B4J Question SLC throwing error

[elitevenkat]

I created a maven project using the below dependencies in pom.xml. When I try to compile this project into a B4J library using SLC, I get an error saying the simple-json package does not exists.

If org.json.simple is not part of the Java installation then SLC needs a 'libs' folder with that jar in it in order to reference it. This may be the problem.

As pointed by you, i had reconstructed the dir structure.
That error is gone.
I am able create the lib successfully in SLC.

java code 
    public boolean login(String clientID, String key) {
        requestPaths();
        setClientID(clientID);
        setKey(key);

/*

Response response = RestAssured.given()
                .headers(buildHeaders())
                .body(loginRequestBuilder(getClientID(), getKey()))
            .when()
                .post(data.get(0).toString())
            .then()
                .statusCode(200)
                .contentType(ContentType.JSON)
                .extract()
                .response();
        JsonPath jsonPathEvaluator = response.jsonPath();
        setCookies(response.getDetailedCookies());
        System.out.println(response.asPrettyString());
        setResId(jsonPathEvaluator.get("user_id"));
        
        return (jsonPathEvaluator.get("statusMessage").toString().toLowerCase()=="login successful");

    */

    return true;
    }
if  i remove the comment, error is thrown
if i retain the comment ,   xui.MsgboxAsync("Hello World!", ok)    ' the result is true in the title.
folder structure all the required external libs are in libs folder.

Which SDK are you trying to wrap?

Which SDK are you trying to wrap?

There is no 3rd party sdk. The jar was developed in ellipse java jdk 1.8.

 

[Erel]

Libraries shouldn't make http requests or deal with json. These are trivial features to implement in B4X.

Android doesn't support JavaFx. That looks like a desktop library

Yes it is for desktop b4j app only.

Yes. The process we are trying with the lib is to access Restapi from a 3rd party site. I pass user credentials (login id and pw).
In the response i get the cookies from the response header. This cookie value is passed in the subsequent post request.
To achieve this the lib was planed.
I don't know to do it b4j itself.

 

[Erel]

As I said, it is a mistake. It is trivial to make http requests with OkHttpUtils2.

In the response i get the cookies from the response header. This cookie value is passed in the subsequent post request.

It happens automatically.

Oops, sorry! ? Didn't notice this is a B4J thread - I'm too used to B4A questions.
