log4j with EJB: AccessControlException

[Josh Reeves <j....@lycos.com>]

Hello everyone!

If you have a minute, please, take a look at my problem and 
point me to the right direction.

Many thanks in advance!

Here is what I have.

I'm trying to get log4j working with EJB. And it does, as long as I
agree to the output to the console. But if my log4j.properties
changed to ( borrowed as is from the manual, but the file name):

<< start of file >>

log4j.rootCategory=debug, stdout, R

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

# Pattern to output the caller's file name and line number.
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n

log4j.appender.R=org.apache.log4j.FileAppender
log4j.appender.R.File=MeasurementAPP.log

log4j.appender.R.ImmediateFlush=true

log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n

<< end of file >>

I'm getting:

java.rmi.ServerException: RemoteException occurred in server thread; nested exce
ption is:
        java.rmi.RemoteException: Unknown exception; nested exception is:
        java.lang.ExceptionInInitializerError
java.rmi.RemoteException: Unknown exception; nested exception is:
        java.lang.ExceptionInInitializerError
java.lang.ExceptionInInitializerError: java.security.AccessControlException: acc
ess denied (java.io.FilePermission MeasurementAPP.log write)
        <<no stack trace available>>

An entity bean looks the following:

public
abstract
class MeasurementEJB implements EntityBean
{

	static
	final
	Category  CAT           = Category.getInstance( MeasurementEJB.class);

	static
	final
	String    LOG_FNAME     = "/MeasurementAPP.log";

	static
	{
		FilePermission  fp  = new FilePermission( LOG_FNAME,  "write");

		try
		{
			AccessControlContext  acc  = AccessController.getContext();
			acc.checkPermission( fp);
		}
		catch(  AccessControlException accEx)
		{
			accEx.printStackTrace();
			throw new EJBException( accEx);
		}

		PropertyConfigurator.configure(  "log4j.properties");
	} // static

...

	public
	Collection  ejbHomeGetMeasurementsInDate( Date  from, Date  to,
																						int quantity)
	{
		Vector  result  = new Vector();

		CAT.debug(  "In ejbHomeGetMeasurementsInDate.");

                ...
        } // end ejbHomeGetMeasurementsInDate

} // end of MeasurementEJB


log4j.jar is bound to the ejb-jar by being under META-INF/lib.

What would be your suggestion?
Also, log4j.configuration property: where it should be specified?

Best regards,
AR
