XML Validation scenarios with JAXB in Spring Boot due to Schema Location guide
I'm not sure how to approach I've been struggling with this for a few days now and could really use some help. I'm experimenting with This might be a silly question, but I've been banging my head against this for hours. I'm currently working on a Spring Boot application where I need to validate an incoming XML request against an XSD schema using JAXB. However, I'm running into issues with the validation process. When I try to marshal the XML, I get the following behavior: ``` org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 1; cvc-elt.1: want to find the declaration of element 'request'. ``` The XML I'm trying to validate looks like this: ```xml <request xmlns="http://www.example.com/schema"> <name>John Doe</name> <age>30</age> </request> ``` And here is the XSD schema I'm using: ```xml <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.example.com/schema" xmlns="http://www.example.com/schema" elementFormDefault="qualified"> <xs:element name="request"> <xs:complexType> <xs:sequence> <xs:element name="name" type="xs:string"/> <xs:element name="age" type="xs:int"/> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> ``` In my Spring Boot application, I have set up a `Jaxb2Marshaller` like this: ```java @Bean public Jaxb2Marshaller jaxb2Marshaller() { Jaxb2Marshaller marshaller = new Jaxb2Marshaller(); marshaller.setContextPath("com.example.schema"); marshaller.setSchema(new ClassPathResource("/schemas/request.xsd")); return marshaller; } ``` I have verified that the schema is correctly included in the resources folder and is named `request.xsd`. However, the behavior indicates that the JAXB context is unable to find the declaration for the 'request' element. I've also tried removing the `setSchema` method, but that didn't resolve the scenario. Is there a specific configuration I may have missed for the JAXB marshaller to recognize the XML schema? Any suggestions on how to troubleshoot this scenario would be greatly appreciated! Could this be a known issue? This is part of a larger microservice I'm building. What would be the recommended way to handle this? I'm working on a CLI tool that needs to handle this.
