Re: Getting started with log4j...
I'm new to log4j, but had similar problems sporadically. You are
configuring log4j programmatically, while I was using a config file. It
wasn't finding my config file until I learned that the log4j.xml file
needs to be somewhere in the classpath (even if it's just ".") or
explicitly referenced via a DOMConfigurator.configure(filename) for
log4j.xml, or PropertyConfigurator.configure(filename) for
log4j.properties, call. I was getting a cryptic (to me) error message.
Hopefully, an expert will chime in with more authoritative help.

is being executed because it appears in a stack trace from an
exception that is generated shortly after the logging code.
In my logging code I create a Logger, create a Layout, and then create
a FileAppender passing a simple layout, the name of a text file, and a
boolean value of true. I then associate the FileAppender with the
Logger and write two messages.
When I open the text file identified in my code it is empty.
What step am I missing? (I create a text file with the correct name
before executing the logging code.)
Thanks in advance for the help.
Scott Huey,
P.S. - I'm using the latest stable release of log4j, Eclipse 3.2.1 and
my operating system is Microsoft Windows.
Here is some of my logging code:
/*
* Set up logging code here.
*/
Logger myLogger =
Logger.getLogger(com.vividsolutions.jump.workbench.ui.LayerViewPanel.class);
SimpleLayout layout = new SimpleLayout();
FileAppender appender = null;
try
{
appender = new FileAppender(layout, "debug_log.txt", true);
}
catch(Exception thisException)
{
System.err.println(thisException.getMessage());
}
myLogger.addAppender(appender);
Iterator loopThrough = contentIDs.iterator();
myLogger.info("This is a test.");
while(loopThrough.hasNext())
{
Object contentID = loopThrough.next();
Class contentIDClass = contentID.getClass();
String className = contentIDClass.getName();
myLogger.fatal("The class we couldn't find a renderer for was: "
+ className);
}

James,
I'll try reading about that.

JDBCAppender inserts %d instead of the date in the database
Hi All,
I am trying to use the log4j.jdbcplus.jdbcappender to log my messages to
an oracle database. I am not getting any errors and data is being
inserted into the database except that instead of actual logs %c, %d, %p
and the like are being inserted.
I have tried to use the jdbc.jdbcappender and that logs the messages
correctly in the database.
The file below is my properties file.
log4j.appender.D=org.apache.log4j.jdbcplus.JDBCAppender
log4j.appender.D.url=jdbc:oracle:thin:@dbname:1521:TSSD
log4j.appender.D.dbclass=oracle.jdbc.driver.OracleDriver
log4j.appender.D.username=user_name
log4j.appender.D.password=password
log4j.appender.D.sql=INSERT INTO SDR_EXCEPTIONS(CREATED_AT, CLASS_NAME,
PRIORITY, MESSAGE) VALUES ('%d{DATE}','%c','%p','%m')
log4j.appender.D.layout=org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern=[%t] %m
%l##%d{dd.MM.}#%d{HH:mm:ss} log4j.appender.D.layoutPartsDelimiter=#
log4j.appender.D.buffer=1
log4j.appender.D.commit=true
log4j.appender.D.quoteReplace=true
log4j.appender.D.throwableMaxChars=3000
I would appreciate any help
Thanks
Amin
