Well, if you don't want to switch to the microsoft virtual machine, you can try the classes from nevaobject.com. These will allow you to use the sun jvm and work with com objects. Using these is a bit combersome, but I can attest to their validity. Here is the link.

If you want to persue this, I would be happy to provide code examples.

Calling a soap web service from a java desktop application

Hi,
Does anyone know how to call a soap web service from a java desktop application? I've seen examples using Apache Axis, but it sounds like Axis needs to run on a web server and we are trying to avoid that. My initial thought was that, "of course we need a web server", but I'm wondering if there is a way to do this without a web server.
Any help is greatly appreciated.
thank you,
Julie

If you are the consumer you don't need any web server. The web server is only needed in the provider end.
In java 6 there is a built in framework to call web services without the need of third parties (such as apache axis)
take a look at:
https://jax-ws.dev.java.net/guide/Developing_client_application_with_locally_packaged_WSDL.html
http://java.sun.com/webservices/technologies/index.jsp
For the provider end there is also a built in http server to expose web service via HTTP without the need to
use any external web server.

How to call a PL/SQL procedure from a Java class?

Hi,
I am new to the E-BusinessSuite and I want to develop a Portal with Java Portlets which display and write data from some E-Business databases (e.g. Customer Relationship Management or Human Resource). These data have been defined in the TCA (Trading Community Architecture) data model. I can access this data with PL/SQL API's. The next problem is how to get the data in the Java class. So, how do you call a PL/SQL procedure from a Java program?
Can anyone let me know how to solve that problem?
Thanks in advance,
Chang Si Chou

Have a look at this example:
final ApplicationModule am = panelBinding.getApplicationModule();
try
     final CallableStatement stmt = ((DBTransaction)am.getTransaction()).
                                                                                     createCallableStatement("{? = call some_pck.some_function(?, ?)}", 10);
     stmt.registerOutParameter(1, OracleTypes.VARCHAR);
     stmt.setInt(2, ((oracle.jbo.domain.Number)key.getAttribute(0)).intValue());
     stmt.setString(3, "Test");
     stmt.execute();
     stmt.close();
     return stmt.getString(1);
catch (Exception ex)
     panelBinding.reportException(ex);
     return null;
}Hope This Helps

It was possible to do it in ASP .NET even from the server side with the method Page.ClientScript. What do you think what Page.ClientScript stands for?
I's an encapsulation for the JavaScript code required and hides the separation between frontend and backend. There was a reason why so many developers stick to the MVC-pattern wich ist violated here.
I did not know it is not possible to do the same thing in Java.I'ts not a task of the backend to layout the user interaction GUI.

Calling a Visual C++ COM from java

Hi all, I have a problem very strange:
I have developed , using JNI, a java class wich interacts with a COM Interface.
When I use the java class that implements jni connection form the main method in my java app, it works fine, but when I try to access this class in a different class outside main, I obtain an error creating the Com instance. Anyone knows why?
//C++ Com initialize
BOOL CECardIdWorks::Initialize()
CUtilLog oUtilLog = CUtilLog();
try
// Get our instance of the PrintServer's IDataInput interface:
HRESULT hr = m_pDataInput.CreateInstance(__uuidof(PrintServer::DataInput2));
if (FAILED(hr))
     oUtilLog.NuevoLog("CECardIdWorks","InitCard","Fallo en m_pDataInput.CreateInstance.");
          return TRUE;
catch (_com_error& ce)
oUtilLog.NuevoLog("CECardIdWorks","Initialize","Excepcion , Initialize exception.");
LogComError(ce);
AfxMessageBox("Initialize Exception. Exit");
return FALSE;
}

This is the C++ code part.

Calling Window's Dll Functions from Java

Hello Audience,
Is there a way to call Win32/64 based Dynamic-Link-Library functions from Java?
Thanks,
GenKabuki

Yes.
In general, if you are trying to call functions in an existing dll, you will have to write a "wrapper" dll that meets the java jni interface requires. There are tools around wich purport to generate these for you. Do a google serach; among other tools, you should turn up JACE.

Calling a webservice(JAX-RPC) from non java client ?

Hi,
I read JAX-RPC is used for accessing webservices by calling the webservice methods from a java-based client.
Is it possible to call the Webservice methods(writeen using jax-rpc) from a non-java client,who sends his request in the form of SOAP based calls?
If JAX-RPC is not the correct one to call a RPC from a non-java client,In what way i can do this?
Can anyone please clarify my doubt..,
Thanks in Advance
Rao.,

Hi Arun,
Can i write a my client program using cgi scripts?
In the JAX-RPC docs it was said that i can invoke my Webservices through my Service endpoints or using WSDL location?
If iam using a Non-java Client,it will be easier(I think) to use the WSDL file to call the Web-Service(deployed using JAX-RPC).But,the Client should be aware of that WSDL file.
I have to develop a small Application using webServices(must use XML,SOAP technologies).The user will pass some Parameters as request and the Response should be an XML(SOAP message) message.User should be able to request via browser.(http://localhost:8080/)
Can you please suggest me which technology is correct to use,so that i can use the XML,SOAP in it.
Please let me know...,
thank you once again..,
Regards
Rao.,

How to create context sensitive help and call the role based help from my Java Project?

Hello All,
I am new to Robo Help. I have created a Robo help for my Java Web Applicaion. My application is role base i.e some user's will not see some of the pages of the application. So I want to hide those pages in Robo help as well. I tried creating multiple TOC for different Roles.
My Question is
How to call robo Help from my application?(I will be calling using java script. If it is with RoboHelp_CSH.js where can I get that and How to implement it in my project)
How to implement role based help?
Thanks,
Siva.

I answered that. My point in asking whether it matters was that if it does, then you cannot use content categories and point different users to different categories and not allow them to see the others.
The alternative, as I said, would be to produce different outputs for each role.
As it does matter, then using webhelp you will have to use your RoboHelp project to produce a number of outputs, one for each category. Your app would install each webhelp into different folders and when your app determines the user role, you will link to the appropriate help.
There is another thread running where it has been explained by Willam van Weelden that you can achieve what you want using browser based AIR help. If that form of help can be considered, then the thread is at http://forums.adobe.com/message/4914753?tstart=0#4914753
Browser based AIR help must be run from a web server. It cannot be installed locally.

LabVIEW call Win32 API DLL function from third party

Hi everyone,
I'm trying to build a LabVIEW 2010 interface on 32-bit Window XP system to configurate and communicate to an Anglient laser head through its USB expansion box. I contacted the vendor and they shared a win32 API with some dll files. I started with a function called "A55292Find", but the CLF node always pop up error 1097.I checked the MSDN to get the corresponding LabVIEW data type for CLF.
My question is: Do I need to initialize those arguments? (How can I know the values of them if initialization is needed?)
Could anyone help me figure out what's the problem?
Here is what I have from API documents about this function:
The A55292Find function returns lists of handles and board types for all the 55292 USB
Expansion Modules connected to the system.
A55292RC __cdecl A55292Find(
HANDLE hBoxes[], // List of handles for the boxes found. (as Unsigned 32-bit integer numeric)
BOARDTYPE PortABrdType[], // List of board types for slot A boards (as Unsigned 16-bit integer numeric)
BOARDTYPE PortBBrdType[], // List of board types for slot B boards (as Unsigned 16-bit integer numeric)
WORD *spMaxBoxes); // dimension for all of the passed arrays. (as Unsigned 16-bit integer array data pointer)
// (function return type as Unsigned 32-bit integer numeric)
Parameters
HBoxes[] Array that will receive the list of HANDLES for all the 55292 boxes connected.
PortABrdType[] An array that will receive Slot ‘A’ board type information for each 55292 box.
PortBBrdType[] An array that will receive Slot ‘B’ board type information for each 55292 box.
spMxBoxes Passes the maximum number of values that can be held in hBoxes, PortABrdType, and PortBBoardType arrays to the A55292Find routine and returns the actual number of boxes found
The return value will be one of the following A55292RC return codes:
Value Meaning
A55292_NO_ERROR No error
A55292_TIMEOUT Timeout accessing a shared memory
Remarks
This routine must be called to obtain handles and board type information used in calling all the other routines. If there are significantly more array elements than boxes, the routine will take longer to complete.
These are the definitions:
typedef DWORD A55292RC; enum{A55292_NO_ERROR, A55292_HANDLE_ERROR,...}
typeder WORD BOARDTYPE; enum{A55292_PCAL_BOARD, A55292_NO_BOARD, ...}
Thanks a lot,
Kang

Hi Mr. Kalbermatter,
As you told me, I should try to use the defined enumeration words as control and indicator.
For the previous CLF node, it successfully returned the hardware configuration (I have only connected a board at slot A):
But I really want to see a string return as "A55292_PCAL_BOARD" which is defined by "typedef WORD BOARDTYPE; enumeration {...}; Does that mean I need to change the data type or do something like "converter"? Or initialize the array first, then convert it to string type?
Right now, I'm trying to open the laser card by using "A55292PcalOpen(HANDLE hDev, SLOTSELECT SlotSelector);" function which requires to use the enumeration constants from " typedef WORD SLOTSELECT; enum {A55292_PORT_A, A55292_PORT_B};" but I'm confused to shot an constant control to a new CLF node.
Since almost all of the arguments in dll function are typedefined as WORD, short and struct et al, I hope you could give me some hints on it.
Thank you very much sincerely!
Kang
Depending on the actual C implementation you can simply create a LabVIEW enum with the according item names or use a ring control instead. Teh enum requires the numeric values of the items to be in consecutive order without any gaps in between. This is a given if the C definition never assigns a specific number to the item. If the C enum is not consecutive you need to go with a ring control instead.

Calling a already existing mapping from a java mapping

Hi.
Is it possible to get a reference to an existing graphical mapping in a new java mapping or new user defined function?
Rod

Hi,
If you have the mapping to run one after another and you need the output of mapping1 as input of mapping2 then you can add this in Interface mapping one after the other with required Message Interface.
Don't know if you can refer to a standard Graphical mapping in a Java mapping?

When to call a BAPI inputexecute method from webdynpro-java?

Hello... I'm a little concerned about a situation I'm having. The thing is that I'm trying to use the Bapi_Qualiprof_Change bapi with some test and hard coded data for a future application. It works fine if I fill the input profile_add table in the init() method of my view and then directly call the onActionModifyQualification method (inside the same init() where i filled the parameters).
On the contrary, if I change the code that intializes the data to the onActionModifyQualification or create an special method to initialize it wich is called later with an action button, then it doesn't work.
After many test I noticed that i have to call the bapi execute method right in the init... is there something I can do to fix it? or is it that i must do it in order to make it work?
I have my controller's context mapped to the bapi's model and the view context mapped to the controller's one.... is it good or do i have to build a similar structure to capture the parameters before and then copy the values into the controller's context??
Thanks a lot!!

Thanks for your answer, but it doesn't let me do that because wdModifyView is static. Therefore if 2 people are trying to use it, it's goning to be all mixed up, isn't it?
Anyway, what I really want is executing the bapi when I press the button (that's when it should call the action that calls the bapi). But it only works if I call the action in the init method.
