How get BUS2089 into a Java WebDynpro

Hi,
I'm new to Java webdynpro programming. I have wrapped RFCs and used these but now I want to access attributes and methods on the SAP business object BUS2089.
Is it possible to import (auto wrap) a SAP business object into Netweaver dev studio then access the attributes and call the methods?? I can't find one...
Sorry if this is a 'dumb' question...
TIA
J

Hi,
You can access BAPIs and RFCs with webdynpro by creating a model based on RFC/BAPI. This will generate EJB's that you can use in your application to access the underlying business functionality on SAP. If you are doing this "outside" of webdynpro you can still access the business objects by using JCo (Java Connector).

How to include a Bapi or a TCD into my Java WebDynpro

Hello all,
Yesterday I finished my first Java WebDynpro Application ("Welcome"). That means, I am a beginner
But like I mentioned in the subject, I need Information about, how I can <b>include a Bapi or a TCD into my Java WebDynpro</b>.
This could be any information: verbal statements, Powerpoints, How-To-Guides, *.pdf's or something like that.
Thank you in advance and regards,
A. Cetin

Hello Ayşegül
You can find some information about webdynpro below link. But I dont understand exactly what do you want to do? You can call any BAPI easily inside webdynpro java.

How to organize into smaller java files?

I have a class which basically connects to a database and just about all of its methods query the database and return the results. The problem (which isn't actually a problem) is that the java file is getting so big because there are literally hundreds of methods representing different queries to the database.
Does anyone has any idea how to break this class into smaller files? Is there a "include" statement of some sort that I can use to include these "sub-java" files?

Does anyone has any idea how to break this class into smaller files? Is there a "include" statement of some sort that I can use to include these "sub-java" files?Different classes would still mean that user code would need to change.
The problem (which isn't actually a problem) is that the java file is getting so big because there are literally hundreds of methods representing different queries to the database.Depending on how that is organized that isn't necessarily a problem. For instance if it did nothing but manage calls and not extraction then it isn't a terrible problem.
If not then as previously suggested you break it by functional block. The closes model to what you have would be to break it into a class per each data model entity and then either add support classes for more complex support or add to one of the matching model entities.

MDM Hierarchy Table Into Tree (Java WebDynpro)

Hello all,
            I have a requirement of showing a MDM Hierarchy Table into Tree UI element.
These are the steps am following:
1) MDM Connectivity
2) Using RetrieveLimitedHierTreeCommand command to retrieve tree structure of the table
3) Using getChildren() method of each node to get the children
4) Made a tree ui element with a recursive node
Now since the Hierarchy table can reach any level of nodes how do i write code for dynamic tree node/leaf generation?
Please guide me through with detailed steps/code if possible?
Regards,
Yogesh Bhatia

Hi Yogesh,
After getting the HierNode you have to recursively populate the hierarchy tree using the below code:
private void createHierarchyTree( parent_element, com.sap.mdm.data.HierNode HierNode)
     if(HierNode != null && HierNode .getChildren() != null)
          for(int iChildCount=0 ; iChildCount < HierNode .getChildren().length ; iChildCount++)
               IPublic<comp name>.Iparent_element objTreeElement = parent_element.node<Recursive node name>().create<name>Element();
               objTreeElement.setattr1(HierNode.getChildren()[iChildCount].getDisplayValue());
               objTreeElement.setattr1_Recid(HierNode.getChildren()[iChildCount].getId().id);
               parent_element.node<Recursive node name>().addElement(objTreeElement);
// call the method recursively
createHierarchyTree(objTreeElement, HierNode.getChildren()[iChildCount]);
This will populate the tree, you need to create an action in the tree view and link it to TreeNode Type action property using which you can get the selected value.
Hope this helps!!

How get photo into iMovie

I have been trying to get a photo into iMovie from iPhoto or from my desktop. BUT It won't drop into my movie. What am I doing wrong?

Thanks much for responding. I have done all of those things, but the photo doesn't even show up in my choices once I click the camera. So it's something perhaps about how the photos are uploaded to iPhoto? They show up when I am in iPhoto, but they won't show up in iMovie when I navigate over to iPhoto. They are jpegs. I'm using iMovie / iPhoto from last year--that is, not the latest version.
Thanks for any more insight!

How do I get the proper UTF-8 NVARCHAR2 DB Value into a Java String?

Hello, I have a mixed char 8.1.7 database with UTF-8 as my NLS
charset. I used SQL Worksheet to enter test polish unicode
characters 50309,50310... into an NVARCHAR2 column using
insert...char(nnn using NCHAR_CS) and get the following result
from DUMP(columnname,1016):
Typ=1 Len=12 CharacterSet=UTF8:
c4,85,c4,86,c4,87,c4,88,c4,89,c4,8a.
Everything looks good.
Now, how do I get them out into a Java String and verify that I
have received the correct hex codes?
I have tried:
1. CHAR lChr = OracleResultSet.getCHAR(ColumnName, csUTF8); or
and lChr.characterStreamValue();
2. InputStream lIStr = arsResultSet.getBinaryStream(ColumnName);
3. String lStr = (String)arsResultSet.getObject(ColumnName);
and then:
lStr.getBytes("UTF-8"); or lStr.toCharArray();
I always get questions marks and negative byte values or the
values: 261,262,263,264,265,266.
I am using the latest 9.0.1. JDBC Thin drivers and the Oracle
extensions: OracleResultSet, OracleStatement etc...
Please let me know what class/method I need, to get the Oracle
NVARCHAR2 unicode string from the result set into a Java string
and what method to use to look at the underlying hex codes.
TIA for any pointers.

If I use in bdInt=sc.nextInt();a substring cannot be used.
Does anyone know how I solve this question without substring? Perhapse something I've mentioned above

How can I pass a value that is selected in a dropDownlist into a java metho

My explanation is below and heres my jsp and javascript code:
<form action="" method="post" enctype="multipart/form-data" name="form1">
<table width="90%" cellpadding="0" cellspacing="0" class="tblProperties">
<tr class="trBackColor"><td class="tdLayoutTwo"> </td></tr>
<tr class="trLayout">
<td class="tdLayout" align="right">Student Name: </td>
<td width="316">
<select name="studentID" id="studentID">
     <option value="0" selected>Select...</option>
     <%=frmStudent.createList(appStudent.getStudentID())%>
    </select>
</td>
</tr>
<input class="inputForm" type="submit" onClick="setValues(form1)" name="Submit" value="Continue">
</td>
</tr>
</table>
</form>Javascript code...
function setValues(frm) {
     var stuID = frm.studentID.value;
     <%=appForm.setStudentID(stuID)%>
     }I need to pass a selected value from the Form Dropdown into a java setMethod() in my jsp page. But I can't seem to figure out how? I used the "setValue" javascript funtion as shown above, that passes the value from Javascript to jsp on a onClick event, but it doesn't work. I did some research on the internet and have learnt that I cannot pass values from Javascript to jsp.
Is there any other method, may be after I hit the submit button? I need to pass the selected value from a student dropdown list to a jsp setMethod(). So for example if I select, Jon from a Dropdown list which has a ID = 5, then I need to pass 5 to the java method.
Any Clues?
Thanks

hi zub786,
you have to do following things:
1) Get the value of the selected index using javascript methods on selection of student ID.
2) Use hidden tag and pass that index to value of the hidden parameter.
3) Use that parameter in your next Jsp where you want that id.
I hope this info might help u.

How to pass a file into a java method

I am trying to pass a file into a java method so I can read the file from inside the method. How can I do this? I am confident passing int, char, arrays etc into methods as I know how to identify them in a methods signature but I have no idea how to decalre a file in a mthods signature. Any ideas please ?
Thanks

Hi,
Just go thru the URL,
http://www6.software.ibm.com/devtools/news1001/art24.htm#toc2
I hope you will get a fair understanding of 'what is pass by reference/value'.
You can pass Object reference as an argument.
What Pablo Lucien had written is right. But the ideal situation is if you are not modifying the
file in the calling method, then you can pass the String (file name) as an argument to the called method.

How can I read cookies in WebDynPro for Java

Hi,
in WebDynPro for Java I found a possibility to to get a "request-object" like the standard "HttpServletRequest-object"
IWDProtocolAdapter protocolAdapter = WDProtocolAdapter.getProtocolAdapter();
IWDRequest request = protocolAdapter.getRequestObject();
debugEnabled = (request.getParameter("Debug") != null);
With this request-object I can read request-prameters but I couldn't find a possibility to get cookies from the request.
There is no method like the "getCookies().method" in the HTTPServletRequest-Interface:-((
Has anybody an idea, how I can read cookies in WebDynPro for Java ?
Regards
Steffen

Hi,
This is the latest update I could look for regarding cookies and webdynpro.
Panic - WebContextAdapter is depracted - no more cookies now?

Help! How to read a .txt file into a Java class and make 2D array?

Hi guys,
Im a newbie with arrays, just started really using them.. please bear with me if I don't seem to understand much..
I have a .txt file that contains either a square or rectangle (random width and length).. How can I read each line into a Java class into a 2D array with rows and columns?

Example :
import javax.swing.*;
import java.util.ArrayList;
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.File;
public class ReadInto2DArrayExample {
    public static void main(String[] args) {

            if (fileChooser.showOpenDialog(null) == JFileChooser.APPROVE_OPTION)
                File file = fileChooser.getSelectedFile();
                BufferedReader reader = new BufferedReader(new FileReader(file));

                //Creating a 2D char array base on the array size
                twoDimesionArray = new char [array.size()][];
                //Convert array from ArrayList to 2D array
                for (int i = 0; i < array.size(); i++)
                    twoDimesionArray[i] = (char [])array.get(i);
                //Test the 2D Array
                for (int y = 0; y < twoDimesionArray.length; y++)
                    char [] temp = twoDimesionArray[y];

How do you convert a jar file into a java file, ?

how do you convert a jar file into a java file ?
I am new to Java ,but have a little experience in C++ and Visual Basic.
I want to edit and maybe create my own mobile games that are written or converted into jar files.
At the moment I am using Java NetBeans , and Easy Java( the java pad).
However the only solution I tried was to open the JAR file in winrar and see that its made up of png picture files,
midi music files and class files. Unfortunately when I uncompressed the JAR file , there was NO java file to be seen and the JAVA editors Do not show the class file like a Java file. So why is there no extension Java file in the mobile JAR game ?

Are you saying you want to take existing games and modify them? If the creators allow you to modify their source, then they'll provide you with that source (the .java files). If you're allowed to add things but not modify, you don't need .java files. Just documentation, which, again, the creators should be providing.
Or are you saying you want to create your own games and distribute them in jar files? If so, there's no need to turn jars into .java.

Inluding java webdynpro apps into portal transport packages

Hi All,
Platform: EP7 SPS13, solaris, oracle DB
I would like to know how to include java webdynpro apps into portal transport packages.
I was reading documentation but I was not able to accomplish this.
I have modified Pcd.TransportApplication.Export.ExcludeSystemObjects = false
in pcdStartup.properties file.
Transport export includes all my java webdynpro iviews, and export property RESOLVE REFERENCES is set to true in order to setup dependences to be included.
After importing in QA portal, I can see my java webdynpro iviews, but no webdynpro application exists and iviews won't work.
Any idea will be appreciated.
Regards.

Hi Claudio Roca ,
You ca nmove web dynpro applications to different landscapes in two ways
1) In NWDS u need to set Message server Port and server port of Quality or production depending on ur requirement
In NWDS ..In Menu you can find
Windows->perferenece there u need to do settings
and u need to deploy ur webynpro application
2) you can deploy .ear file in Visual Admingoto Visual Admin there u can find deployment button click it and deploy ur .ear file
Please reward points if it is helpful
