What to do if a SAX Parser error occurs when using Liferay 7 / DXP on AWS
When running Liferay 7 / DXP on AWS, it is common to use S3 for the document & media repository, but at that time a SAX Parser error is thrown. To solve it, follow the procedure below.
- Create a file named system-ext.properties under / webapps / ROOT / WEB-INF / classes
- Insert the line org.xml.sax.driver = com.sun.org.apache.xerces.internal.parsers.SAXParser.
- After restarting the server, the error should no longer occur.
