Call other DB from Form6i

Has anyone successfully set up Oracle Heterogeneous Services in Oracle 8.1.7 against MS Access on Windows 20000?
I modify tnsname.ora and listener.ora as documents in technet.oracle.com told me but it does not work. I receive errors that "ORA-02019: connection description for remote database not found".
How can I solve this problem? Any idea or anybody that success in set this thing up, please tell me.
Thanks in advance,

EJB 3.1 @Asynchronous and calling other methods from within

Hey all,
I am helping a friend set up a test framework, and I've turned him on to using JEE6 for the task. I am decently familiar with entity beans, session beans, and such. One of the new features is @Asynchronous, allowing a method to be ran on a separate thread. The test framework generally needs to spawn potentially 1000's of threads to simulate multiple users at once. Originally I was doing this using the Executor classes, but I've since learned that for some reason, spawning your own threads within a JEE container is "not allowed" or bad to do. I honestly don't quite know why this is.. from what I've read the main concern is that the container maintains threads and your own threads could mess up the container somehow. I can only guess that this might be possible if your threads use the container services in some way.. but if anyone could enlighten me on the details as to why this is bad, that would be great.
None the less, EJB 3.1 adds the async capability and I am now looking to use this. From my servlet I use @EJB to access the session bean, and call an async method. My servlet returns right away as it should. From the async method I do some work and using an entity bean store results, so I don't need to return a Future object. In fact, my ejb then makes an HttpClient call to another servlet to notify it that the result is ready.
My main question though, is if it's ok to call other methods from the async method that are not declared @Asynchronous. I presume it is ok, as the @Asynchronous just enables the container to spawn a thread to execute that method in. But I can't dig up any limitations on the code within an async method.. whether or not it has restrictions on the container services, is there anything wrong with using HttpClient to make a request from the method.. and making calls to helper methods within the bean that are not async.
Thanks.

Yes since the EE spec delegated thread management to conatiners, the container might assume that some info is available in the thread context that you may not have made available to your threads.
Also threading is a technical implementation detail and the drive with the EE spec is that you should concentrate on business requirements and let the container do the plumbing part.
If you were managing your own threads spawned from EJBs, you'd have to be managing your EJBs' lifecycle as well. This would just add to more plumbing code by the developer and typically requires writting platform specific routines which the containers already do anyway.

Thanks.If you want to be asynchronous without caring about a return value then just use MDBs.
The async methods have no restrictions on container services and there is nothing wrong with calling other non async methods. Once the async method is reached those annotations don't matter anyway (unless if you call thhose methods from a new reference of the EJB that you look up) as they only make sense in a client context.
Why do you need to make the call to the servlet from the EJB? Makes it difficult to know who is the client here. Better use the Future objects and let the initial caller delegate to the other client components as needed.

Call other programs from Java

There is this command line program I want to wrap with a Java class in order to make it available so that it can be transparently called.
How can I call or execute external programs/commands from JAVA...

Thank you

Runtime.getRuntime().exec("your command line")... you could read more about it in the API documentation.

How to call other execs from java application

What is the best way to make a call to execute an external executable written in another language (i.e. c++ or ada95) from within a java application?

Hi,
Runtime.getRuntime().exec(new String[]{"C:\\Office\\winword.exe"});
you should catch IOException as well.

Call other dc from dc

Hi Experts,
I created a PeoplePicker dc where I can search for portal users.
Now I want to use this dc in other dc. I thought about using a button which calls/opens the peoplePicker where I can search for a user, select it and return/pass that user to the first dc. I tried component usage and embedded the Interface View into a UIContainerElement. So I am able to display the view and search for the user. But I want to get the selected User back to my first dc with context mapping, but I don't know how.
Any ideas how I can resolve that
Best regards Manuel

Hi,
To make a dc available in another one
1) You have to have a public part
2) You need to expose the methods and context (if needed) using interface controller.
3) Expose views using interface views.
Following article explains this in detail

Calling other servlets from a servlet

Hi!
I'm new developing Servlets. I'm trying to include a request like this:
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter toAnotherServlet = response.getWriter();
RequestDispatcher sejuiste = config.getServletContext().getRequestDispatcher("/AnotherServlet");
if(sejuiste != null) {
try {
sejuiste.include(request, response);
catch (Exception e) {
System.out.println(e.getMessage());
toAnotherServlet.println("</html>");
toAnotherServlet.close();
In the compilation I have the following message:
config has private access in javax.servlet.GenericServlet
What I'm doing bad?
Thanks
Jogom

use getServletConfig() method instead of accessing the config object directly
the config object has private access, you can use it within
the GenericServlet class only.

Is it possible that vi form will remain contantly on screen even if I'm calling other vi's from testend test sequenc?

I'm using testend 3.1 & labview
7.1. For testing my UUT I'm using RS232 comunication. I want to
create a form using labview that will show all traffic via the rs232
port.
The problem is that the form is disappeared when I'm calling other vi from testend.

Hi ofer_o,
You could use the "Labview Utility/Run VI Asynchronously" Step to call your RS-232 vi.
See attached.

Is it possible to call other applet?

Hi Friends..
I want to know, is it possible to "CALL" other applet from one Applet?..
And is it a good implementation or not?..
Could you describe the Applet that call other Applet, perhaps through the example application maybe..
Thanks in advance..

Hi,
You can call the process method on another applet if you wish (if it is in the same package) or you can use Sharable Object Interfaces (outlined in the user guide). We have used SOI extensively to share data between applets in different packages (and as such different contexts on the card).
Cheers,
Shane

Calling diff infotype from another infotype!!

hi
is ther anyway i can call other infotype from my current infotype for eg suppose i am in my custom infotype and then i do some activities and based on which the value will b calculated and needs to be put into infotype 8.
regards
gunjan

Hi,
I tried this some time ago and found out that it did not work!
HR_INFOTYPE_OPERATION calls HR_MAINTAIN_MASTERDATA. This creats a batch-input which at the end calls dialog program SAPFP50P, which is already running to change the first infotype.
In my tests, afterwards screens were messed up and program stopped with different error messages.
I did following workaround:
- call perform in customer program from dynamic action to do the calculations
- when back from customer program to dynamic aciton do the infotype modification with data in structure RP50D
dynamic action look like this:
F   FORM_1(Z_CUSTOMERPROG)
P   RP50D-FLAG1='X'
I   DEL,0019,(RP50D-DATE2),,(RP50D-DATE1)/D
hope this helps

Use separate Apple IDs for each family member and use Family Sharing features of those things (if any) that you do want to share. https://www.apple.com/ios/whats-new/family-sharing/

Are you saying that you bought the game from the App store and made another copy onto a dvd so you can play it on another computer too? If so, you can not do that, you have to buy it again for the other computer.
