Multiple XML HTTP Data sources sequentially

Hi,
We are creating a report using multiple XML HTTP Data sources sequentially.
The Report uses multiple XML HTTP Data sources sequentially; the report creation fails or delayed. We would like to join the datasources after accessing from the HTTP Server.
At the same time the same XML files when locally accessing as data sources, the report is getting created.
Is there any alternate solution for XML HTTP Data Source Access. Or in which way I can proceed with this.
Thanks,
Unni

I am not able to use datasets here.
The context is as below.
I am running an HTTP server (XML-RPC program),which will generate an XML output as defined with a local XML Schema.
Here I have multiple HTTP requests ,each will generate multiple XML outputs.
I am using XML and WebServices Connection where I will provide like below,
(Please note file1,file2 are normal text files with data corresponds to xsds.)
HTTP(s) XML URL : http://localhost:8002/ReadTable?name=file1
Local Schema File : E:\Test\file1.xsd
HTTP(s) XML URL : http://localhost:8002/ReadTable?name=file2
Local Schema File : E:\Test\file2.xsd
Like this I am able to create multiple XML outputs through HTTP requests.(only file1),which means while creating reports the sequential requests are not handling properly.
My report will join say two of theese files. But at the time of report creation it will ask of only runtime parameter of first request in the join.
Here The report will generate only with data from first text(data) file.(file1)
Hope you got a clarity about the proble.

  • Are Multiple (Concurrent) ABAP Data Sources for AS Java UME Possible?

    Hi All,
    We have a solution which is using a JAAS logon module for partner authentication. for reason's I won't go into we have decided that it is best to use an ABAP data source. We will also be using the same JAAS approach for other ABAP applications in the future. Ideally we would configure the same JAAS server to use ABAP UME data sources from ABAP server 1 and ABAP server 2.
    I see there are provisions in the documentation for multiple UME data sources of different types but it doesn't clearly say about different concurrent data sources. IS this even possible? If so is it wise?
    Thanks,
    Doug

    Julius,
    Thanks again for your reply. This is confusing. We have an existing .Net logon application where we centrally administer accounts and where users log in. On successful login they are issued a .net Auth cookie. Our JAAS module takes that cookie, does a web service call back to .Net and authenticates them. So authentication is done on the basis of the .Net cookie, not the java UME. We simply need a java ume to allow users to execute the application that invokes the JAAS module. The application invokes the JAAS module and if they successfully authenticate they are forwarded to the requesting SAP application. So the JAAS ume is really just needed to allow various users to run the JAAS invoking application starter. Ideally we'd use the same starter application for users of SAP Application 1,2,3, etc.
    So that's where the question came from on multiple ABAP  UME data sources for a single Java instance.
    Hope that makes sense. Regardless the answer I guess is not possible but you see the method to our madness. And yes it is madness.
    Thanks,
    Doug

  • Multiple PS Query Data Sources in RTF Template

    Is it possible to use two PS Queries as Data Sources on an RTF template in XML Publisher?
    There is a field in the main Data Source (PS Query) that needs to join to some other tables. This slows down the query considerably even after tweaking the join and tuning, etc. Instead of doing the join in the main PS Query Data Source, can we do any of these?
    1. Do a select statement inside an RTF template Form Field?
    2. Use two PS Queries on the same RTF template?
    3. Import a sub template that uses its own PS Query Data Source for the field?
    Hope this makes sense. Thank you.

    You can have multiple data models and then use the 'concatenated SQL data source' to generate a single xml file that includes data based on both queries. You can not do a select statement inside a RTF template.
    Within the RTF template you can write logic to join the two data sets... see this blog post:http://blogs.oracle.com/xmlpublisher/entry/formatting_concatenated_dataso

  • Xml as data source

    HI, experts !!
    I have imported XML ("c:\xml_source.xml") as the data source.
    however, I found some data are wrong in the xml_source.xml file.
    then I edited the xml directly.
    But I found that the data keeps previous values on the dashboard.
    then I created a new xml file ("c:\xml_source_2.xml"). and change the xml url of the phyiscal table.
    but on the dashboard, it shows this error.
    Odbc driver returned an error (SQLExecDirectW).

  • Perform XSLT on XML as data source?

    Crystal Reports 2008 (12.0.0.549) can use XSLT when exporting an XML document.
    Can the XML driver, however, be configured to perform a XSLT on an XML document that will result in a document that will be used as a data source? 
    When I attempted to do so, I got an error--I was using an XSL document as the data source.

    Jamie-
    Thanks for the response.
    I'm trying to represent my résumé in XML format, then use Crystal Reports to generate a formatted, PDF document: craibuc/crystal-xmlresume · GitHub
    I'm hoping to avoid too much pre-processing, hence the desire to keep the data source in XML.  As such, exporting to CSV isn't an option.
    If this isn't possible, it would be a nice enhancement to the XML driver.

  • Add multiple simultaneo​us data sources to Continuous Measuremen​t and Logging Template

    I am looking at using the  Continuous Measurement and Logging sample project as a starting point for my project.  The template shows the use of a single data source at a single rate.  In my case I have multiple data sources that will arrive at different rates and need to come together and be logged to the same file with the fastest arrival dictating the log entry and the slower data would be their last values.  It is a slow data collecton process ranging from 1 second to around 10 second sample rate.  More of a monitoring application with logging than a data aquisition application. Since the waveform data type is base-t  plus delta-t and my data arrives at varying rates, my first task would be to remove the use of it and define a typedef for my data. I would use a single logging message loop, but what approach can anyone recommend for the aquisition?  I imagine separate aquisition message loop vis for each data source but what about placement?  Placing them all at the top level vs placing them within a the existing aquisition message loop vi? Any other thoughts or recommendation are appreciated.  Thanks in advance!

    if you want to sample one channel at 10/s and an other one at 1/second....  How is your file going to look like?  Does this mean that for the slower channel you just want to keep the same value for the other 9 values?
    The sampling speeds that you are talking about are really slow.  It would certainly not hurt your hardware to sample eacht channel with the same speed.  And it you really just need one sample every 10 second, you can always decimate you array of values.
    For instance :
    channel 1 : 1 point per second (sample ratio) => 10 points in 10 seconds
    Channel 2 : 1 point per 10 seconds => 10 points per 10 seconds (same sample speed) => decimate array (keep 1+/10 values) => 1 point per 10 seconds
    This is going to be the easy way, or you want to start with parallel loops running, but that's "not that simple" anymore

  • MX7 multiple instance jdbc data sources

    The data sources on my single instance install of MX7
    (Solaris9, Oracle9i), using jdbc, worked just fine. In a single
    instance install, the environment variables needed for jdbc
    (ORACLE_HOME, TNS_ADMIN, etc.) go in the start script
    $CF_DIR/bin/coldfusion. I've removed the single instance and
    installed the multi-instance version of coldfusion. I've been
    unable to get it configured correctly for jdbc. (The error message
    when attempting to verify a data source is, "blah, blah, no
    suitable driver available... please check the driver setting....").
    It would appear the the same settings should go in the
    $CF_DIR/bin/jvm.config file. I've done so but this does not help.
    What file do these settings need to be put into or does
    multi-instance require a different configuration for jdbc?

    Hello,
    A data source entry is for one single database, so if you have multiple database to connect into your application you must create 1 entry per database (eg: jdbc/database1 jdbc/database2)

  • How to create an XQuery for an XML type data source

    Hi,
    1.I have data contained in an XML format.
    Hence I have created a physical data source for XML type data.
    2.I have created a logical view to broker data from several disparate physical data sources.I have called this as UnifiedView.
    3.I have created a function called getUnifiedView() to obtain data from all the physical sources
    4.Upto this point, I have not faced any problems.
    5.However when i try writing a simple XQuery for the physical XML datasource such as
    $Sh-data/PublicIdentifiers/MSISDN="1234567"
    I get result as (For example):
    <HSS>
    <MSISDN> 1234567 111111 222222 </MSISDN>
    </HSS>
    Could you please help me getting the where clause output?
    I have attached the schema and XML files used for further information.
    Regards
    Vidya

    Hi mReiche,
    I later on resolved the previously mentioned error and try out the XQuery as suggested by you.
    for $MSISDN in ns0:Sh-data()/PublicIdentifiers/MSISDN
    where $MSISDN="1234567"
    return
    <HSS>
    <MSISDN>{data($MSISDN)}</MSISDN>
    </HSS>
    It works! Thanks.

    Next i want to match the SIP_URI in the HSS.xml with Contact of the Presence.xml
    Given below is the XQuery which i have written to achieve the above:

  • Accessing local XML as data source

    Are there any instruction on how to do this.  the Xcelsius 2008 user guide shows instructions for server side where a script is required.  I can't imagine that this would be required for a local XML file.
    thanks

    Martin, here is a short walkthrough I wrote:
    <br>Basic Workflow
       1. Enter the file path in the "XML Data URL" field (e.g. c:\documents and settings\user\desktop\xmlfile.xml)
       2. Click "Enable Load"
       3. Click the plus button for as many ranges as you want
             3.a. Each range name must correspond to a matching variable name in the XML file (so if you name Range_0 to "Test", there must be a variable named "Test" in xmlfile.xml)
       4. Bind the ranges to ranges of cells (e.g. A1 through A10)
       5. In the XML file referenced in Step 1, make sure there are data values to be read
       6. Set the Usage tab's refresh options or use a Connection Refresh button
       7. Run the model and verify that the data loads from the XML file into the cell bindings
    <br>The data that is read from the XML file into the Excel cells will be used as if it was entered manually into the embedded Excel sheets. It can be used by reference in other Excel cell formulas, by components, and in any other fashion that cell data can be used in Xcelsius 2008.
    Here is the basic format required of the XML file:
    <data>
    <variable name="Test">
    <row><column>1</column><column>2</column></row>
    <row><column>10</column></row>
    </variable>
    </data>
    <br>If the file contains 1 variable (the range) with 5 row tags, each row tag with 1 column tag and 1 data value, the data will be read into Xcelsius as...
    A1 = 10
    A2 = 2
    A3 = 13
    A4 = 4
    A5 = 5
    The range can be bound to any column; A1:A5 was selected arbitrarily for demonstration.
    Note that the range will not conform to the Xcelsius binding. That is, if the XML file defines 5 rows with 1 column, that corresponds to a vertical listing of 5 cells; so, if you bind the XMLData connection range to 1 row and 5 columns, you will only see 1 data value.

  • Logon failed when connecting to XML data source over HTTP

    I am trying to create a report using the standard report creation wizard:

    4) xml data source
    When using the sample from the SAP site, it works fine:
    http://resources.businessobjects.com/support/downloads/samples/cr/customer_db/customer.xml
    I have an HTTP source that generates XML. I have a schema that describes this XML. If I save the XML to a local file it works fine as a data source with the schema. However, when I try to access the same data via HTTP, I get the following error:
    Logon failed.
    Details: Cannot open file
    Server returned HTTP response code: 401 for URL: http://localhost:8004/report.xqy?Validate%20XML=0&Use%20WS-Security%20Config%20File=&WS-Security%20File%20Location
    However, if I enter that URL in a browser it works fine. And even if I disable security on the HTTP source, it produces the same error.
    Does the URL for the HTTP data source have to conform to some specific pattern? For example, must the URL end in .xml?

    Hi Pablo
    Thats a tough one ... if you go custom with a data template you will at least get support on the data template functionality ie you have a problem when you try and build one. You will not get support on the query inside the data template as you might have gotten with the Oracle Report, well you could at least log a bug against development for a bad query.
    Eventually that Oracle Report will be converted by development anyway, theres an R12 project going on right now to switch the shipped OReports to data templates. AT this point you'll be fully supported again but:
    1. You have to have R12 and
    2. You'll need to wait for the patch
    On reflection, if you are confident enough in the query then Oracle will support you on its implementation within a data template. Going forward you may be able to swap out your DT and out in the Oracle one without too much effort.

  • Using XML as a Data Source

    In http://download.oracle.com/docs/cd/E14571_01/bi.1111/e10540/datasource.htm#CHDBCAIJ it states you can use XML as your data source and mentions...
    URLs can include repository or session variables, providing support for HTTP data sources that accept user IDs and passwords embedded in the URL. For example:
    http://somewebserver/cgi.pl?userid=valueof(session_variable1)&password=valueof(session_variable2)
    I'm trying to pass this:
    http://somewebserver/cgi.pl?userid=valueof(NQ_SESSION.USER)
    but when I try that I can see in my web server logs that the content of the userid variable is 'valueof(NQ_SESSION.USER)' so it's not passing the results to the web server, just the text. Any ideas what's going on? Is my syntax correct? Thanks!

    Hey,
    There are a few things to look at when using session and repository variables within the RPD.
    One of the first documents you need to reference is the "What is the Syntax for Referencing Variable?" section within the OBI documentation. In addition look at this section on how to use variables in the RPD, http://download.oracle.com/docs/cd/E14571_01/bi.1111/e10540/variables.htm#BIEMG3104
    Basically you are trying to use NQ_SESSION.USER which is the syntax for trying to show the user name is Presentation Services. Of course you can see this in your web server logs because that is the correct syntax for presentation services web tier but not the RPD where you define your XML Source.
    You need to try either use VALUEOF("USER") or you are simply forgeting to put the syntax surrounded by single-quotes like, http://somewebserver/cgi.pl?userid='valueof(NQ_SESSION.USER)' to pull the system session variable into the XML URL as needed.
    Try those options and let me know if that works.
    Please mark this as the correct answer or helpful.
