errors compiling demo codes

[dev_d_bhatt]

Dear Friends,

I have tried without success to compile the codes available on this page:
http://wiki.forum.nokia.com/index.ph..._%28NFC%29_tag

I'm using Sun Java Wireless Toolkit, and prior to this example i managed to compile another piece of code from another site, so i believe i have it set up correctly.

I get this error message when compiling:

C:\WTK2.5.1\apps\ReadSerial\src\ReadSerial.java:1: package javax.microedition.contactless does not exist
import javax.microedition.contactless.ContactlessException;
^
C:\WTK2.5.1\apps\ReadSerial\src\ReadSerial.java:2: package javax.microedition.contactless does not exist
import javax.microedition.contactless.DiscoveryManager;
^
C:\WTK2.5.1\apps\ReadSerial\src\ReadSerial.java:3: package javax.microedition.contactless does not exist
import javax.microedition.contactless.TargetListener;

.......... an so on

I'm a bit surprised this message pops up, since i've installed the
toolkit, doesnt it mean that the packages should have been correctly
configured as well?

Any help will be appreciated!!

Hi,
just for more info,

I managed to compile this code
http://developers.sun.com/mobility/m...lloMIDlet.java

Which also imports javax.microedition

So i guess its the javax.microedition.contactless that is giving the problem...

[dev_d_bhatt]

after doing some more research, i beleive that even tho i have installed the Nokia 6131 NFC SDK, the contactless APIs are still not recognized/showing up.. i believe this to be the issue... is there any way to rectify?

Hi,

It seems that you have not used the Nokia 6131 NFC SDK to build your midlet. As current WTK does not support JSR-257 you cannot compile the NFC midlet using WTK alone.

You did not say how are you compiling your sources, but if you are using the graphical UI of Wireless Toolkit you must select Nokia 6131 NFC SDK from the "Device:" -dropdown box. After that WTK uses libraries of our SDK to compile the midlet.


In case it is not available in dropdown, you have to copy the whole Nokia 6131 NFC SDK directory (by default C:\Nokia\Devices\Nokia_6131_NFC_SDK_1_1) under \wtklib\devices in your WTK installation directory.

Hope this helps.

hi, as a matter of fact, i am using WTK to compile the codes.
I tried copying the folder into my WTK directory and now i can see it there, but when i compile, the same errors appear although the emulator being used now is the Nokia 6131 emulator..

is there any other tool or ide i should use to compile my codes? i'm at my wits end.......

Hi, i managed to make it build successfully by choosing the Nokia 6131 NFC SDK as the default device, now build is successful, but there are some other errors when trying to run

1st error

Emulator: Missing JAR file.
Emulator command: C:\WTK2.5.1\wtklib\devices\Nokia_6131_NFC_SDK_1_0\bin\emulator.exe -Xdescriptor "C:\WTK2.5.1\apps\ReadSerial\bin\ReadSerial.jad"
Emulator: Missing JAR file.
Emulator command: C:\WTK2.5.1\wtklib\devices\Nokia_6131_NFC_SDK_1_0\bin\midp.exe -Xdescriptor "C:\WTK2.5.1\apps\ReadSerial\bin\ReadSerial.jad"

I guess this is because i didnt create the JAR/JAD files, so i selected Project-->Package-->Create package to create the necessary files and i tried to run again, this time i got this error:

Build complete
WARNING: Attribute value for MicroEdition-Profile defined in JAR manifest is not supported.
Emulator command: C:\WTK2.5.1\wtklib\devices\Nokia_6131_NFC_SDK_1_0\bin\emulator.exe -Xdescriptor "C:\WTK2.5.1\apps\ReadSerial\bin\ReadSerial.jad"

Any ideas how to solve thiS?

[dev_d_bhatt]

Solved!!
apparently in the JAR & MF (manifest) files,
the MIDP version was 2.1

i just manually changed to 2.0 and it works lol

[pavan.kumar]

Hi,how did you change the MIDP version in JAR files?...i comes with the encrypted letters..
Any help please?

[esunilkumare]

hi pavan,

open the associated JAD file and change the parameter MicroEdition-Profile: MIDP-2.0 according to your need.

you cant change the MIDP vesrion in JAR files.

hope this helps

Dear all,

You can also try to run it with the 6212_NFC_SDK platform and with MIDP 2.0
And adding the following optional packages:
Contactless Communication API 1.0
File Connection and PIM Optional Packages 1.0
JSR-257 API Extensions 1.0

Hope it helps.
