[Tomcat Error] SEVERE: Error listenerStart

System version: CentOS 6.6 x64

java version: 1.7.0_55

 

Problem Description:

An error appears in the log after the migration Tomcat project is started, and the content is as follows:

Jan 20, 2018 7:02:50 PM org.apache.catalina.core.StandardContext startInternal
SEVERE: Error listenerStart
Jan 20, 2018 7:02:49 PM org.apache.catalina.core.StandardContext startInternal
SEVERE: Context [] startup failed due to previous errors
Jan 20, 2018 7:02:49 PM org.apache.coyote.AbstractProtocol start
INFO: Starting ProtocolHandler ["http-bio-8680"]
Jan 20, 2018 7:02:49 PM org.apache.catalina.startup.Catalina start
INFO: Server startup in 30535 ms

The key information cannot be obtained from the above content, which only prompts that there is an error but does not indicate the point of failure. At this time, we need to modify the log level to print more information to help us troubleshoot. The method is as follows.

 

solution:

In the classes path of the tomcat project, add the following content to the file logging.properties , if there is no such file, create it directly.

handlers = org.apache.juli.FileHandler, java.util.logging.ConsoleHandler  
org.apache.juli.FileHandler.level = FINE  
org.apache.juli.FileHandler.directory = ${catalina.base}/logs  
org.apache.juli.FileHandler.prefix = error-debug.   
java.util.logging.ConsoleHandler.level = FINE  
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter

Next restart Tomcat, and then check the log, the problems I encountered are as follows:

Jan 20, 2018 7:07:20 PM org.apache.catalina.core.StandardContext listenerStart

Use the above information to confirm that the problem is on the database connection. After re-modifying the connection information, restart Tomcat, and “SEVERE: Error listenerStart” does not appear again.
