HttpConnection.getResponseCode - MIDP bug?

Hi!
Try the following:
-make some example trying to connect to a valid Url...
-verify your connection...
-now make sure that is working properly.
-turn off your Ethernet cable or ISP connection
-Try to run the same example now.
The IOException is raised.... Iwonder Why??? The returned response code should be 503 HTTP_UNAVAILABLE .... Is this a MIDP bug or am I missing something?
public boolean verifyConnection(HttpConnection conn) throws IOException
          boolean res=false;
          if (conn==null)
               sConError="Null Connection";
               res=false;
          else
//System.out.println("1a" + conn.getURL() + conn.getResponseMessage());
               int rc;
               rc=conn.getResponseCode(); //Here's the problem when I'am not connected to the internet and try to make a Connection to an outside Site....
               sConError="";
               switch( rc )
                    case HttpConnection.HTTP_OK:
                         res=true;
                         break;
                    case HttpConnection.HTTP_TEMP_REDIRECT:
                         res=true;
                         break;
                    case HttpConnection.HTTP_ENTITY_TOO_LARGE:
                         res=false;
                         break;
                    default:
                         sConError=conn.getResponseMessage();
                         res=false;
                         break;
System.out.println("3a");
          return res;

I could be wrong on this....
The response code comes from the web server. If you disconnect your internet connection your MIDlet is no longer able to establish a connection to the web-server therefore it gets an IOException.

HttpConnection.getResponseCode() return -1

Hi guy's
I am developing a midp application which is communicate with server and display the result on the client using HttpConnection.Basically i am from bangalore,India and using Airtel,Vodafone connections for GPRS. My jar file is properly working in the Sony Ericsson models(k800i,k310i) with airtel and vodafone connections. But the same jar file is failed to communicate with server in Nokia models. HttpConnection.getResponseCode() return -1 in Nokia 6020,6070,6300 devices. Even N6030 is also return same value with vodafone. But same time application working fine in another 6030 model with airtel. Please look at my source code below.
private static String requestToServer(final String url, final String data)throws IOException {

result = true;
break;
default:

return result;
In the Nokia models, the httpCon.getResponseCode() return -1. Can anybody tell me, whats the problem and what the solution for this please.

IOException when trying to read HttpConnection input (MIDP 2.0-CLDC 1.0)

Hello!
I'm using the Java ME Platform SDK 3.0, on a Windows XP machine.
The midlet's code runs successfully with the emulator, but when i execute it on my motorola c650 (MIDP 2.0-CLDC 1.0), whenever i call the getInputStream method, it hangs for a while (say, 1 second), and then i get an IOException at that point.
I already tried:
- call getResponseCode before; i get an IOException at that point
- use POST method instead of GET
- call openOutputStream before openInputStream
- use getDataInputStream instead of getInputStream
HttpConnection c = (HttpConnection)Connector.open(url);
c.setRequestMethod(HttpConnection.GET);
InputStream is = c.openDataInputStream();
...Nothing helps... but the same code works on a motorola v3 black (MIDP 2.0-CLDC 1.1)
Thanks in advance!

Oh,
these are a little bit old handsets, aren't they?
Anyway I can remember that especially on C650 we've experienced some firmware issues. However if this happens also on V3 I can only recomend to check the access point configuration. These old motorolas must be set up correctly and differently for using internal browser (using a WAP access point) and differently for using from within Java applications (using an internet access point).

HttpConnection.getResponseCode generates a Connection Refused exeption

I have the following problem:
I connect to a webserver, this works fine. Then I write data to the webserver, this also works fine. After writing the data, I determine the http response code to see if everything was successfull. Every so often this generates a "connection refused" exception. This happens even after the connect and the write were successfull. I find this strange, since I was able to connect and write data (this data has arrived at the server because I can log it there without a problem).
Can anyone explain this behaviour to me, because I am lost here.
Mark

Have found that wildcard addresses matches any address of the local system, and that in IPv4, the wildcard address is 0.0.0.0. Can check for this with InetAddress.isAnyLocalAddress().
This means that I could potentially handle these cases by adding code to "ping" a host such as "tigers.com.au" using
InetAddress address = InetAddress.getByName(name);
if (InetAddress.isAnyLocalAddress() {
.... do something, eg raise exception
}But this is not fully satisfactory, as I would rather know that a "connection refused" exception is raised, which is actually the case with "tigers.com.au" (as all the browsers seem able to detect). I am not entirely sure what the relationship is between a site that has "connection refused" and it returning an ip address of 0.0.0.0. I don't think they are synonymous.
Any thoughts?

HttpConnection hangs in my T630. Please Help !

Hi all,
I`ve noticed this problem in a few threads on this forum, but none of them seem to have a definitive answer. Maybe we can answer it once and for all here :-) Any help would be greatly appreciated.
I`m trying to load a web page from a midlet in my T630. As I don`t really want to pay for call charges during development, I`m using the "Device Explorer" and the "Connection proxy" to try and connect to the internet using my broadband connection. I'm using the SonyEricsson developer kit (version 1) and I'm using a bluetooth serial connection on COM5 for the connection proxy.
I've based my code on some sample code from Sun to load some info from a web page. This code was even published to get around the IO blocking problem that I seem to be getting still !
The problem is when I try and use the HttpConnection.getResponseCode() method. Using the advice of other internet resources, I`ve put this code in its own thread. When I call HttpConnection.getResponseCode(), my T630 then pops ups with a menu, offering me these 3 options:
Allow Web access
Ask per access
Deny Web access
When this happens, it`s as if the thread running the getResponseCode() method blocks, and the T630 OS takes over. When I select an item from that menu, control does not pass back to the thread running getResponseCode(), but goes to the main midlet thread. Once I`m back in the main midlet thread, I don't know how to wake up the url loading thread. Does anyone have any ideas.
My debugging statements produce the following before the app hangs:
url=http://java.sun.com
conn=com.sun.midp.io.j2me.http.Protocol@e4857a1d

Hi, Paulgrime:
These days I also have struggled with the problem.
I just saw a java example from SUN site, which does not use getResponseCode(). It seems a good work around.
I tried that way and works fine. Only thing is you have to figure out the response status by analysing the inputstream content, which is actually easy.
So I go this way now.

HttpConnection Charset

Hello guys!
I tried a lot of times to send chinese characters using HttpConnection in j2me, but I have failed. :(
I tried in this way: I wrote a MIDlet using the HttpConnection, but when the data arrived in the servlet, the servlet receives a <null> String or an other character.
I ask to a friend, and he told me to change the charset using setRequestProperty methos in the HttpConnection.
I changed all values using the charset values from: http://a4esl.org/c/charset.html
but I have failed again, sometimes the MIDlet send a null String, sometimes I got a java.io.UnsupportedEncodingException...
If I sent the characters from the servlet directly to the MIDlet, woks... but I want to get the values from the MIDlet first, and them send the response...
Can anybody help me with this problem?
Thanks in advance.

I do not think its a probelm with not specifying encoding format in input stream . I have done a small test for it . I have commented my code of reading the input stream and have just used httpconenctin.dosconnect .
I ahve changed my code to following
for(loop)
String xml request = "xml request..n"
URL url = new URL(Config.getProperty("url"));
URLConnection connection = url.openConnection();
HttpURLConnection httpConnection = (HttpURLConnection) connection;
httpConnection.setDoOutput(true);
httpConnection.setDoInput(true);
httpConnection.setRequestMethod("POST");
httpConnection.setRequestProperty("Content-Type",
"application/soap; charset=\"utf-8\"");
OutputStream stream = httpConnection.getOutputStream();
stream.write(request.getBytes());
stream.close();
log.debug("Teturned from server::::::::::::::"+ httpConnection.getResponseCode() + "message"
+ httpConnection.getResponseMessage());
httpConnection.disconnect();
}Even with this .. iam getting socket reset exception for multiple requests. The curios part is for sirst request i get the response, but for second request it fails .

HTTP POST to PHP server problem

Hi, im trying post a long string to php from a MIDLET, but i have some problems. When i send the whole String, my php server cant receive the request (i have not any response), but, if the string that i send is 1/5 from the original, the process is successful correctly. have somebody any idea?
thx

this is my problem, extracted from another topic on this forum:
"Hi everyone.
I have a problem, and hope someone may help me.
My midlet is uploading sizeable data via http POST.
I'm using WTK104, since i need MIDP1.0
The code have been tried on DefaultGrayPhone emulator
and add-on Nokia's Series 60 Emulator.
Both emulators chunck data, however in different ways.
Deafult one simply produces wrong chunk length (possibly a bug),
Nokia's one always chunks by equal offsets of 2016 bytes.
I'm not using flushing, just close. All the data is being send
at once by one output stream write call.
So I believe (after proper investigation) that MIDP will use chunked Transfer-Encoding method whatever
on such sizeable a data as mine is (up to 50KB) and there's no way to override this behaviour.
Here the main problem appears - Apache refuses to accept chunked encoding in request. The corresposnding message is given in error log
*chunked transfer encoding forbidden*. The returned code is 411 - Content-Length requred. I see no way to override this behaviour of Apache. I was trying to upload my data into Zope web-server, which is my primary goal, but it doesn't handle chunked request either.
Has anyone faced the same problem? Who has managed to POST sizeable data from midlet? Which web servers did you use for that?
Any inputs are highly appreciated!
Anton"
Another:
"> So I believe (after proper investigation) that MIDP
will use chunked Transfer-Encoding method whatever
on such sizeable a data as mine is (up to 50KB) and
there's no way to override this behaviour.Is this true? When I try to set the content-length headers and then write a large byte[] to the output stream I got from an HttpConnection, the HttpConnection appears to remove the content-length header altogether and automatically sets the transfer-encoding to chunked.
Note- I am not calling flush on the outputstream, but I am calling httpconnection.getResponseCode, which I believe calls flush on the outputstream.

I have the identical problem.

J2ME network error

hi! i'm doing a small app for mobile devices, with j2me, netbeans5.0+mobility pack.
the problem is
String url = "http://www.google.ro/";
try {
      HttpConnection httpConnection =
            (HttpConnection) Connector.open(url, Connector.READ);
      if (httpConnection.getResponseCode() == HttpConnection.HTTP_OK) {

        // doing some more of something
} catch (Exception e) {
          e.printStackTrace();
}javax.microedition.io.ConnectionNotFoundException: TCP open
this is what i get when the program reaches httpConnection.getResponseCode() . i read that it's because a connection could not be established, or somethink like this, maybe because of a firewall or something else.
well, it so happens i connect to the internet through a proxy. but i tried starting the app with parameters like:
-Dhttp.proxyHost=192.168.xxx.xxx -Dhttp.proxyPort=8080
yet it still doesn't work. i get the same error.
what am i doing wrong? please help.
thank you

i tryied the same project with java wireless tookit, because it has proxy settings. however, i still get an error:

How to get the Response Code when a URL is launched from Web Dynpro

Hello Experts,
I have a Web Dynpro Application in which in one of its views i have an IFrame UI element in which i will show a resource stored somewhere ..
But before showing it i want to check if the resource actually exists. For this i have to check the HTTP Response code from Web Dynpro Application without setting it in the Iframe..
I am using the following code to get the Response Code:
try{
URL url = new URL("Some Url");
HttpURLConnection.setFollowRedirects(false);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.connect();
wdComponentAPI.getMessageManager().reportSuccess("Response code ="+connection.getResponseCode());
}catch(Exception e){
wdComponentAPI.getMessageManager().reportSuccess("Exception");
Now the Problem is whatever response Code occurs 403 (for No Proper Authorization), 404 (for Resource not found) etc..
i always get Response Code= 500 (which is for Internal Server Error) shown in the messgae i have printed.
Please let me know the correct way of getting the Response Code from Web Dynpro.
Also my resource is lying on a SAP Portal 6.4
Best Regards
Sundeep

Hi,
Check this code from /thread/5242768 [original link is broken] if it works.
try{
URL myurl = new URL("http://calendar.google.com");
URLConnection connection = myurl.openConnection();
if(connection instanceof HttpURLConnection) {
HttpURLConnection httpConnection = (HttpURLConnection) connection;
HttpURLConnection.setFollowRedirects(true);
httpConnection.setRequestMethod("HEAD");
httpConnection.connect();
System.out.println("Response = "+httpConnection.getResponseCode());
catch(Exception e) {
// print exception

HttpURLConnection , Response Code : 404 for HTTP method HEAD 302 for GET

After establishing the connection For the URL : http://calendar.google.com/ the response code is different for different HTTP METHODS.
For the method HEAD the response code is 404
For the method GET the response code is 302
Ideally according to W3 standards the header part for both methods should be same.
www.w3.org/Protocols/rfc2616/rfc2616-sec9.html
Unfortunately all the websites are not following the same standards.
The above brings up an important issue.
(i.e) soley depending on the HEAD method for checking the validity of the link may fail sometimes even if the link is
valid.
Please put up your comments and observations on this.
Sample Code
public static void main(String[] args) {
try{
URL myurl = new URL("http://calendar.google.com");
URLConnection connection = myurl.openConnection();
if(connection instanceof HttpURLConnection) {
HttpURLConnection httpConnection = (HttpURLConnection) connection;
HttpURLConnection.setFollowRedirects(true);
httpConnection.setRequestMethod("HEAD");
httpConnection.connect();
System.out.println("Response = "+httpConnection.getResponseCode());
catch(Exception e) {
System.out.println(e);

Basic webpage link checker

Hello all,
I am attempting to write a basic link checker to parse an html page and determine if any links are dead. I found a couple tutorials online, and am using one of them to test a webpage. However, i am running into multiple problems. The basic link checker verifies links by using the http HEAD request, it then checks the response code and determines from there if the link is dead.
However, I have two major problems with this:
1) How can I verify links when they are not using http, for instance a ftp link on a webpage?
2) Sometimes when I parse link, i am losing the protocol from the link....
ie. href="http://www.ibm.com/systems/x/=>href="//www.ibm.com/systems/x/"
             Reader rd = getReader(rootURI);
              // Parse the HTML.
              kit.read(rd, doc, 0);
              // Iterate through the elements
              // of the HTML document.
              ElementIterator it = new ElementIterator(doc);
              javax.swing.text.Element elem;
              System.out.println("Starting Validation from: " + rootURI);
              while ((elem = it.next()) != null) {
                SimpleAttributeSet s = (SimpleAttributeSet)elem.getAttributes().getAttribute(HTML.Tag.A);
                if (s != null) {
                  System.out.println("attributeSet: " + s);
                  String link = (String)s.getAttribute(HTML.Attribute.HREF);
                  System.out.println("Validating: " + link);
                  validateHref(link);
                }else{
                  //System.out.println("Attribute set is empty");
                  //flag this to user
              }This is the block of code i am using to extract the link from the html source. My console output looks like this:
[stdout]
attributeSet: href=//www.ibm.com/systems/x/ class=left-nav-overview
Validating: //www.ibm.com/systems/x/
[stdout]
However, looking at the html source, the link should be http protocol....ie. http://www.ibm.com/systems/x , since i later check to make sure that http protocal urls start with "http:", these links that do not have http: at the beginning are being ignored...
Can someone please help and explain to me how I can fix this? Also, i am eventually planning to turn this into more of a web spider, and traverse levels of pages checking and validating the links.
Thank you,
Nick

heres the full source. Let me know if theres anything else to make my questions more clear. Thanks!

Hello Yatsee,
We have seen some B1 documents in B1iSN via: Integration application explorer -> B1 Event monitor under tab "Filtered". It seens that the EventSender is working few seconds after the restart, and then, it goes down. From this moment on, we receive the exception shown above constantly (I guest every 3seconds that is the configuration time) and documents are trapped in table SEVT.
In order to see the error we run the service directly from the windows command console.
Im not sure but maybe the problem is due to the JAVA VIRTUAL MACHINE version.
Could you tell us how to check if this problem is due to some java stuff.
Regards,
Jose

Thanks

Your WriteImage servlet needs to read the image file in from wherever it is (hard drive, database, whatever), then write it back out to the browser. To do that, first use the HTTPServletResponse object to send the appropriate headers, then call the getOutputStream() method to get an output stream to write the data to. This data will be sent to the browser which, if you've set the headers correctly, will display it as an image.
It's been a long time since I did this (we abandoned storing images in databases quite a long time ago), so I can't be more specific than that, but hopefully that'll be enough to get you going. If you run into any problems, reply and I'll see if I can help further.

OBIEE and Mapviewer

I just read on the cook book of the OOW last november regarding using OBIEE with Mapviewer. However, I came to one part and I don't know what should put inside the file obiee_nsdp_xml_direct.jsp. Anybody have any idea how to do it? Or this file can be retrieve somewhere?
Thanks in advance =)

Sorry, should have included it in the workshop doc. Will be there this time.
Jerry Conrad wrote it. Hopefully he won't mind it being posted here.
Note its sample code and hence all the usual disclaimers apply.
Enclosing the code in CDATA.
