Vadnala,
Go to SE24 to create your class interface and take a look at the tutorials we have spread in the SAP help and SDN. Take a quick look at BSP aplications SBSPEXT_*.

How to find (classes,interface,subpackage info) in some package

Plz tell me if any one know how to find (classes,interface,subpackage) in some package
e.g. in java.io
"Above senerio in not concern with java doc
but tell me if an other way i.e by help of programming
i could find some package information"
as we know we find out any "object" classType , methods and fields information with help of "java.lang.reflect" API's
but how to find a package information as provided by jdk is in current use

You can locate the .zip or .jar file where the stuff is, and say either
unzip -l classes.zip
or
jar tvf classes.jar.
So you see the list of the classes in the given package.
Then you can say
javap -classpath classes.zip MyPackage.MyClass
to see the fields and methods of the given class.

How to create an interface if the class has a nested class

I have the following class
public class SampleImport{
public SampleResult import (InputSource xml) {
SampleResult sampleResult = new SampleResult();
          //do something
          return sampleResult;
public static class SampleResult {
          public final String sampleName;
          public SampleResult (String s) {
               sampleName = s;
I would like to create an interface for this class for teh following method signature 'SampleResult import(InputSource(xml))', how would I create it ?
Any help is appreciated,
TIA,

public interface Nameable {
    String getName();
public interface Importable {
    Nameable importSource (InputSource xml);
public class SampleImport implements Importable {
    @Override public SampleResult importSource (InputSource xml) {
        SampleResult sampleResult = new SampleResult("foo");
        //do something
        return sampleResult;
    public static class SampleResult implements Nameable {
        public final String sampleName;
        public SampleResult (String s) {
            sampleName = s;
        @Override public String getName() {
            return sampleName;
}edit: er, you do know import is a keyword?

How to create Tagging Interface?

Hello, Java expert around the world, pls help me on this:

How to create customize tagging interface?

We need it to mark a class!
If your class implements Serializable then you are saying it is ok to be serialized.
It's just a way to indicate that a class is capable of something, to tag it in some way.hmm...a class is capable of something....if a class implement java.io.Serializable, then what are the things that the new class capable to do?
Where is the functionlity(method, or behaviour)? Since there is no method declared under this interface...

Package
I have to create Web Application whose name should include _ like ztest_test
The system is not allowing me to create web application whose name includes _
Can you please how I can create web application whose name includes _
I am not allowed to use the wizard or manual method to create web interface.

[Solved]How to create ADF interface View

Hi All,
I have a design problem that I need some help with.
In one of the pages in our application, we have two drop down boxes one with account type and another with account name (label) and account number (value).
The account types are Escrow, Credit and Misc (some other types). all three types are in three different tables.
Now the problem is, in the page when the account type is selected, the second drop down box should be filled with respective account numbers.
So my question is Can I create an interface view and implement in all three different account type views and use it for second drop down box.
Thanks in advance for your help.
Thanks

You might do a VO with a union of the three tables - use a custom SELECT like this:
SELECT 'Escrow' account_type, account_number, balance, ... FROM escrow_accounts
UNION
SELECT 'Credit', account_number, balance, ... FROM credit_accounts
UNION
SELECT 'Misc.', account_number, balance, ... FROM misc_accountsUse NULL for any column in a table that does not have that column. I'm not sure if you can use Entity Objects (one EO per table) with such a VO to make the data updatable - it might have to be a read-only VO.
Or create a database view with this SELECT and base the VO on that view instead of a table. You can even make the view updatable with INSTEAD OF triggers and base an EO on the view.

How to create an interface

Sorry for the newbie question. I was provided a class, and they said that in order to use this class the interface can just construct a new SampleClass and method1() followed by method2(). I've looked over the documentation on interfaces, but I still don't get it. I was hoping someone could give me some guidance as to how to use method1() and method2() in my class.
The SampleClass starts off like this
public class SampleClass extends java.io.File {
public boolean method1 {
return true;
public void method2 {
sample.start();
} //my class
public class MyProgram {
public static void main(String args[]) {
}}Thanks in advance for the help!

Ok. Here's the actual program that was given to me. When I do AudioFile af = new AudioFile();. It says that it's unable to resolve. So when I asked the guy about this, he said that I need to use an interface.....again sorry for my confusion.

How to creat the interface of auto CAD file with labview

Hi
I have been controling 2-axis Piezo motor with labview. Now I have to use the dwg or dxf file to move the piezo controller axis. How I can transform the dwg or dxf file into decimal number 1, -1 to create interface with my labview.

Hi Nusrat,
So it sounds like you want to create a CAD drawing and then control your piezo motor via LabVIEW by moving the CAD drawing? Is that correct?
If that is correct - I don't know of a way to do this I'm afraid. I don't think it's really possible.
The only potential way to do this is to use SolidWorks as your CAD program and then convert the SolidWorks drawing into an STL file, which can then be imported into LabVIEW as a 3D picture control. I can't think of any other way to achieve this.
These examples might help you:
LabVIEW Interface VIs for SolidWorks
STL Geometry in 3D Picture Control
The Pitch Perfect Tuner
Develop Motion Applications with RIO and SolidWorks
NI SoftMotion for SolidWorks
Connect NI LabVIEW and DS SolidWorks
I hope that helps.

How to create an interface for extractors from CRM to BI/BW

Hi Experts,
My aim is to bring in data from CRM source to BI/BW target so for that we have found few extractors in CRM side which we need to use in BI. I would like to know how i can achieve this. I knw we can use web services for this, but i want to knw the procedure involved in doing this. I have mentioned few extractors which has to come from CRM system to BI/BW target system. Current we dont have these extractors in our BI/BW system. Also we dont have the connection to that particular CRM source. Please advice what has to be done for the above.
Extractors
1. 0CRM_FM_BPO
2. 0CRM_FM_FND
3. 0CRM_FM_FND_ATTR
4. 0CRM_FM_FND_EXPENSE_TYPE_TEXT
Thanks in advance

Hi,
First we need to create a RFC Connection between CRM To BW system. BASIS persons will create this connection.
[Connection between Source Systems and BW|http://help.sap.com/saphelp_nw70/helpdata/en/b2/e50138fede083de10000009b38f8cf/frameset.htm]
1.After that we can need to activate data sources in RSA5 in CRM system,
2.post processing in RSA6 in CRM.
3.Replicate source system in BW system.
those data sources will come to BW.
Do Business content activation in BW. After you can create Info packages and load data.
