Json-RPC Method from iOS to Android



I have a java webservice, with some method.





The webservice methods are in this form:







@Webservice(paramNames = {"email", "password", "stayLogged", "idClient"},

public Response startSession(String email, String password, Boolean stayLogged, String idClient) throws Exception {

boolean rC = stayLogged != null && stayLogged.booleanValue();

UserService us = new UserService();

User u = us.getUsersernamePassword(email, password);

if (u == null || u.getActive() != null && !u.getActive().booleanValue()) {

return ErrorResponse.getAccessDenied(id, logger);

}

InfoSession is = null;

String newKey = null;

while (newKey == null) {

newKey = UserService.md5(Math.random() + " " + new Date().getTime());

if (SessionManager.get(newKey) != null) {

newKey = null;

} else {

is = new InfoSession(u, rC, newKey);

if (idClient != null && idClient.toUpperCase().equals("ANDROID")) {

is.setClient("ANDROID");

}

SessionManager.add(newKey, is);

}

}

logger.log(Level.INFO, "New session started: " + newKey + " - User: " + u.getEmail());

return new Response(new InfoSessionJson(newKey, is), null, id);

}







The webservice can receive json-rpc calls, and the client-side code that can invoke the methods of the webservice, in iOS has this form:







-(void)asynchronousRPCWithMethod:(NSString *)method andParams:(NSArray *)params{



NSLog(@"REMOTE PROCEDURE CALL ON %@", method);

self.rpcMethod = method;



NSMutableString *requestString = [[NSMutableString alloc] init];



//setting method

[requestString appendFormat:@"{\"method\":\"%@\"", method];



//setting params

[requestString appendString:@", \"params\":["];



int max = [params count];

int c = 0;



for (NSString *str in params){

c++;

[requestString appendFormat:@"\"%@\"", str];

if (c==max){



}

else{

[requestString appendString:@", "];

}

}



[requestString appendFormat:@"], \"id\":1}"];



NSLog(@"Request:\n%@", requestString);



NSData *requestData = [NSData dataWithBytes:[requestString UTF8String] length:[requestString length]];



[requestString release];



NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:WEBSITELINK]] autorelease];



[request setHTTPMethod:@"POST"];

[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];

[request setHTTPBody:requestData];



NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:NO];

[conn scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSRunLoopCommonModes];

[conn start];



UIApplication *app = [UIApplication sharedApplication];

app.networkActivityIndicatorVisible = YES;



if (conn) {

NSMutableData *data = [[NSMutableData alloc] init];

self.receivedData = data;

[data release];

}

else {

NSError *error = [NSError errorWithDomain:RPCErrorDomain

code:RPCErrorNoConnection

userInfo:nil];

NSLog(@"*** error ***\n%@", error);

/**

* SENT A MESSAGE WITH A ERROR

*/

if ([self.delegate respondsToSelector:@selector(rpcDidFailWithError:)])

[delegate rpcDidFailWithError:error];



}



}







How can I implement the same client side method on Android???

div not scrolling properly with slimScroll plugin

I am using the slimScroll plugin for jQuery by Piotr Rochala Which is a great plugin for nice scrollbars on most browsers but I am stuck because I am using it for a chat box and whenever the user appends new text to the boxit does scroll using the .scrollTop() method however the plugin's scrollbar doesnt scroll with it and when the user wants to look though the chat history it will start scrolling from near the top. I have made a quick demo of my situation http://jsfiddle.net/DY9CT/2/ Does anyone know how to solve this problem?

Why does this javascript based printing cause Safari to refresh the page?

The page I am working on has a javascript function executed to print parts of the page. For some reason, printing in Safari, causes the window to somehow update. I say somehow, because it does not really refresh as in reload the page, but rather it starts the "rendering" of the page from start, i.e. scroll to top, flash animations start from 0, and so forth. The effect is reproduced by this fiddle: http://jsfiddle.net/fYmnB/ Clicking the print button and finishing or cancelling a print in Safari causes the screen to "go white" for a sec, which in my real website manifests itself as something "like" a reload. While running print button with, let's say, Firefox, just opens and closes the print dialogue without affecting the fiddle page in any way. Is there something with my way of calling the browsers print method that causes this, or how can it be explained - and preferably, avoided? P.S.: On my real site the same occurs with Chrome. In the ex
