CXF RESTful Client - How to do trust all certs?

This is from the CXF mailing list. Note that I didn't have to implement it due to other system updates, so this is theoretical:

WebClient webClient = WebClient.create(this.serviceURL,
    this.username,
    this.password,
    null); // Spring config file - we don't use this

if (trustAllCerts)
{
    HTTPConduit conduit = WebClient.getConfig(webClient)
        .getHttpConduit();

    TLSClientParameters params = 
        conduit.getTlsClientParameters();

    if (params == null) 
    {
        params = new TLSClientParameters();
        conduit.setTlsClientParameters(params);
    }

    params.setTrustManagers(new TrustManager[] { new
        DumbX509TrustManager() }); 

    params.setDisableCNCheck(true);
}

To complete the answer from sdoca, here is an implementation with a dumb X509 trust manager:

import org.apache.cxf.configuration.jsse.TLSClientParameters;
import org.apache.cxf.jaxrs.client.WebClient;
import org.apache.cxf.transport.http.HTTPConduit;
[...]

public class ApiClient {

    private WebClient webClient;
    [...]

    public void init() {

        webClient = createWebClient(URI).accept(MediaType.APPLICATION_JSON).type(MediaType.APPLICATION_JSON);
        addX509TrustManager();
    }

    private void addX509TrustManager() {
        Assert.notNull(webClient, "Client needs to be initialized");
        HTTPConduit conduit = WebClient.getConfig(webClient).getHttpConduit();
        TLSClientParameters params = conduit.getTlsClientParameters();

        if (params == null) {
            params = new TLSClientParameters();
            conduit.setTlsClientParameters(params);
        }

        params.setTrustManagers(new TrustManager[] { new BlindTrustManager() });
        params.setDisableCNCheck(true);
    }

}

Where BlindTrustManager is defined as follows:

import java.security.cert.X509Certificate;
import javax.net.ssl.X509TrustManager;

/**
 * This dumb X509TrustManager trusts all certificate. TThis SHOULD NOT be used in Production. 
 */
public class BlindTrustManager implements X509TrustManager {

    @Override
    public void checkClientTrusted(X509Certificate[] chain,
            String authType) throws java.security.cert.CertificateException {
    }

    @Override
    public void checkServerTrusted(X509Certificate[] chain,
            String authType) throws java.security.cert.CertificateException {
    }

    @Override
    public X509Certificate[] getAcceptedIssuers() {
        return null;
    }
}
