entity must be null for http method GET

Question

I'm trying to consume an external api exposed a payment provider. I user Jersey and javax.ws.rs for request, because I can easily send authent with Digest.

But when it comes to make the request, a GET with payload, Jersey returns

> IllegalStateException. Entity must be null for http method GET

CashTransactionResponse responseData = null;
//We connect to intouch server
String requestUrl = rootUrlTouchPay + agency.getAgencyCode() + "/" + IntouchMethodApis.TRANSACTION + "?loginAgent=" + agency.getLogin() + "&passwordAgent=" + agency.getPassword();

ClientConfig clientConfig = new ClientConfig();
//Open Digest authentication
HttpAuthenticationFeature feature = HttpAuthenticationFeature.digest(BASIC_LOGIN, BASIC_PWD);
clientConfig.register(feature);

clientConfig.register(JacksonFeature.class);
//Create new rest client
Client client = ClientBuilder.newClient(clientConfig);
clientConfig.property(ClientProperties.SUPPRESS_HTTP_COMPLIANCE_VALIDATION, true);
//Set the url
WebTarget webTarget = client.target(requestUrl);
Invocation.Builder invocationBuilder = webTarget.request(javax.ws.rs.core.MediaType.APPLICATION_JSON);

logger.info("Initialisation of cashout service successful for cash");

// create request
Gson gson = new Gson();
String transactionString = gson.toJson(cashRequest);

Response response = null;
// start the response
if (cashRequest.getServiceCode().contains(TelecomEnum.WAVE.name().toUpperCase())) {
    response = invocationBuilder.method("GET", Entity.entity(transactionString, javax.ws.rs.core.MediaType.APPLICATION_JSON));
} else {
    response = invocationBuilder.put(Entity.entity(transactionString, javax.ws.rs.core.MediaType.APPLICATION_JSON));
}

Please how could i do to send my GET request with body ?

Thanks

@user207421 i don't have access to the remote server, hosted by a bank provider. They created it like it. — Teddy Kossoko, Jun 30 '22 at 09:26

Instead of doing an invocationBuilder.method("GET", ...), use invocationBuilder.post(entity), as described here. This will allow you to POST your transaction String to the endpoint.

the remote server is waiting for GET that's why i send a GET. – Teddy Kossoko Jun 30 '22 at 09:25
that's fine, but then send the GET without a body. – Erik Pragt Jun 30 '22 at 13:49
the body must contain some data they use to process my request on server side. – Teddy Kossoko Jul 01 '22 at 14:02
I think there's a misunderstanding on your end. You either send the GET without the body, or a POST with body. So, why in theory you could send a body with a GET request, [it's never useful to do so](https://stackoverflow.com/questions/978061/http-get-with-request-body). – Erik Pragt Jul 02 '22 at 07:37

I believe the problem is in

Client client = ClientBuilder.newClient(clientConfig); clientConfig.property(ClientProperties.SUPPRESS_HTTP_COMPLIANCE_VALIDATION, true);

The client copied the values from clientConfig and any further settings on clientConfig do not have any impact on the client.

Either switch the lines or set the ClientProperties.SUPPRESS_HTTP_COMPLIANCE_VALIDATION property on the client.
