jaxb xml schema-validation Java

I tried several approaches but none seem to work. I tried several approaches but none seem to work. Hey everyone, I'm running into an issue that's driving me crazy... I'm working on a Java application that processes XML files using JAXB for object mapping. I have an XML schema defined, and I want to ensure that the XML files adhere to this schema before processing them. However, I'm working with a `JAXBException` that reads: `com.sun.xml.internal.bind.v2.runtime.IllegalAnnotationsException`. This behavior occurs even when the XML seems to match the schema on the surface. Hereโ€™s a snippet of the XML Iโ€™m trying to validate: ```xml <employee> <id>123</id> <name>John Doe</name> <email>john.doe@example.com</email> </employee> ``` And my corresponding JAXB-annotated class looks like this: ```java @XmlRootElement(name = "employee") @XmlAccessorType(XmlAccessType.FIELD) public class Employee { @XmlElement(name = "id") private int id; @XmlElement(name = "name") private String name; @XmlElement(name = "email") private String email; } ``` I'm using JAXB 2.3.1 with JDK 8, and the schema is defined correctly. Iโ€™ve tried validating the XML against the schema using the `Schema` object but still encounter this exception. Iโ€™ve also attempted to enable verbose logging for JAXB but it didn't reveal any additional insights. How can I debug this scenario further? Any suggestions on how to ensure proper XML schema validation with JAXB? Thanks in advance for your help! For context: I'm using Java on Ubuntu. I'm working with Java in a Docker container on Windows 11. I'm developing on Ubuntu 20.04 with Java. Thanks, I really appreciate it! I'm using Java 3.10 in this project. What am I doing wrong?
