Passing Value from PDK Java to Webdynpro Java in SAP EP SP18

Dear Experts
Please tell me how to call a webdynpro java ivew form a PDK java application and I need to pass a value to webdynpro form my PDK application.

Please help me in this issue

Noel,
From your PDK aplication you will be providing the WD URL along with the parameter.
Say in your PDK application you redirect to http://portalserver:50000/irj/local/webdynpro/sap.com/test?mypram=1
In WD you fetch this parameter using WDProtocolAdapter class.
Check below links for more information.

Hi Rakesh ,
We can pass value the concept of following comes into picture :-
· dataObject
This parameter contains the transported parameter of the portal event.
· Namespace
This parameter contains the name space of the received portal event.
· Name
This parameter contains the name of the received portal event.
Refer to this for more details :-

If you choose the second alternative you should erase these global variables after the second form is opened
You can erase the global variable using:
erase('global_var')

Hi Praveen,
The concept what we have observed is When you click on Submit the values were sent to GP. There GP framework takes care of all these. After that when you try to login to Portal and click on GP Inbox and try to open the application, what ever the data that is sent previously will be retrieved.
Due to some reasons like Delegation and other conecpts where GP will not fit we have scrapped GP and got back to workflow. There we have used the concept of Portal Webservice inorder to send the data to R/3 by clicking on Submit button.
We have successfully implemented the Adobe Forms Offline Scenario using Portal Webservice.

How to pass value from Javascript function to a Java class method

Hi All,
I want to pass a value, which I catch in a Javascript function to a method in a Java class. I have tried many combinations but it gives me error.
This is the way I am doing
function assignBill() {
proj = projPh.substring(0,indSlash);
<% myproject.getProj(" project_cd = '" + proj + "'");%>
proj is the variable which I want to pass to getProj methods.
If any one has done this, please let me know. Thanks for your help.
Ritesh Mehta

The only way to receive something from clients page is to submit it somehow: through a form or link, but the info has to make it back to the server obviously. I dont know how your app works, but you can use the the javascript -location.href- function(i think) to submit the var to the server and process it there.

Pass value from Java to Perl

Anyone knows how to pass value from Java to Perl program?

Did you write the perl program? Can you change it? Or are you trying to interface to something that already exists? This will limit your options, of course.
Anyway the first option is simple. The java program does this:
System.out.println("This is a line of input.");The perl program does this:
while(<>)and in that block, $_ is assigned to each line of input.
Then you can invoke both like this:
$ java MyJavaProgram | perl MyPerlProgram.pl

Java Thread - difficulty while passing value from parent to child thread

Hi All,
I am calling a java program from a unix script .
My oblectives are
1)to pass value from scripts to main java class
2)main class should create a child thread and pass data to child and should return control back to script
3)child thread should run independtly of parent
The calling unix script is part of process and hence should return control back to its calling script immediately.
Findings
1)Without passing data thru setter getter /constructor method to child thread my objectives are met
2)When I pass the data from parent thread to child thread calling unix scripts wait till child thread finishesh its working
call.scr
java Main <list of Arguments>
Main.java
public class Main
             public static void main(String args[]) throws Exception
             String data2="Z";
             String data1=null;
             for(int i=0;i<args.length;i++)
                  data2=data2+","+args;
data1=data2;
Child cu=new Child();
cu.setData(data1);
data2=null;
data1=null;
cu.start();
Child.javaclass Child extends Thread
public String data;
void setData(String data)
this.data=data;
public void run()
----------> processing on data
I think due to passing of data from parent thread to child thread (Inter thread data communication/Inter process communication)
the threads are not working as desired.
Plz anybody can suggest something.....
Thanx.

aschin,
You seem to be confusing Java Threads with Operating System Processes.
If you want you're java program to run in the unix background then you'll need to run it in the unix background. Java (being o/s agnostistic) doesn't provide process manipulation functionality (which would include the ability to throw itself into the background, as a C program can) in the standard API, and it's hard to imagine any third party producing anything as low level as a process controler... so yeah, just start the java program in the background... and you'll need to workout some interprocess communication protocol... named pipes have worked well for me in the past, as they doesn't suffer from the quit same performance issues as real disk files.
Good luck. Keith.

Access webdynpro value from PDK

Hi ,
Can i know how to access a value set in webdynpro from PDK java?
Example
from webdynpro--
WDScopeUtil.put(WDScopeType.CLIENTSESSION_SCOPE, "BP_ID", "value");
i would like to access the BP_ID value from PDK java. Can i know what is the method ?
Thanks in advance.
Sujith

Just to keep you guys informed... found its not possible to solve the above issue because of underlying architecture differences.
Hence to track a session / user, better use cookies which is possible both in pdk and webdynpro.

Passing data from Oracle stored procedures to Java

We're going to write a new web interface for a big system based on Oracle database. All business rules are already coded in PL/SQL stored procedures and we'd like to reuse as much code as possible. We'll write some new stored procedures that will combine the existing business rules and return the final result dataset.
We want to do this on the database level to avoid java-db round trips. The interface layer will be written in Java (we'd like to use GWT), so we need a way of passing data from Oracle stored procedures to Java service side. The data can be e.g. a set of properties of a specific item or a list of items fulfilling certain criteria. Would anyone recommend a preferable way of doing this?
We're considering one of the 2 following scenarios:
passing objects and lists of objects (DB object types defined on the schema level)
passing a sys_refcursor
We verified that both approaches are "doable", the question is more about design decision, best practice, possible maintenance problems, flexibility, etc.
I'd appreciate any hints.

I'd appreciate any hints.If logic is already written in DB, and the only concern is of passing the result to java service side, and also from point of maintenance problem and flexibility i would suggest to use the sys_refcursor.
The reason if Down the line any thing changes then you only need to change the arguments of sys_refcursor in DB and as well as java side, and it is much easier and less efforts compare to using and changes required for Types and Objects on DB and java side.
The design and best practise keeps changing based on our requirement and exisiting design. But by looking at your current senario and design, i personally suggest to go with sys_refcursor.

Passing value from Webdynpro ABAP to Adobe form..

Hi experts,
In first view of web dynpro, im getting employee id as input and after clicking the create new button, an adobe form is called
to create the employee details ( in form i used the submit button and i stored the details ). so, in tat form i used the employee id as read only mode and it has to display the value which i given as input. But in tat form im not getting the value from web dynpro..
can anyone plz help me out for this..
Thanks in advance..

Hi,
Try to set your values in Method->"wddomodify" of the View in which Adobe Form is present. If you want to pass values from one view to another then check this link [Passing Local Parameters between views in an ABAP Web Dynpro Application|http://wiki.sdn.sap.com/wiki/display/stage/PassingLocalParametersbetweenviewsinanABAPWebDynproApplication] or use Context declared in Component Controller.

Sridhar

in a servlet :
parse your xml file (see how at the end of the post) and
put the values you want in the request attributes
request.setAttribute("value1", value1);
...redirect to the jsp
in the JSP:
get the wanted attributes:
String value1=(String)request.getAttribute("value1");To learn how to parse a xml file, pay a look at this page, it explains how to read the XML document to build an object representation, and then how to navigate through this object to get the data

Hi Pradeep
Steps:
1. First create an instance for bapi and bind the instance to the bapi node.
Z<bapi name> zb=new Z<bapi name>();
wdContext.nodeZ<bapi name>. bind(zb);
2. Then if u have the import parameter u have to set them by using
    The instance of the above bapi.
    Zb.set<import parameters>;
3. If the bapi has a table parameters then the structure for the table parameters will also be imported
   In the model class.
4. Set the table parameters by creating the instance for that structure and using this instance set it.
   Z<Struct>itm tab=new Z<Struct>();
   Tab.set<table parameters>
5. Then add the structure instance to the bapi instance.
    Zb.add(Tab);
6. Then Execute the bapi after setting the import parameters.
7. If there is any export parameters, then get the values after execution.
Look at this thread for codes
