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.

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.

How to call a WD4A Application of another system

Hi,
I have the need to call a WebDynpro Application of another system via a URL call, thet the application should be opend in the CRM WebUI Window (statefull ) .
Calling the application via a button event & transaction launcher works fine, but i need to call it from a BSP page. So my idea was to create an iframe, but this obviously opens a new window:
<html>
<head>
    <title>IFrames - Webdynpro Test</title>
</head>
<body>
    <iframe src=<%= lv_url_route %>"
      width="100%" height="500" scrolling="auto" frameborder="1" transparency>
          </iframe>
</body>
<html>
Can anybody help?!?!
Thanx & best regards,

      lr_viewer       type ref to cl_gui_html_viewer.
data: lv_url(200)     type c.

    exceptions
      cntl_error         = 1
      cntl_install_error = 2
      dp_install_error   = 3
      dp_error           = 4
      others             = 5.

How to call a Java class from another java class ??

Hi ..... can somebody plz tell me
How to call a Java Class from another Java Class assuming both in the same Package??
I want to call the entire Java Class (not any specific method only........I want all the functionalities of that class)
Please provide me some slotuions!!
Waiting for some fast replies!!
Regards
Smita Mohanty

Hi Smita,
you just need to create an object of that class,thats it. Then you will be able to execute each and every method.
e.g.
you have developed A.java and B.java, both are in same package.
in implementaion of B.java
class B
            A obj = new A();
             //to access A's methods
             A.method();
            // to access A's variable
            //either
           A.variable= value.
           //or
           A.setvariable() or A.getvariable()

How to make a Java application that will change the client box's IP address

If you can do that through the command line, then use Runtime.getRuntime().exec(...) to execute your command.

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

GOT IT !!!
I had to change the name of the method in .h file generated by javah command. On doing
javac -d ../../classes HelloWorld.java
go to the ../../classes directory (where you have the class file) and do
javah HelloWorld
I got a HelloWorld.h file in which I had
JNIEXPORT void JNICALL Java_HelloWorld_display(JNIEnv *, jobject);
I added the package name too:
JNIEXPORT void JNICALL Java_GUI_HelloWorld_display(JNIEnv *, jobject);
The HelloWorldImp.c file should have the same name (ie with package) and be in the same directory(ie ../../classes)
compile and build the shared library to get "libhello.so" file
gcc -c -fPIC -I/usr/lib/j2sdk1.3/include -I/usr/lib/j2sdk1.3/include/linux HelloWorldImp.c
gives .o file
gcc -shared -o libhello.so HelloWorldImp.o
gives .so file
then run java with the command in my first message. It works.
Thanks for the reply "thedracle".

How to call custom BSP application (copied from standard)

Hi,
I came across 1 interesting link in SDN.
[Enhancement procedure of BSP application HRRCF_RECRUITER in eRecruitment]
My requirement is also similar.
I need to copy the HRRCF_TRM_SRCH application.
I know how to make the changes for the logic (like copying the standard controller & iterator class etc.)
But I donu2019t know how to call the custom BSP application.
One requirement is, I need to call a BSP application, in which there are only UI(user interface/screen) changes .
That is, if there are only changes made to hitlist_cand.bsp page . And no changes made to hitlist_cand.do page.
Eg: Removing one button from screen.
Second requirement is, I need to call a BSP application in which there are logic changes also.
(I know how to change the standard controller class to custom class)
Eg: Changing logic of button.
We tried renaming the application name from standard to custom one (with Namespace=SAP itself, though it gave a warning) in the table T77RCF_LOG_APPL .
Then we used this name to configure the start page link. But still the execution control is going to standard page & not to custom BSP application.
How will I know which BSP application(Appl A), is calling the BSP application (Appl B) in which I want to make changes ?
The starting application is HRRCF_START_INT.
Would really appreciate solutions posted.
Thanks,
Nisha Vengal.

Hi Nisha,
I think you have an issue to call custom BSP.
- Ignore the warning message (in the table T77RCF_LOG_APPL) as it is just a warning message. I did not touch start page link at all.
- Additionally you need to make (I had to made) an entry in table u2018V77RCF_SMG_NAVIu2019.
Let me know, if you need anything else.

How to call a struts application in a portlet

How to call a struts application in a portlet. I have two different ear's. In one ear I have my struts application and in one war i have a struts portlet. In the struts portlet provider.xml defaultAction tag can i call the action class .do which in other ear (ie my struts application ear).Can anyone suggest me whether this is the right way or else can u suggest me with some other thing.
Waiting for ur responses.
Thanks and Regards,
Dhanu.

Hi Dhanu,
Your Struts Portlet will not be avialble via a URL as it is completely dependent on Oracle Portal Environment. The Provider for the Portlet is alone available via a URL - you would have registered your Portlet using the URL of the Provider.
Your Struts application, which does not rely on the Oracle Portal Environment, is defeitely accessible from a URL. It's just another web application that uses the popular Struts Framework.
Hence, you can use the URL ( the starting point - a JSP, Servlet, etc. ) of your Struts Application to "call" the application in your Struts Portlet. I don't think you need to fiddle with the parameters in Provider.xml.
Moreover, <defaultAction> in Provider.xml should have the URL of a Struts Action Class - the mapping in the
struts-config.xml should map the .do action to the right JSP file.
You can have a look at Metalink Note : 331069.1 for a good insight into the <defaultAction> Tag.

Sandeep

How to start a java application by double clicking just like windows gui?

Hi,
I want to open the user-defined file in my java application. The way is like the notepad in windows:1.double click the file name 2.the file is opened in the java application 3.if this file has opened at the same time ,then the last opened will be read-only.
Could you tell me how to carry it out ? Thank you
from Maria

!!! Please give me a help! i am thirsty for itSo, to get this straight, you have a Java application in a jar. For some reason, you do not execute this directly. Are you aware that you can execute a jar directly without the need to write a C++ exe to do it?
Anyway, for some reason, instead you have a C++ application which launches the JVM with your jar main class.
Well, you want to do two things. First of all, on Windows level, you need to associate the file type of your user file with your application. Note that they have to have a specific file extension that you choose. To associate the file type with an executable, you open a windows explorer, go to View, Folder Options, File Types and add an entry for your file type and specify it to open with your application. If you do not know how to do this, google for "windows associate file type with program executable" or something alike.
Now, if you double-click one of your user files, the associated exe will open, and it will receive the file name as a command line argument. In your C++ application, you will need to pass this argument, a file name, to the Java application where you launch it.

How to schedule a java application via Windows Scheduler

I can't figure out how to schedule a java application using the Windows Scheduler. Do I schedule the java application with the .class file as a parameter? How do I pass arguments to it?
To execute FileCopy.class, my best guess was:
Start | Control Panel | Performance and Maintenance | Scheduled
Tasks | Add Scheduled Task | Browse | Program Files | Java |
jre1.5.0_06 | ... Advanced Properties
Under the Task tab:
Run: "C:\Program Files\Java\jre1.5.0_06\bin\java.exe"
Start In: "MyDocuments\Eclipse_Workspace\Java_File_Copy
FileCopy"
This does not work. How do I schedule the FileCopy.class java application, and how can I pass arguments to it? Can this be done without specifying a password?
TIA,
John

Suppose that your class is FileCopy (has no package name) and is located under MyDocuments\Eclipse_Workspace\Java_File_Copy folder, then you should have:
Run: "C:\Program Files\Java\jre1.5.0_06\bin\java.exe" FileCopy
Start In: "MyDocuments\Eclipse_Workspace\Java_File_Copy"
And yes you must provide a user password to execute the task.
Best way to do this is to create a special user (with password) for executing this task.
