General

Q: I am having trouble running the samples, what can I do to debug them?

A: The following steps are generally useful for debugging the client/samples:

• Ensure the prerequisites for the OpenDXL JavaClient have been met.

• Switch the root logger from info to debug in the log4j.properties file located in the samples/src directory:

  log4j.rootLogger=info, stdout
  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

  Change to:

  log4j.rootLogger=debug, stdout
  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
