Please help, Olingo Insert Entity Issue (400) Bad Request

[macsir]

Hi, All
Please help me on this this inserting operation, always get (400) Bad Request from line "req.execute()". Following is the original code and output.

public class OlingoCUD {
public static void main(String[] args) throws Exception {
String SERVICE_ROOT = "http://server:8001/api/v1/";
ODataClient client = ODataClientFactory.getClient();
String authStr = "username:pwd:NamespaceID";
String authEncoded = new String(Base64.encodeBase64(authStr.getBytes()));

ClientEntity newprocess = client.getObjectFactory().newEntity(new FullQualifiedName("ibm.tm1.api.v1.Process"));
newprocess.getProperties().add(client.getObjectFactory().newPrimitiveProperty("Name",client.getObjectFactory().newPrimitiveValueBuilder().buildString("MyProcess")));

URI ProcessURI = client.newURIBuilder(SERVICE_ROOT).appendEntitySetSegment("Processes").build();

ODataEntityCreateRequest<ClientEntity> req = client.getCUDRequestFactory().getEntityCreateRequest(ProcessURI, newprocess);
req.addCustomHeader("Authorization","CAMNamespace " + authEncoded);
req.setFormat(ODataFormat.APPLICATION_JSON);
ODataEntityCreateResponse<ClientEntity> res = req.execute();
System.out.println(res.getHeaderNames());

if (res.getStatusCode()==201) {
System.out.println("Successfully Created!");
}

}
}

Debug OutPut:

Anyone has ideas?

Try to "manually" POST your request through Chrome using the Advanced Rest Client plugin first to ensure you are forming the request correctly.
Trying it without setting any additional headers results in:

{
error: {
code: ""
message: "The content type specified is not supported. Please use JSON (application/json; charset=utf-8) as the content type."
}-
}


OK trying again with the right Content-Type and this body:

{
"Name": "TestProc"
}

Works -- I got 201 Created.

Try http://www.pocketsoap.com/tcpTrace/ to proxy your requests and see all of the traffic going back & forth (or enable wire logging).
Alternatively configure Eclipse to break on Null Pointer Exceptions and see what the response text is that is causing the null pointer exception.

Thanks, Man. Your tool is helpful! I will give it a go!
But I have implemented the new codes successfully using HttpClient and Gson in java for create/delete/update objects on TM1 server!

Good news! We are using Apache HTTP Client and Jackson.
