Table Entry Insert - Java Programming Question

I design table input/output interface with adding / deleting entry function. Table data will be saved in AbstractList by BAPI.
In Controller implementation tab, I created "input" under WD_init()
 Bapi_Entrysheet_Create_Input input = new Bapi_Entrysheet_Create_Input();
 wdContext.nodeBapi_Entrysheet_Create_Input().bind(input);
 input.setEntrysheetheader(new Bapiessrc());
In view action function, I need "input" as.
input.addEntrysheetservices(new Bapiesllc());
My question is how I can let view class know "input".
Thanks.

Hi li dong,
You need to establish context mapping between view and controller. Open view, select "Properties" tab, In "Required Controllers" section press "Add" and add your controller. Create model node in view (Bapi_Entrysheet_Create_Input) and click "Edit context mapping" in context menu for node. Establish context mapping. Than you can call
wdContext.nodeBapi_Entrysheet_Create_Input().modeObject().addEntrysheetservices(new Bapiesllc());
from view.
Best regards, Maksim Rashchynski.

How to display a oracle table from a java program?

How to display a oracle table from a java program.
Hello friends, I have written a Java program, using oracle 10g as backend.
I want to display a oracle table as output. Im not getting how to display oracle table as a output table.. Pls help me
Thank you

jayanthds, you're not going to get a satisfactory
answer to this here. it's too big a task to justbe
quickly outlined in a forum - the reply "all youneed
to do is to query you table and return it asJTable"
is worthless, for example, since the solution to
any problem can be distilled to such a
soundbite, if need be. doesn't make the solutionany
simpler
essentially you're asking "how do I write adatabase
application?". all you'll get is snippets of code
that, when fitted together, will eventually helpyou
do this, but you'll spend days and days comingback
saying "right, I've done that, now what?" until
either you or the forum gets frustrated with the
whole affair and the process stops
there are entire books written about this subject,
and countless tutorials and guides on theinternet.
you're better off going down that routehehehe.well, it's true! I used to have a manager that would outline the solution to a problem in a few lines of pseudocode, and then firmly believe that the actual solution would be just as brief and simple. shame his pseudocode included such lofty abstractions as "reformat all data"

Java Programming Question

Hi,Everybody:
I have a question about Java programming. If I want to write a java class code called if.java like below, how should I do to make it pass the java compiler and make it work. I know the words "if" and "for" are reserved words. I just try to figure it out that is it possible??? Do I need to create my own java compiler or recompiler?
public class if
public if() { }
public static for test()
return new for();
public class for
public for() { System.out.println("for class constructor"); }
}

I don't think you can bypass the compiler's rejection of this. There is little point to naming the classes after keywords. Not sure if it's case sensitive though, so maybe "If" or "For"? Otherwise, try "if_" or "for_"

Inserting JAVA program in HTML

I want insert a program made with JAVA in a HTML file. How can I do it? I think is not possible!!
THANKS, JUAN

I have a hard time believing that this can't be an applet. You might not want it to be an applet, but you should be able to do anything in an applet that you can do in an application. The only way I know to run it on a web page is to make an applet.
If this has to be an application, I think you're only option is to allow the user to download and run it.
Here is a link for making jar files more or less runnable.

Accessing oracle DB from a java program - question for oracle driver

Hi,
I have Oracle 10 G under vista on my desktop. I am trying to write a simple java program to access/update database tables. I saw in one of oracle example to import 2 packages - namely --- import oracle.jdbc.driver.*; import oracle.sql.*;
Where do I find these 2 packages. Also I read some documentation to download drivers. I would like to use 2 drivers, the thin driver and the OCI driver. Can someone tell me where I can find these drivers and where do I copy these two drivers - so javac and java command can recognize it.
I will greatly appreciate the help. Julia

You can download the drivers from http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/index.html.
Note that oracle.jdbc.driver is desupported after 10.2, http://forums.oracle.com/forums/ann.jspa?annID=201, so you might want to consider using a DataSource to provide Connections.

Java Programming Questions

I have taken a couple class in Java programming in just regular programming with GUI/console. I am looking to further my programming skills and wonder what course I need to take to become a java programmer for companies. I am confused on all this language in Java and there does not seem to be any reference to explain exactly what these technologies are. Example is.....What is J2EE? What is .JSP? Are they the same things? What environment is most commonly used in jobs? What about Java certifications?

Here's the path tree to become a Java Programmer from Sun Microsystems:
http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getlppage?page_id=212&path=SJPF
There are other paths like Web Development and Databasing, so click around if you're interested in those. I think for a standard Java Programming job you will want the "Java Programming for Professionals - Sun Certified Java Programmer".
However, most Jobs are specialized and require skills like JSP Development or Java Enterprise. Look around at a job search site and see what types of skills Java jobs are asking for.
I've noticed, for example, that Java web jobs generally require: PHP, HTML, JSP, XML, SQL, etc.

i have trouble knowing when something is referred to
in contrast to something being copied.Java has only one passing mode: pass-by-value. The value, whether it be of an int or a reference, is always copied.
in this case, the array has changed, but not the
character.A reference has a value, that value is either null or the address of an Object. The value of scores is the address of the array returned by getArray(). When you pass scores to mystery() the value of scores is copied to a new reference called b on the local stack frame. The value of b is the same as the value of scores, but they are two different references. However, since the value is the same they both contain the same address which is the address of the array. When you modify the array you are modifying the array at the address that b has as it's value. Since scores has that same address as it's value, in other words they both point to the same array, you will see it modified in both places. When you passed the char the value (L) was copied to the local stack frame. Your copy r now has the value L. Modifying r modifies the value at r, which is independent of the value at x.
So, with the char you changed the value at the address. With the reference you changed the value at the address the reference contained as it's value.
and in this case, why didn't the array change?You didn't modify the array, you simply printed it's contents concatenated with an empty String.

Accessing DB2 data through DBLINK in Java program recieves ORA-02063 error

Hello,
Is it posible to access a mainframe DB2 table through a Java JDBC connection utilizing a DBLink / Synonym. Using Toad or SQLDeveloper, I can select the DB2 data just fine. Also, PL/SQL programs can access the data without issues. When I try to select data from the DB2 Table in a Java program, I get ORA-01002: fetch out of sequence -- ORA-02063 preceding line from DB2D errors.
The code I am using to test is:
(Note: TBL_LOC_ADR is the Synonym that points to the Mainfram DB2 table)
public static void main(String[] args) {
          Connection con = null;
          Statement stmt = null;
          String query = "SELECT * FROM tbl_loc_adr";
          ResultSet rs;
          try {
               System.out.println("Getting connection");
               con = BatchDBConnection.getDBConnection();
               TestConnection tc = new TestConnection();
               System.out.println("Creating ps");
               stmt = con.createStatement();
               System.out.println("Calling qds");
               rs = stmt.executeQuery(query);
               System.out.println(" Returned data " );
          } catch (Exception e) {
               System.out.println("Error " + e.getMessage());
               e.printStackTrace();
The error occurs on the rs = stmt.executeQuery(query); line.
Thanks for any input into this error. It's been driving me nuts all day.

Using the Insert statement in a Java program without hardcoding the data

hello.
this is james mcfadden. i have developed a program called Demo.java, which is used with another program called QueryTableModel.java (a program that allows data to be viewed in a JTable). The Demo.java program displays a menu, connects to a database, allows the user to add data into the database and allows the user to view data that is already in the database. I have a problem with the Demo.java program. I have hardcoded the Insert statement in it. How do you use the Insert statement to put data into a database without hardcoding the data?

How to trigger a java program on INSERT in SAP HANA

Hi,
I need to trigger a java program whenever an INSERT happens on a table in SAP HANA.
Please tell me how can I achieve the same.
Thanks & Regards
Divyank Mehta

Hi Mehta,
HANA SQL Script is not able to call external commands . May be from the context of your Java , you can keep pinging the database where the insert is happening for a data change via JDBC or ODBC . From SQL Context I don't think it is possible.

How to insert a button on the column header of a table in webdynpro java

Hi
Can anyone tell me how to insert a button on the column header of a table in webdynpro java?
regards
sunit

Hi sunit,
Instead of adding button in the column header , in the column
add a fixed top cell.
    right click on the column
    Insert FixedTopCell
    Right click on the fixedTopCell
    insert Editor.
   select button.
then button will be only in the top most row.
Hope it will satisfy ur requirement
Regards
