Using java to run another application

How to use java code to execute another program such as MS Word and etc? and how to locate the java running program into the right side windows?
Thanks

It woulds to me like you would like to do some OLE, and have the product open up into your application like it does in C/C++, VB, or J++ applications. If this is the case I would as: do you know how to do this using C/C++? I ask this because the only way I know of to do what you ask for is with a lot of C/C++ code using the OLE interface for the products you would like to incorporate.

Run another application

hello peepz...
i was wondering if it is possible to run another application when the user open another. what i mean is when user open applicationA, it will automatically run applicationB. The reason why i need this is because i want to use applicationB as a database engine to poll data from a device but i cannot combine applicationA and applicationB together in one application because when i run the engine, the program just hang.
so would appreciate it if someone show me how i could do that...
thanx
farah k.

As in
MainClassOfApplicationB.main(someArgumentArray);?^
The question is: is "running" it all you want to do or do you want those parts to actually communicate?

How to run another application in the project?

Well, the title says it all really. I created a new
application within my existing project but I can't get it to run as
it always runs my main application (which has a little blue sphere
on its icon).
How can I get the other application to test and/or
run?

Managing launch configurations
Launch configurations are used both to run and to debug
applications. Flex Builder provides a default launch configuration
for Flex and ActionScript applications. When you first run or debug
a project, a project-specific launch
configuration is created. You edit the launch configuration
to change the default main application file. You can also
modify the default launch path to run or debug in the
stand-alone Flash Player rather than in a web browser.
Creating or editing a launch configuration
When you create and build a project, it is ready to be run or
debugged. Both running and debugging of the applica-
tions in your project are controlled by a launch
configuration. By default, Flex Builder creates a launch
configuration for each of the application files in your project the
first time you run or debug them. The configurations are based on
the default Flex application configuration, and you can edit them
as necessary.
Launch configurations are managed in the Create, Manage, and
Run Configurations dialog box.

What the use if u run in application server

hi friends,
at info pakcage level we can use client server and application server, for process chain we are using application server. what is the use if we run in the back ground process.
Thanking u
suneel.

hi Suneel,
i think you mean for flat file upload,
for flat file upload there are options for the file in application server or in client side, and to run infopackage there is option background,
if we choose background process, we have to use option 'application server',
means the file must be put in server side
hope this helps.

How to use java output with other application

hi ,
I am using acme.crypto to encrypt data. this is completely written in java. i need to pass input to this using VB6 and return the output to VB6
how can i achieve the same, is there any readily available dll that can be used in vb?
I am rigorously searching solution, which i am not finding.
I need to know how should i place the java code so that it could be used with VB, as i am new to java world. Do i need to create component using java bean or how?
The code i refered above is nothing but encryption algorithm. I need to pass the input string from vb to java, which will process me the output which inturn should be passed to vb6.
Kindly guide me through this.

Why not create a Java ServerSocket in your Java program.
Connect the VB program to this ServerSocket.
Send the input to the Java Program over this socket and have the Java Program encrypt the information and pass it back on the same socket.
Don't know how hard Sockets are in VB6 but a Server Socket in Java is simple.
No need for new DLLs, JNI, etc.

Use java to run a shell script which called a crontab command at Unix

I was trying to write an automate function using Java, which needs to call a shell script containing a crontab commend. The shell works fine without that crontab commend, but once I add it, the program won't execute that crontab commend.
public void cron(){
try
Process proc = Runtime.getRuntime().exec("script1");
BufferedReader br = new BufferedReader(new InputStreamReader(proc.getInputStream()));
String line;
while ((line = br.readLine()) != null)
System.out.println(line);
int returnValue = proc.waitFor();
br.close();
} catch (Exception e){} //
script1:
#!/bin/sh
crontab cronfile
Can someone help me out for this? Thank you.

Try this....
Process p = Runtime.getRuntime().exec("sh");
java.io.BufferedWriter bw = new java.io.BufferedWriter(new java.io.OutputStreamWriter(p.getOutputStream()));
bw.write("script1");
bw.flush();
bw.close();

Using Java Applet in WebDynpro Application

Hello,
I have the problem that I must access the client in my WebDynpro Application.
But I found no way to include a Java Applet in my application, so my question: Is it generally possible to include a Java Applet or not?
If it is not possible with an Applet, is there any other way to access the client?
Thanks a lot

We actually embed Java applets in our application. But only on the portal.
Wrap the applet around a BSP.
Call the URL in an iframe.
To prevent the reloading problems that we see with applets and actions, we put the applet in a modal window, with an OK button at the bottom so that when applet processing is finished, the rest of the web dynpro functionality resumes.
If you need to have them both in the same page, you can embed the BSP iview in the same portal page.

Using an Applet to run another application

To anyone that can help.
Simply, can I have an applet that runs an PC application?
More detail:
I am relatively new to the Java Development environment, but so far have put together a reasonable intranet web application that takes user input and writes to an Oracle database. From this information, I have then invoked Microsoft Word and populated a template with information to create a document.
All fine and good, but I am running everything under W2000 so I have server and client all in the one place. I am using Tomcat 4 as my server, the application is written using JSP and my own Beans.
The principle of how the Word link works is: within the JSP information is written to a Bean, which creates a file and then executes a WordAPI using:
cmd = "WordAPI.exe";
try {
Runtime.getRuntime().exec(cmd);
This is OK with everything on one machine, but I now need to set it up on a server and this will not invoke Word on the client. I thought that if I turned the bean into an applet then it would run at the client end and that would resolve the problem, but it doesn't work. Am I breaking some rules or trying to do the impossible?
Thanks for any help

I think it boils down to a matter of security. An applet generally runs in what is known as a sandbox. Since you're talking about an intranet and you didn't say anything about Netscape browser, I'll assume that you're only interested in IE. In IE, you can start by testing to see if your application will work if you click:
Tools-->Internet Options-->Security-->Trusted sites-->sites
and add the intranet URL to make it a trusted site.
If that doesn't work, you may have to sign the applet and put it in a .cab file. To do this you'll need to use the cabarc command (if you can't find the command on your system, search www.microsoft.com web site for a download). After having signed the applet, you still have to make sure that the client's IE security settings are just right for what you needed to do. For this, you'll have to look at:
Tools-->Internet Options-->Security-->Local intranet-->Custom Levels...
Good Luck!

The trouble is although this script works great for commands that can be run is the 'background' as SYSTEM is I want to pass a command to actually open something e.g. notepad in the above example nothing seems to happen. As far as I can make out the command line is running but not as %username% so it's not running notepad.exe in the foreground.
I'm happy to clarify more if necessary.
Can anyone help with this?
Cheers

Bill,
Thank you for the quick answer. I believe you are right in your assumption.
I have been searching but found nothing so far.
I need to be able to run this line "wmic
Product where name='XXX XXX XXX' call uninstall"
in an elevated command prompt to uninstall the program.
I was looking for a VB script or PowerShell to execute it remotely on non domain roaming PCs.
Th3e command can be run remotely against stand-alone workstations but you must supply credentials. Post in the platform forum for you version of Windows for help in using the WMIC utility. WMIC /? will give you all of the command options fro
remote execution. UAC only affects local systems. You cannot use WMIC to remote back to the local system. WMIC does not allow impersonation to the local system.
Most installers will not automatically allow an unattended uninstall. If there is any dialog at all the uninstall will fail and can hang.
I recommend contacting the vendor of the application to get more information.
In all cases you cannot bypass UAC as Bill has noted. I am only noting that, sometimes, in a workgroup, you can use WMIC to remotely uninstall an application.
¯\_(ツ)_/¯

Calling a java webservice from another application say a Vb client

Hi,
I have written a simple web service which greets the user "Hello" and using Apache axis and deployed on Tomcat.Everything works fine.
But lots being said about interoperability but right now i cannot appreciate that as i don't know how to call my webservice written in java to be called from say a VB application or a component running on IIS server.
Can anyone write a small snippet of code to do that..
Your help is highly appreciated...
thanks

Thanks!

The file is saved as the class name.
Here's what happens:

Using BroadcastSystemMessage to ping another application

I have a server application from a vendor that provides various services I need to use. The vendor also provided a sample client application written in Borland C++ Builder. I'm trying to implement the same message passing scheme they use in their client ina CVI program, but I can't get past the first step.
The Borland app first uses BroadcastSystemMessage to ping their server application. Then it waits for a response from the server in the form of a WM_COPYDATA windows message. The original Borland code for pinging the server looks something like this:
   UINT ping_id = RegisterWindowMessage("client_ping");
   DWORD dwApps = BSM_APPLICATIONS;
   BroadcastSystemMessage( BSF_NOHANG, &dwApps, ping_id, (WPARAM) m_client_handle, 0 );
The m_client_handle is the windows handle of the client application. The server uses that handle to send it's reponse directly back to the client. My CVI implementation of the ping looks like this:
    GetPanelAttribute (panelHandle, ATTR_SYSTEM_WINDOW_HANDLE, (int *)&ClientWindowHandle);
    int PingId = RegisterWindowMessage("client_ping");
    DWORD dwApps = BSM_APPLICATIONS;
    int err = BroadcastSystemMessage(BSF_NOHANG, &dwApps, PingId, (WPARAM) ClientWindowHandle, 0);
BroadcastSystemMessage returns a 1 indicating that everything worked fine.
The next half of the ping is to catch the return message from the server. The Borland app does this by implementing the call OnCopyData for it's main form. As best as I can determine, this is essentially a predefined message handler for WM_COPYDATA. I implemented this in CVI with the following code:
int main (int argc, char *argv[])
    // this is really the same call as before (i.e., I only get the handle once)
    GetPanelAttribute (panelHandle, ATTR_SYSTEM_WINDOW_HANDLE, (int *)&ClientWindowHandle);
    InstallWinMsgCallback (panelHandle, WM_COPYDATA, ProcessWmCopydataMessage, VAL_MODE_INTERCEPT, &panelHandle, &ClientWindowHandle);
int CVICALLBACK ProcessWmCopydataMessage (int panelHandle, int message, unsigned int* wParam, unsigned int* lParam, void* callbackData)
    PCOPYDATASTRUCT ServerInfo;
    if (message == WM_COPYDATA)
        // process returned message
The problem is that I never get a call to PrcoessWmCopydataMessage. Am I doing something wrong in my setup? In particular, am I retrieving the correct handle for my application and am I sending it correctly in the broadcast message? Is there any spy tool that allows you to watch all windows messages and reponses so I can determine if the server is doing anything?
I tired writing my own dummy server just to verify that BroadcastSystemMessage works the way I expect. The only problem is that I can't figure out how to catch the broadcast message in my dummy server app. How do I install a callback that will catch broadcast messages?
One last thing: at first I couldn't get BroadcastServerMessage to compile. It said it was not declared. After a quick search on the forum, I added the following line before my inclusion of the windows header:
    #define _WIN32_WINDOWS 0x0410
It compiles now, but I'm concerned that by faking my Windows version I may have messed up something else. I running Windows 7 BTW.
Tony G.

Hey Tony -
The reason you get the compile error is because CVI does not define _WIN32_WINNT in the version of CVI you are using. We expect the programmer to define it based on their own needs. BroadcastSystemMessage is conditionally compiled so that it will not be defined if _WIN32_WINNT is not defined:
WinUser.h
#if defined(_WIN32_WINNT)
WINUSERAPI
long
WINAPI
BroadcastSystemMessageA(
The consequence of defining it to be 0x0410 is that you are stating your program is compatible with version NT 4.0 of Windows and later. This means that you can use all functionality of the Windows OS that was available in Windows NT 4.0, but none of the newer functionality will be available to you. If you try to run your program on a version of Windows older than Windows NT 4.0, the program will likely not run (this should not be an issue...)
Note that 0x0410 is not actually a defined Windows version. From a recent version of the Interface to the Win32 API, you can read from sdkddkver.h:
#define _WIN32_WINNT_NT4     0x0400
#define _WIN32_WINNT_WIN2K   0x0500
This means that you are stating your program uses no Windows fuctionality more recent than Windows NT 4.0. Here's some more good information on using these macros.
