Need FallbackErrorHandler Example

I am trying to setup log4j to use a FileAppender as a fall back appender
for a JDBCAppender.  Are there some examples or documentation I could
look at?  

 

I took a crack at it but I am getting the warning: log4j:WARN Failed to
set property [backupAppender] to value "LocalFileAppender".

 

The relevant xml snippet look like this:

 

  <appender name="LocalFileAppender"
class="org.apache.log4j.FileAppender">

    <param name="file"
value="C:\\Sun\\AppServer\\domains\\domain1\\logs\\logging-output.xml"/>

    <layout class="org.apache.log4j.xml.XMLLayout"/>

  </appender>

 

  

  <appender name="JDBCAppender"
class="org.apache.log4j.jdbcplus.JDBCAppender">

            

    <errorHandler class="org.apache.log4j.varia.FallbackErrorHandler">

      <param name="BackupAppender" value="LocalFileAppender"/>

    </errorHandler>

 

            . . . 

 

  </appender>

    

 

Thanks for help,

--Ken

My only thought is creating your own appender, which would wrap both JDBC and file appenders, and try to instantiate one, and if it wails - try to instantiate the other.
