netbeans 7.4 maven javafx project doesn't run

Executing a javafx/maven project in netbeans doesn't work. The fix is here:

https://netbeans.org/bugzilla/show_bug.cgi?id=233613

It involves changing the following two step:
Step 1: Add the following to the projects pom.xml file:

<execution>
    <id>default-cli</id>
    <goals>
        <goal>exec</goal>                            
    </goals>
    <configuration>
        <executable>java</executable>
        <commandlineArgs>${runfx.args}</commandlineArgs>
    </configuration>
</execution>

Analysing USB traffic with USBPcap and wireshark

In order to trouble should the concept 2 CSafe libraries I needed to see the bytes traveling across the wire on the USB bus. To do this I, I used USBPcap.

The need to look at the bytes being sent over the USB bus became necessary when I was working with the CSafe libraries from concept2.

The USBPcap programm can be download here:

http://desowin.org/usbpcap/index.html

(Watch the installation. If you change the default directory and don't watchout it won't add back a application directory for itself. When you try to deinstall it, it will delete the whole directory!)

The USBPcapCMD application runs as a command line programm. One of the things it will ask you for is a output file name. If you name this with a ".pcap" extension and you've installed wireshark (Version 1.10.5), you'll be able to open the file with wireshark and look at very comfortably. 

concept2 + PM + SDK

Concept2 SDK

The SDK libraries from concept 2 should allow one to write 3rd party application for the rower. I've managed to create a prototype, which uses a javafx control (jfxtra control), a shim library written in C using Visual C++ 2010 Express and the libraries delivered with the SDK. See (https://www.youtube.com/watch?v=9wshu_TufRs)

The documentation for the SDK I've store here.

Programming the original prototype as described above was not a problem; however, when I tried to improve parts of it I ran into troubles. One of these was the ability to bundle PM commands together as I've described here in the online forum from concept2 (http://www.c2forum.com/viewtopic.php?f=15&t=16490)

bundling commands with 

CSAFE_SETUSERCFG1_CMD for PM4

Hello,

I’m trying to use the CSAFE_SETUSERCFG1_CMD with the tkcmdsetCSAFE_command function as a wrapper for three other PM commands; namely: CSAFE_GETHORIZONTAL_CMD, CSAFE_GETCADENCE_CMD and CSAFE_GETPACE_CMD; but have not been successful. My call to the above CSAFE method returns without any error but I never get any results back. 

I’ve had no problems calling the commands individually (see here: https://www.youtube.com/watch?v=9wshu_TufRs) but now I would like to bundle them together for efficiency reasons.

I got the idea to do so from the documentation: “Command Example #2 – Get PM3Worktime and Get PM3Workdistance Command” but now believe that I may have misunderstood something.

My code without the initialization looks as follows:

/----------------------------------------------------------------------------------------------/
void pollpm4()
{
UINT16_T unit_address = 0;
UINT16_T cmd_data_size = 0;
UINT32_T cmd_data[64] = {0x00};
UINT16_T rsp_data_size = 100;
UINT32_T rsp_data[64] = {0x00};
ERRCODE_T ecode;
unit_address = 0;

cmd_data[0] = (UINT32_T) 0x1A;
cmd_data[1] = (UINT32_T) 3;
cmd_data[2] = (UINT32_T) 0xA1; //CSAFE_GETHORIZONTAL_CMD
cmd_data[3] = (UINT32_T) 0xA7; //CSAFE_GETCADENCE_CMD
cmd_data[4] = (UINT32_T) 0xA6; //CSAFE_GETPACE_CMD 0xA6
cmd_data_size = 5;

int cnt = 1;
while(1){

rsp_data_size = 100;
memset(rsp_data, 0x00, sizeof(rsp_data));

ecode = tkcmdsetCSAFE_command(unit_address, cmd_data_size, cmd_data, &rsp_data_size, rsp_data);
printf("%04d -> %d %d : %X %u : %X %u %u %u : %X %u %u %u : %X %u %u %u \n",
cnt, ecode, rsp_data_size,
rsp_data[0], rsp_data[1],
rsp_data[2], rsp_data[3], rsp_data[4], rsp_data[5],
rsp_data[6], rsp_data[7], rsp_data[8], rsp_data[9],
rsp_data[10], rsp_data[11], rsp_data[12], rsp_data[13]);

cnt++;
if(ecode){
printError(ecode);
}

//
Sleep(500);
}
}
/----------------------------------------------------------------------------------------------/

And the output as follows:

intialization successful
COMMAND_DISCOVER successful: message is: PM's discovered: 1
COMMAND_GET_SERIAL_NUM successful: message is: 4XXXXXXXX
COMMAND_INIT_PROTOCOL successful: message is:
0001 -> 0 2 : 1A 0 : 0 0 0 0 : 0 0 0 0 : 0 0 0 0
0002 -> 0 2 : 1A 0 : 0 0 0 0 : 0 0 0 0 : 0 0 0 0
0003 -> 0 2 : 1A 0 : 0 0 0 0 : 0 0 0 0 : 0 0 0 0
0004 -> 0 2 : 1A 0 : 0 0 0 0 : 0 0 0 0 : 0 0 0 0
0005 -> 0 2 : 1A 0 : 0 0 0 0 : 0 0 0 0 : 0 0 0 0

Many thanks for your help,

Ok, maybe I’ve found it. It seems as if I should be using the CSAFE_GETPMDATA_CMD as a command wrapper instead of the CSAFE_SETUSERCFG1_CMD; however, this is a proprietary command, which requires “authentication”. Can someone tell me what is meant by authentication is this case?

In the SDK documentation, I found the following: These commands are not accessible via the “public” interface and require special “authentication” with the PM3/PM4 to function.

/-----------------------------my 2nd reply--------------------------------------------------/
 downloaded the code for the “Concept2 Watt Challenge” and built is using the libraries supplied with the code and it worked. The application bundles the PM commands together exactly as I would like to. 

I then rebuilt the application to run with the “newer” libraries from the SDK and it didn't work anymore. I get a checksum error:
C2Erg::PollThread->Error (-161): TKFRAME_CSAFE_FRAME_CHKSM_ERR CSAFE frame checksum error.

I realize that I had to change some minor things in the application in oder for it to work with the new libraries but I don’t think my changes have anything to do with the above error.
On the wire they every thing looks fine: 
Request:
f0:fd:00:1a:03:a3:a6:b4:a8:f2:00:00:00:3a:f2
Reply:
f0:00:fd:01:1a:07:a3:05:00:00:00:00:00:ba:f2

So I don’t understand the error message.

I guess I could use the libraries provided with the Watt Challenge application rather than those with the SDK but that wouldn’t be so nice.

Recompiling it involved down loading Qt building it and then creating a VC++ project that would be with it. This required creating the following batch file:

set QTDIR=C:\Programms\Qt\4.8.4
set PATH=%PATH%;%QTDIR%\bin
set QMAKESPEC=win32-msvc2010
qmake your_qmake_proj.pro
pause

The  your_qmake_proj.pro file was like this ( of course the name should have been something other than your_qmake_proj.pro):

 TEMPLATE = vcapp
 DESTDIR  = C:/Projekte/concept2/workspace/devstudio/c2watt
 HEADERS += C2Logger.h
 HEADERS += c2watt.h
 //all header files here...
 HEADERS += wattmeter.h
 SOURCES += C2Logger.cpp
 SOURCES += c2watt.cpp
//all source files here ...
 SOURCES += WattMeter.cpp
 DEFINES += QT_DLL
 CONFIG  += qt warn_on release

After running the above batch, I had a VC++ project, which I could open and build. Of course, I had to add in the libraries path and what not.

CVS, Eclipse and plink (putty)

CVS (1.12.13), Eclipse (Version: Juno Service Release 1), SunOS (5.10)  and plink (putty Release 0.63)

Sometimes getting Eclipse to work with CVS can be difficult. It took me a long time, but eventually I found a solution, which surprisingly worked. Basically, I set up plink to use ssh public key authentication authentication. I stored the public key in the authorized key file on the cvs server in my user's home directory: ~/.ssh folder.

The step were as follows:

First putty's puttygen utility was used to generate a key pair. In my case, I used a SSH2-DSA 2048 key, which looked as follows:

Then he contents from the textfield with the label "Public key for pasting into OpenSSH authorized_keys file:" were copied into the authorized_keys file in the ~/.ssh directory of the unix user who was used to access the CVS repository. The contents of the authorized_keys file looked like this:

In eclipse, the "Ext Connection Method" was configured as follows:

Notice that the "-i" parameter, which points to the file containing the private key generated above using puttygen. Here, in this example, the private key was NOT protected with a password when it was saved from puttygen; probably not a good idea.

Now in Eclipse, set up a CVS repository as follows:

Notice that the connection type is "ext" and that the user  and password are set. In my case, the password had no affect because I was using public key authentication and because my private key was not protected with a password. It could be that the password here might be used to access the private key, but I'm not really sure about it and didn't test it.

Another factor which might have an affect on the functioning of the above configuration and which has not be investigated because of time constraints is:

In the initialisation file of the unix user with which CVS was accessed, I set the path to the CVS client and added it to the working PATH as following:

export CVS_HOME=/opt/sfw/bin

export CVS_SERVER=${CVS_HOME}/cvs

export PATH=$PATH:$CVS_HOME

echo "CVS_SERVER=${CVS_SERVER}"

javafx ensemble with netbeans

When running the javafx (javafx-samples-2.2.45) Ensemble example on Windows with netbeans, it is possible that the following error with occur:

Your active platform is: default_platform, but the corresponding property "platforms.default_platform.home" is not found in the project's properties files. 

 Either open the project in the IDE and setup the Platform with the same name or add it manually.

 For example like this:

     ant -Duser.properties.file=<path_to_property_file> jar (where you put the property "platforms.default_platform.home" in a .properties file)

  or ant -Dplatforms.default_platform.home=<path_to_JDK_home> jar (where no properties file is used)

To fix this, open the project.properties file in the nbproject subfolder of Ensemble project, which is contained in the above samples zip file.

native.bundling.enabled=false
platform.active=default_platform
platforms.default_platform.home=C:\\Program Files\\Java\\jdk1.7.0_25

Of course, the values will depend on  the location of your java installation.
