Calling a portal based application from another WD java application.

Dear All,
I have a requirement to Access a Portal based customised application from a WD Java appln.
Please help me .
Thanks and Regards,
Soumyadeep.

Hello Soumyadeep,
The procedure that you are using for calling the portal application is correct.
But if nothing is happening on click of the button then i think you are not running the application in the portal. You are running it as an independent web dynpro application.
If you run your application as an iview in the portal only then you can use this navigateabsolute method.
So run your application as an iview and try to navigate from there only then it will be able to fetch the url from the PCD.
otherwise get the url of that application and create a nonmodal exteranl window and give it the url of the
application.
So to use the code that you have written here you have to upload this application to the portal and then you can call that particular iview when it is called from the portal.
Hope it is clear.
Please let me know if you still have an issue.
Thanks

Calling an Portal Webdynpro iView from another Webdynpro iView - Error

Hi,
I have modified the DefaultFramework Page by adding an Alert iView (based on WebDynpro) and assigned this modified framework page to all users. It works fine.
The Alert iView on the Left hand side (right above the Detailed Navigation) consists of links to different WebDynpro iViews in the same Portal.
I have used LinkToAction UI element, on event of click
i am executing this piece of code.
onActionClick (com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent)
WDPortalNavigation.navigateAbsolute("ROLES://portal_content/folders/X.Iview", WDPortalNavigationMode.SHOW_INPLACE, (String)null, (String)null, WDPortalNavigationHistoryMode.NO_DUPLICATIONS, "Called iView Name", (String)null, (String)null);
I have picked up the iView name from the Portal(exact PCD location).
It is not working. Once in a while it worked. But now it is not loading at all.
Please let me know your thoughts on the same.
Thanks

Hi,
Got it solved. User has authorization to execute the page.Their roles were not added in Permission list of that Page.
Added the roles. Now it works fine.
Thanks

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"
#include <string.h>
#include <stdlib.h>
#include "stdafx.h"
#include <iostream.h>
jdouble canInstantiate(JNIEnv *env, jobject obj)
printf("In canInstantiate!!");
if (!instanceExists)
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) {
fprintf(stderr, "Can't find grabFocusInJava\n");
exit(1);
printf("About to call grabFocusInJava\n");
grabFocus();
printf("CPP: After the grab focus command in instantiate!!\n");
cout << "At end, env is: " << env << endl;
cout << "At end, obj is: " << obj << endl;
return 0.0;
else
printf("CPP: Finished Instantiate!!\n");
return 1.0;
jdouble uninstantiate(JNIEnv *env, jobject obj)
printf("CPP: In uninstantiate!!\n");
if (instanceExists == true)
instanceExists = false;
theJavaVM = NULL;
instanceObject = NULL;
printf("CPP: Finishing uninstantiate!!\n");
return 0.0;
else
printf("CPP: Finishing uninstantiate!!\n");
return 1.0;
void grabFocus()
printf("In CPP::GrabFocus!!\n");
instanceObject = theJavaEnv->NewGlobalRef(instanceObject);
cls = (theJavaEnv)->FindClass("CardFormatter");
if (cls == 0) {
fprintf(stderr, "Can't find Prog class\n");
exit(1);
printf("Got the cls id again!!\n");
if (cls == 0)
printf("IT'S INVALID!!\n");
mid = (theJavaEnv)->GetMethodID(cls, "grabFocusInJava", "(I)I");
if (mid == 0) {
fprintf(stderr, "Can't find grabFocusInJava\n");
exit(1);
theJavaEnv->CallIntMethod(instanceObject, mid, 2);
printf("Called grabFocusInJava\n");
</code>
thanks in advance

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.

Calling a class's method from another class

Hi, i would like to know if it's possible to call a Class's method and get it's return from another Class. This first Class doesn't extend the second. I've got a Choice on this first class and depending on what is selected, i want to draw a image on the second class witch is a Panel extended. I put the control "if" on the paint() method of the second class witch is called from the first by the repaint() (first_class.repaint()) on itemStateChanged(). Thankx 4 your help. I'm stuck with this.This program is for my postgraduation final project and i'm very late....

Calling a procedure (with refcursor) from another procedure

I have a procedure that returns refcursor (it's used by a Java application).
I am able to run the proc via SQLPlus like below:
var a refcursor;
exec MY_PKG.get_content_prc(:a);
print a;
I would like to use/call this proc from another procedure and I am not able to, since arg is refcursor.
create or replace procedure p
is
v refcursor;
begin
MY_PKG.get_content_prc(:v);
end;
Error I get is:
SQL> show err
Errors for PROCEDURE P2:
LINE/COL ERROR
4/3 PL/SQL: Item ignored
4/7 PLS-00201: identifier 'CURSOR' must be declared
6/5 PL/SQL: Statement ignored
6/57 PLS-00320: the declaration of the type of this expression is
incomplete or malformed
Hope someone can direct me.
Regards

Because you are not using the right syntax.
You need to do something like this
LOOP
   /* Fetch from cursor variable. */
   FETCH emp_cv INTO emp_rec;
   EXIT WHEN emp_cv%NOTFOUND; -- exit when last row is fetched
   -- process data record
END LOOP;This is from the PL/SQL User's Guide and Reference.
I would recommend reading this fine manual, it is faster than guessing.

Calling a TextFields get method from another class as a String

This is my first post so be kind....
I'm trying to create a login screen with Java Studio Creator. The Login.jsp has a Text Field for both the username and password. JSC automatically created get and set methods for these.
public class Login extends AbstractPageBean
private TextField usernameTF = new TextField();
public TextField getUsernameTF() {
return usernameTF;
public void setUsernameTF(TextField tf) {
this.usernameTF = tf;
private PasswordField passwordTF = new PasswordField();
public PasswordField getPasswordTF() {
return passwordTF;
public void setPasswordTF(PasswordField pf) {
this.passwordTF = pf;
My problem is in trying to call these methods from another class and return the value as a string.
Any help on this matter would be greatly appreciated.

the method returns the textfield, so you just need to get its text
import java.awt.*;
class Testing
public Testing()
    Login login = new Login();
    System.out.println(login.getUsernameTF().getText());//<----
public static void main(String[] args){new Testing();}
class Login
private TextField usernameTF = new TextField("Joe Blow");
public TextField getUsernameTF() {
    return usernameTF;
}

Calling custom COM-based library from Acrobat/Reader javaScript

Hi All,
is ist possible to extend the javascript object model? For example, is it possible to call a custom COM-based library from Acrobat/Reader using javaScript. Or is their a diffrent way to call third part libs?
Thanks

I need a Reader Integration to a document management system (DMS). The user should interact from Reader GUI with the DMS.
Nobody is able to give me binding statement, if my customer (this company need plugin for internal use only) will get the Adobe Reader Integration Key License/digital certificate for such a Reader plugin and how high the costs will be. I wait and wait for Adobes’ Feedback :-(
For this reason I check a different solution with Javascript but I have no idea how to make calls to the DMS from Javascript. On other side are COM- or .Net-based libraries available.

Is there any way to call methods of one view from another

Hi experts,
I am new to webdynpro.I am having some requirement in which I need to call methods of one view from some other view of same component .So is there any way to do this.

Dear Pradeep,
This will solve your problem......( plz 1st read everything ..)
There are 2 views :
i) Mandatory Attributes ' view(V1)
ii) Button' s View..(V2)
1. Create a method in Component Controller.( M1).
2. Goto V2 . In the Action Handler method of Button , call method M1 of component controller.
3. Write your Code in M1 instead of V2 method.
4. Create an EVENT ( E1 ) in component controller.
5. Fire this event from M1 before executing Action Code.
6. Now Add the event handler method of E1 in V1 ( i.e. Mandatory attributes view. ) ..........clear????? .. set "METHOD TYPE" = Event Handler. instead of Method.
7. In this event handler method in V1 , write the "check_mandatory_attribute_view" method.
8. use necessary flags..
Regards ,
Aditya.

Is it possible to call the SQL Server DB from jsp to java?

im doing a configurable system where you can create your own table using the system. i can do the creation of table by running the statement CREATE TABLE...........(with attributes) in java.
Let's say i have created tblST1 with attributes st_ID, st_Name, st_Description.
My problem is i dont know if it's possible to retrieve all the attributes from jsp to java.

jverd: i need your help. Iv read all the links u posted but im having a hard time in understanding them.
For the site http://java.sun.com/j2se/1.4.2/docs/api/java/sql/ResultSetMetaData.html , there's a code there which is...
ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM TABLE2");
ResultSetMetaData rsmd = rs.getMetaData();
int numberOfColumns = rsmd.getColumnCount();
boolean b = rsmd.isSearchable(1);
what i did was, i inserted it in my java code which is :
public boolean checkFieldTable2()
          boolean checked = false;
          try
               IRMS_DBConnect db = new IRMS_DBConnect();
               db.openCon();
               ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM TABLE2");
          ResultSetMetaData rsmd = rs.getMetaData();
          int numberOfColumns = rsmd.getColumnCount();
          boolean b = rsmd.isSearchable(1);
               db.closeCon();
               checked = true;
          catch (Exception ex)
               System.out.println("Error on Execution: " + ex);
          return checked;
and i compiled it and there was an error that the variable stmt was not initialized. Am i doing the right way?
Can anyone help me pls? pls pls pls

Create a batch file that will loop a copy command that will call it as a task from another application

I've created a script to copy large files from one system to another system. Unfortunately the transaction language of that system isn't feature rich, so I can't code a loop to copy multiple files to move concurrently. My goal is to create a batch file that
will do the loop of copying multiple files, after being called by the application that is copying the large files one at a time. Can I get some pointer on how to do this? Basically, the code is like this:
Copy from \\Server_1\directory\sent_file.xyz
To \\Server_2\Directory\received_file.abc
So the purpose is to perform the successful copy, then if the copy is good, execute the loop until completed.

Might look around here.

How to create context sensitive help and call the role based help from my Java Project?

Hello All,
I am new to Robo Help. I have created a Robo help for my Java Web Applicaion. My application is role base i.e some user's will not see some of the pages of the application. So I want to hide those pages in Robo help as well. I tried creating multiple TOC for different Roles.
My Question is
How to call robo Help from my application?(I will be calling using java script. If it is with RoboHelp_CSH.js where can I get that and How to implement it in my project)
How to implement role based help?
Thanks,
Siva.

I answered that. My point in asking whether it matters was that if it does, then you cannot use content categories and point different users to different categories and not allow them to see the others.
The alternative, as I said, would be to produce different outputs for each role.
As it does matter, then using webhelp you will have to use your RoboHelp project to produce a number of outputs, one for each category. Your app would install each webhelp into different folders and when your app determines the user role, you will link to the appropriate help.
There is another thread running where it has been explained by Willam van Weelden that you can achieve what you want using browser based AIR help. If that form of help can be considered, then the thread is at http://forums.adobe.com/message/4914753?tstart=0#4914753
Browser based AIR help must be run from a web server. It cannot be installed locally.

Call method with an argument from another view controller

I have a UIViewController MainViewController that brings up a modal view that is of the class AddPlayerViewController. When the user clicks 'Save' in the modal view I need to pass the Player data (which is a Player class) from the modal view to the MainViewController in addition to triggering a method in the MainViewController. What's the best way to accomplish this? I'm new to cocoa and have only tried using delegates and some ugly hacks to no avail.
Thanks for the help.

If I understand correctly, you have:
1. A model object, Player.
2. A top view controller, MainViewController.
3. Another view controller, AddPlayerViewController, which MainViewController displays modally.
I'm guessing that AddPlayerViewController creates a new Player object and lets the user set its values, and you need a way to get that new Player into MainViewController once they're done.
So, here's what I'd do:
1. Create an AddPlayerViewControllerDelegate protocol. It should declare two methods, "- (void)addPlayerViewController:(AddPlayerViewContrller*)controller didAddPlayer:(Player*)newPlayer" and "- (void)addPlayerViewControllerNotAddingPlayer:(AddPlayerViewController*)controll er".
2. Add an attribute of type "id <AddPlayerViewControllerDelegate>" called delegate to AddPlayerViewController. Also add a property with "@property (assign)" and "@synthesize".
3. Modify AddPlayerViewController so that if you click the "Save" button, addPlayerViewController:didAddPlayer: gets called, passing "self" and the new Player object as the two arguments. Also arrange for clicking the "Cancel" button to call addPlayerViewControllerNotAddingPlayer:.
4. Modify MainViewController to declare that it conforms to AddPlayerViewControllerDelegate. Implement those two methods (addPlayerViewControllerNotAddingPlayer: might be an empty method if you don't want to do anything).
5. When you create your AddPlayerViewController, set its delegate to your MainViewController.
If you need more detail, let me know what parts you need me to elaborate on.

Calling a backend bean method from another class

Hi,
I'm new in JSF & in this forum so maybe this question is already aswer.
My problem is that I made a jsf component to deal with a tree menu. The resources in the leaf nodes of the menu are stored in a action calling pattern (i.e.: #{myBean.myMethod}) & I'm looking for a way to bind & execute the call from the class of the component that treats the events.
I suppose that I need to get the current instance of the context, get the bean location, instance it & invoke the method, but I don�t know how.
I have another more question, may this resource invocation have any kind of undesirable side effect, I meen, it's me & not the faces context who is making the call so I'm not sure if that the best way to solve the problem.
Thanks in advance.

If I understand what you're saying correctly... you have a component which enables a user to select an action (leaf nodes in the menu). You are processing this selection in your component and now have a EL expression that looks like #{myBean.myMethod}. You now need to know how to use that expression from Java code to invoke it. Is that correct?
If so:
FacesContext ctx = FacesContext.getCurrentInstance();
MethodBinding mb = ctx.getApplication().createMethodBinding("#{myBean.myMethod}", new Class[] {});
mb.invoke(ctx, null);
This should do what you want. If you need to pass arguments to the method, you can do that as well... you need to pass in the types via the Class[], and the objects via an Object[] instead of null.
Note also that the API's for EL change for JSF 1.2 to the standard EL API's, however, the older API's (above) are still supported.

Calling results of a method from another class

Very very new to Java, so apologies for the lack of basic knowledge. I am making a programme with 3 classes. One class gathers details about a module. Another about the results of this module (which requires some of the information inputted for the first class). For some reason I cannot find how to use results created in the first class in this second class. How do you call the results of a method from one class in another class?
Thanks.

Thank you.
I am given the following information:
'_ModuleRecord_
This class is used to record information about a module taken by a single student. It has a constructor that takes three parameters:
a Module,
an int representing the examination mark achieved by a student, and
an int representing the coursework mark achieved by a student.
The class has another constructor that takes a single Module parameter.'
and the code looks like this:
public class ModuleRecord
public ModuleRecord(Module m, int eMark, int cMark)
public ModuleRecord(Module m)
} I am a bit confused by the whole thing to be honest. I assume that the Module is referring to the other class, but how do I forge the link between them here?
