2007-12-06 10:55:05,327 http-8080-Processor20 ERROR [500ErrorPage] Exception caught in 500 page Unable to compile class for JSP
org.apache.jasper.JasperException: Unable to compile class for JSP
	at org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:572)
	at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:305)

原因

The Tomcat container caches .java and .class files generated by the JSP parser they are used by the web application. Sometimes these get corrupted or cannot be found. This may occur after a patch or upgrade that contains modifications to JSPs.

ソリューション

1. Delete the contents of the <JIRA_INSTALL>/work folder if using standalone JIRA or <CATALINA_BASE>/work if using EAR/WAR installation .
2. Verify the user running the JIRA application process has Read/Write permission to the <JIRA_INSTALL|CATALINA_BASE>/work directory.
3. Restart the JIRA application container to rebuild the files.
