Reach a NetSuite RESTlet via OAuth

Question

The goal is to be able to call RESTlets using OAuth-header instead of NLAuth-header from my Java-application. In order to achieve it I took the following steps:

Answer 1

The steps seems to be correct as you are able to get consumer and user keys.

The probable error could be in your java code. I was able to get a successful response from a RESTLet using Java code. I used Scribe-Java as OAuth 1a client library.

Below is my main method

OAuthConfig authConfig = new OAuthConfig("CONSUMER_KEY", "CONSUMER_SECRET", null, SignatureType.Header, null, null);
    Token token = new Token("TOKEN_ID", "TOKEN_SECRET");
    OAuth10aServiceImpl auth10aServiceImpl = new OAuth10aServiceImpl(new NetSuiteApi(), authConfig);
    OAuthRequest request = new OAuthRequest(Verb.GET, "RESTLET_URL");
    request.setRealm("NS_ACCOUNT_ID");
    auth10aServiceImpl.signRequest(token, request);
    Response response = request.send();

you will also need to write NetSuiteApi class, as it is required by Scribe. Just, a framework overhead

import org.scribe.builder.api.DefaultApi10a;
import org.scribe.model.Token;

public class NetSuiteApi extends DefaultApi10a {

@Override
public String getAccessTokenEndpoint() {
    // TODO Auto-generated method stub
    return null;
}

@Override
public String getAuthorizationUrl(Token arg0) {
    // TODO Auto-generated method stub
    return null;
}

@Override
public String getRequestTokenEndpoint() {
    // TODO Auto-generated method stub
    return null;
}

}

Also, make sure that the user or user's has access to execute the RESTlet in its deployment.
