The error msg is:
java.lang.AssertionError: org.xml.sax.SAXParseException; systemId: jar:file:/path/to/glassfish/modules/jaxb-osgi.jar!/com/sun/tools/xjc/reader/xmlschema/bindinfo/binding.xsd; lineNumber: 52; columnNumber: 88; schema_reference: Failed to read schema document ‘xjc.xsd’, because ‘file’ access is not allowed due to restriction set by the accessExternalSchema property.
the resolution is:
Create a file named jaxp.properties (if it doesn’t exist) under /path/to/jdk1.8.0/jre/lib and then write this line in it:
javax.xml.accessExternalSchema = all
