UnsatisfiedLinkError with SmartGWT library

I'm having some issues using the Smartgwt library. I've declared it in my pom.xml:

<!-- https://mvnrepository.com/artifact/com.google.gwt/gwt-user -->
        <dependency>
            <groupId>com.google.gwt</groupId>

            <artifactId>smartgwt</artifactId>
            <version>2.5-patch</version>
        </dependency>

I'm attempting to use the loadWSDL method here:

 XMLTools.loadWSDL(testURL, new WSDLLoadCallback() {
            
            @Override
            public void execute(WebService webService) {
                thirdPartyService = webService;
                
                RPCManager.setDefaultTimeout(5);
                login(testUserName, testPassword);
                
            }
        });

The necessary jars are within the Maven dependencies section in the build path:

enter image description here

However I keep getting this error when trying to debug:

Similar questions asked on here haven't yielded any results, just wondering if there's something obvious I'm missing here.

Thanks in advance

Solution

  • You are calling client-only code from the JVM, without using some kind of browser to emulate the JS that is required. This cannot work.

    The XMLTools class you are referencing is client-only code for use by GWT to compile to JS before it is used. The alternative to let you run some of the code in the JVM is to use legacy dev mode, which still requires a browser in which to invoke the JS (i.e. methods marked as native in the client code). As your stack trace shows, loadWSDL is a native method, so can only be called either when already in the browser, or in the context of legacy dev mode, while you are calling it on the server running in the JVM.
