Call External C++ function and pass XML

Hi,
I need to call external C++ function from Oracle and pass to it XML file from Oracle table? Can you give short guide how to do it?
Regards

Your question sounds like is about using an Oracle database (or other application), and not about C++ programming or the using the C++ compiler. You are more likely to find a helpful answer in an Oracle database (or other application) forum.

How to connect to external web service and convert XML to a table

Hi experts,
I need to connect to external/non-SAP web service and convert XML in that site to a SAP table?
Is there a function call(SE37) to do this? Is it a must for me to install AS JAVA or PI and configure enterprise service? Please provide a link for me to retrieve relevant infomation, thx.

No, you don't need PI or the Java stack for this. You can create an ABAP proxy using the WSDL file for the web service and call the web service using the proxy class in an ABAP program. You can transform the XML response to internal tables/structures/variables using a transformation template that you create.

FRM-40734 when calling external DLL Function from Forms 6

Even though some answers were given to my previous help request ("Again: Forms 6 and user-defined data types") I wasn't able to solve the problem of passing a parameter of an user-defined type to an external DLL function residing in the SECURSIGN.DLL library (the closest solution was to declare that "composite" parameter using the ROWTYPE clause referencing a custom-made table created just for the sake of defining that perticular datatype).
So I concentrated on SECURSIGN.DLL functions using more trivial data types, like a function requiring just four character strings as parameters.
I generated the necessary PL/SQL support using the FFI.
I discovered that also the simplest calls to external functions fail at runtime with the generic error FRM-40734.
I located the error: it happens just at the moment of calling the function from within the FFI-generated package body. Before that, the DLL is loaded with no problem, the function is correctly registered, and a function handle is regularly returned.
As long as I can regularly issue the very same call with the very same parameters from Visual Basic, I can't understand what's going wrong (ALL the needed DLL are in the same directory as the FMB/FMX forms).
I will greatly appreciate any help that You may be able to provide.

I have noticed just now that a dump file having a name like ifrun60_dump_299, is generated by FORMS every time I issue the aborted call to the foreign function.
Inside the form dump file, apart from useless info like Registers and so on, the message:
"Could not find Module32First"
By a FILE/FIND/CONTAINING TEXT I searched all the DLLs, and I noticed that Module32First is a routine that can be found within each of the following DLLs:
Cl32
d2kwut32
d2kwut60
I tried to load those DLLs along with SECURSIGN.DLL by modifying the PROCEDURE LoadLibrary into the FFI-generated PLL code, and I have apparently no problem in loading all the DLLs that I wish, but the error persists, and that dump file is constantly generated, always looking for the "Module32First" routine.
How can I avoid all that mess and the FRM-40734 error??

Creating a print button to call a Report Query and pass filters

If i use the REPORT QUERY option in APEX 4 to create an statement that is the same one used in an interactive report, can I create a link or button to the REPORT QUERY and pass all the session and filter information from the interactive report to the report query?
This way I can have the interactive report screen where the user can do all sorts of modifications and such and then pass those to the REPORT QUERY so I can call that from a custom link or button.
You may ask "why does he need another print button?"
Answer: I am using a view that has some embedded HTML tags to format the output really nicely. The HTML download version created by the interactive reports works beautifully. The customer also wants a PDF version (meh) which does not render the HTML tags and actually echos them as part of the text. I found that I can create another view that uses the CHR function to create all the breaks and such I was doing with HTML and these do render properly in PDF. So, I figured just have 2 reports: 1 Interactive and 1 using a REPORT QUERY. I just want to call the REPORT QUERY version but use the Interactive Search form to set all the parameters.
Or, am I over thinking this and there is an easier method?
I made a previous post where I showed how I got the APEX printing to work and i hoped that helped someone out - fixing this issue would put the whole thing to rest.
Thanks

Is BI Publisher desktop (MS Word add-in) a possibility? This would allow you to use MS Word to create your output template (RTF) that would result in a properly formatted PDF. Of course, you'd have to right an updated version of the query without HTML embedded. Just thinking outside of the box.

Workflow step (Approve Action) calling custom Java Service and "passing params"

Good Afternoon, Fellow Coders!
Normally I research and do proof of concepts until I find a solution but given super tight deadlines, I just don't have time - so I need your help.
I am trying to have an Workflow Approve Action (Workflow Exit Event idocScript call) call a Custom Component (Java Service) AND "pass" some kind of parameters (bare minimum dDocName)
In a perfect world it would be as simple as: processContentInfo(String dDocName, String xMyCode1, String xMyCode2);
But since I am calling the Java Service from idocScript (via executeService) I cannot directly pass params via the API.
Is there a simple way to do this??
It seems like if you can't directly pass params you could at least set them in the managed container (m_binder) and just know to pick them up on the Java side via some DataBinder like m_binder.getLocal(
Am I missing a simple idocScript function that will let you do this?
Note: I am NOT executing the Service from a URL so the normal ?param1&param2 -> m_binder.getLocal solution is no good.
Also, Bex's book warns about Service Classes "not easily being able to call other UCM Services".... My Custom Service needs to do exactly that (as well as JDBC and other stuff). Is this really an issue??
Seems like as long as I have dDocName I could use RIDC to hit whatever I want as long as I know how to use a binder, etc - is there some mystic nuance that prevents this? Or was he just saying it's hard UNLESS you know RIDC well??
Any and all quality advice is appreciated! And please, try to give me a detailed answer as opposed to something vague like "try a Service Handler", I need something I can quickly digest.
Thanks in advance!

You can set parameters for the service call by setting Idoc Script variables before you call executeService.
<$dDocName="TEST12345"$>
<$param1="09876"$>
<$param2="ABCDEFG"$>
These variables are then available via the service DataBinder.
Here is information about how to execute a service from a custom component. There should not be any issues doing this.

Calling external C-functions in DLLs with struct as parameters

Hi all PL/SQL Gurus !
Is it possible to call external functions in a DLL written in C
wich has pointers to C-structs as parameter. Can you point me to
an example or extended documentation about this. I had a look at
the Oracle doc's but found no examples about structs.
Thank you very much,
Stefan.
P.S.: Konfiguration: Oracle 8.1.7.0.0 Client and Server on W2K-
SP2 machines.

Hi,
I have the same problem with you.Now,have you resolve the problem?
I want to know how to do.if you resolve it ,could you give me a example.
thanks .

Having problem with calling external javascript functions in LV

Hi,
I found this VI: http://lavag.org/topic/10304-discuss-calling-external-javascript/, which I believe can be really helpful for my work. The problem is I can't get it to run based on the following problem:
- Apparently the "ScriptControl" cannot be loaded
I am using LabView 8.6, and this vi has been produced in a 8.0 version. Do you think this is the problem? If not, what could cause this problem running this VI?
Thanks,
Diogo

Hi,
To start I am using this examplo from the google code page.
<!DOCTYPE html "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<title>Google Maps JavaScript API Example</title>
<script src="http://maps.google.com/maps?file=api&v=2&key=abcdefg&sensor=true_or_false"
type="text/javascript"></script>
<script type="text/javascript">
function initialize() {
if (GBrowserIsCompatible()) {
var map = new GMap2(document.getElementById("map_canvas"));
map.setCenter(new GLatLng(37.4419, -122.1419), 13);
map.setUIToDefault();
</script>
</head>
<body onload="initialize()" onunload="GUnload()">
<div id="map_canvas" style="width: 500px; height: 300px"></div>
</body>
</html>
It loads a basic map, and is saved in a html file created for example in Notepad. Basically as I said the VI is very simple, see next image.
But like I said, this strategy does not allow labview to interface dinamically with the javasscript code in the html file. Doing it this way, I would have to constantly update the code in the file with new coordinates and loading the map again. This causes the mentioned flickering problem that I also had with static maps.

When i click the listview items I have to call two odata webservice and pass that data to next screen ?

Hi All,
            I Have two odata webservices When i click the listview items I have to call that two odata webservice and pass that data to next screen ?

You don't have to pass the data to any page.
onInit method of controller set your oData model like this.
              onInit: function() {
              //var oModel = sap.ui.model.json.JSONModel();
              var oModel = sap.ui.model.json.JSONModel("http://services.odata.org/V3/Northwind/Northwind.svc/Customers?$format=json");
              sap.ui.getCore().setModel(oModel,"oDataId");
After this you can access your model from any views by just binding the elements with your odata. Suppose i have a table in a view of my application then i can write like this.
              var oTable = sap.ui.table.Table({
                     tableId: "myTable",
                     visibleRowCount: 5,
                     editable: false
              oControl = new sap.ui.commons.TextView({text: "{CustomerID}"});
              oTable.addColumn(
                           new sap.ui.table.Column({
                           label: new sap.ui.commons.Label({text: "Customer ID"}),
                           visible:true,
                           template: oControl
              oControl = new sap.ui.commons.TextView({text: "{ContactName}"});
              oTable.addColumn(
                           new sap.ui.table.Column({
                           label: new sap.ui.commons.Label({text: "Contact Name"}),
                           visible:true,
                           template: oControl
              oControl = new sap.ui.commons.TextView({text: "{ContactTitle}"});
              oTable.addColumn(
                           new sap.ui.table.Column({
                           label: new sap.ui.commons.Label({text: "Contact Title"}),
                           visible:true,
                           template: oControl
              oControl = new sap.ui.commons.TextView({text: "{CompanyName}"});
              oTable.addColumn(
                           new sap.ui.table.Column({
                           label: new sap.ui.commons.Label({text: "Company Name"}),
                           visible:true,
                           template: oControl
              oTable.bindRows("oDataId>/value");
Here you can see i have binded the oData with table.
Just what i am seeing that you are trying to pass this model to a page. You don't have to do so. Just bind your oData with relevant elements lite table or anything by writing like this.
oTable.bindRows("oDataId>/value");
these functions are different for different elements.
for listItem you may write like this.
              var oList = new sap.m.List({
              inset: true,
              items : [
                                    new sap.m.DisplayListItem({ label :"Category ID", value : "{oDataId>/CategoryID}"}),
{oDataId>/CategoryID} this has been used for binding.

Calling public package functions and variables through dblink

Is it possible to call a global public variable in a package in one database from another package procedure in another database using a database link? If so, could you let me know the syntax? Same question for package functions.

Hi,
check this documentation link especially the stmt...
http://www.mcs.csueastbay.edu/support/oracle/doc/10.2/appdev.102/b14251/adfns_packages.htm#i1007858
You cannot access remote package variables and constants.May be you can write a function in the remote db which when called will return the variable value.
for calling remote package functions...
syntax from documentation is [[schema.]package.]function_name[@dblink][(param_1...param_n)]
an example given in the above link for this...
EXECUTE fire_emp1@boston_server(1043);

Using Hibernate Functionality and pass it on to the JCAPS Oracle eWay

Hi All,
I need to use the Existing Hibernate API's and pass it on to the JCAPS oracle eWay to persist the Data.
As the present Application is using the Hibernate for persisting the Data as we have parent child relation with multiple tables , so we need to push the whole thing in to JCAPS.
Thanks & regards
Srikanth

Hi,
You cannot use hibernate using oracle or any other database eWays. If you want to leverage the same or the existing code you have for the Data Access you use JCD.
So what you can do is have the required jars available for the application and then use the available classes with in the JCD.
Thanks,
NarayanaaI don't think that is secesarily true. You can use oracle eWay to handle the database connection, pooling and XA transactions. You just retrieve the java.sql.Connection object from the eWay and use that in you hibernate code.

Calling a function and passing parameters via Variables

I've got an XML file that is loading in data and is calling functions.
I've figured out how to call the methods from classes with variables set from the XML file:
var functionToCall:String = xml.functions.func[0].to_fire.toString();
myClass[functionToCall]();
This calls the function perfectly.
I was wondering if there is anyway to pass parameters into the function as well through variables. Some functions may have no parameters, some functions could have 5... so the xml could be like this:
<functions>
   <func>
    <to_fire>function1</to_fire>
    <param>
     <value>true</value>
     <type>Boolean</type> 
    </param>
   </func>
   <func>
    <to_fire>function2</to_fire>
    <param/>
   </func>
   <func>
    <to_fire>function3</to_fire>
    <param>
     <value>false</value>
     <type>Boolean</type> 
    </param>
    <param>
     <value>My String Value</value>
     <type>String</type> 
    </param>
    <param>
     <value>10</value>
     <type>Number</type> 
    </param>
   </func>
</functions>
whats the best way to set something like this up?

how would I set something like that up?
in the class:
public function myFunction(_param1:String, _param2:Number):void {
then to call it, would ParamTypes be cast as an array or object or something?
var functionVariable:String = "myFunction";
myClass[functionVariable](??);
Or do I structure the XML file in some way to pass in the information?

Error while calling external library functions

Using visual studio I wrote the following code test javascript communication with external C/C++ libraries:
aabc.cpp :
extern "C" __declspec(dllexport) char* ESInitialize (TaggedData* argv, long argc);
extern "C" __declspec(dllexport) long ESGetVersion (void );
extern "C" __declspec(dllexport) void ESFreeMem (void* p);
extern "C" __declspec(dllexport) void ESTerminate (void );
extern "C" __declspec(dllexport) double AddNumbers(void);
double AddNumbers(double a, double b)
return a + b;
long ESGetVersion (void){
return 5;
And the code that I wrote in javascript is:
var obj = new ExternalObject("lib: aabc.dll");
alert(obj.version);
var aa = obj.AddNumbers(10, 20);
alert(aa);
It seems to me that it loaded successfully due to the output I am getting from the second statement. But I am getting error at the third statement where I called AddNumbers(10,20) function.
Somebody help me.
Thanks in advance,
sailu

I have the same problem. This is my code:
extern "C" __declspec(dllexport) char* ESInitialize (TaggedData* argv, long argc);
extern "C" __declspec(dllexport) long ESGetVersion (void );
extern "C" __declspec(dllexport) void ESFreeMem (void* p);
extern "C" __declspec(dllexport) void ESTerminate (void );
extern "C" __declspec(dllexport) int AddNumbers(int a, int b);
extern "C" __declspec(dllexport) char* ESInitialize (TaggedData* argv, long argc)
return "AddNumbers_dd";
int AddNumbers(int a, int b)
return a + b;
long ESGetVersion (void){
return 17;
And the code that I wrote in javascript is:
var obj = new ExternalObject("lib: mydll.dll");
var x = obj.AddNumbers(10, 20);
alert(x);
The version of the library is correct, but when I try to use the function "AddNumbers" I receive this error "AddNumbers is not function".
What would be the correct procedure to call a function inside a DLL?
