I'm trying to deserialize XML data into a Java content tree using JAXB, validating the XML data as it is unmarshalled:
try {
JAXBContext context = JAXBContext.newInstance("com.acme.foo");
Unmarshaller unmarshaller = context.createUnmarshaller();
unmarshaller.setSchema(schema);
FooObject fooObj = (FooObject) unmarshaller.unmarshal(new File("foo.xml"));
} catch (UnmarshalException ex) {
ex.printStackTrace();
} catch (JAXBException ex) {
ex.printStackTrace();
}
When I build the project with Java 8 it's fine, but building it with Java 11 fails with a compilation error:
package javax.xml.bind does not exist
How do I fix the issue?
This question is related to
java
jakarta-ee
jaxb
java-11
According to the release-notes, Java 11 removed the Java EE modules:
java.xml.bind (JAXB) - REMOVED
See JEP 320 for more info.
You can fix the issue by using alternate versions of the Java EE technologies. Simply add Maven dependencies that contain the classes you need:
<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.3.0</version>
</dependency>
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-core</artifactId>
<version>2.3.0</version>
</dependency>
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-impl</artifactId>
<version>2.3.0</version>
</dependency>
Instead of using old JAXB modules you can fix the issue by using Jakarta XML Binding from Jakarta EE 8:
<dependency>
<groupId>jakarta.xml.bind</groupId>
<artifactId>jakarta.xml.bind-api</artifactId>
<version>2.3.3</version>
</dependency>
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-impl</artifactId>
<version>2.3.3</version>
<scope>runtime</scope>
</dependency>
Use latest release of Eclipse Implementation of JAXB 3.0.0:
<dependency>
<groupId>jakarta.xml.bind</groupId>
<artifactId>jakarta.xml.bind-api</artifactId>
<version>3.0.0</version>
</dependency>
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-impl</artifactId>
<version>3.0.0</version>
<scope>runtime</scope>
</dependency>
Note: Jakarta EE 9 adopts new API package namespace jakarta.xml.bind.*, so update import statements:
javax.xml.bind -> jakarta.xml.bind
