java.lang.NoClassDefFoundError : javax/xml/soap/SOAPException
提问by grangos
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 -jarcommand, I am receiving this exception.
我使用 Spring 创建了一个 Web 服务。在我的嵌入式 tomcat 服务器上运行它时它工作正常。但是，当我将其打包为 JAR 文件并使用java -jar命令运行它时，我收到此异常。
My service sends a simple soap request and the server response is:
我的服务发送一个简单的soap请求，服务器响应是：
"exception": "java.lang.NoClassDefFoundError",
"message": "javax/xml/soap/SOAPException",
That's the response I get in Postman.
这就是我在 Postman 中得到的回应。
Any ideas where I can look for the problem.
我可以在哪里寻找问题的任何想法。

JavaSE 8 includes package java.xml.soap.
JavaSE 9 moved package javax.xml.soapto the module java.xml.ws.
Modules shared with JEE (like java.xml.ws) are included in JavaSE 9, but are
- deprecatedfor removal from a future version of JavaSE, and
- not on the default module path.
JavaSE 8 包括包java.xml.soap.
JavaSE 9 将包移动javax.xml.soap到模块java.xml.ws.
与 JEE 共享的模块（如java.xml.ws）包含在 JavaSE 9 中，但
-不赞成从 JavaSE 的未来版本中删除，并且
-不在默认模块路径中。
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
一个快速的解决方法是
- 使用 JRE 8: 运行 jar $MY_JRE8_HOME/bin/java -jar my.jar，或者
- 为 JRE 9 添加一个模块：java --add-modules java.xml.ws -jar my.jar
Longer term, JavaSE projects that use modules like java.xml.wsmust explicitly include the module like other libraries.
从长远来看，使用类似模块的 JavaSE 项目java.xml.ws必须像其他库一样显式地包含该模块。

Yes, In Java 11 java.xml.soap was completely removed. java.lang.NoClassDefFoundError: javax/xml/soap/SOAPExceptioncan be removed by adding the following dependency.
是的，在 Java 11 中 java.xml.soap 被完全删除了。 java.lang.NoClassDefFoundError: javax/xml/soap/SOAPException可以通过添加以下依赖项来删除。
<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.
但是稍后，您会遇到，javax.xml.soap.SOAPException: Unable to create SAAJ meta-factory: Provider com.sun.xml.internal.messaging.saaj.soap.SAAJMetaFactoryImpl not found。这可以通过添加以下依赖项来解决。
<dependency>
<groupId>com.sun.xml.messaging.saaj</groupId>
<artifactId>saaj-impl</artifactId>
<version>1.5.1</version>
</dependency>
Hope, it helps!
希望能帮助到你！
