Catching external errors

I hava a program which uses Runtime.exec() to call an external tool (.NET wsdl.exe)..
This has to be in a try/catch block, but as the wsdl.exe is external an exception won't be thrown if an error occurs.
Can I use the returned process to determine if the wsdl.exe ran successfully?
Thanks.

You can use the Process object to get feedback from the program, or interact with it.
Read the API doc (check the waitFor() method).
Have a lok at this article to get more info and code samples.

  • How can I catch a error in a BAPI?

    Hi,
    I use BAPI L_TO_CREATE_MULTIPLE. If, for example, I put a warehouse that not is the warehouse of the unit that I want to move, I receive an error that isn't in exceptions.
    In the program, I need, in the sy-subrc, catch this error, to do anything.
    In this case, the message is L3208.
    Thank you very much.

    Hello Jose
    BAPIs must not raise any exceptions. Why? Because they are intended for external use. However, if you raise an exception during a RFC call the connection will break down. Therefore BAPIs collect the error message in their (usually named) RETURN parameter.
    In order to evaluate a BAPI call you can simply code like this:
    " Assumption: RETURN parameter is an itab of type BAPIRET2
    LOOP AT return TRANSPORTING NO FIELDS
              WHERE ( type CA 'AEX' ).
      EXIT.
    ENDLOOP.
    IF ( syst-subrc = 0 ).
    " A(bort), E(rror) or X(dump) happened
    ENDIF.

  • Catching an error in SUBMIT Statement

    Hi,
    I am using SUBMIT (REPORT) and RETURN.
    How to catch an error when there is one in the  REPORT Program that i am calling.

    hi
    Calling Programs
    If you need to program an extensive application, one single program can become very complex. To make the program easier to read, it is often a good idea to divide the required functions among several programs.
    As well as using external modularization, in which you store procedures in special non-executable ABAP programs like function groups, you can also call independent programs from within an ABAP program.
    The following ABAP statements allow you to start an executable program or transaction. You can either exit the calling program, or have the system return to it when the called program finishes running.
    Executable Program
    Transaction
    Call without return
    SUBMIT
    LEAVE TO TRANSACTION
    Call with return
    SUBMIT AND RETURN
    CALL TRANSACTION
    You can use these statements in any ABAP program. For example, while processing a user action in the output list of an executable program, you might call a transaction whose initial screen is filled with data from the selected list line.
    The event LOAD-OF-PROGRAM is triggered each time a program is called. If a corresponding event block is defined in the framework program, it is executed once before the first other processing block is executed.
    An interesting remark at this point is that each execution of an executable program actually has a SUBMIT statement as its source. When you enter the program name in a transaction like SE38 or SA38 and choose Execute, a SUBMIT statement occurs in the transaction. Technically speaking, therefore, executable programs have the attribute of being able to be called using SUBMIT, although their principal characteristic from a useru2019s point of view is that they are started in the foreground.
    Memory Organization in Program Calls
    The first ABAP program in a session on the application server opens its own internal session (roll area) within the main session. All externally-called procedures run in the same internal session as the calling program, that is, the main program and working data of the procedure are loaded into the same memory area in the internal session.
    When you call an executable program or a transaction, the system opens a new internal session for each program. Here, there are two possible cases: If the second program does not return control to the calling program when it has finished running, the called program replaces the calling program in the internal session. The contents of the memory of the calling program are deleted. If the second program does return control to the calling program when it has finished running, the session of the called program is not deleted. Instead, it becomes inactive, and its memory contents are placed on a stack. The system can open up to 9 further internal sessions in external program calls.
    As well as executable programs and transactions, dialog modules also open a new internal session. Dialog modules were previously used for modularizing screen sequences.
    Program Calls and SAP LUWs
    An SAP LUW is a logical unit consisting of dialog steps, whose changes are written to the database in a single database LUW. There are various bundling techniques that you can use to ensure that all of the database updates belonging to an SAP LUW are made in the same single database LUW.
    Externally-called procedures do not open a new SAP LUW.
    However, when you start a new executable program or transaction, a new SAP LUW starts. Database updates belonging to these programs are collected in their own database LUW. If the new program does not return control to the calling program, the SAP LUW of the old program concludes when the new program is called. If, on the other hand, the new program does return control to the calling program, the new SAP LUW runs parallel to the SAP LUW of the calling program.
    No new SAP LUW is opened when you call a dialog module. Bundling techniques in a dialog module add the database updates to the database LUW of the calling program. You may sometimes need to call a transaction that runs in the same SAP LUW as the calling program. One technique for doing this is to use the existing transaction as a dialog module. To do this, you need to create a new dialog module with the same main program and initial screen as the transaction. Transactions that are used both as transactions and as dialog modules must be programmed to obey certain rules. For further information, refer to Calling Screen Sequences.
    The fact that an external program shares (or does not share) the SAP LUW with its caller has special consequences if the program calls update-task functions or uses COMMIT WORK. For further information, refer to Special LUW Considerations.

  • Catch the error in to a log file

    Hi Team,
    Created the script for testing the server online or offline, Could you please tell me how to catch the error in to a file
    Try
    $Result = Test-Connection -count 1 -computer (Get-Content ServerName.txt)  -ErrorAction "Continue"
    Catch
       $Result = New-Object PSCustomObject -Property @{
                TimeStamp = Get-Date
                __Server = $env:COMPUTERNAME
                Address = $Computer
                Protocol = ""
                ResponseTime = "Failed"
    $Result | Select TimeStamp,__Server,Address,ProtocolAddress,ResponseTime | ft -AutoSize

    As mjolinor pointed, you should change the -ErrorAction to Stop to make the control flow into catch block when error occurs. Just change alone is not sufficient because, the control will go to catch block if any of the computer in servername.txt gives error,
    and it will not go back to next computer in your text file perform the ping.
    So try chaning the code as shown below.
    $Outarr = @()
    foreach($Comp in (Get-Content C:\temp\servers.txt)) {
    Try {
    $Result = Test-Connection -count 1 -computer $Comp -ErrorAction stop
    Catch {
    $Result = New-Object PSCustomObject -Property @{
    TimeStamp = Get-Date
    __Server = $env:COMPUTERNAME
    Address = $Comp
    Protocol = ""
    ResponseTime = "Failed"
    $Outarr +=$Result
    $Outarr| Select TimeStamp,__Server,Address,ProtocolAddress,ResponseTime | ft -AutoSize
    Hope this helps.

    You can simplify that to:
    $Outarr =
    foreach($Comp in (Get-Content C:\temp\servers.txt)) {
    Try {
    Test-Connection -count 1 -computer $Comp -ErrorAction stop
    Catch {
    [PSCustomObject]@{
    TimeStamp = Get-Date
    __Server = $env:COMPUTERNAME
    Address = $Comp
    Protocol = ""
    ResponseTime = "Failed"
    $Outarr | ft -AutoSize
    The [PSCustomObject] type accelerator will take the hash table as a constructor, and coerce it to an [ordered] hash table, so the properties will stay in the same order they were declared.  That eliminates the need to use Select-Object afterward to
    get them back into the right order.

  • Catch all error information while validating xml content with xsd schema

    Hi experts,
    I created a java mapping to validating the input xml content with xsd schema (schema validation). What I want is to catch all error message to the xml not just the first error. I used SAXParser in sapxmltoolkit.jar to do the schema validation. The below is a part of my java mapping.
    XMLReader parser = XMLReaderFactory.createXMLReader("com.sap.engine.lib.xml.parser.SAXParser");
    parser.setFeature( "http://xml.org/sax/features/validation" ,  true);
    parser.setFeature( "http://apache.org/xml/features/validation/schema" , true);
    parser.setProperty("http://java.sun.com/xml/jaxp/properties/schemaLanguage", "http://www.w3.org/2001/XMLSchema");          parser.setProperty("http://java.sun.com/xml/jaxp/properties/schemaSource",this.getClass().getClassLoader().getResourceAsStream(schema)); // schema is my schema name
    parser.setErrorHandler(new ParseErrorHandler()); // ParseErrorHandler is my own ErrorHandler which extends DefaultHandler
    parser.parse(new InputSource(new ByteArrayInputStream(sinput.getBytes())));
    // In error handler, I comment all code so as not to throw any exception
    public class ParseErrorHandler extends DefaultHandler
         public void error(SAXParseException e) throws SAXException

         public void fatalError(SAXParseException e)

    fault message type

    Hi Spring,
    If u give an exception step along with your Transformation Step, whenever some error occurs in your message mapping, this exception block wil be triggered.
    You can configure your exception block to do all exception processing that you want. This exception handling is like any other java Exceptio n Handler. You can do anything that you want in your exception handler block on the basis of your requirements.
    <i>If an exception is triggered at runtime, the system first searches for the relevant exception handler in surrounding blocks. If it does not find the correct exception handler, it continues the search in the next block in the block hierarchy.
    When the system finds the correct system handler, it stops all active steps in the block in which the exception handler is defined and then continues processing in the exception handler branch. Once the exception handler has finished processing, the process is continued after the block.
    If the system fails to find an exception handler, it terminates the integration process with an error.</i>

  • Catching all errors

    Hi
    is there a way to catch all errors, I know you can do try and
    catch fro your code
    about how about errors that come from built in Flex component
    I am trying to catch all errors and show it to the user in
    better format
    but most important, it seems flex will be frozen and you can
    do anything if the error is not caught and the only way around it
    to restart your browser
    Please help
    Thanks
    Kasem

    Everything I read suggests that this isn't possible in Flex.
    It seems that uncaught exceptions are handled by the Flash player.
    This link discusses the problem in Flex 1.5 and it notes the
    problem is not fixed in Flex 2.
    http://www.mail-archive.com/[email protected]/msg25874.html
    I'm going to continue to look. I really can't imagine that
    Adobe spent all that time reworking Flex and didn't address this
    problem.

  • Linker "unresolved external" error

      I have a large project written in straight C that Visual Studio 2013 (with a little forcing) compiles and runs without error.  I have written a C++ shell around it to create a new project.  Everything works except that I get
    the “unresolved external” error for every instance of my C-style declarations, i.e., where I declare a variable directly with first use, and forever thereafter declare it with the “extern” keyword. How (exactly) can I fix this?  

      I found the “unresolved external” problem.  What happens is that VS will not “port” an initial declaration in a .cpp file into a set of .c files (and vice versa) so when it hits my “extern” declarations in the set of .c files which I assumed
    would be associated with the initial declarations in the set of .cpp files in my .cpp shell, It thinks none of them has a legitimate initial antecedent.  Since I need only two .cpp files in the shell, this was easily fixed.  However, the project
    still won’t compile because I have apparently not set up my header files properly.  This results in hundreds of errors like the following, where VS attacks and rejects its own MS code:  “IntelliSense: declaration is incompatible with "double
    __cdecl acos(double _X)" (declared at line 474 of "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include\math.h") c:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include\cmath.” I might eventually be able to “fiddle” my way to
    a solution, but any help would certainly be appreciated.

  • Catching an error on a single line

    Is there a way to catch an error on a single line in a VBS script? From what I understand the "On Error Resume Next" will apply to all lines in a procedure.
    George

    Hello George,
    unfortunaly there is no way in VBS like the On Error Goto xxx in VB/VBA. You have to encapsulate the crtitcal lines with a On Error Resume Next/On Error Goto 0 pair and find an error with if Err.Number <> 0 then after every line and handle it e.g. with a Exit Sub call.

  • How to catch BCD_OVERFLOW error when passing value to formal parameter?

    Hi,
    catching runtime error BCD_OVERFLOW exception is simple. However, it's not possible to catch this error directly, if it results from assigning too big value to the formal parameter.
    Let's assume simple code with local class lcl_calculator implementing functional method add with two input parameters i_op1 and i_op2 both of type i and result value r_result of type i as well.
    The following code dumps, without the exception being caught:
    DATA:
       lo_calculator TYPE REF TO lcl_calculator,
       l_result TYPE i.
    START-OF-SELECTION.
       TRY.
           CREATE OBJECT lo_calculator.
           l_result = lo_calculator->add(
             i_op1 = 10000000000
             i_op2 = 1 ).
           WRITE:/ l_result.
         CATCH cx_sy_conversion_overflow.
           WRITE:/ 'Error'.
       ENDTRY.
    To solve this, the workaround has to be implemented with checking the values being passed to the method before the actual call is made:
    DATA:
       lo_calculator TYPE REF TO lcl_calculator,
       l_result TYPE i,
       l_op1 TYPE i,

    It's the same with the function module call, so it's general unit interface issue. Also, using the exception handling related to the CALL METHOD command does not help here as it's not wrong parameter TYPING which causes the error. It's the VALUE of correctly typed parameter that causes the error.
    The CATCH apparently reacts different ways when the assignment is made to the variable and to the formal parameter of the unit. Any idea how to solve the above without using that workaround?
    Thank you

  • Idoc ORDERS returned by PI with message "External Error Header Received"

    Hello,
    I would appreciate if somebody can help on this :
    I'm sending idocs ORDERS05 from R/3 4.6C to PI 7.01.
    Idocs are generated and sent successfully from R/3 but are not generated in PI.
    From R/3, Idocs are visibible in T BD87 and are classified under "Idocs in target system" with :
    - status 56 : "External Error Header Received"
    - idocs have a number in R/3 but no partner idoc number
    - Partner number is the purchase order vendor number
    Thanks a lot for your help.

    Hello,
    Thanks a lot for those helpful replies.
    Looking in the sxmb_moni, xml messages is blocked and error message is "Error while reading ID of own business system from
    the SLD for system SND and client 320"
    -I have ckecked the SLD and technical system SND-320 is well linked to business system SND-320.
    -I have ckecked SM59 and tested the html link between XI and SNC but reply is "empty reply". Am I supposed to have a positive check at this point ?
    -I have checked my distant user in SAP SNC and change its role to SAP_XI_IS_SERV_USER_MAIN
    Concerning we20 in XI, I can't declare an the HTTP connection SND-320, not recognized as a Logicial System
    At this point, Idocs are reaching XI from R/3 but don't reach SNC.
    Regards,
    Cédric

  • Catching Mapping error at runtime using a udf

    Hi AlL,
    I read some blog where it was discussed.. we can catch runtime error ? Is it possible?
    how will we be able to catch the runtime error say during the mapping we got an error and we want to catch that error and log it somewhere or throw user defined exception?
    I guess at runtime all the runtime details are stored in SMPPMAP3 table. which is the field which contain the any runtime error?

    Hi,
    you cannot do it using an UDF as a uDF will only work on fields that
    are in the message
    you can throw exceptions from UDF but not catch
    to catch you can use an exception branch of a block stpe in an intgration process BPM
