I have a module which use **java webservices (JAX-WS)** in Client and Gateway scope.  
Works fine with Ignition 7.9.9 / Java 8 (Client/Gateway scope)  
This module don’t have any external dependency for webservices.

I upgraded to Ignition 7.9.10-beta / Java 9 on the Gateway (I use the JRE 9 provided by the client launcher)  
**Does the gateway Ignition 7.9.10 support Java 9 ???**

From Java 9, java webservices (JAX-WS) have been remove from JRE  
[http://openjdk.java.net/jeps/320](http://openjdk.java.net/jeps/320)  
and we need to add external dependency to run theses webservices.

I’ve tried to add various dependencies to replace those that are not packaged with JRE 9.  
Following this :

> <https://stackoverflow.com/questions/48204141/replacements-for-deprecated-jpms-modules-with-java-ee-apis/48204154#48204154>

But when my module create the webservice I always have the following error (Gateway Scope) :

```auto
javax.xml.ws.WebServiceException: Provider com.sun.xml.internal.ws.spi.ProviderImpl not found
```

if I add this in Ignition.conf, it solve the issue for the gateway scope,

```auto
wrapper.java.additional.7=--add-modules=java.se.ee
```

**but not in the client scope…is it possible to do the same whith args for the clientlauncher.exe ???**  
…Yes, seem just putting the parameter at the end do the job…

```auto
clientlauncher.exe gateway.addr=127.0.0.1:8088:8043 retries=3 scope=C project=MODULES windowmode=fullscreen --add-modules=java.se.ee
```

**I’m looking too for a better solution working too for Java 11 / Ignition 8.0…**

With Ignition 8 - Java 11,

the same module give the same error, despide of the dependecies for JAX-WS and more :

Is there anythings else in Ignition class loader process to explain this error ???

</div>

Wild guess here, but:

Try adding a `src/main/resources/META-INF/services/javax.xml.ws.spi.Provider` file containing the value `com.sun.xml.ws.spi.ProviderImpl` (note the lack of `internal` in that package).

Make sure this file ends up in the `META-INF` folder in the JAR of your built module.

Thanks @Kevin.Herron , I added the file in the common jar loaded for CDG scope. I think this file is at the right place in the jar : when I unzip it in the modl, can you confirm it’s ok or not ???

Looks right to me... I don't know if you missed anything, it was just a guess :-/

If I have still com.sun.xml. **internal**.ws.spi.ProviderImpl in my error og, I suppose that the file had not be used ?

</div>

I don’t think you need it, it looks like `jaxws-rt` jar already has it.

There’s probably some issue with ClassLoaders here. I’d try running this in IDE in debug mode and breakpointing in `javax.xml.ws.spi.FactoryFinder#find(String, String)`

Maybe the context ClassLoader needs to be set or unset when you try to instantiate a service.

It’s part of the `jaxws-api` jar, do you have that in your module?

Try setting the context ClassLoader to be your module’s ClassLoader or null?

```auto
Thread.currentThread().setContextClassLoader(MyModuleHook.class.getClassLoader());

```

Set that before you try to make a web service or whatever leads down that code path.

I've tried it in the GatewayHook::setup but I've still the issue 😫

```auto
    @Override
    public void setup(GatewayContext gatewayContext) {
        logger.info("setup()");
        this.context = context;
        Thread.currentThread().setContextClassLoader(GatewayHook.class.getClassLoader());

It needs to happen immediately before the call to create a WebService otherwise you might be setting the context ClassLoader on the wrong thread or it could get reset by some other code.

I will PM a link to DL my module source code if you could have a look at the at the POM.  
I probably attached to many dependencies for WS ?
