Seems like the class <code>com.sun.xml.internal.ws.spi.ProviderImpl</code> is not available in <code>jdk-9</code>

<pre><code>jshell&gt; Class.forName("com.sun.xml.internal.ws.spi.ProviderImpl")

which is available in jdk-8, I wonder if you can use jdk-8 if possible might solve the issue.

It seems like you may need to include this dependency:

<pre><code>&lt;dependency&gt;
 &lt;groupId&gt;com.sun.xml.ws&lt;/groupId&gt;
 &lt;artifactId&gt;rt&lt;/artifactId&gt;
 &lt;version&gt;2.2.10&lt;/version&gt;
&lt;/dependency&gt;
</code></pre>

Or (haven't checked it yet but should work) you may need to change the scope to import for POM dependency.

<pre><code>&lt;dependency&gt;
 &lt;groupId&gt;com.sun.xml.ws&lt;/groupId&gt;
 &lt;artifactId&gt;jaxws-rt&lt;/artifactId&gt;
 &lt;version&gt;2.2.10&lt;/version&gt;

 &lt;scope&gt;import&lt;/scope&gt;

The first part of the answer by @reta works for me. These are the relevant dependencies from my pom (Java 10):

<pre><code>&lt;dependency&gt;
 &lt;groupId&gt;javax.xml.ws&lt;/groupId&gt;
 &lt;artifactId&gt;jaxws-api&lt;/artifactId&gt;
 &lt;version&gt;2.3.1&lt;/version&gt;
&lt;/dependency&gt;
&lt;dependency&gt;
 &lt;groupId&gt;com.sun.xml.ws&lt;/groupId&gt;
 &lt;artifactId&gt;rt&lt;/artifactId&gt;
 &lt;version&gt;2.3.1&lt;/version&gt;
&lt;/dependency&gt;

I've got the same problem upgrading to Java 11 from Java 8.
The problem was change of <a href="https://bugs.java.com/bugdatabase/view_bug.do?bug_id=JDK-8172726" rel="nofollow noreferrer">behavior in ForkJoinPool</a>, which classloader is as of jdk9 system classloader, not the main thread classloader, it can produce hard to solve ClassNotFound exceptions.
It's better explained in this answer <a href="https://stackoverflow.com/a/59444016/878015">https://stackoverflow.com/a/59444016/878015</a>

blocks|key|2351107|text|今天，在雅加达的时代，我需要以下两个依赖：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2351108|++++++++<dependency>

Today in the era of Jakarta, I needed the following two dependencies:

<pre><code> &lt;dependency&gt;
 &lt;groupId&gt;jakarta.xml.ws&lt;/groupId&gt;
 &lt;artifactId&gt;jakarta.xml.ws-api&lt;/artifactId&gt;
 &lt;version&gt;2.3.3&lt;/version&gt;
 &lt;/dependency&gt;

 &lt;dependency&gt;
 &lt;groupId&gt;com.sun.xml.ws&lt;/groupId&gt;
 &lt;artifactId&gt;jaxws-rt&lt;/artifactId&gt;
 &lt;version&gt;2.3.3&lt;/version&gt;
 &lt;/dependency&gt;
</code></pre>

One thing I find quite weird is that the second dependency is not from Jakarta, I thought all of these implementations were migrated. It works, but I'd appreciate if someone could comment on that.

Despite that I have defined the related dependencies as I have added below, getting the <code>java.lang.ClassNotFoundException: com.sun.xml.internal.ws.spi.ProviderImpl</code> exception when my app makes a call to the web service.

<pre><code>&lt;dependency&gt;
 &lt;groupId&gt;javax.xml.ws&lt;/groupId&gt;
 &lt;artifactId&gt;jaxws-api&lt;/artifactId&gt;
 &lt;version&gt;2.2.10&lt;/version&gt;
&lt;/dependency&gt;

&lt;dependency&gt;
 &lt;groupId&gt;com.sun.xml.ws&lt;/groupId&gt;
 &lt;artifactId&gt;jaxws-rt&lt;/artifactId&gt;
 &lt;version&gt;2.2.10&lt;/version&gt;
 &lt;type&gt;pom&lt;/type&gt;
&lt;/dependency&gt;
</code></pre>

p.s. The servlet container is <code>Apache Tomcat 9.0.4</code>.

p.s. Java version: <code>9.0.1</code>.
