I'm trying to create a simple message using SOAP:

MessageFactory mf = MessageFactory.newInstance();

SOAPMessage message = mf.createMessage();

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.soap does not exist

How do I fix the issue?

解决方案

JAX-WS removed from Java 11

JAX-WS is no longer bundled with Java 11.

According to the release notes, Java 11 removed the Java EE modules:

java.xml.ws (JAX-WS, plus the related technologies SAAJ and Web Services Metadata) - REMOVED

Java 8 - OK

Java 9 - DEPRECATED

Java 10 - DEPRECATED

Java 11 - REMOVED

See JEP 320 for more info.

You can fix the issue by using alternate versions of the Java EE technologies. Simply add a com.sun.xml.ws : jaxws-ri Maven artifact that contains the technologies you need:

com.sun.xml.ws

jaxws-ri

2.3.2

pom

Jakarta EE 8 update (Mar 2020)

Instead of using old JAX-WS module you can fix the issue by using Jakarta XML Web Services from Jakarta EE 8:

jakarta.xml.ws

jakarta.xml.ws-api

2.3.3

com.sun.xml.ws

jaxws-rt

2.3.3

runtime

Jakarta EE 9 update (Nov 2020)

Use latest release of Jakarta XML Web Services 3.0:

compatible implementation jaxws-rt

jakarta.xml.ws

jakarta.xml.ws-api

3.0.0

com.sun.xml.ws

jaxws-rt

3.0.0

runtime

Note: change javax.* imports to jakarta.*
