Adriano buen día.

Desde el móvil tengo conección perfecta con mi base de datos sql server 2008, cuando quiero modificar un registro o actualizar me da el siguiente error:Exception in safecall method

Hi! Nice job on this tutorial!
I understood all the guidelines but how can i aproach the access to datasnap server without that proxy libraries? I mean, using tipical url queryng using json as output format?

Andreano, gostaria de parabenizá-lo pelo excelente tutorial.
Estou começando a desenvolver em Android agora e já consegui implementar o codigo sem problemas na API 10 (Android 2.3.3), infelizmente não consego em nenhume API lançada após a 10. Já quebrei a cabeça bastante mas não encontro solução. Gostaria de lhe pedir uma ajuda para esse caso. Fico muito grato.

Obrigado

Andreano, primeiramente quero parabeniza-los pelos post, muito util para a comunidade, gostaria de saber como posso fazer para compartilhar a function getConnection() com outras class, sem a precisar refazer a function em cada class, fazendo apenas a chamada, já tentei assim:
ClassConexao Conexao = new ClassConexao();
DSRestConnection conn = Conexao.getConnection();
Mas não funciona, se puder ajudar fico muito grato

In reply to giovanni. Giovanni, because on the second one I return the cursor through the TDBXReader, as the server finish to send the cursor to the client side it will be automatically destroyed by the server.

In reply to Andreano Lanusse. Andreano, I think is the eclipse system on my PC It just will not "talk" with the REST Server for some reason. calling the same address from a web browser works. but not from the Android emulator. I am trying to do the same in RADPHP and having problems with the DBXReader. I do not know how to access it. ??

Hi,
I followed your example to connect to datasnap and create an android app but it is not working on the android side. for some reason I does not post back to the table or refresh the data. It does work if i use a web page but not from eclipse. any Ideas?

Finnally got it:

conn.setHost(“192.168.2.5”);
conn.setPort(80);
conn.setUrlPath(“/TestRest.dll”);

Thanks

In IIS will be port 80 by default and try to call some server method, just http://192.168.2.5/TestRest.dll won’t do anything

In reply to Andreano Lanusse.

With a dll in an IIS server with the 8080? I thought the port was 80 as HTTP in IIS.

With IP and port 8080 doesn’t work. I compile the dll, put it in a server with other ISAPIs and no way i can’t get a connection in Java.

with http://192.168.2.5/TestRest.dll i get the default DataSnap REST Project webpage.

I don’t know if i’m doing something wrong.

Thank you very much… that’s a record time answer!

In reply to Anagnostes. setHost should be IP or hostname of the machine running the DataSnap Server and port should be 8080, unless you changed the default

What should be the setHost and setPort of the getConnection() funcion when you deploy the WebService as isapi dll?

I get “Host may not be null” all the time.

Thank you

In reply to statik0. @Statik0, You just need to import the WSDL on the Android side, google and you will find a lot of videos.
