Unable to create Provider: class com.sun.xml.ws.spi.ProviderImpl cannot be cast to class javax.xml.ws.spi.Provider

I extracted a jar from a wsdl using the wsimport command (JDK 1.8).

Now, I'm trying to use that jar to execute a specific web service and it shows me this error:

Exception in thread "main" javax.xml.ws.WebServiceException: Unable to create Provider: class com.sun.xml.ws.spi.ProviderImpl cannot be cast to class javax.xml.ws.spi.Provider (com.sun.xml.ws.spi.ProviderImpl and javax.xml.ws.spi.Provider are in unnamed module of loader 'app')

    at com.Service01.<init>(Service01.java:42)
    at com.kyc.MainApp.main(MainApp.java:45)

Here are the dependencies that I have used in the pom.xml:

        <dependency>
            <groupId>javax.xml.soap</groupId>
            <artifactId>javax.xml.soap-api</artifactId>

        </dependency>

PS: I have tried these solutions below but neither one of them worked.

Solution

The things that needs to be cleaned up in the pom.xml.

Please remove all the jakarta dependencies as your code is using javax libraries.
Found out that jaxws-api version 2.1 (to be specific, versions <= 2.3.x) is not working with the jaxws-rt versions > 2.3.x if you are running your code on JDK versions > 1.8.

I have added scenarios on what issues I have encountered on JDK 17:

jaxws-api <= 2.1 and jaxws-rt > 2.3.x

This error will come:

Exception in thread "main" javax.xml.ws.WebServiceException: Unable to create Provider: class com.sun.xml.ws.spi.ProviderImpl cannot be cast to class javax.xml.ws.spi.Provider (com.sun.xml.ws.spi.ProviderImpl and javax.xml.ws.spi.Provider are in unnamed module of loader 'app')

jaxws-api >= 2.2.x and <= 2.3.x and jaxws-rt > 2.3.x

This error will come:

Caused by: java.lang.ClassNotFoundException: com.sun.xml.internal.ws.spi.ProviderImpl

Note: I saw that this issue only happens when you are running the code on JDK version > 1.8.

Better run your code on JDK 1.8 only. Then you will not get the above issues.

Otherwise, you stay within 2.3.x version for jaxws-rt for now if you want to run the code on higher JDKs.

Solution:

I have adjusted the POM to solve the issue (for JDK >= 1.8):

    <dependency>
        <groupId>javax.xml.soap</groupId>
        <artifactId>javax.xml.soap-api</artifactId>
        <version>1.4.0</version>
    </dependency>
    <dependency>
        <groupId>javax.xml.ws</groupId>
        <artifactId>jaxws-api</artifactId>
        <version>2.3.1</version>
    </dependency>
    <dependency>
        <groupId>com.sun.xml.ws</groupId>
        <artifactId>jaxws-rt</artifactId>
        <version>2.3.7</version>
    </dependency>
    <dependency>
        <groupId>WSIMPOTJAR</groupId>
        <artifactId>WSIMPOTJAR</artifactId>
        <version>1.0</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>javax.xml.bind</groupId>
        <artifactId>jaxb-api</artifactId>
        <version>2.3.1</version>
    </dependency>
    <dependency>
        <groupId>com.sun.xml.bind</groupId>
        <artifactId>jaxb-impl</artifactId>
        <version>2.3.9</version>
    </dependency>

This should work.
