Use of Process object

I'm doing a project for our company and I got to run 2 programs: one is the program to test and the others is a stub catching the values return by the first one. These 2 programs has to be started in a terminal in linux. The program to be tested is a C++ program and the stub is in Java. The problem is when I start the C++ program in bash the values returned are ok, but when I run it in a Process object the values aren't the same. I'm trying to find out why this program would return differents values than what it's suppose to when run in a Process object.
Thanks all

You may get a better response posting this question in an appropriate forum. This forum is concerned with J2EE. Why not try one of the Java specific forums, perhaps the J2SE Programming forum http://forum.java.sun.com/forum.jsp?forum=31

  • Servlet starting a .exe using the Process object

    Hi all,
    I need for a servlet to start another program.
    Here is some pseudo-code:
    public void post(....)throws ServletException, IOException
    //perform a bunch of operations
    at this point I need to launch a program to perform some
    operations on a saved file.  This program uses COM objects to do its thing.
    //start the process
    String cmd = "program's name";
    try
    Process process = Runtime.getRuntime().exec(cmd);
    process.waitFor();
    }//end try
    catch(Exception e)
    e.printStackTrace();
    }//end catch
    }//end post()My problem is this: The program will actually launch but dosen't seem to do any I/O. The program will not load the file nor will it write any log information. My thoughts are since the program is doing I/O in folders under Apache's DocumentRoot, Apache maybe blocking I/O.
    Any help will be appreciated!
    I'm using Apache 1.3.22 and Tomcat 3.3 running on Windows 2k.
    Thanks,
    Chris

    When you run your servlet which in turn starts your
    program .... is there any way of you to verify that
    your program was able to open the file ? Have you
    checked the Apache logs to see if you are getting any
    exceptions from the web container ?
    If you are could you please post it.

  • Creating a LOV by using a Command Object

    Hello All,
    I have a report that's driven by a parameterized sproc, which is a year parameter.  However, we have a table that I would like to use in my object command to populate this parameter with the values from the select statement to enforce consistency. A new year is inserted into to this table yearly by another process, which would keep me from having to go into a static list to update the year options yearly. 
    I've created the command object and saved it to the repository, but I can't figure out how to associate it to the report as the parameter.
    Can anyone point me in the right direction?
    Thanks in advance.

    hi DevinM,
    two choices:
    A) add the Command to your report
    1) you can add the Command to your report...don't link it to any tables though...you'll get a "Generally not supported error" but you can ignore it for this test
    2) now in your prompt you will have the Command available for the dynamic values
    3) check that the number of records on your report remains the same as before...it should...any test i have run on this is aok
    B) create a Business View
    1) go into the Business View Manager and create a business view from the data foundation up
    2) once you've got the business view built you can create an LOV from there which is available to your current report and all other reports

  • How to handle the Exception in GP using executable callabel object.

    Hi all,
            I handled an exception in GP using Background callable Object. That is working fine.
    (Ex: Exception_No_User_Found). The Problem is I am not able to handle the exceptions for normal callable object. I have done the same thing as i did in background callable object except implementing IGPBackgroundCallableObject Class.  I have created an WebDynpro DC Project where in getDescription method i declared an Exception and in execute method of component controller I caught the exception if no user found.
    Then i created an callable object for this simple DC project. but that is not working i could not catch the exception. when i execute the process it is asking the User ID if i give the wrong userId it is not refreshing back to the user id input form.
    But if i test that simple callable object separately it is throwing an Exception when I give the wrong input..
    but the same thing is working fine using background callable object.
    I couldn't handle the exception for the simple callable object or executable callable object.
    Please If anyone bring me the solution that would be appreciated.
    Thanks in advance.
    Regards,
    Malar.

    Hi Shikhil
    Thanks for your reply
    Please have a look below for exceptions which i am getting in GP and let me know how to handle these exceptions.
    1) "Activity could not be read"
    2) "Action has been stopped"
    3) error while processing the item can not be displayed
    if you give any idea/clue how to handle these exceptions then it would be great help to me
    Thanks

    Hi Ragav
    did you try to debug this? maybe something is missing in config of P&F?
    Since you are on 605, the following note would be there in your system....use it to debug:

    This will help you find the root cause.

  • Need Ideas for creating and using Custom Business Object

    Hello Guys,
    I am developing an application which uses a Request->Approve->Create approach for creating Purchase documents.
    Now I am a little puzzled about how to make use of the Business Object BUS2014.
    The application I am developing has its own unique 'Request Number'  (say REQID)  which will point to the Request for Creation of a purchase order.
    Whenever a Request is created (from a Z-Tcode) a workflow needs to be initiated and it has to be sent to the approver.
    The Purchase Document will be created once the approver approves.
    Now my confusion here is, if I use BUS2014, the object will be instantiated only during the final step of the workflow. But I need an instance during the beginning of the Requestor ->Approver negotiations as I am playing with events. These events needs an Object_key.
    How should I proceed here?
    Should I create a new logical Business Object like ZPOREQ where I have the above mentioned REQID as the key?
    And should I have an attribute of type BUS2014 inside the custom BO?
    How will I make use of the methods like BUS2014.Create etc which I may need to create the purchase document?
    Any small direction will be a huge help for me to get used to this wilderness.

    Hi,
    You should continue with the ABAP class idea. The business objects are kind of "obsolete" already, and if there is a need to create a new "object", ABAP classes are the way to go. Business objects are still useful, but I normally use them only when an existing standard business object fulfills the requirements (possibly with slight additions) which is almost never. 
    From my point of view you can use the existing class. Depending on the circumstances I normally have just one class that I use for both workflow and the possible other functionality that is required, but you have to understand that I have this goal in my mind already when starting the development process. As your class most probably has many useful features already (such as you have the header and item data as attributes etc. (if I understood correctly?), these are also useful in in workflow (class attributes will be available in WF container etc.). 
    If you are hesitant to use the same class directly in your workflow, you could also create a new class ZCL_REQUEST_FOR_WF (with the workflow interface), and then simply add your existing class ZCL_WF_REQUEST as an attribute to this new class. Then this new workflow class could include the pure workflow stuff, and your existing class the non-workflow stuff. But this most probably will not make much sense - just implement the if_workflow interface in your existing class (this is just one possibility that you might consider.)

  • Special characters in XML built using the DOM object

    I am using the DOM object to build xml but I am having problems with special characters. I have a Element object that I create attributes in. Most special characters like the &, ", or ' are translated for me (amp; quot;, acute; put a & in front of those, if I do it here the browser will translate them into the logical character) but I am having a problem with the � character. The DOM object does not translate this. If I do it my self to(eacute; same here add a & in front) before adding the string to the attribute then the DOM object translates it to (amp;eacute; add a & in front of the amp; not in front of the eacute;). As you can see the DOM object translates the & instead of recognizing that it is a HTML character. Can anyone give me a hand?

    I am building this XML in a servlet so ,right, DOM does process XML (even though a valid HTML file can be loaded into a DOM object) but if you build XML using DOM then write the XML out using PrintWriter and Transformer objects this will cause the XML to print out in your browser. If you view source on this XML you will see that the DOM object has translated all special characters to there &xxxx; equivalent. For a example: when the string (I know "cool" java) gets loaded into a attribute using the DOM object then wrote back out it looks like (I know &xxx;cool&xxx; java) if you view the source in your browser. This is what it should do, but the DOM object is not change the � to the "&xxxxx;". This servlet is acting as a gateway between a Java API and a windows asp. The asp will call the servlet expecting to get XML back and load it directly into a DOM object. When the windows DOM object gets the xml that I am returning in this servlet is throws a exception "invalid character" because the � was not translated to &xxxx; like the other characters were. According to the book HTML 4 in 24 hours (and other references) the eacute; or #233; are how you say "�" in HTML or XML. How do you say it?

  • How can a type defined in a PL/SQL package be used by an object?

    How can a type defined in a PL/SQL package be used by an object?
    In the PL/SQL Reference manual it says that object attributes can be
    types defined inside a PL/SQL package: How do you make this work?
    Here is a sample that demonstrates what I am trying to do:
    CREATE OR REPLACE
    PACKAGE Phone IS
    TYPE Phone_rectype IS RECORD (
    Main VARCHAR2(12),
    Home VARCHAR2(12),

    TYPE customer_type
    AS OBJECT (
    CustNo NUMBER,
    CustName VARCHAR2(30),
    PhoneNumber Phone.Phone_rectype
    This is the error that i get:
    Warning: Type created with compilation errors.
    Errors for TYPE CUSTOMER_TYPE:
    LINE/COL ERROR
    0/0 PL/SQL: Compilation unit analysis terminated
    5/15 PLS-00201: identifier 'PHONE.PHONE_RECTYPE' must be declared
    null

    That's a good point, Justin - thanks for the advice. At the moment, our process of data validation isn't very well defined, so the table definitions aren't always the same beyond a core set. As we get more automated and able to develop table definitions flexible enough to accomodate all the quirks in client data, I may be able to consider moving to a single schema to take advantage of maintenance and performance improvements. My ultimate concern with doing that is that the datasets we're dealing with can be tens of millions of rows in size. Clearly, I'm no DBA, but I just assumed that we would be able to churn through these datasets faster if they were in a schema by themselves rather than lumped together into one huge half-a-billion row table?

  • Where we can use standard ODS Object and Trasactional ODS Object ?

    Where we can use standard ODS Object and Trasactional ODS Object ?

    Hi,
    In a standard ODS object, data is stored in different versions (active, delta, modified), whereas a transactional ODS object contains the data in a single version.  Therefore, data is stored in precisely the same form in which it was written to the transactional ODS object by the application. In BW, you can use a transaction ODS object as a data target for an analysis process. The transactional ODS object is also required by diverse applications, such as SAP Strategic Enterprise Management (SEM) for example, as well as other external applications.Transactional ODS objects allow data to be available quickly. The data from this kind of ODS object is accessed transactionally, that is, data is written to the ODS object (possibly by several users at the same time) and reread as soon as possible.
    It offers no replacement for the standard ODS object. Instead, an additional function displays those that can be used for special applications.

  • How to count number of vehicles using image processing tools in LabVIEW

    anyone can give me idea that how to do counting of vehicles using image processing tools

    Hello,
    if camera is stationary, first take an image of the background. Then subtract each acquired image from the reference image. Limit the region of interest - build a mask of the area, where you want to detect vehicles. Use only the pixels that are under the mask for further processing. You probably would need to do some morphological operations (for example dilate) to make the detection more noise-free...
    Maybe you could get more reference images (different time of day) and compare the average intensities of the acquired and the reference image to select the best image for subtraction.
    You could then probably just count the numer of objects to get the number of vehicles.
    You can perhaps also use optical flow to track the vehicles, but you would need to compute some features for example strong corners for each vehicle (check good features to track, http://docs.opencv.org/modules/imgproc/doc/feature_detection.html). Or you can use the new mean-shift tracking library (Labview 2013).
    Hope this helps a bit.

  • FDM Scripting Query for last imported source file using Batch Processing

    Hi Experts,
    I'm currently in the processing of automating the FDM load process on our version of FDM 9.3.3 using batch processing and the FDM Task Manager. Most of the process works fine including an email alert which notifies users of when a data load has taken place.
    As part of that email alert I am trying to attach the source file that has been loaded in batch processing. I have managed to get an attachment using the following FDM Script Object of:
    "API.MaintenanceMgr.fPartLastFile(strLoc, True, False)".
    But have noticed that using this only attaches the last "manually" imported file rather than the last file imported using the batch processing.
    My question is: Is it possible for someone to steer me into the right direction of either a more appropriate API or if I have missed a step in my script.
    Any help as always would be much appreciated.
    Cheers
    Pip

    Unfortunately the batch process does not work the same way as on-line. I am assuming you are using the normal batch load and not Multiload (although the batch is simisar).
    the batch file name gets recorded on the tBatchContents table, and moved to the import/batches folder under the folder for the current batch run. However, if successful the file gets deleted (and from memory does not get archived). To add the import file to the e-mail, after a successful load, i think you will need to store a copy of it prior to importing the file.

    You will need to find a forum for MS Word since that is the software that you are trying to manipulate in this.  If you think the processing/creation of the PDF plays a role then you should ask in the forum for the software that you are using to create the PDF.

  • Missing Editor for Cancel Email in Start a Task Process object

    I'm using SPD 2013 and the 'Start a task process' object in a list workflow.  I've successfully modified the Task Creation email, but when someone completes the task, others in the group receive the default task cancelled email and I cannot find an
    editor to modify the cancel email.
    I can go to properties to view the CancelationEmailbody field, but there is no way to add or change lookup fields.
    Thanks,

    Hi,
    As I understand, you are using SharePoint designer worfklow on 2013 platform and you would like to edit cancelation email body for task process.
    From my experience, there is no OOB option for you to edit cancelation email body. Since workflow 2013 is different from 2010, task forms are auto-generated based upon a certain Content Type. As workaround, I'd recommend you using approval workflow on 2010
    platform. In addition, you could try codeplex 2013 approval workflow, please check the link below:
