note The full stack trace of the root cause is available in the Apache Tomcat/7.0.47 logs.

Apache Tomcat/7.0.47

Reason:

Something has corrupted your instance of Railo/Lucee. This may be the result of not enough space left on the server which results in the corruption of some of Railo/Lucee's XML files.

Solution:

Stop the following services:

• ElasticSearch
• Railo Tomcat/Lucee 
• SQBox Task Manager (14.0+)
• World Wide Web Publishing

Navigate to the folder where your WEB-INF folder resides (this may be within the WEBROOT folder, or within the WEBROOT/Intranet folder > rename this folder by adding '_BAK' to it

Start the 4 services listed above and navigate to the Railo/Lucee Web Admin portal

Default password can be provided by Support if needed. You can also reset the password if desired.

Follow the instructions listed on our Railo/Lucee Configuration article to add a Datasource, Mappings, and be sure to add your Mail Server information.

Confirm that you're able to access your intranet site
