Logging
Your application can obtain a Logger object and write to the servlet log by calling the getApplicationLogger method of the E3ApplicationConfig interface. The logger level will be set as indicated by the parameters com.arbortext.e3.applicationLog.java.classname (classname is the Java class that implements the application), com.arbortext.e3.applicationLog.java, or com.arbortext.e3.applicationLog in e3config.xml. Refer to Parameters that Control Application Logging in Global Arbortext PE Request Manager Parameters for more information.
