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.

譯文：
JavaSE 8包含包java.xml.soap。
JavaSE 9將包移動javax.xml.soap到模塊java.xml.ws。
與JEE（如共享的模塊java.xml.ws）包括在JavaSE的9，但
- 棄用用於去除從JavaSE中的未來版本，以及
- 不是默認模塊路徑上。
一個快速的解決方法是
- 使用JRE 8運行jar：$MY_JRE8_HOME/bin/java -jar my.jar或
- 為JRE 9添加模塊：java --add-modules java.xml.ws -jar my.jar
從長遠來看，使用類似模塊的JavaSE項目java.xml.ws必須像其他庫一樣明確地包含模塊。
