaderLogManager with -Djava.util.logging.manager="org.apache.juli.ClassLoaderLogManager". This works great for a one-time startup config. We have several servlets and other code that runs outside the servlet context. We run on a dedicated tomcat server that we completely control, and we want all the code to use the same log configuration. We are using the java.util.logging API for logging. This means that LogManager.getLogManager().getLogger(name) needs to work,

I have a fresh installaion of tomcat. To improove the logging I edit the conf/logging.properties . Step 1 I change the Line java.util.logging.ConsoleHandler.level = FINE to java.util.logging.ConsoleHandler.level = FINER Step 2 And append the line org.apache.catalina.level = FINER Step 3 Then I start the server and if I fail to authenticate to http://localhost:8080/manager/ with username MyUsername and MyPassword I see this output: FINE [http-bio-443-exec-2] org.apache.catalina.authenticator.AuthenticatorBase.invoke Security checking request GET /manager/html FINE [http-bio-443-exec-2] org

I want to extend the java.util.logging.Logger class. I have the following code. I am "forcing an error" in our app and the class I created is not being called. Here is the error I am generating on purpose but it doesn't go in the code I wrote: //Generate error to test the logger String[] myStringArray = new String[3]; String test; test = myStringArray[5]; I also tried this but it still doesn't go in my code even if I have the same function definition: logger.log(Level.FINE, "test my logger"); Here is my logger extension. Is it possible for this to get triggered when an unhandled exception is

I'm working on a JSF-Project with Primefaces on Websphere Application Server. Since Primefaces uses java.util.logging, I'm using the jul-to-slf4j Bridge to capture the Primefacs Logs into my Log4J Logfile. But using the jul-to-slf4j Bridge, all java.util.logging Messages will be in my Logfile, including general Websphere Messages like "Application started" or "Server started". Can the jul-to-slf4j be configured, so it only redirects specific Messages (e.g. everything from org.primefaces ) to SLF4j and leave the rest as it is? I found a solution using java.util.logging.Filter , the filter just

I have java.util.logging to print output to a file. It works fine. However, the messages contain chinese characters which correspond to the log level and the time the messages are logged. How can I make it print english instead of chinese characters ? This is what the current messages look like 11月 08, 2016 8:28:03 下午 mySamples.testing.TestingFile errorFunction 資訊: Exception: 123 Start your application by passing the language on the command-line to override the current default language of the OS. java -Duser.language=en MyApplication 来源： https://stackoverflow.com/questions/40486841/java-how-to

I am familiar with the java.util.logging (JUL) framework, I use it extensively. Recently, I started using a library that does its logging through log4j. When I start my application I now get the following printed on the console: log4j:WARN No appenders could be found for logger (com.example.thirdparty.Library). log4j:WARN Please initialize the log4j system properly. It appears that log4j has a solution for this: JULAppender which will send everything logged with log4j to the logging framework that I use. I can't find any examples that show me how to configure log4j to use this appender. The

I have an WebSphere Application Server which runs an WebApp. I start the Server from Eclipse. The main logging framework in that application is log4j2, but there are some third party libraries which use java.util.logging. I want to redirect those logs to log4j2 so it uses my filters, log format etc. To achieve this I can use the Log4j JDK Logging Adapter . Usually one would set the system property -Djava.util.logging.manager=org.apache.logging.log4j.jul.LogManager , for example in the jvm.options. The problem is that I can't seem to make that solution work because the server uses java util
