Log4j Logger - properties file configuration

Question

Hi
This is regarding Apache Log4j logger and the configuration of Log4j.properties file.
Suppose if I have set the properties file to log the messages in a database. It works fine.
However, lets say for some reason the database is not accessible for some time.
Is there a way to configure a "backup" feature in log4j.properties file that basically says that if database is not accessible then log to a temporary file somewhere, may be a text file on the user's system using the RollingFileAppender.

Hi,
you can all in the Application class:
Application.class.getResource( "log4j.properties" ) if its in the Application class package
Quote:
URL java.lang.Class.getResource(String name)
Finds a resource with a given name. The rules for searching resources associated with a given class are implemented by the defining class loader of the class. This method delegates to this object's class loader. If this object was loaded by the bootstrap class loader, the method delegates to ClassLoader.getSystemResource.
Before delegation, an absolute resource name is constructed from the given resource name using this algorithm:
If the name begins with a '/' ('\u002f'), then the absolute name of the resource is the portion of the name following the '/'.
Otherwise, the absolute name is of the following form:
modified_package_name/name
Where the modified_package_name is the package name of this object with '/' substituted for '.' ('\u002e').
Parameters:
name name of the desired resource
Returns:
A java.net.URL object or null if no resource with this name is found
Since:
JDK1.1
