Creating a web provider for java portlets

Hi all,
i'm using
- Oracle Database Server 8i (Rel3 - 8.1.7.1.1)
- Oracle 9i Application Server (Rel2 - 1.0.2.2.2)
- Oracle Portal 3.0.9.8.2
I'm trying to crate a web provider in order to use java portlets, but there's a problem with:
"An unexpected error occurred: ORA-29531: no method getPortletList in class oracle/webdb/provider/web/HttpProviderDispatcher"
Does anyone know why?
I've searched for the class mentioned above but I can't find it..
thanks for the reply,
Alessio ([email protected])

The problem is probably caused by prohttp.jar becoming invalid or corrupt inside the database. The file is found in <IAS_HOME>/portal/lib (or jlib). Use the following command to reload.
loadjava -resolve <portal user>/<portal pass> <file path>/prohttp.jar

hello all,
i am new to web dynpro for java.i have already done an application
"Creating a Web Dynpro Application Accessing ABAP Functions" this application
have good document on sdn.
this application is working fine .
Now i got an requiremnt for creating a purchase order in web dynpro for java.
in normal report when i call the bapi the parameter are the header, headerx,item, itemx is an internal table.
CALL FUNCTION 'BAPI_PO_CREATE1'
EXPORTING
    POHEADER                     = HEADER
    POHEADERX                    = HEADERX
POADDRVENDOR                 =
TESTRUN                      =
IMPORTING
EXPPURCHASEORDER             =
EXPHEADER                    =

   RETURN                       = RETURN
   POITEM                       = ITEM
   POITEMX                      = ITEMX.
i just want to know how can i fill these internal table in web dynpro
for java to create an application accessing "Bapi_po_create" .
Thanks

Hi Gopal,
I'm not sure what is your issue, it seems you're not really understanding how the Model structure works in WDP.
I'll assume few things here, like you know how to Import the Model into the WDP, and you know a little bit about what Java Classes will represent this Model in the Project.
Try these steps:
1. Import your Model into the Project;
2. Open your Component Modeler, create a Data Link between your Model / Component (Or Custom Controller, as you prefer)
- You can also use the "Apply Template -> Service Controler"
3. Map the Input of your Model as the Main Node, check the Input Tables (you prob. will have two, POITEM = ITEM - POITEMX = ITEMX)
4. Also, check the Return box, since this is BAPI return (You can use to display Backend messages)
Now you have the Model mapped into your Controller, you need to develop the Java function to execute it.
1. Create a new Input class, like
BAPI_PO_CREATE1_Input purchaseOrderCreateInput = new BAPI_PO_CREATE1_Input();
2. Bind your Input Node, in the Controller, with your Input Class;
wdContext.nodeBAPI_PO_CREATE1().bind(purchaseOrderCreateInput);
3. Set any Import parameters you need:
purchaseOrderCreateInput.setEXPPURCHASEORDER(XXXX);
4. To Add references to the Table, you will perform something like:
First, you need to know what "Structure" you need to add (POItem Structure) - You have a Java class that represents that Structure..
POITEM_Element poItemElement = new POITEM_Element();
poItemElement.setPROPERTY();   /// Set your Properties
purchaseOrderCreateInput.getPOITEM().add(poItemElement);
5. Execute your Input,
purchaseOrderCreateInput .execute();
Hope it helps,
Regards,
Daniel

Creating Sales Order using Web Dynpro for java

Hi SDN,
I am new to Web Dynpro for java. I have developed an application for creating a sales order using adaptive RFC Model using BAPI. It's working fine when i create a single order. I wanna create SO with more than one line item. I have used the Table UI Element to do so. But i could not able to enter the 2nd item details. Please suggest me how to pass more than one line item from the Table UI element.
Thanks in advance.
Regards,
Basha

Hi Basha,
Do you need to display the header items and detailed items?
If the BAPI Contains Output values in R/3 side.
I mean to say if BAPI contains 4 line items.u can get thru wdjava the followinf way.
1. Create webdynpro application.
2.Import the model.
3.Create Customcontroller and model binding .
4. Write the execute method in controller.
BAPI b = new BAPI();
WdContext.node<BAPI>.bind(b);
give inputs for BAPI
b.setname(" ");
b.setno("");
wdContext.currentBAPI().modelObejet().execute();
wdContext.node<output>.invalidate(); in try catch
5. create view or when u give the dynpro application its
in the add custom to view and drag BAPI custom to view .
6.Crete UI for ur table thru insertTemplate table directly mapp the output values.
7. deploy and run
U can get the out line items .
Or any thing else post ur requirement.
Thanks

Can I Design a Forum with using web dynpro for java?

Hi All:
Can i design a forum with using web dynpro for java?
I want to design an application like a simple forum which maybe has many replies.So if i use
the UI technology "web dynpro for java", i will to create UI elements dynamically.How can i control this
dynamical UI elements to keep layout ?

Hi,
yes you can do that....
for exaple if you observe SDN...
you can imagine like....
A big Transparent Container(TC)....
Inside that number of other TCs(depending upon the question nd its replies...)....
In side each TC, again around 9 UIElements....
one for menioning what is the question/reply?
other for your description of question/reply...
other for your name,
displaing your fourm point... etc...
So it will be
for(loop till your (Question+No of replies))
Create Transparent Container....
Add Childs to the Container...
Decide your layout....
In case if you want to know how to create UIElements dynamically....

Notification Service in Web Dynpro for Java?

Hello Experts,
I'm new on the topic "web dynpro for java" and have a question about a real-time-notification of web dynpro clients.
In web dynpro for abap ther is apparently a new solution called "Notification Service" (since NW 7.0 Ehp2).
Details: http://www.sdn.sap.com/irj/scn/elearn?rid=/library/uuid/f0802995-3433-2c10-2787-d7db51352891&overridelayout=true
But I found no hints how to solve the problem of a real-time notification in web dynpro for java.
Requirements for short: The server can trigger a refresh in one or more web dynpro clients.
Requirements a liitle more extended:
1. A web dynpro is running in a browser and shows data it gets from a DataBase table1
2. Now a function module1 is started by an event and changes the data in table1 on the server side, the web dynpro does not know about this event or the changes made by external components.
3. These changed data should be visible immediately in the running web dynpro after the event occurd --> trigger a refresh of the web dynpro from the function module1?
All I actually know is that: The web dynpro can update its context with the new data from table1 after a refresh of the gui (wddomodifiyview). Using a timed trigger I can get new data after x seconds (same way --> context update and gui refresh). Is there another way to refresh the web dynpro (that noticed requirements of #3) ?
Regards,
Anja Hormann

I recommend that you create another Web Dynpro application with this Timer to execute an RFC. This application would be in a Web Dynpro iView hidden from your SAP EP and shoot an event that would be captured by another application.
However I would take great care with this type of application.
And to answer your question at the moment, to my knowledge, there is no solution for this kind of integration between the ABAP and JAVA.

Angelo

Reg:Locking in Web Dynpro for JAVA.

Hi All,
When a user logged in the front end i am calling the lock function module(based on this locking mechanism is working) and when a user logged out i am calling the unlock function module(now the locked mechanism is getting unlocked).
now my problem is when a user closes the window abruptly without loging out,the unloeck mechanism should work at that particular instance.Please suggest me if this is possible or not in web dynpro for java.
Thanks,
Mahesh Nuli.

Hi,
I will give you two different solutions, use whatever you think fits best for you.
First One:
Whenever you call your "LOCK" function module, do not disconnect the ModelInstance. Create a Locking method in Java which returns a "com.sap.tc.webdynpro.modelimpl.dynamicrfc.DynamicRFCModelClassExecutable" instance. It should look like this:
InputClass inputInstance..
node.bind(inputInstance);
inputInstance.execute();
if fails, return null;
otherwise, return your inputInstance;
Keep this inputInstance into some Context Attribute. Whenever you wanna "Unlock", you can disconnect this input from the backend system.
InputClass inputInstance = wdContext.getInputInstance();
inputInstance.modelInstance().disconnectIfAlive();
This will work for all the cases you are currently having problem. However, this solution holds one connection.
Second One:
Assuming your transaction runs in one View, you can set this View lifecyle to "when_visible" - Doing that, whenever you navigate "away" from this View the method wdDoExit of that ViewController will be executed.
In this appoach, you dont need to store any "InputClass" - You can perform your Lock and disconnect from the backend. In your wdDoExit method you can code a "Disconnect If Connected" method.
Use whatever fits best.

Daniel

Design header in Web Dynpro for java

Dear experts
I used PageHeader UI Element for design header in web dynpro for java. How to insert a image and set padding logo in page header?
Ex : Create a SAP header includes the content as SAP logo, application title, functions, user name, logout button.
Thanks.

Hi,
I couldn't understand your requirement for keeping an image in page header but i suggest you not to do so, because it is not a good practice and creates a performance issue. Page header UI element is not much customizable for same purpose and should not contain interactive UI elements according to [UI Element Guide|http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/b06c8c9a-19a4-2b10-d985-9ae7a4383478]. You can also refer to the same document for the usage of the Page header and other UI Elements its a very useful and nice article.

Overlapping labels in Scatter Graph - Web Dynpro for Java

Hi
We have created a Scatter Graph in Web Dynpro for Java.
The xValue and yValue are obtained from a node. We are showing a name as the label on each point so plotted on the graph through Chart Designer (Format->$Label).
The issue we are facing is:
We have 3 points with the same xValue and yValue. Meaning they plot the same point on the graph. But the name associated with each is different. These names are overlapping (as its the same point on the graph) and are hence not readable.
Is there any way in which we can show multiple names/labels on the same point in a readable way?
Is it possible for us to show a tool tip at each point where the tool tip contains the comma seperated names/labels associated with all the x and yValues at that point?

Hi,
there's no automatic mechanism for detecting such label collisions in the scatter chart. However, you can change the position of each label (HorizontalPosition, VerticalPosition) and use point customizing to position several labels around this single point.

Using Apache Commons HTTPClient to create a custom socket for Java mail

Does anyone know how to use Apache Commons HTTPClient to create a custom socket for Java mail. This is necessary for me to use NTLM authentication

JavaMail doesn't use HTTP.
If you want to add support for NTLM authentication to one of the standard protocols,
your best bet is to create a SASL provider, although note that only JavaMail's IMAP
provider uses SASL currently. The other protocols should add SASL support, but that
hasn't been done yet.

Catch event from Web Dynpro for Java

Dear guru's,
we have a working Web Dynpro for Java. It delivers a company code that needs to be routed to a visual composer model. In the Web Dynpro we use the WDPortalEventing.fire command to trigger an event named 'ShowCompanyCode' in namespace com.sap.vc:epcm. In the visual composer, I used a 'signal in' for the same namespace and event name. However, the supplied value for the company code is not received. Both iviews (from VC and Web Dynpro) are on one page.
I have enabled the flash debug console and did some testing with a VC model that consists of two iviews on one page. Here it does work. I have found some differences in the debug output that points in a direction.
In the case of the VC iviews, I get the following string in the debug console: signalinAHAPP -<Params version="2" ><Row STR1="1000" /></Params>. This results in a correct transfer of company code value '1000'.
When getting the info from the Web Dynpro iview, I get the following string: signalinAHAO8 -1000. It seems that the web dynpro does not supply the values in a correct way. However, the same mechanism is used to supply the data to another web dynpro iview and that works fine.
Do we have to use special coding to be able to fire the event to a VC iview? Any help will be appreciated and points will be awarded!
Thanks,
Arno

A. Van de Camp,
You can create two iViews that communicate with each other on the same page, using client-side eventing, so that the output of the first iView serves as the input to the second. Eventing in the portal is based on the use of the Enterprise Portal Client Manager (EPCM), an object defined by the portal client framework to handle functions such as client eventing.
To define eventing between an iView created and existing in the portal(web dynpro iview), and an iView created in Visual Composer:
1.Check the properties of the existing portal iView and find out its EPCM event name.
2. In Storyboard, open the iView that is to be the second part of the eventing scenario and create the required port: as input or as output.
3. Double-click the newly-created port and in the Configure Element task panel, enter the portal event name in the Signal name field and the EPCM event in the EPCM event field.

Sami

Parse errors while creating a Web service from Java class!

Can anybody tell me please, is it possible to create a Web Service from java class where the input from user is required ?
I have the following program, which is successfully compiled, but when I'm trying to make a web service in JDeveloper, the following error occurs:
"Validation failed.
The implementation class primePackage.isPrime ofport type MyWebService contains parse errors."
import java.io.*;
import java.util.*;
class isPrime
public static void main (String args[])
Scanner reader = new Scanner(System.in);
int n;
System.out.println ("Enter a number you want to know is it prime or not");
n=reader.nextInt();
if (isPrime(n))
System.out.println ("True");
else
System.out.println ("False");
static boolean isPrime (int n)
int i=2;
while (i<=n-1)
if (n%i==0)
return false;
i++;
return true;
}

Hi,
Can anybody tell me please, is it possible to create
a Web Service from java class where the input from
user is required ?Yes, the parameters of your method will be mapped in WSDL.
But i've some considerations about your code.
I suggest you change the name of isPrime do Prime, its a good code convention to put the name of class starting with Upper case. and isn't good the name of class equals to name of method.
I suggest you to change the "static boolean isPrime (int n)" to "public boolean isPrime(int n)" to publish a method as a WebService method it's must be public and not static. After this change try to generate your Web Service.
Regards.

How to create a Batch file for java application ?

HI,
How to create a Batch file for java application ?
And whats the use of creating batch file ?
Thanks in advance

[http://static.springsource.org/spring-batch/]
Assuming you want to develop a batch application rather than actually just create a .bat file ..

HOw to create a Batch file for java application and whats the use of this ?

HI,
How to create a Batch file for java application ?
And whats the use of creating batch file ?
Thanks in advance

First of all, you're OT.
Second, you can find this everywhere in the net.
If you got a manifest declaring main class (an classpath if needed), just create a file named whatever.bat, within same directory of jar file, containing:
javaw -jar ./WhateverTheNameOfYourJarIs.jar %*By the way, assuming a Windows OS, you can just double click the jar file (no batch is needed).
Otherwise use:
javaw -cp listOfJarsAndDirectoriesSeparedBySemiColon country/company/application/package/className %*Where 'country/company/application/package/' just stands for a package path using '/' as separator instead of '.'
Don't specify the .class extension.
Javaw only works on Windows (you asked for batch, I assumed .BAT, no .sh), in Linux please use java.exe (path may be needed, Windows doesn't need it 'cause java's executables are copied to system32 folder in order to be always available, see PATH environment variable if you don't know what I'm talking about) and use ':' as classpath (cp) separator.
The '%***' tail is there in order to pass all parameters, it only works on Windows, refer to your shell docs for other OSs (something like $* may work).
This way you have a command you can call to launch your code (instead of opening NetBeans just to see your app working). You could schedule tasks on it or just call it in any command prompt (hope you know what it is 'cause there have been people in this very same forum with no clue about it, if not just hold the 'Windows button' and press 'R', then type 'cmd' and run it).
Finally add dukes and give 'hem away.
Bye.
