We are in difficult territory now. The error shows that the SAXParser does not recognize a property that OpenJPA is attempting to set before using the parser. Now, I ran a small test and my SAXFactory/Parser are same as yours. I am using JDK 1.5.
Please run the following code (preferably from a command-line) and see how it behaves in your environment. public void testParserProperty() throws Exception { SAXParserFactory factory = SAXParserFactory.newInstance(); SAXParser parser = factory.newSAXParser(); System.err.println(factory.getClass()); System.err.println(parser.getClass()); parser.setProperty("http://java.sun.com/xml/jaxp/properties/schemaLanguage", "http://www.w3.org/2001/XMLSchema"); } How are you running this program, from command-line or via Ant or other build facilities? ----- Pinaki Poddar Chair, Apache OpenJPA Project -- View this message in context: http://openjpa.208410.n2.nabble.com/problems-running-JPA-standalone-outside-of-container-tp6838028p6841194.html Sent from the OpenJPA Users mailing list archive at Nabble.com.
