症状

Startup failures occurring after installing a WAR instance of JIRA.  The following appears in the catalina.out:

java.lang.IllegalArgumentException: Invalid or unreadable WAR file

原因

This is due to a misplaced WAR file, or an incorrect file path in the jira.xml configuration file.

ソリューション

The WAR file path should be in <Tomcat-Install-Dir>/conf/Catalina/localhost/jira.xml.  If this file does not exist please create it along with the appropriate directory structure. 

A jira.xml template file can be found in <Extracted_JIRA_WAR_file>/etc/jira.xml.  You should list the WAR file path in the docBase attribute like below: 

<Context path="/jira" docBase="path/to/atlassian-jira-5.x.war" debug="0" useHttpOnly="true">
 
  <Resource name="UserTransaction" auth="Container" type="javax.transaction.UserTransaction"
    factory="org.objectweb.jotm.UserTransactionFactory" jotm.timeout="60"/>
  <Manager pathname=""/>
 
</Context>

The error should be corrected after fixing the path.  For more information check out the install guide here.
