No source code is available for type org.apache.log4j.Logger; did you forget to inherit a required module?

I want to create a logfile. So I added log4j 1.2.16 and did build Path

in log4j.properties wote code for consoleappender and rolling file.

in the Myclass

    private static Logger logger = Logger.getLogger(Myclass.class);

When i run the xeb application i get an error

 No source code is available for type org.apache.log4j.Logger; did you forget to inherit a required module?

Then in Myproject.gwt.xml i write this code

<inherits name="org.apache.log4j"/>

then i run my web applicaton *I can't see the URL in developmentMode"

Solution

LOG4J Doesn't Support GWT because LOG4J is used in Java/J2EE Apps Mainly for Console/File Logging. In case of GWT, the Java code you write down is actually compiled to JavaScript by the GWT Compiler. In that Case, the script won't be able to identify the logger type. I think you can use it for Server Package.

Try the Following Links for GWT Native Logging (This is Similar to console.log())

This API is also good in Logging for GWT. I recommend this
