How to call external C/java code in pl/sql or sql?

• How to call external functions without one. DLL (just using a.) H and. LIB file)?

  Hi all

  in fact, I am facing difficulties on how to get an external function is called in CVI (Version 2009).

  I was delivered with a. H file and a. LIB file to call an external function of my project CVI. The. H file looks like this:

  void exportedFunction(double *parameter);
  

  As far as I know, the external function was written with MS Visual C++ 6.

  So, I tried to link statically to the al extern like this function:

  -Add the. H file and the. LIB file to the CVI project

  -#include the. Folder H when I needed to call the external function

  -do the external function call

  During construction I get unresolved CVI external function call error, so this seems not work.

  I did some research autour and stood up with two possible problems. Maybe one of you can help me get a bit further and do work things out.

  (1) of the code of the 'real' function inside the DLL file that was not delivered to me. Or y at - it a way to get concrete results (calling external functions) with just one. H and a. LIB file (with none. Included DLL file)?

  (2) the external function does not export according to the rules of Style 'C '. The signature of the function in the. H file shows some things don't like

  extern "C" __declspec(dllexport) void __stdcall ...
  

  Or maybe it's a combination of these two issues (missing. DLL + bad export style function)?

  I guess I could get around the incorrect service export style when I managed to write a wrapper around the original function that actually uses Style C exporters. But I guess I need to the. DLL file for this test as well.

  Thank you very much for your answers.

  Best regards

  Bernd

  There is no need for the stuff of dllexport. There is also the option of a static library without any DLL.  But the "extern"C"' is essential, because it forces the C++ compiler, which was probably used to compile the library to use the C calling convention.

  If you are unable to ask the library vendor to provide a version that was compiled using C calling convention is the way to write a wrapper with VC ++ 6 around this library that functions using C calling convertion reexports. Something like

  extern 'C' myfunc1 type0 (type1 arg1,...) {

  Back to func1 (arg1,...);

  }

  for each function, you must use.

  BTW. "unresolved symbol" is the error message from the linker, you can expect if you try to bind the C code against a generation of library with the C++ calling convention.

• How to call external programs?

  I've seen people to call external programs through LabVIEW and was curious to know what functions you could use to do this.

  I'm sure that his works using one of the ActiveX or maybe 'open application reference .vi.

  Can someone tell me (or show me) a small example of how to open an external program (that is to say, excellent, Notepad, etc.) by programming

  HI Cory,.

  Take a look using the > examples > communicate with external Applications > ActiveX > Excel > Table write to XL.vi

  To take a step back and answer your Q in General.

  Required or possible methods to interact with external applications depends on of the external application and that she supported mechanisms.

  SysExec

  Used for tha programs can be called from a DOS command line.

  DCOM

  The app was to support this and that you are working with him to of peeks and pokes.

  ActiveX

  Only available on Windows, methods, and properties that depend on all of the app.

  Hi K159,.

  AFAIK ScriptUI CC does not implement ScriptUIFont at all

  Apart from that, SURROUNDED of NUMBER NINE is U + 2468, so using 0 x 2468 should lead to

  

  If your system font supports this character. But I don't know any way using your "NoName-6" police custom in ScriptUI.

• How to call a custom service Oracle11g UCM in Java to another component code custom?

  I have two Oracle UCM UCMComponent1 and UCMComponent2 components. UCMComponent1 has several custom services. My requirement is that I want to call UCMComponent1 service customized in the java method UCMComponent2.

  Anyone have an idea how I can do this service personalized in the Java method call? I know how to call the existing service of the Complutense University of MADRID in Java method.

• How can I get the exit code of a script .bat for Java back to PL/SQL?

  When you call a .bat script, only the exit code 1 returns. How can I get 7 back to the PL/SQL in the code example below?

  int exitCode = 0;

  Duration rt = java.lang.Runtime.getRuntime ();

  PRINT n

  DISPLAY ERRORS

  SELECT JavaRunShellCommand() AS R FROM DUAL;

  DISPLAY ERRORS

  HOST DEL v.bat

  OUTPUT

  It is strange that there are no errors. If the Java code does not work, I would expect an exception. Without an exception in the code handler, I expect to be propagated all the way to the top of the call stack and be displayed by the client. But there is no exception.

  So that means, in my view, that there is nothing wrong with the code Java itself. He made the appeal successfully to run this external process. The fact that the external process falls down, is not an issue/error in Java.

  If this is the case, then the first thing that comes to mind, is that the Oracle (oracle.exe) process that is currently running, runs as a service of the o/s. And that the service will try to run a command through the command shell script. There may be a security or problem access here that prevents the oracle.exe running as a service to do this.

• How to create a BPEL Process task using java code

  Hello
  
  I created a BPEL process (for creating task), in which my requirement is that I need to create a task based on some inputs and assign it to the user in partucular and then get out of this flow.
  
  earlier, I felt that I will use the human task activity. but when I use that task will be created in the same process and proceedings will be stuck on there until human intervention (the BPEL process waits for the result.).
  
  is it possible that I can use Java activity and create tasks from java code, 'I know how to assign a specific user task. Please tell me.
  Abhishek
  
  Published by: abhishek on April 25, 2011 12:42 AM

  Hi Abhishek
  1. you can try this alternative approach and it should work.

  2. basically, most of the BPEL process eventually auto generated Web services (.) WSDL). When we create a BPEL process, everything we do is give diagram of input, output schema and creates a bpel process with the default operation named as "process" in all the old versions as up to 11.2 SOA (and maybe before). BUT SOA 11.3 from, we can create a process BPEL, with our own WSDL and our own scheme. There is no restrictions like having only a single operation named 'process', etc.. In any case, what I mean is, each BPEL process ends up as a WebService, with entry and exit of the payloads of XSD.

  3. from the JDeveloper itself, locate the .wsdl for your BPEL process under the Workflow project. Create a new project of Proxy customer service Web and generate a customer for this wsdl Web service proxy. This will create you Service, Port and JAVA classes equivalent payload theoretically in your case taskpayload.xsd with these 4 items you have. Ignore the full blown the HumanTask which has all the system elements and attributes of a task of bpel. All you need is to undertake a task with your own payload data. Create a simple Client Java (EJB or Servlet later to make more flexible). In this Java client, retrieve the Service object in the proxy and port. Then instantiate the java class that represents the payload. Set 4 values you want and set the user name, etc. You may need some adjustments for the setting of the user. Then the port invoke otherwise (go your java object here).

  Sample code snippet
  prepare the message for BPEL of appeal; Define the fields that can not be null
  MyPayloadRequest myPayloadRequest = new MyPayloadRequest();
  myPayloadRequest.setInitiator("");
  myPayloadRequest.setTitle("");
  myPayloadRequest.setEmployeeName("");
  myPayloadRequest.setEmpContact("");

  web service client Get for BPEL receive point and call: first generate client proxy
  MyBPELPProcess_client_ep serviceClient = new MyBPELPProcess_client_ep();
  MyBPELPProces proxy = serviceClient.getNewMyBPELPProces_port ();
  proxy. Process (myPayloadRequest);

  Please note that you can also use the SOA workflow API and the Manager back call personalized for this first task classes. In this class, you can have the methods of the interceptor, which is called each time a task is initiated, saved, Submit, approve etc etc (all events essentially). This gives you access to all the objects in a workflow with full charge blown. So you can always get the data you pass above and in this custom class, the value of the user, date/time etc..

  It's just a different approach you can try.

  Thank you
