Issue description

On a fresh JasperReports Server installation by default the log files located under .../WEB-INF/logs/jasperserver.log file. This location is configured in /WEB-INF/log4j.properties file in the following line:

log4j.appender.fileout.File=${jasperserver-pro.root}/WEB-INF/logs/jasperserver.log

Sometimes the log file is not created though. There are two common reasons for that.

Folder permissions

The most common cause for a missing jasperserver.log file that a system user does not have sufficient permissions to write into .../WEB-INF/logs folder. The permission have to be configured for the user which is running the Tomcat service (or any other application server where JasperReports Server is deployed)

webAppRootKey configuration

Another possible cause is that the webAppRootKey value in .../WEB-INF/web.xml file has been changed from 'jasperserver-pro.root' to something else. This can happen when the file has been modified manually, or when you have a script to perform the deployment, and that script is used a web.xml file template with a different value. The bottom line is that the value of webAppRootKey from web.xml:

<context-param> 

<param-name>webAppRootKey</param-name> 

<param-value>jasperserver-pro.root</param-value> 

</context-param> 

should match the value used to configure the location of jasperserver.log file:

log4j.appender.fileout.File=${jasperserver-pro.root}/WEB-INF/logs/jasperserver.log

In this case the value is 'jasperserver-pro.root', which is default
