Re: sending from MIDlet, receiving in PHP on server

2009-09-28T10:53:32Z

Thanks for your answer :-)

About "encode":
In fact I thought this function should be defined in one of the classes which were included in the example. I made my code with the use of three source codes which I found in the internet:
1) http://developers.sun.com/mobility/midp/ttips/HTTPPost/ <- especially this one
2) http://www.java2s.com/Code/Java/J2ME/SampletodemonstrateHttpGETandPOSTfromMIDlet.htm
3) http://www.xyzws.com/Javafaq/how-to-use-httpurlconnection-post-data-to-web-server/139

About "multipart/form-data":
Now I understand the difference between "application/x-www-form-urlencoded" and "multipart/form-data" :-), thanks. It looks like in simple version I can use the default "application/x-www-form-urlencoded" and send string.
I guess what I have written previously should be OK: [code]sendTextFile("123456789012 234567890123 end");[/code] if there would be proper encoding, changing it to value=123456789012+234567890123+end. But what should I include to support proper encoding for x-www-form-urlencoded? I guess there is no need for me to implement this encode function because it should already be implemented somewhere.

And about array $_POST:
The crucial thing is that I don't have much experience with PHP :-(. I know there exists this table with all the values received by PHP on server. I guess there should be some code in PHP run on server but I don't know how to have this code to listen all the time for receiving POST messages and saving it to database or to text files in one given directory. I guess I should soon learn how to do it (I hope I would :-)).
On the other hand I've got terrible configuration of server (I'm not admin of this server) - there are already installed PHP, Apache, IIS, KeyFocus Web Server - some of those things do the same but I guess their ports are somehow redirected on the router. At this moment I need to decide - what to choose to receive data on server. At first I thought about PHP. (But: look at my new approach below). In order to do it, I guess I need to read the whole install.txt of PHP because it doesn't work properly.

About new approach:
http://codetrips.blogspot.com/2007/04/http-post-from-j2me-midlet.html <- If I've got Apache on my server (and other things mentioned above) - would it be good idea to install this Apache Tomcat JSP container?

Greetings :-)!

Hi johnyjj2,

Can I ask you in what class is defined the function "encode"? if it is defined by you, can you post the code?

About PHP, if you are going to send the data as a file, remember to add the "multipart/form-data" in the HTTP headers: http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4
Other way is if you send the data as the same way that with GET, that is att1=value1&att2=value2&...&attN=valueN, the PHP already parses it and your value will located at the array $_POST.

sending from MIDlet, receiving in PHP on server

2009-09-25T10:32:41Z

Hello :-)!

Summary: I'd like to send text file from MIDlet on mobile phone to PHP on server. There's problem with method encode(java.lang.String) in MIDlet. I can post code of MIDlet, if needed.

------- MIDlet ----------

I want to create MIDlet, which can send with the use of POST method and httpconnect little text file (or just string variable) to the server. The server would receive this file (or string) with the use of php.

Unfortunately, MIDlet doesn't compile in Wireless Toolkit 2.5.2_01 for CLDC. There is error about encode function, which changes string variable to the format allowed by httpconnection:

[quote]C:\Documents and Settings\MainAccount\j2mewtk\2.5.2\apps\myMidletSendData\src\myMidletSendData.java:90: cannot find symbol
symbol : method encode(java.lang.String)
location: class myMidletSendData
String encodedData = encode( rawData ); // user-supplied
^[/quote]

I guess it may be problem with includes. This is what I've got:
[code]import java.io.*;
import javax.microedition.io.*;
import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;[/code]

-------- PHP ------

The other question is about PHP. I've got book about PHP and example how to create file php which contains form responsible for sending file from computer in web navigator to server. I also have got code responsible for receiving this file (from directory where there are stored temporarily stored files received by the server).

In my case it is not web browser (like IE or MF) which sends the file, but MIlet. I guess it is not big difference because in both cases files received by server are stored in temporary folder. However I don't know how to know name of variable connected with the received file. In the case of sending from web browser to server this name is used both in php responsible for sending and receiving:
File in web browser: [code]Load this file:<input name="usersfile" type="file">[/code]
File to receive: [code]&usersfile = $HTTP_POST_FILES['usersfile']['tmp_name'];[/code]
In MIDlet: [code]HttpConnection conn = null;
String url = "http://87.205.xx.xx/datareceiver.php";[/code]
In the case of MIDlet sending it to server, I don't know how php on server should know name of this file.

Greetings :-)!

Re: How does the T80 and the microSD cell-idea

2009-09-13T19:57:57Z

Hello podo,

The microSD cards bring to the T80 the S/E and the Mifare internal tag. But, without the microSD, the T80 still can read external tags.

The microSD cards were built independently from the mobile. There are two extra pins than connects with the T80's NFC modem. So that, if the other mobiles also offer this kind of connection, the microSD should work for them too.

Best regards,

How does the T80 and the microSD cell-idea

2009-09-10T01:54:43Z

Hello, I ordered the Pro Pack with T80 and microSD cell-idea and I'm doing the first tests.
I would ask:
The BenQ T80 works in NFC only if you have inserted the microSD cell-idea?
The microSD cell-idea works only with phones already in place for NFC?
Thank you.

Reading MiFare SIM card

2009-08-13T10:21:19Z

Hi all,

I'm starting developing a small application that must read data from a MiFare SIM card. I've been following the examples in the T80 Programmer's Guide, as well as the tips that appear in this forum. However, calling pconn.transceive(input), where pconn is an InternalPlainTagConnection, does not return.

The code is very similar to that present in pages 7 to 9 in T80 Programmer's Guide. It includes some authentication code and reading code:

byte[][] authent_buffer = new byte[16][7];
// buffer containing the password for each block
for (int j = 0; j < 16; j++) {
// index of the
// block 0, 4, 8,12,...,60
authent_buffer[j][0] = (byte) (4 * j);
for (int u = 1; u < 7; u++) {
// default passwords
// are 0xFFFFFFFFFFFF
authent_buffer[j][u] = (byte) 0xFF;

}
}

int sector = 1;
try {
// authenticate the bloc
Vector input = new Vector();
input.addElement(new Integer(0/*MIFARE_AUTHENT_A_CMD*/));
input.addElement(authent_buffer[sector]);
log("."); // This is the last message I can see
Vector output = pconn.transceive(input);
log(".");

int block = 0;

input = new Vector();
input.addElement(new Integer(2)/*READ_COMMAND*/);

input.addElement(new byte[]{(byte) (4 * sector + block)});

logNewLine("Try to read Block " + (4 * sector + block));

// now do the reading
Vector out = pconn.transceive(input);

logNewLine("Read");

// print the ouptut of the reading
byte[] x = (byte[]) out.elementAt(0);

// Management of the element just read:
....

} catch (ContactlessException ce) {
// Handle exception
logNewLine("Exception while reading data: " + ce.getMessage());
} catch (IOException ioe) {
logNewLine("I/O Exception: " + ioe.getMessage());
}

As you can see, I'm trying to read sector 1, block 0.

There are some points I'd like to clarify:

- If I want to read from SIM card, must I open connector like this: pconn = (InternalPlainTagConnection) Connector.open("nfc:InternalPlainTag")?
- Are values 0 and 2 correct for commands authenticate and read?
- Is 0xFF the password for reading? I've seen in another post something about D3F7D3F7D3F7.

Thanks in advance.

Conditionally Setting Zend_Form_Element_Submit

2009-07-02T16:25:13Z

Hi,

I have been struggling with this today and thought someone might have some insights.

I have a form that I have built using Zend_Form. The form can be used to add or edit a record but I need to change the label of the Zend_Form_Element_Submit button depending on which of the two it is. So either "Add Record" or "Edit Record". I have tried setting passing a variable to the form but I get a warning that I can't overload the form. I have also tried setting a variable in the parent view and then referencing it from the form but that didn't work.

I am sure the answer to this is easy but for some reason the routes I have tried are not working.

Any suggesting?

In the form I was hoping to do the following

// form code
.
.
.

if ($actionName = "add") {
$submitLabel = "Add Record";
} else {
$submitLabel = "Edit Record";
}

$submit = new Zend_Form_Element_Submit('submit');
$submit->setAttrib('id', 'submitbutton')
->setLabel($submitLabel);

Thanks for the help,

Kenneth

Hi again,

after all the tests it seems that if we do not sign the midle with a verisign certificate, it will not work

so could you please ask ben q for either a "developer certificate" or a firmware version when the user could give (or not) permisissions

Advice needed for developer package for NFC / T80

2009-04-02T00:29:58Z

Hello:

We’re an IT business interested in doing some proof-of-concept work with NFC-integrated mobile phones and Cryptographic MicroSD cards. T80 phone looks very promising, and we’d like to ask a couple of questions about it:

1) In your commercial offers, you talk about “secure microSD cards” included in the T80 mobile packages. What kind of microSD cards are those? We’re particularly interested in knowing if they have cryptographic features (digital certificate storage, signature and verification of data).

2) As a developer, I’d like to interact with the NFC, do I need the “Pack Pro” package (includes doc + libraries) or would I be able to do so with the “Pack Mini” offer?

3) Does the NFC interface reside in the provided microSD cards? If they don’t have cryptographic features, we’d like to use some crypto microSD of our own with the T80, provided we can interact with our own crypto microSD’s and the NFC interface at the same time. This wouldn’t be a problem if your own cards have cryptographic features, of course.

4) What is the estimated delivery time to Europe?

Best regards,

Problem Connecting with Device via SPP with fixed baud rate

2009-03-04T07:32:24Z

Hi all,

I am writing a Java program on my Nokia 6300 cell phone to get access to data
stored inside a device via bluetooth serial port profile. The device is acting as a slave
in the communication process with fixed serial port settings of 9600,N,8,1.

Normally, the device should reply after receiving a command sent to it but on my cell phone,
I have to send the same command many times in order to get a single reply from the device.

I am wondering if the device is trying to tune the baud rate setting so that it can correctly
decode data bits sent from my cell phone. Does anyone know how to solve this problem? Or is there
any procedures that my program can make to make my cell phone sending data with the same settings
of the device?

Thanks,

Brian

BenQ T80 Certificate problem.

2009-02-03T07:54:54Z

Hello,

I have a problem with my recently bought T80.
I'm trying to develop applications with Visual Studio 2005/2008 but I'm getting an error when I try to debug or deploy them from the Visual Studio.
The error that I'm receiving is the next one:
"Error 1 :The device security configuration disallowed the connection. Ensure that you have the appropriate certificates on your device for development. Review your SDK documentation for proper security settings for connecting to this device. Device Connectivity Component".
It seems to be a certificate problem, so how can I get the certificate or dissable the security of my device in order to be able to deploy or debug my applications?

Thanks in advance,
Xabier.

Re: InternalPlainTagConnection

2009-01-15T01:04:22Z

Hi Joris,

Yes, that SecurityException is because your MIDlet must be signed. Permits also goes in the JAD file. What is the compiler that are you using for J2ME? I am using the Sun Wireless Toolkit.

Greetings,

Re: T80 don't seem to respond to any tag

2009-01-15T00:42:11Z

So if you have not been able to access to the secure element inside of the mobile through the contactless card reader, we should need to check the unit to replace it or repair it. Let me check with the responsible this issue and we are going to put in contact with you to watch the best way to solve it.

Sorry for the inconvenience,

Re: InternalPlainTagConnection

2009-01-15T00:12:45Z

I tried both.. The error I receive is:

java.lang.SecurityException: javax.microedition.io.Connector.nfc was denied

How can I give permission to the midlet to use io.Connector.nfc?
I am using WTK with the modified DefaultColorPhone to compile.

Do I need the midlet to be signed to be able to give permissions?

I tested with Inside contactless card reader with a SD card inside. Nothing happens.

I'm using their Accesso reader which can only reads ISO14443a/b, 15693 and sony protocols.

Re: T80 don't seem to respond to any tag

2009-01-14T22:59:03Z

Hi Jose

Thanks for your untiring efforts in answering me. Most of the tags I got are of iso14443-a std. What are stds that works with T80?

The tags I have got and tested with T80 so far are:
1) IC: NXP MiFare Ultra Light
Standard: ISO14443-A

2) IC: NXP MiFare Standard 1K
Standard: ISO14443-a

3)IC: Philips MiFare Ultra Light
Std: ISO14443-a

4) Std: ISO15693

Re: T80 don't seem to respond to any tag

2009-01-14T19:57:12Z

Hi noscon,

We have tested Ultra Light, 1k and 4K, and all them works with the T80s we have at office.

One question more, to check if the antenna works: if you plug the Cell-Idea's microSD in the mobile, and you put the mobile over a contactless card reader, is it able to read the secure element?

Re: InternalPlainTagConnection

2009-01-14T17:25:25Z

Hi Joris,

This is an strange problem. Reviewing the standard JSR257, there is not InternalPlainTagConnection class, maybe you should use the class PlainTagConnection. After of all, it will be the same, that InternalPlainTagConnection will implement PlainTagConnection interface. Can you test if it works now?

Best regards,

InternalPlainTagConnection

2009-01-14T17:22:49Z

Hi everybody,

I have received an email asking this question:

Hi Josergc,

I'm trying to read the internal tag, but when I implement the function "pconn = (InternalPlainTagConnection)Connector.open("nfc:InternalPlainTag");" in the midlet, the midlet won't execute on the t80...

I don't get any errors; I don't even call the function directly at startup of the midlet.
Could this be due to the signing of the midlet (which I didn't)? If so: is there a way to read the Internal Tag without signing or is there a public key that can be used? (without registering on VeriSign)

regards,

Joris Suilen
