Re: ClassNotFoundException trying to use JDBC appender

Re: ClassNotFoundException trying to use JDBC appender

Yes, getConnection() is static. Log4j isn't getting far enough to attempt calling it, though. An explicit call to LogDB.getConnection() is successful but Log4j's attempts to invoke it via reflection fails trying to load the class. That holds true even if I move my LogDB into the plug-in for my

log4j2 - Logger does not have the configuration If procured before LoggerContext has initialized

Hi, While upgrading from 1.2.17 to 2.5, I have come across a major difference. Please see following code snippets. Log4j1.2.17 private static final Logger LOGGER = Logger.getLogger(TestLog.class); public static void main(String args[]) { Properties p = new Properties();

Re: FileAppender dynamic fileName

To follow up, this worked as expected If system property "proc" is not defined then a file named "unknown.log" is created. This is documented in StrSubstitutor but may be good to emphasize on the lookups manual page. Sent from my iPhone > On 29 Nov 2016, at 10:05, Gary Gregory

Re: Switching log levels at runtime with log4j2

To further muddy the waters, the log4j-1.2-api module includes the classes org.apache.log4j.config.Log4j1* which provide partial support for Log4j 1.2 properties files. Gary On Tue, Nov 29, 2016 at 7:48 AM, Apache wrote: > > > > On Nov 29, 2016, at 8:20 AM, Jochen

ClassNotFoundException trying to use JDBC appender

I'm using Log4j2 in an Eclipse RCP application. I've been using a RollingFileAppender and am trying to switch to a JDBC appender backed by a ConnectionFactory. I've implemented this using the examples at https://logging.apache.org/log4j/2.x/manual/appenders.html#JDBCAppender as a guide but get a
