RE: Mojarra logging messagse going missing

[12年前 に J S によって更新されました。]

Hi,

I'm finding that logging messages from the mojarra library aren't appearing in any of the tomcat or liferay log files. They did when the application was servlet based.

Mojarra uses Java SE Logging. I am currently finding that the PartialViewContextImpl class is catching an exception and logging it, but I never see the message. This is making tracking problems down quite hard!

I've tried making tomcat use log4j but this hasn't helped.

Is there an example of setting up logging in liferay with mojarra?

Thanks

John

Are you using PortletFaces Bridge? Liferay Faces Bridge has a new class named ExceptionHandlerAjaxImpl that might help with the logging issue you mentioned. It should be registered automatically if you have the liferay-faces-bridge-impl JAR in your portlet's WEB-INF/lib folder.

I'm using


<dependency>
<groupId>com.liferay.faces</groupId>
<artifactId>liferay-faces-bridge-impl</artifactId>
<version>3.0.0-BETA1</version>
</dependency>
<dependency>
<groupId>com.liferay.faces</groupId>
<artifactId>liferay-faces-alloy</artifactId>
<version>3.0.0-BETA1</version>
</dependency>


Log messages from my app come out ok, just the ones from the mojarra library. I can step over it in the debugger and see it go into the method, but somehow it's not coming out in the log file.

Thanks,

John

If you set a breakpoint in ExceptionHandlerAjaxImpl at line 62, does line 62 get reached?

if (throwable != null) {
	logger.error(throwable); // LINE 62
}

No, because the exception is handled just by logging it, it doesn't get queued. It's this bit in PartialViewContextImpl.processPartial

            try {
                processComponents(viewRoot, phaseId, executeIds, ctx);
            } catch (Exception e) {
                if (LOGGER.isLoggable(Level.INFO)) {
                    LOGGER.log(Level.INFO,
                           e.toString(),
                           e);
                }
            }

where logger is a java.util.logging.Logger

I'm sure it's just a configuration issue, but I can't work out what!

Maybe give SLF4J (with log4j as the impl) a try:

It seems like you have to explicitly assign a handler in your webapp, the normal defaults don't seem to apply:

in WEB-INF/classes/logging.properties

javax.enterprise.resource.webcontainer.jsf.handlers = java.util.logging.ConsoleHandler
javax.enterprise.resource.webcontainer.jsf.level = DEBUG

Thanks for your help,

John

Thanks John -- that's terrific info! I'm going to add this to the demo portlets. See FACES-1187
