Validating xsd schema that contains import from external http source in Java 11

+2
−0

In the example.xsd file I have an import to an external xsd file that looks like this:

<schema xmlns="http://www.w3.org/2001/XMLSchema"
        targetNamespace="http://test.example.com"
        xmlns:wsi="http://ws-i.org/profiles/basic/1.1/xsd">
<import namespace="http://ws-i.org/profiles/basic/1.1/xsd" 
        schemaLocation="http://ws-i.org/profiles/basic/1.1/swaref.xsd" />
<element name="attachment" type="wsi:swaRef" />
</schema>

In the config file I have created the XsdSchema and validator beans

@Bean
public XsdSchema schema() {
  return new SimpleXsdSchema(new ClassPathResource("example.xsd"));
}

@Bean
public XmlValidator schemaValidator(XsdSchema xsdSchema) {
  return xsdSchema.createValidator()); // throws exception
}

when starting the server I get the following exception:

schema_reference: Failed to read schema document 'swaref.xsd', because 'http' access is not allowed due to restriction set by the accessExternalSchema property.

In order to solve the problem I have tried different things such as:

  • Setting System.setProperty("javax.xml.accessExternalSchema", "all");
  • Setting System.setProperty("javax.xml.accessExternalDTD", "all");
  • Creating jaxp.properties file under both jdk/lib and jdk/jre/lib and adding javax.xml.accessExternalSchema = all in there
  • Changing import in xsd to <import namespace="http://ws-i.org/profiles/basic/1.1/xsd"/> which then causes different exception - Cannot resolve the name 'wsi:swaRef' to a(n) 'type definition' component.

Java 11, Gradle 5.5.1, Spring Boot 2.1.6, jaxws-ri 2.3.2

how to get it to work?
