I have created a Web Service using Spring. It works fine when running it on my embedded tomcat server. However when I package it as a JAR file and run it with java -jar
command, I am receiving this exception.
My service sends a simple soap request and the server response is:
"exception": "java.lang.NoClassDefFoundError",
"message": "javax/xml/soap/SOAPException",
That's the response I get in Postman.
Any ideas where I can look for the problem.
JavaSE 8 includes package java.xml.soap
.
JavaSE 9 moved package javax.xml.soap
to the module java.xml.ws
.
Modules shared with JEE (like java.xml.ws
) are included in JavaSE 9, but are
- deprecated for removal from a future version of JavaSE, and
- not on the default module path.
A quick workaround is to either
- run the jar with JRE 8: $MY_JRE8_HOME/bin/java -jar my.jar
, or
- add a module for JRE 9: java --add-modules java.xml.ws -jar my.jar
Longer term, JavaSE projects that use modules like java.xml.ws
must explicitly include the module like other libraries.

(Reproduced NoClassDefError and workarounds with zipped SOAP web service project at https://spring.io/guides/gs/producing-web-service/)
Adding the following in pom file solved the issue
<!-- https://mvnrepository.com/artifact/javax.xml.soap/javax.xml.soap-api -->
<dependency>
<groupId>javax.xml.soap</groupId>
<artifactId>javax.xml.soap-api</artifactId>
<version>1.4.0</version>
</dependency>
Yes, In Java 11 java.xml.soap was completely removed. java.lang.NoClassDefFoundError: javax/xml/soap/SOAPException can be removed by adding the following dependency.
<dependency>
<groupId>jakarta.xml.soap</groupId>
<artifactId>jakarta.xml.soap-api</artifactId>
<version>2.0.0-RC3</version>
</dependency>
But later, you will encounter , javax.xml.soap.SOAPException: Unable to create SAAJ meta-factory: Provider com.sun.xml.internal.messaging.saaj.soap.SAAJMetaFactoryImpl not found. This can be solved by adding the following dependency.
<dependency>
<groupId>com.sun.xml.messaging.saaj</groupId>
<artifactId>saaj-impl</artifactId>
<version>1.5.1</version>
</dependency>
Hope, it helps!
I imported this one to sort out the issue: https://mvnrepository.com/artifact/javax.xml.soap/javax.xml.soap-api/1.4.0
