Gathering additional logging information


IBM WebSphere or JSP engine logging provides more insight on issues where the  application is not successfully deployed. IBM Webserver or JSP engine logs also provide information about an un-handled run time exception or external factors such as Apache Tomcat issues.

The following table describes details about gathering additional information: 

Source

Location of logs

Apache Tomcat

Apache Tomcat logs are present in the <tomcat installation dir>\logs folder.

Default location:

Microsoft Windows:

c:\Program Files\Apache Software Foundation\Tomcat#\logs

UNIX:

/opt/apache/apache-tomcat#/logs

Hash (#) indicates the log file version.

Configuration files are available at the following location:

  • <tomcat installation dir>\conf\server.xml
  • <tomcat installation dir>\conf\web.xml
  • <tomcat instalation dir>\conf\Catalina\localhost\arsys.xml

Oracle WebLogic

Oracle WebLogic logging infrastructure supports a logger on each server that collects the log events generated by the application server. By default, logs are sent to the following three destinations:

Log File — Messages sent to the server Log file. 
Console 
— Messages sent to the Console.
Log Broadcaster 
— Messages sent to the Log Domain broadcaster.

By default, the server log file is located in the logs directory under the server instance root. DOMAIN_NAME\servers\SERVER_NAME\logs\SERVER_NAME.log.

For example, the log file for the Admin Server of the base_domain is C:\Weblogic\user_projects\domains\base_domain\servers\AdminServer\logs\AdminServer.log

IBM WebSphere

The WebSphere runtime logging covers the administration of the server and of the applications deployed on it. 
It is located in the $WAS_HOME/profiles/logs folder.

JBoss

JBoss logs include the server.log. The logs are located in the <jboss installation dir>/standalone/logs folder.

 configuration files

The  configuration files are located at the following location:

< installation directory>\WEB-INF\web.xml
< installation directory>\WEB-INF\classes\config.properties
