Validating xml against xsd file generated through JAXB and XSD build option in eclipse

问题


I am trying to have a sample code for validating my xml file against xsd file, which is getting generated through jaxb and xsd build through Eclipse.

I am trying to do a sample validator file, that validates my xml against my xsd file. Now, I have found a lot of examples for the java code, and I am using one of them. Also I have recieved a lot of answers for the issue that I am facing, but some way the answers suggests to either update my xsd or xml file. For me, I cannot do any of these, as I am generating the xsd files through jaxb and xsd build option through Eclipse.

try {
SchemaFactory factory = 
SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Schema schema = factory.newSchema(new File(xsdPath));
Validator validator = schema.newValidator();
validator.validate(new StreamSource(new File(xmlPath)));
} catch (IOException e) {
System.out.println("Exception: "+e.getMessage());
return false;
} catch( SAXException e){
System.out.println("Exception: "+e.getMessage());
return false;
}
return true;
}

My XML File
<!DOCTYPE MLIspec SYSTEM "MLIspec-1.6.dtd">

Below is the error that I am receiving Exception: src-resolve: Cannot resolve the name 'SourceAccountIdentifier' to a(n) 'type definition' component.

Also, I tried to remove SourceAccountIdentifier from my xsd definition, to see if it fails anywhere else, in that case, I recieve the below error

Exception: src\main\java\com\citi\cbol\test\MLIspec-1.6.dtd (The system cannot find the file specified)

Please help to provide some solution for the error. Thanks!!

The generated code is on github for you.

I'm gussing that it's a problem with the xml or xsd files -- but I don't know for a fact.

I removed the dtd for now, here's what I have so far:

The tools are trang and xjc which install on Ubuntu Linux easily enough. Here's how to run the project, which builds from the console:

That should work even from Eclipse. Note that it's using gradle, or the Gradle Kotlin DSL for the build file, which Eclipse should be able to handle. Probably you want to import as a gradle project.

You should only have to alter the properties.xml file for your system; the source code should be fine.
