Hey everyone. I’m getting the following error when trying to add Okta ApiClient to my Spring service.
The error is this:

***************************
APPLICATION FAILED TO START
***************************

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    com.okta.sdk.impl.client.DefaultClientBuilder.requestFactory(DefaultClientBuilder.java:471)

The following method did not exist:

    'void org.springframework.http.client.HttpComponentsClientHttpRequestFactory.setHttpClient(org.apache.http.client.HttpClient)'

The calling method's class, com.okta.sdk.impl.client.DefaultClientBuilder, was loaded from the following location:

    jar:file:/Users/filipe-lima/.m2/repository/com/okta/sdk/okta-sdk-impl/10.3.0/okta-sdk-impl-10.3.0.jar!/com/okta/sdk/impl/client/DefaultClientBuilder.class

The called method's class, org.springframework.http.client.HttpComponentsClientHttpRequestFactory, is available from the following locations:

    jar:file:/Users/filipe-lima/.m2/repository/org/springframework/spring-web/6.0.8/spring-web-6.0.8.jar!/org/springframework/http/client/HttpComponentsClientHttpRequestFactory.class

The called method's class hierarchy was loaded from the following locations:

    org.springframework.http.client.HttpComponentsClientHttpRequestFactory: file:/Users/user/.m2/repository/org/springframework/spring-web/6.0.8/spring-web-6.0.8.jar


Action:

Correct the classpath of your application so that it contains compatible versions of the classes com.okta.sdk.impl.client.DefaultClientBuilder and org.springframework.http.client.HttpComponentsClientHttpRequestFactory

if you check an example provided by okta, they have more dependencies, specifically this one might be required

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

Hey @phi1ipp , I’ve also tried with this one, but still got the same error.
My updated pom.xml looks like this:

Edit: I’ve cloned Okra’s example and added my service to connect to ApiClient, and it failed the same. Here’s my service (P.S: changed some personal info to show here):

ApiClient client = Clients.builder()
    .setOrgUrl("https://{yourOktaDomain}")  // e.g. https://dev-123456.okta.com
    .setClientCredentials(new TokenClientCredentials("{apiToken}"))
    .build();

Ah, so you are not up to doing any OIDC/OAuth protection. You need Okta APIs to manage objects in the tenant. Is it correct? If so, have you checked this documentation?
