  1. POWant to get all Errors List when I validate XML using JAXB
    text
    copied!<p>Can you please help me to get the list of all errors when I validate the XML file using JAXB?</p> <p>Right now I have already implemented the code for the same. I have implemented the code using unmarshalling the XML file. </p> <p>When I unmarshalling the XML file at that time if any error would be there in the XML file, I got the exception but it came out after giving the first exception but I want the list of all errors of that XML file. This should not come out after getting the first error.</p> <pre><code>Source xsdFileName = new StreamSource(new File("validate6.xsd")); Source xmlFileName = new StreamSource(new File("test3.xml")); try { SchemaFactory sf = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
