JMS1.1 Domain Unification sample using OC4J 10g

I am trying to run the JMS1.1 Domain Unification sample using OC4J 10g
I am not sure why I get the Invalid provider URL exception at run time when trying to run AsyncClient using listenTopic in Ant. The code prints out the provider URL accurately from my ConnectionParam.java file but exception happens after that. I am running the J2EE container using OC4J and can access http://localhost:8888/adminoc4j as an admin user.
++++++++++++++++++++++++++++++++
C:\JMS1.1>c:\apache-ant-1.6.1\bin\ant listenTopic
Buildfile: build.xml
listenTopic:
[java] local url...
[java] http://localhost:8888/adminoc4j
[java] env Hashtable populated...
[java] javax.naming.NamingException: Invalid provider URL
[java] at com.evermind.server.rmi.RMILocation.parseURL(RMILocation.java
:83)
++++++++++++++++++++++++++
This is the initialize method from AsyncClient.java.

public void initialize() throws Exception{
Hashtable env = new Hashtable();
// set the environment properties
env.put(Context.INITIAL_CONTEXT_FACTORY,
     "com.evermind.server.rmi.RMIInitialContextFactory");
System.out.println("local url...");
System.out.println(ConnectionParams.PROVIDER_URL);
env.put(Context.PROVIDER_URL, ConnectionParams.PROVIDER_URL);
env.put(Context.SECURITY_PRINCIPAL, ConnectionParams.USERNAME);
env.put(Context.SECURITY_CREDENTIALS, ConnectionParams.PASSWORD);
     System.out.println("env Hashtable populated...");
// get the initial context
InitialContext ctx = new InitialContext(env);
     System.out.println("got context...");
// lookup the queue and topic objects
Destination topic = (Destination) ctx.lookup("jms/sampleTopic");
     System.out.println("looked up topic...");
// lookup a connection factory
ConnectionFactory factory = (ConnectionFactory) ctx.lookup("jms/sampleConnectionFactory");
// create a connection
Connection connection = factory.createConnection();

Sorted out the answer myself.
+++++++++++++++++++++++++++++
The URL in ConnectionParams should use ormi protocol as given in the sample example.
Good example and it all works! Thanks.

Any code samples using StringWriter?

I looked through the examples here and couldn't find one that used StringWriter. Does anyone know where a code sample using it can be found?
Thanks

OK... I got a small sample program to work but I am having trouble getting this one to work with StringWriter. I get an error on the line containing ---- s = new String(sw.toString); It says it can't resolve symbol. Here is the part of the code that is giving me trouble.
try {
               fin = new FileInputStream(args[0]);
          } catch (FileNotFoundException e) {
               System.out.println("File not Found");
               return;
          } catch (ArrayIndexOutOfBoundsException e) {
               System.out.println("Usage: ShowFile File");
               return;
          do {
               i = fin.read();
               if (i != -1) {
                    pw.print(i);
          } while(i != -1);
          fin.close();
          s = new String(sw.toString);
          StringTokenizer st = new StringTokenizer(s);     (I didn't put the import statements, variable declarations or main line for clarity). I also tried putting sw as the argument for StringTokenizer() as well and it didn' work.
Any help would be great.

Code sample using Oracle Provider

Hi Is any got code sample using Oracle Provider with aspnet app

Assuming your stored procedure is returning a REF CURSOR, it cannot be done. Oracle's REF CURSORS are read only constructs.

It's strange bacause DTD is available under given address.

Do you have any other tld file, which uses the same DTD version? Do tags define in it work properly?

Multirate sampling using CLK IN with PXIe-5922

Hi
I am working in an application where I need to change the sampling rate of an acquisition between 500 ks and 5 Ms without stopping the acquisition. The idea is to be acquiring continuously and be able to change the sampling frequency live depending on external events
I was thinking about doing this using a PXIe-5922 and controlling its sampling frequency using the external sample clock input (maybe I would have to change the decimation factor by software as well?) connected to a signal generator (5404?) or some other clock generator whose frequency I can change without stopping the signal (maybe some specific development on PXI-7833R). My concerns are:
Reading the 5922 spes I am not sure if I can change its sampling frequency between those values (500 kHz and 5 Mhz) using the external sample clock input without stopping the acquisition (my experience with other DAQ is that when you have to do any programming of the instrument the acquisition stops during the programming phase)
If the above can be done, I guess my second problem will be to determine in the acquired data where a change of the sampling frequency has happened (as the driver will not know if I am using an external clock)… but I am not yet much worried because of this J
I have not buy the hardware yet until I am sure I am in the right way... so any help will be much appreciated
Best regards
Guillermo

Guillermo,
Keep in mind the Reference Clock is used to generate the internal Sample Clock. Changing the frequency of the Reference Clock will result in the same Sample Clock frequency. Also, changing the Reference Clock frequency should not be done while acquiring since the device's clock circuitry needs to be configured based on the Reference Clock frequency. I don't think this solution will produce desirable results for these reasons. Unfortunately, the 5922 does not accept an external Sample clock from the Clock In terminal since the Sample Clock needs to be extremely high quality to meet the device's specifications.
Do you really need to run continuously across different sampling rates, or could you afford a small amount of reconfiguration time between frequencies? If you can, then you can also avoid the additional complication of not knowing where in your acquisition the sampling rate changed. Could your application run continuously, then reconfigure the sampling rate when a trigger is received?

Biztalk WCF-SQL polling sample using a FOR XML Path

I've been searching in the web for a sample that uses FOR XML "PATH" to poll the SQL database . The result returned from my query is a parent child data and FOR XML PATH is the best choice to structure it in that way . I guess I'm missing something while
generating the schemas from this stored procedure.
I guess Dan Rosanova has touched on this concept (http://social.technet.microsoft.com/wiki/contents/articles/3480.aspx)
, but its using XML Auto. Again there is no sample available so makes things a bit difficult.
Can someone point to a sample walkthrough , generating the schemas and then later using it in the application.
Thanks
Anthstone

I used XMLPolling and it worked for me. you can go for XMLPolling. Steps to be followed:
1) Create the SP which will have the SELECT query similar to below:
;WITH XMLNAMESPACES (default 'http://yourcustomnamespace')
Select * from Employee FOR XML PATH('YourCustomRootNode')
2) Create a schema out of the table using the following query
Select * from Employee for
xml
auto,
xmlschema
3) Re-name the root name and namespace as per you mentioned in point#1 (YourCustomRootNode)
4) Create an Envelope Schema and refer the schema from point#3. Also make a note of the root node name and namespace that we need to specify
in the admin console.
5) Assign the Body XPath to debatch. Refer
this. Deploy the solution.
6) In the Admin console, add the Root Node Name and namespace mentioned in point#4 under "XmlStoredProcedureRoodNodeName" and "XmlStoredProcedureRoodNodeNamespace"
There you go. I did this for debatching. You can do for nomarl batch message instead of Envelope create a normal document schema.
Thanks

How can I program my imager to take longer samples using labVIEW?

What I would like to be able to do is to use LabVIEW to program my external hardware to take a sample length of a specific time. I would also like to be able to find out how fast my Imager is sampling at, kind of like using the program as an oscilliscope to read the sampling rate of my hardware.
Any advice would be much appreciated.
Thanks,
Brian

Bruce,
I have a PCI-1424 Image Aquisition board, and it is connected to a KLI-2113 Kodak imager. The reason that I was thinking that I could get some kind of clock reading from the Kodak imager is that In the graphs, (I will send them), in some of them you can definatly see a pattern, exspecially if you leave the points on the chart and run another cycle, they almost mimick the previous results. What I would like to be able to do is to see how long each one of those cycles are running. The graphs time axises are messed up because If I have it one way I get like 295 and if I transpose it I get 79, (as you can see in the graphs). I think those are how many samples that are comming from the board but in some instances you can see th
e exponential grades on the graphs and charts which leads me to believe that somehow the CCD chip is reading the collected charge in samples starting from the left to the right, (or the other way). I want to know how it is reading it, how long each sample is and how to collect either x amount of samples or y amount of time for each sample. Also it is interesting to note that the sampling on the x axis stay the same no matter where and how the light is shown onto the CCD chip.
Anyways, I will attach the graphs so you can see what I mean and I will also attach the KLI-2113 Manual. I really appreciate your help Bruce,
Brian

Problem with meal order sdk sample (using c++ to define business logic)

Hi there,
I'm trying to use meal order udo sample from sdk but i cannot register .dll extension. it gives me Invalid dll path or name [User-Defined Object - Extension Name] error.
What am i doing wrong?
Thanks in advance

Thanks but I was asking about something else. Maybe I wasn't precise.
I'm trying to develop udo as extension written in c+. There is such a possibility. You can compile it into dll and then upon creating new object from sap b1 ui you link to that dll. Again this is written in c+ not c# or vb. But when I link that dll I get errror message that I posted in my previous message.
Again I'm talking about this way to build udo objects -
UDO - DLL (1)
Thanks in advance

Determine Physical Samples using a Sample Scheme

Dear QM friends,
currently I am struggling with a QM issue that maybe you can help me with.
Within the one of our factory sites we have rolled-out QM for quality inspection at GR, for this we use Physical Samples (just like we do in other factory sites). Only thing is that in this specific site they want to draw their physical samples based on a sample scheme. The other site use formulas to draw samples.
So we have setup a sample-drawing procedure to determine the samples based on a specific sample scheme that has been setup for this factory.
What I expected SAP to do when doing a goods receipt of for example 3 items is that SAP will draw 3 Physical Samples with a quantity of 1. However strangely SAP creates 1 Physical Sample with a size of 3 items.
With kind regards,
Kenny Galle

Thanks for both of your responses
In relation to you questions I checked the following:
1. I am using Primary Samples alone and they are to be taken from a Sample Scheme linked in the Sample-Drawing Procedure;
2. Increasing the sampel size does not work, I am still left with one physical sample and multiple items. Where I want a physical sample PER item.
When we use a formula in the Sample-Drawing procedure (e.g., "P1" or "TRUNC(P1/10)+1") it works fine and we get a Physical Sample per serialize item.
Any guidance will be highly appreciated!

Where can I find the 'club' database sample used in the 'Information Design Tool' tutorials?

Hi experts!
I have been studying the tutorials for the Information Design Tool (http://scn.sap.com/docs/DOC-8461) and in some of them they use a database called 'club'. For what I see, this is an Access 2007 database and has some tables called City, Region, Customer, etc. I have been searching it across the web and have not found it.
Hope somebody knows where I can find this sample.
Thanks in advance!

Hi Julio,
You should be able find it in following locations
If you are on 64 Bit OS
C:\Program Files (x86)\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\Samples\webi

Converting audio samples using libav*

Hello guys,
I've been looking for a solution for several days by now and have not gotten any smarter, I hope that someone of you is able to help me
What I'm currently working on is an application able to generate audio fingerprints (specifically acoustID fingerprints). To do so, I started with the sample
code that demonstrates the basic fingerprinting capability. You can find it here.
It is part of a library called chromaprint.
As you will see, a lot of this code uses deprecated functions. As a newbie to sound conversion, the sense of a lot of the calculations in the file is oblivious to me
Still, I want to renew the code to use functions that are up-to-date. Ideally I'd understand the code more thorough then, or so I thought.
I started modifiying the decode_audio_file function from fpcalc.c and got until here, where I am now stuck:
int decode_audio_file(ChromaprintContext *chromaprint_ctx, int16_t *buffer1, int16_t *buffer2, const char *file_name, int max_length, int *duration)
AVFormatContext *format_ctx = NULL;
AVCodecContext *codec_ctx = NULL;
AVAudioConvert *convert_ctx = NULL;
AVStream *stream = NULL;
AVCodec *codec = NULL;
AVPacket avpacket;
AVFrame *decoded_frame = NULL;
FILE *f;
int frameFinished = 0;
int stream_id, ok = 0;
int buffersize = AVCODEC_MAX_AUDIO_FRAME_SIZE + FF_INPUT_BUFFER_PADDING_SIZE;
uint8_t inbuf[buffersize];
/* initialize data packet that is read from the stream */
av_init_packet(&avpacket);
avpacket.data = inbuf;
avpacket.size = buffersize;
/* make space for frame that contains decoded data */
decoded_frame = avcodec_alloc_frame();
/* tell format_ctx about the input */
if (avformat_open_input(&format_ctx, file_name, NULL, NULL) < 0) {
fprintf(stderr,"ERROR: couldn't open the file");
goto done;
if (avformat_find_stream_info(format_ctx, 0) < 0) {
fprintf(stderr,"ERROR: couldn't find stream information in the file");
goto done;
for (int i = 0; i < format_ctx->nb_streams; ++i) {
codec_ctx = format_ctx->streams[i]->codec;
if (codec_ctx && codec_ctx->codec_type == AVMEDIA_TYPE_AUDIO) {
stream = format_ctx->streams[i];
break;
if (!stream) {
fprintf(stderr,"ERROR: couldn't find any audio stream in the file\n");
goto done;
codec = avcodec_find_decoder(codec_ctx->codec_id);
/* chromaprint expects signed 16 bit samples */
codec_ctx->request_sample_fmt = AV_SAMPLE_FMT_S16;
if (codec_ctx->sample_fmt != AV_SAMPLE_FMT_S16) {
convert_ctx = av_audio_convert_alloc(AV_SAMPLE_FMT_S16, codec_ctx->channels,
codec_ctx->sample_fmt, codec_ctx->channels, NULL, 0);
if (!convert_ctx) {
fprintf(stderr, "ERROR: couldn't create sample format converter");
goto done;
if (!codec) {
fprintf(stderr,"ERROR: unknown codec");
goto done;
if (avcodec_open2(codec_ctx, codec, NULL) < 0) {
fprintf(stderr,"Could not open codec\n");
goto done;
chromaprint_start(chromaprint_ctx, codec_ctx->sample_rate, codec_ctx->channels);
*duration = stream->time_base.num * stream->duration / stream->time_base.den;
int len;
while (av_read_frame(format_ctx, &avpacket)>=0) {
if (avpacket.stream_index == stream->id) {
len = avcodec_decode_audio4(codec_ctx, decoded_frame, &frameFinished, &avpacket);
if(frameFinished) {
int data_size = av_samples_get_buffer_size(NULL, codec_ctx->channels,
decoded_frame->nb_samples,
codec_ctx->sample_fmt, 1);
if (convert_ctx) {
const void *ibuf[6] = { decoded_frame->data };
void *obuf[6] = { buffer2 };
int istride[6] = { av_get_bytes_per_sample(codec_ctx->sample_fmt) };
int ostride[6] = { 2 };
len = data_size / istride[0];
if (av_audio_convert(convert_ctx, obuf, ostride, ibuf, istride, 4) < 0) {
fprintf(stderr,"WARNING: unable to convert %d samples\n", len);
break;
if (!chromaprint_feed(chromaprint_ctx, buffer2, decoded_frame->nb_samples/2 )) {
fprintf(stderr,"ERROR: fingerprint calculation failed\n");
goto done;
} else if (!chromaprint_feed(chromaprint_ctx, decoded_frame->extended_data, decoded_frame->nb_samples)) {
fprintf(stderr,"ERROR: fingerprint calculation failed\n");
goto done;
ok = 1;
done:
avformat_close_input(&format_ctx);
avcodec_free_frame(&decoded_frame);
return ok;
You can find the documentation for the used chromaprint functions here.
As I said, I am not really sure whether I have understood all of what is going on in the unmodified version of the function, so please bear with me
Any answers or suggestions for reading material will be gladly appreciated!
PS: goto marks will be removed once the code works

First slice the track using the Strip Silence function (in L9 you could also use Flex mode to splice the track), then convert all the resulting regions into new Audio files using the copy/convert function. Then drag all those files into the EXS (hit the edit button first) using the contiguous mapping feature, set the lowest note to C0 or wherever you want the mapping to start.

Simultaneous Sampling using a DAQ BNC2110

Hey folks,
So I'm trying to take data from two different photo diodes plugged into a NI BNC2110 DAQ but for some reason it's collecting a specified amount of data from one channel then it moves onto the other. I'd like for these to be collected at the same time but cannot figure out how to do it.
I've attached my code as well as a sample of the data I've collected from a HeNe laser power fluctuation. After viewing the image you should see that Channel 2 is distinctly out of phase from Channel 0 whereas these should be directly in phase. Weird.
Any help would be appreciated.

Light Sensor Comparison.vi ‏68 KB
Phase Difference problem.PNG ‏82 KB

It's not at all weird since that is the way you programmed the acquisition. You have one task for one channel that you start and then stop and then you start/stop a task for a different channel. You need to have a single task with both channels specified in the physical channel constant and change from 1Chan NSamp to NChan NSamp.
p.s. You don't have any sort of loop. Please don't say you are using the Run Continuous button. If you are, stop doing that and place a while loop around the code you want to run. The code up to the Start Task and the Clear Task should be outside the loop.
