Tomcat 7.0.42 Error listenerStart

Deploy my war file to tomcat (jdk 7) and I see the following error. Not sure what causes the problem.

You can reconfigure java.utils.logging by adding /WEB-INF/classes/logging.properties to your military archive:

 org.apache.catalina.core.ContainerBase.[Catalina].level = INFO org.apache.catalina.core.ContainerBase.[Catalina].handlers = java.util.logging.ConsoleHandler

The actual error message should be visible. Also, check the application logs if you have already configured an additional logging structure (for example, log4j).

There may be a mismatch between the installed version of the JDK and the JDK with which you are trying to create your project.

1) If you use Eclipse .Go before Windows->Preferences->Compiler->check compiler compliance level (it must match the installed JDK)

2)

  • Right click on build.xml
  • Select Run As->Ant Build... Pay attention to the ellipsis !
  • Switch to JRE tab
  • Select jdk from the list

  • Create your own project
