Calling a java application in windows enviroment from a browser

so for example first you install my java application.
Then you surf to www.example.com and the page on that site calls my application installed on windows. Is this possible?
thanks

Yes. With Webstart, you can create a link that'll run a Webstart-distributed app when clicked. "Autoclicking" this link using Javascript should be easy.

Call a Java Application from MicroFocus COBOL (in UNIX environment)

Hello,
Could you please let me know, how to call a Java application from a MicroFocus COBOL application. If anyone has any code samples, that would be of great help.
Thanks in advance,
Tijo.

You generally can't cause a program to be executed on a different >server. Basic security, you know. Besides this idea of having the Java >application run on a different server wasn't mentioned in your original >post. That leads me to believe we don't have the whole story.So I think you need to step back and find out what are the requirements. For example: Does your program need to start this Java application running, or is it already running and your program needs to connect to it somehow?
My program has to start a Java class file, meaning that the Micro Focus COBOL module will call the Java class file. Will it be running on the same machine as your program, or on some other machine?
For both cases, I would like to know the answer.a) Running on the same machine as my program is running.
b) Running on the different machine.
And then there are the questions about whether your program needs to have a conversation with the Java application, or whether it just needs to start it and that's all.
COBOL program has to call a Java class by passing some parameters and Java class in turn process it and return some value back.. Kind of Request and Response model.Plenty of questions to be asked. Go and find out what they are.
Sorry ... if I am not clear on my questions. Anyhow, thank you very much for providing the information.

Calling a java application from j2ee web application

Hi,
I have a j2ee application in which i am making a call to a jar file which is a java application.
Runtime a4 = Runtime.getRuntime();
Runtime a = Runtime.getRuntime();
String cmd[] = new String[14];
cmd[0] = "cmd";
cmd[1] = "/c";
cmd[2] = "start";
cmd[3] = "javaw";
cmd[4] = "-jar";
cmd[5] = CATALINA_HOME+"\\webapps\\AveksaTesting\\AveksaTestingJava\\dist\\AveksaTestingJava.jar";
cmd[6] = SERVER_TESTS;
cmd[7] = COLLECTOR_TESTS;
cmd[8] = SYSTEM_TESTS;
cmd[9] = CREATE_ORACLE;
cmd[10] = DB_NAME;
cmd[11] = DB_DUMP;
cmd[12] = email;
cmd[13] = isMIGRATE;
try{
java.lang.Process p = a.exec(cmd);
Now in the called java application, i am first shutting down the tomcat server by calling shutdown.bat script and then starting it using startup.bat. But the problem i am facing is when i restart the server from java application, it says address already in use(i.e. port 8445 on which tomcat is runninng).
Id i just call the java application and do the same operation it works fine. I guess when i am calling java from j2ee application, j2ee still has some threads holding java and not shutting down tomcat properly.
Can anyone suggest me what can be done in this case. I have to call a java application from j2ee and restart the tomcat server many times.
Thanks in advance

How to call java application in Windows NT environment?

I have a JDBC application running against oracle database on NT server. There is another non-java application need to call my java application. The programs that non-java program can call are .exe, .dll, and .bat files. I wrote a Dos script and save it as .bat file. Every time this .bat file was called, the dos screen will be shown. Anything I can do to let Dos screen not shown, or anything I can do to wrap my java classes into an .exe file? Thanks in advance.

If your tool can run a .exe and supply arguments, why not simply invoke "javaw <jvm-args> <class> <class-args>"?

Developing Java application for windows CE based Handheld device

Hi everybody,
I am planning to develop the java application for windows CE
based handheld device.I came to know that Oracle 9iLite supports
the Developement of Java Application for windows CE devices.Can
i use the JDeveloper IDE to develop the application on windows
NT.If so how to deploy the application on windows CE device(Is
there any options in Jdeveloper to deploy the application).Any
body please give the solution.
Regards,
Siva mani kumar.D

I agree. In my opinion Sun has done a horrible job documenting all this madness for the average developer just starting out with this stuff. There is the CLDC, J2ME, Personal Java, J2ME-WTK, MIDP, MIDP-FCS ... maddness. Anyway after sorting through it all for a few days, I think the answer to your question you will need to use Personal Java for WinCE and the Sharp Zaurus, and MIDP for PalmOS for the palm. Jeode seems to be the most common and best Personal Java implementation and it is basically the JDK1.2.2 (or is it 1.1.8) that is designed to run on WinCE and Embeddix (such as Lineo on the Zaurus). You program it just like you would a 1.1.8 application and then you can test it by running pjava.exe which is included in the personal java 3.1 download from Sun. There is also a program called JavaCheck that will ensure that your app will run properly in PersonalJava. As for the Palm, MIDP for PalmOS is a 574K program that installs on your palm device. You then use the J2ME-WTK (wireless toolkit) to build a JAR/JAD file and you use the MIDP API to write the code.

Running a Java Application in Windows

Hi, Can anyone tell me how to run a Java Application in Windows? I've tried to run it using TextPad 4.5 but it gives me an exception saying it can't find a class defenition. I'm actually using IBM VisualAge for Java to develop the app and it runs fine INSIDE VisualAge and I've exported my compiled class files and so on, to run it stand-alone in Windows. I'm using some custom objects and inner classes, could these be the problem?

YES! SUCCESS! I exported my class files from VAJ and along with the manifest file that it adds automatically. I opened up the jar with Winrar, extracted the manifest file and added the Main-class: header pointing to my executable and then put it back in the jar with winrar. And PRESTO! I can now run it with javaw! Thanks for your help peeps...

Developing Java Applications for Windows CE

Hello,
I hope this sub forum is right. So I must develop a Java Application for Windows CE. I read something about J2ME, but I think this is only for Mobilephone and Windows CE supports AWT. So I tried just some simple forms with J2ME.
Can anybody tell me how I develop java Applications for Windows CE? Can I use Eclipse or must I use another IDE?
Realy I developed Swing 5-6 Month but I have no idea how I develop Java Applications for Windows CE.
Thanks a lot for helping...

The MIDP for Palm OS 1.0 requires Palm OS v3.5 or higher to run. According to your error message, the emulator is not running v3.5 or higher. Try to get hold of a ROM image with a later version. I've run it with v4.0 of the OS and it works.

Calling Webdynpro Java Application from Webdynpro ABAP Application.

Hi,
We have developed one Application using Webdynpro Java and I m in need to call the Webdynpro Java application from Webdynpro ABAP.
Require Suggestions to acheive this.
Thanks In advance.
Reg,
Ajay.

Dear Ajay,
Assuming that both your applications WDA & WDJ are in the portal & you don't have to pass any parameters to the WDJ application.
Write the following code on the action where you would call the WDJ application.
DATA:
        lr_compcontroller TYPE REF TO ig_componentcontroller,
        l_component TYPE REF TO if_wd_component ,
        lr_port_manager TYPE REF TO if_wd_portal_integration ,
        wa_navigation TYPE navigation.
lr_compcontroller =   wd_this->get_componentcontroller_ctr( ).
l_component = lr_compcontroller->wd_get_api( ).
lr_port_manager = l_component->get_portal_manager( ) .
* The value inserted into the navigation-target field can be found in the Portal
* content administration tab of your portal. It is the ID or PCD Location field
wa_navigation-target = pcd. " Please provide the PCD Location of the WDJ Application here.
wa_navigation-mode   = '0'. "0 = INTERNAL(same page) and 1 = EXTERNAL(new page).
CALL METHOD lr_port_manager->navigate_absolute
    EXPORTING
      navigation_target = wa_navigation-target
      navigation_mode   = wa_navigation-mode.
You can get the PCD from the Page properties of the WDJ application page in the Portal.
Hope it helps!
Warm regards,
Upendra Agrawal

Help with calling a java application from inside another one

Hello!
I am having this problem which is getting on my nerves and dont know how to solve..
I want to call from my java application, another java application. So i use the exec command. Then i want to read the output of this execution from my own application, (the "parent" process).
But it doesn work properly. Something seems to happen and i dont get the whole output.
The java program i want to call is created for running an application created with Matlab java builder.
This program works when called from cmd, but seems not to work when called from inside a java application.
The code of my java application is:
Runtime rt = Runtime.getRuntime();
Process child;
// The java class getmagic is a special kind of java file that uses classes that work in matlab. It uses a component (.jar) file that is created from matlab java builder. thats why it wants the -classpath and the rest options.
//I hope you wont get messed up in here.
String[] callAndArgs = {"java","-classpath",".;C:\\Program Files\\MATLAB\\R2006b\\toolbox\\javabuilder\\jar\\javabuilder.jar;..\\MagicDemoComp\\magicsquare\\distrib\\magicsquare.jar -Djava.library.path=C:\\Program Files\\MATLAB\\R2006b\\bin\\win32;","getmagic","4"};
try{
child = rt.exec(callAndArgs);
InputStream is = child.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line;
while ((line = br.readLine()) != null)
System.out.println(line);
is.close();
System.out.println(child.waitFor());
System.out.println("Finished");
}catch(IOException e) {
System.err.println("IOException starting process!");
}catch(InterruptedException e) {
System.err.println("InterruptedException starting process!");
The java program (getmagic) thats uses matlab gives the following output (after some time) when called in cmd with argument 4
Magic square of order 4
16 2 3 13
5 11 10 8
9 7 6 12
4 14 15 1
My program shown above only prints:
Magic square of order 4
1
Finished.
Do i do something wrong? How can i get the rest of the output???
Thank you very much in advance,
Stacey
PS: I am sorry for the length of my post.

Hello CaptainMorgan08, thanx for the instant reply.
I tried, but no, i cant.
Because i cannot include this java aplication that uses matlab into my application, cause 1) it needs special arguments in the compiler and during execution so it can be run and 2) it uses classes that java doesnt have. only the java-like matlab code.
For example it uses:
import com.mathworks.toolbox.javabuilder.*;
import magicsquare.*; //the component which is made from matlab java builder.
So i cannot compile it with my application!
If you know of a way, please let me know!
I know i might be missing something.. something that is obvious to you.. but i ve been working days=nights hardly no sleep..so you can excuse me if i say something foolish..

Calling a java application from within another class

I have written a working java application that accepts command line parameters through public static void main(String[] args) {} method.
I'm using webMethods and I need to call myapplication from within a java class created in webMethods.
I know I have to extend my application class within the webMethods class but I do not understand how to pass the parameters.
What would the syntax look like?
Thanks in advance!

why do you want to call the second class by its main method ??
Why not have another static method with a meaningfull name and well defined parameters ?
main is used by the jvm as an entry point in your app. it is not really meant for two java applications to communicate with each other but main and the code is not really readable.
Have a look at his sample
double myBalance = Account.getBalance(myAccountId);
here Account is a class with a static method getBalance which return the balance of the account id you passed.
and now see this one, here Account has a main method which is implemented to call getBalance.
String[] args = new String[1];
args[0] = myAccountId;
Account.main(args);
the problem with the code above is
main doesn't return anything so calling it does do much good. two the code is highly unreadable because no one know what does the main do... unlike the sample before this one where the function name getBalance clearly told what is the function doing without any additional comments.
hope this helps.... let me know if you need any additional help.
regards,
Abhishek.

How to call a java application in a jar which is in a war file of a ear ?

So sorry to cross post, but no response in other topics.....
Please help!
I have a Ear file which contains a war file.
xx.ear/META-INF
xx.ear/YY.war
and the YY.war has the following structure:
YY.war/META-INF
YY.war/WEB-INF
YY.war/WEB-INF/classes
YY.war/WEB-INF/classes/com/
YY.war/WEB-INF/classes/com/mycompany/
YY.war/WEB-INF/classes/com/mycompany/MyClass.class
MyClass.class is a java application which has a main method.
how can I call this MyClass applicaiton from the xx.ear??
java -???? com.mycompany.MyClass ??
Please help because I have a Unix cron job need to access this class externally outside AppServer. Thx!!

an ear file is a standard jar with a different extension. You may
be able to get away with just adding a manifest file to it that
specifies the main class (make it an executable jar with a different
extension).
I don't know if this will handle the nested war file though. It may.

How to Run a Hello World Java application on WIndows Mobile

Hi!
We have a sample Plug-in environment Java application downloaded from http://www-128.ibm.com/developerworks/library/os-ecl-ercp/index.html - IBM library.
We have downloaded the source files org.eclipse.testworkbenchapp_1.0.0.jar and tried running the application on desktop PC, this worked fine.
We are using Eclipse 3.2 to run this Java application on Desktop.
Now, we are trying to run the same application on Intermec Windows Mobile 5.0 device.
1. The device has IBM J9 ? WebSphere MicroEnvironment MIDP 2.0 for Windows Mobile2003 installed in it.
2. On installing this on Windows Mobile, in Start ? Programs ? we find MIDlet HQ - on launching this, opens a window with Install button.
3. On Click on Install button, another window opens which asks for URL to install.
4. In the URL Edit box, I give file:////Org.Eclipse.testWorkbenchapp.feature_1.0.0.jar which is present in \MyDocuments\Update site folder copied from desktop workspace via Active sync ? As mentioned in the above IBM library site.
5. I have also tried file:////MyDocuments\Updatesite\Org.Eclipse.testWorkbenchapp.feature_1.0.0.jar as input to URL.
6. On click OK, I get an error titled AMS Error with description The application descriptor was missing the required MIDlet Name field.
I am held up here and not able to move further.
As mentioned in the above IBM library site I tried downloading the update site folder via Eclipse ? Software Updates ? Find and Install in Help menu.
I selected Search for new features to install and browsed the Update site folder location present in my Eclipse workspace. This also does not work.
Any help in this regard in greatly appreciated. Thanks in advance!

I would ask such questions in the J2ME forums, or even better in a websphere forum, like here:

To launch a java application in Windows environment

hello,
I need to distribute one stand alone application, that I made using NetBeans, for sale it.
I know that this is not a so simple problem, because delivering the program to one client you cannot simlpy say him to launch the jar file....
I saw that, in the Windows environment, program like eclipse or netBeans run thruogth an .exe file, that I think is a program that its purpose is to define the java environment for the application in the particular host operative environment .
Perhaps they are corporations like InstallShield (now Macrovision) that sale programs to solve this type of problems..., and I already used this type of programs to install some my
applications that I coded in languages different than java.
But before to look for one of them, I should like have more informations how this problem fits in java language, knowing that java is different to other languages because use JRE and have proper tools, how JWS and JNPL, that concern with this problem.
...Looking in the forum I had not much help..., but I saw that someone uses to write launchers program in different language, like C, as well I had not so much detailled instructions about how to do it.
In order to solve my problem I should like have, from some one that already made it, some general information about how he realized the commercial installation of java applications in the most used Operatve Systems (particullary Windows), and possibly to have links to web sites for good explanations, including advantages to buy apposite commercials installation programs too.
thank you very much
tonyMrsangelo

You can distribute it as an executable JAR so users will run it by double clicking. The would be required to have JRE installed.
You can distribute it online via WebStart. Users need JRE but it's easier to manage updates and distribution of new versions.
You can distribute it with AjaxSwing, a product that deploys Swing applications as AJAX websites so you don't need JRE at all.
You can create EXE files using many of the products available. Google for it and you'll get lots of hits.
