I'm trying to access a dummy REST API like https://reqres.in/api/users or https://jsonplaceholder.typicode.com/todos with a simple JAX-RS client like:
public class RandomDataProvider {
private WebTarget webTarget;
@PostConstruct
public void setUp() {
Client client = ClientBuilder.newBuilder()
.connectTimeout(5, TimeUnit.SECONDS)
.readTimeout(5, TimeUnit.SECONDS)
.build();
this.webTarget = client
.target("https://reqres.in/api/users");
}
public JsonArray getAllPosts() {
return this.webTarget
.request()
.accept(MediaType.APPLICATION_JSON)
.get(JsonArray.class);
}
}
but everytime I try to use HTTPS I get the SSLHandshakeExeption
that the server was: unable to find valid certification path to requested target:
[ERROR ] SRVE0283E: Exception caught while initializing context: javax.ws.rs.ProcessingException: javax.net.ssl.SSLHandshakeException: SSLHandshakeException invoking https://reqres.in/api/users: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

The Dockerfile looks like the following:
FROM open-liberty:microProfile3-java11
COPY --chown=1001:0 target/mywar.war /config/dropins/
I'm assuming that this official Docker image is using the JDK trusted certificates or do I have to configure this explicitly in an own server.xml
?
