Robert F. Peake created OPENJPA-2791: ----------------------------------------
Summary: Parsing persistence.xml throws premature end of file error Key: OPENJPA-2791 URL: https://issues.apache.org/jira/browse/OPENJPA-2791 Project: OpenJPA Issue Type: Bug Components: build / infrastructure, jpa Affects Versions: 2.4.3 Environment: Linux Ubuntu 18.04 Reporter: Robert F. Peake XMLMetaDataParser in org.apache.openjpa.lib.meta uses the SaxParser to read persistence.xml. Just within the last few days, it has begun to throw this error: {quote}org.xml.sax.SAXException: [file:/home/robert/git/sccdata/target/classes/META-INF/persistence.xml|file:///home/robert/git/sccdata/target/classes/META-INF/persistence.xml] [Location: Line: 5, C: 64]: org.xml.sax.SAXParseException; systemId: [http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd]; lineNumber: 1; columnNumber: 1; Premature end of file. {quote} Resorting to XML Copy Editor to validate the schema shows the error actually involved: Fatal Error at line 0, column 0: unsupported protocol in URL. It seems that Oracle's web site has switched from HTTP to HTTPS, which is a protocol that parser cannot handle, as explained in this post: {color:#000000}[article|[https://knowledgebase.progress.com/articles/Article/Unsupported-protocol-in-URL-reading-XML-from-a-URI].]{color} {color:#000000} {color} {color:#000000}The problem has been reported elsewhere [Stack Overflow|https://stackoverflow.com/questions/56728487/org-xml-sax-saxparseexceptionpublicid-http-xmlns-jcp-org-xml-ns-persistence-p/56741356#56741356].{color} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
