Can a WAR call methods in a 'Parent' jar?

With oc4j, can I designate a jar containing ejb's (2.1) as a parent of a war file that has servlets which call methods on the ejb (via jndi lookup)? I want to accomplish this without an ear.
I am considering migrating from JBoss and for some reason JBoss let's me get away with this. This would ease migration substantially.
Thank you all;

I have a question here..
Will reconfiguring iAS to use J2SE 1.4 conflict with Oracle Portal (9.0.4). I mean we have everything running smooth for Portal so we want to make sure that reconfiguring iAS for J2SE 1.4 won't have any affect on Portal.
I hope you can reply me on this or refer me to some other document.
Thanks in advance.

Can we use call method or call action in dynpro.

hi all,
In the view of a web-dynpro, can we call one action inside another action..?
or can we call a method inside an action..
if so plz help...
thanks in advance,
jithin.

Hi Jithin,
Suggest you that, you keep your logic in a method which you are using for create(event).
the same method you can call in modifyview so that after you create again the modifyview will get trigger and then it fills your dropdown.
or
after create functionality is done then call a method to fill the dropdown.
try to modularize your code using methods then you can
re-use it.
still you need any clarificatinos let me know.

Calling method from SWF file wtih javascript, when swf file is not loaded in any browser

Hi There,
I have a question regarding flex and javascript integration:
1. We have created certain components and bundle them in swf. these swf file uses webservice to connect to backend code written in java.
2. We have deployed swf file and backend on the same tomcat server.
3. Backend server send some datapoint to UI and plot graph and displyaed to user.
4. Now if user generate graph from datapoint and want to export it, we are tranferring image of that graph from UI to backend. No issues in this process.
5. Now the question is. let say user has not open any swf file in browser and backend scheduling job want to generate the graph. How we will connect to swf file.
6. Is ther any way we can connect or call method of swf from java/jsp/html/javascript code in this scenario without loading swf file in browser??
Please help me!!!
Thanks
Sonu Kumar

Both test sites work just fine for me.
The "Update plugin" message is exactly what would be displayed if no .swfobject file at all was found... so it may not be the "version11" thing but rather, perhaps something else is messed up with the .swfobject file.
File can be found in both folders:
http://www.pureimaginationcakes.com/test/Scripts/swfobject_modified.js
http://www.pureimaginationcakes.com/Scripts/swfobject_modified.js
and file does download when downloading the html page (just check the cache).... but for some reason it doesn't seem to be working.... Hummmmm????

How to retrieve the calling method

Hi all,
Is there anyway I can get the calling method from the method I am currently in e.g.:
thisclass..setup().getText()
and in getText can I check to see which method has called it?
Thanks in advance.

You can extend SecurityManager to get an array containing the class context (just the calling class, not the calling method), or you can create a Throwable and get an array containing a trace of the stack.

How to call a custom method in a parent container.

I have an MXML component that defines the method:
public function showAllGlyphs(spots:Array):void { ... }
There is a child component of this MXML componet called
DataClip, which has
a method that needs to call the parent method:
parent.showAllGlyphs(pushPins);
I get a 1061 error when compiling. I understand the problem.
The compiler
thinks the paret is a static class, and does not know about
the extention.
My question is how to I cast or otherwise reference this
method in the
PARENT?
Severity Description Resource In Folder Location Creation
Time Id
2 1061: Call to a possibly undefined method showAllGlyphs
through a
reference with static type
flash.display:DisplayObjectContainer.

I understand why what you say is the correct design pattern
(much more
modularity and the potential for re-use).
In my case, it still might make sense to use .parentDocument
(my problem was
not understanding the difference between .parent and
.parentDocument)
Although I still don't understand why .parentDocument does
work.
I have a bunch of purely GUI oriented subComponents of a
.parentApplication.
The parentApplication has a custom AS-only module that does
the "business
logic, network connections, etc).
Basically, I want a module (Singleton Class) that is
accessible from all GUI
subcomponents that provides general utility functions. It
can't be
instatiatiated multiple times. So there needs to be one
global place for it.
It does not really make things clear if everything is done
via an event
paradigm. (Well, maybe to me, but I have a Ph.D. in CS so I
am tainted) I
want this clear to the average programmer.

How can a custom class call a function in "parent" class?

Say I have an application (ultrasimplified):
public class myApp {
myClass mc;
boolean foo=false;
public static void main(String[] args) {
mc = new myClass();
public static void myFunc(boolean blah) {
foo=blah;
in a separate .java file where my questions lie:
public class myClass {
boolean bar=true;
public void myClass() {
// this is wrong, but how would I do this:
foo = bar; // foo in myApp set to true
// or how would I call "myFunc()" in myApp from this class:
myFunc(bar);
my problem is that I've created a new class that I share between two applications so I could share the code. However, I want this class I created to call a function in the application class that instanciated it. Or alternatively, I would like to set a variable in the class that instanciated myClass.
How would go about this? I've used the "this" parameter in applets to pass the parent class to an inner class, but main() in applications doesn't allow the non-static "this":
myClass my = new myClass(this);
Is there something similar I can do?

You can let MyApp implement an interface and refer to that object in MyClass:
class MyApp implements Something {
main() {
MyApp app = new MyApp();
MyClass mc = new MyClass(app);
public void foo() { }
class MyClass {
Something app;
MyClass(Something app) {
this.app = app;
app.foo();
interface Something {
public void foo();
Better yet, you can let MyApp extend an abstract class that defines foo(). Then MyApp can override the foo() method. If later on, the abstract class needs to add a bar() method then default implementation can be done in the abstract class. If you make it an interface then all implementing classes will have to be updated to implement the new method.

Can I Call method on one JVM from another through a dll?

Let me explain.
I have this java jar file that I can only have one instance of running at any given time. I'm using a shared data segment in a dll to store a bool indicating whether the program is already running or not. If it's already running, I have to not run the second instance and give focus to the current running instance.
The jar file calls a native method "canInstantiate()" on a dll to see if there's already an app running. If there isn't, the env and obj are stored in the shared data segment of the dll and we return true. If there is already an instance of the program running, I want canInstantiate call a function on the current instance of the jar (like a callback) to tell it to request focus. It's not working. Can someone tell me if my code is right?
The .h file
#include "stdafx.h"
#include <jni.h>
#include "CardServer.h"
#pragma data_seg("SHARED") // Begin the shared data segment.
static volatile bool instanceExists = false;
static JavaVM *theJavaVM = NULL;
static JNIEnv* theJavaEnv= NULL;
static jobject instanceObject = NULL;
static jmethodID mid = NULL;
static jclass cls = NULL;
#pragma data_seg()
#pragma comment(linker, "/section:SHARED,RWS")
jdouble canInstantiate(JNIEnv *env, jobject obj);
jdouble instantiate(JNIEnv *env, jobject obj);
jdouble uninstantiate(JNIEnv *env, jobject obj);
void grabFocus();
</code>
The .cpp file:
<code>
#include "MyFunctions.h"

jdouble canInstantiate(JNIEnv *env, jobject obj)

printf("No instance exists!!");
return (jdouble)0.0;
else
printf("An instance already exists!!");
grabFocus();
return (jdouble)1.0;
jdouble instantiate(JNIEnv *env, jobject obj)
printf("**In CPP: Instantiate!!\n");
cout << "At start, env is: " << env << endl;
cout << "At start, obj is: " << obj << endl;
if (instanceExists == false)
instanceExists = true;
theJavaEnv = env;
instanceObject = obj;
theJavaEnv->GetJavaVM(&theJavaVM);
cls = (theJavaEnv)->FindClass("TheMainClassOfTheJar");
if (cls == 0) {
fprintf(stderr, "Can't find Prog class\n");
exit(1);
mid = (theJavaEnv)->GetMethodID(cls, "grabFocusInJava", "(I)I");
if (mid == 0) {

grabFocus();

if (mid == 0) {
fprintf(stderr, "Can't find grabFocusInJava\n");
exit(1);
theJavaEnv->CallIntMethod(instanceObject, mid, 2);
printf("Called grabFocusInJava\n");

Can I Call method on one JVM from another through a dll
...The rest of your question merely expands on your title.
And the answer to that question is no.
When you call a method you are executing a "thread of execution." A thread of execution exists only in a single process. It can not exist in another process.
If the dll is doing some interesting things then you could call a method that sets a flag. Data can move between instances. But you would then have to have a thread in that different process monitoring that flag. And sharing data in a dll is not a normal process, so it would have to be coded appropriately.
If all you want to do is set the current focus to the existing application, then that can be done with existing windows functionality. You don't need to do anything special in your dll. You can probably search these forums to find the exact code. If not there are countless examples in windows repositories (like MSDN) on how to do that.

Can an applet call one of the methods of servlet??

hi everyone...
i m very new servlet and applet programming and i have come accross a problem....
i m using a applet which establishes connection with the servlet(residing on server)..i want to use few of the methods of the servlet....
now is it possible tfor me to call the methods of this servlet using its object.???
please help me..
thanx in advance

first of all thanx a lot for the reply...
but i wanted to know can an applet call any other
function of servlet other than get and post....as i
hacve defined some more functions in servlet..
please reply...I did this a while back (2003/4?) and unless it's changed you cannot do it directly, it must be GETor POST, then you could just use conditional logic to invoke another method.

In a call method, I can make an IMPORT?

In a call method, I can make an IMPORT?
thanks!!

You can import, export parameters using call method.
check out this example.
DATA : w_num1 type i value 5,
       w_num3 type i value 7,
       w_num4 type i.
CLASS c1 DEFINITION.
PUBLIC SECTION.
METHODS : m1
               IMPORTING num1 TYPE i
               EXPORTING num4 TYPE i
               CHANGING num3 type i.
ENDCLASS.
CLASS c1 IMPLEMENTATION.
method m1.
num3 = num3 * 2.
num4 = ( num1 + num3 ) ** 2.
endmethod.
ENDCLASS.
START-OF-SELECTION.
DATA : oref1 TYPE REF TO c1 .
CREATE OBJECT : oref1.
CALL METHOD oref1->m1 EXPORTING num1 = w_num1
                      IMPORTING num4 = w_num4
                      CHANGING num3 = w_num3.
Write:/5 w_num1 , w_num3 , w_num4 .
This might help you.

Can we hav call transaction and session method for an application

can we hav call transaction and session method for an application ?if yes how?

Hi ,
You can. If Call Transaction fails, a batch input session can be created.
Check this example-
Call the transaction. Messages from Call Transaction are stored in the
internal table messtab
CALL TRANSACTION 'LT01' USING bdc_tab MODE 'N' UPDATE 'S'
      MESSAGES INTO messtab.
IF sy-subrc = 0.
Call transaction successfull, get the number of the Transfer Order that
was created
    LOOP AT messtab.
      IF messtab-dynumb = '0104' AND messtab-msgnr = '016'.
        w_transportorderno = messtab-msgv1.
      ENDIF.
    ENDLOOP.
ELSE.
Call transaction failed, create a batch input session instead.
    PERFORM open_group.
    PERFORM bdc_insert USING 'LT01'.
    PERFORM close_group.
ENDIF.

Can we use Call transaction and session method in same program ?

Hi experts,
Is it suggested to use call Transaction and session method in the same Program ?
i have a doubt , why cant we use multiple call transactions in same program instead of session method if we have multiple transaction updations ?

Hi Dengyong Zhang,
we can use the call transation and session method in same program.
However for better performance it's benificial to use call trasaction method of BDC. but if u want to upload very large amount of data then Session method is more preferable to use.
Session method is one of the method of BDC.
U can also use BAPI to upload the data in SAP but it's a different concept than BDC. Performance wise BAPI is more advantageous than BDC.

How can i interact with the ALV if i am using the lvc_ and call method?

i want to hide the last entry of a line when i click on the checbox of my ALV

u want to hide or delete?
instead of using check box, u can use a button to display there.
it can be achived like below.
data: ls_lvclayout type lvc_s_layo.
LS_LVCLAYOUT-SEL_MODE = 'D'.
now in set_table for_first_diaplay
CALL METHOD GO_GRID->SET_TABLE_FOR_FIRST_DISPLAY
      EXPORTING
      <b> IS_LAYOUT            = LS_LVCLAYOUT</b>
do like above.
then u click on the row, and the row will be selected.
now using the method GET_SELECTED_ROWS, u can get the data of the selected row and u can now manipulate what ever u needed.
data:
SEL_ROW TYPE LVC_S_ROID,
SEL_T_ROW TYPE LVC_T_ROID.
CALL METHOD GO_GRID->GET_SELECTED_ROWS
    IMPORTING
      ET_ROW_NO = SEL_T_ROW.
LOOP AT SEL_T_ROW INTO SEL_ROW.
          read table <itab> index SEL_ROW-ROW_ID.
          check sy-subrc = 0.
< now write the logic like making the field blank and modify the itab>.
        ENDLOOP.

I have deployed SSIS Package to Integration Services Server, Can i still call them in Parent Package

i have deployed SSIS Package to Integration Services Server, Can i still call them in Parent Package

Hello,
In SSIS 2008 you have to adjust your parent package in Visual Studio and point to the deployed package, as ArthurZ stated.
In SSIS 2012 with projects in project deployment mode this has become easier: you can call the child package in your project from the main package and it will use the package in the development. then you can deploy the project ot SSISDB and the
Main package in there will call the child packages in the SSISDB.
