I am using SLF4J + Logback to output messages to the eclipse IDE console.
Logger LOG = LoggerFactory.getLogger(MyClass.class);
LOG.debug("test");
But sometimes the whole console output gets cleared and i cannot see older messages. Is that enough information so that you can help me out?
It sounds like you might be hitting the default console output limit in Eclipse. You can edit it under Window > Preferences > Run/Debug > Console. Either increase the console buffer size (default is 80000 characters) or uncheck the "limit console output" box.

I'm using Tomcat9 as a server and I'm using Catalina.out as my logger output "System.out" and "System.error" . I don't know every time I open and refresh the Catalina.out file, it gives out the weird output (as shown in picture below) and this output is keep increasing until more than million length. It makes slow loading to open the Catalina.out file. After this weird thing loaded, the logger output that I needed will be at the bottom of those things.
Opened Catalina.out via notepad++ will have below output :
I expect the output doesn't give this weird annoying output.
Guess you need some formatting here. Just follow these steps.
Open your file in Notepad++
Type Control-A (select all)
Type Control-H (replace) In 'Find What' type '\x00'
In 'Replace With' leave BLANK In 'Search Mode' Selected 'Extended'
Then Click on 'Replace All'
I think, the encoding of the log is wrong.
May be, you should check the property of the log writing of Apache Tomcat.
(see http://tomcat.apache.org/tomcat-9.0-doc/logging.html)
Hope, it should help you.
I just found out that weird output will only happens when I delete all the Startup logger in Catalina.out.
Example of Startup logger :
.
.
{some logger}
08-Aug-2019 15:15:22.692 INFO [main] org.apache.catalina.startup.Catalina.start Server startup in [33,192] milliseconds
If I just leave it, it will not give the weird output again.
So, I will close this issue.
I wonder if there is a way to see System.out.println Messages in Idea when I´m using Glassfish to handle Websocketconnections. I cant find an Output Window where my messages are displayed. So if this doesnt work: How do you log with this setup ?
My glassfish log is located in the glassfish window under debug when I run debug. System out messages will show up here in the log messages. You can also find them by navigating to your glassfish log file. My file is located at:
C:\glassfish4\glassfish\domains\domain1\logs\server.txt
And here is a pic of that same log in the debug screen. This screen pops up automatically for me when I start the debug server.
I am using log4j with very simple setup in an Eclipse plugin project, that I am building right now.
I call BasicConfigurator.configure(); in the main class and then just use log4j in every class like this:
private static final Logger logger= LogManager.getLogger(ClassName.class.getName());
That worked fine for a while but now I have problems with log4j. I am not sure what happened, but it seems the logging level is now Level.WARN. Also the console output is somewhat broken. The logging messages are logged two times each. One time normal, and one time really weird:
!ENTRY org.apache.log4j 2 0 2017-01-10 13:19:58.192
!MESSAGE package.ClassName - This is a logging message
0 [main] WARN package.ClassName - This is a logging message
I do not use a properties or xml file so I cannot imagine what I changed.
EDIT: I checked out an older point of the program and the problem still exists. That should mean it is not a problem of the code itself. Can Eclipse settings or something like that affect the console behavior?
EDIT 2: The idea of unchecking "Limit console output" did not help.
EDIT 3: These are my dependencies:
Require-Bundle: org.eclipse.ui,
org.eclipse.emf.ecore;bundle-version="2.12.0",
org.eclipse.emf.ecore.xmi;bundle-version="2.12.0",
org.eclipse.core.resources;bundle-version="3.11.0",
org.eclipse.core.runtime;bundle-version="3.12.0",
org.eclipse.jdt.core;bundle-version="3.12.1",
org.eclipse.jdt.launching;bundle-version="3.8.100",
org.junit,
org.apache.log4j;bundle-version="1.2.15"
EDIT 4: A clean Eclipse version fixes the output problem. But using the clean version would mean to install again all the plugins and tools. Also I would have to configure my preferences from scratch. Also perhaps that then causes the problem again, so I should rather find the cause of the problem.
Try removing the "trace_file" directive from the my_package logger statement.
Try this one
static {
PatternLayout layout = new PatternLayout();
String conversionPattern = "%d %-5p [%t] %c{2} (%2F:%M(%L)):%m%n";
layout.setConversionPattern(conversionPattern);
ConsoleAppender consoleAppender = new ConsoleAppender();
consoleAppender.setLayout(layout);
consoleAppender.activateOptions();
Logger rootLogger = Logger.getRootLogger();
rootLogger.setLevel(Level.INFO);
rootLogger.addAppender(consoleAppender);
}
I would like to add logs line in the "Error Log" view without printing those logs in the console, this because I want to manage the console log through log4j.
The idea is to use create a custom logger that:
Print the log in the console using log4j
Print the log in the "Error Log" view using Eclipse RCP features
Eventually show an error dialog to the user
I don't want the Eclipse RCP console log because in this case I'd have doubled logs in the console.
How can I add entries in "Error Log" View without print them in the console?
---UPDATE
With the console output i mean the messages formatted in this manner:
!ENTRY com.plugin.id 4 0 2014-10-15 11:37:04.314
!MESSAGE Error Messge
!STACK 0
---stack trace
I don't want to see these messages in the Console output but i only want to see the entry in the LogView:
Use the Eclipse ILog interface to write to the Eclipse log.
If your plugin has an Activator derived from Plugin (or AbstractUIPlugin) you can get the log using
Plugin.getLog();
You can also use
ILog log = Platform.getLog(bundle);
where bundle is your plugin Bundle - you can get this with:
Bundle bundle = Platform.getBundle("plugin id");
Once you have the ILog use
IStatus status = new Status(IStatus.ERROR, "plugin id", error code, "Message", throwable);
log.log(status);
Status has several constructors of varying complexity, I have show the most general.
For an Eclipse e4 application you can also use StatusReporter.
i log the messages in the log file using filehandler in xml format. log messages are stored successfully in the log file. but the log messages are still displaying in the netbeans command prompt.
how to stop displaying those log messages?
Review Your logger configuration and disable ConsoleAppender (if using log4j)
logger.setUseParentHandlers(false);
made me to stop the default root handlers and stops the logging in the console.
