1. Create a New Workspace and Project
File > New > General > Workspace Configured for Oracle Applications
File Name – PrajkumarImportxlsDemo
Automatically a new OA Project will also be created
Project Name -- ImportxlsDemo
Default Package -- prajkumar.oracle.apps.fnd.importxlsdemo
2. Add JAR file jxl-2.6.3.jar to Apache Library
Download jxl-2.6.3.jar from following link –
http://www.findjar.com/jar/net.sourceforge.jexcelapi/jars/jxl-2.6.jar.html
Steps to add jxl.jar file in Local Machine
Right Click on ImportxlsDemo > Project Properties > Libraries > Add jar/Directory and browse to directory where jxl-2.6.3.jar has been downloaded and select the JAR file
Steps to add jxl.jar file at EBS middle tier
On your EBS middile tier copy jxl.jar at $FND_TOP/java/3rdparty/standalone
Add $FND_TOP/java/3rdparty/standalone\jxl.jar to custom classpath in Jser.properties file which is at $IAS_ORACLE_HOME/Apache/Jserv/etc
wrapper.classpath=/U01/oracle/dev/devappl/fnd/11.5.0/java/3rdparty/stdalone/jxl.jar
Bounce Apache Server
3. Create a New Application Module (AM)
Right Click on ImportxlsDemo > New > ADF Business Components > Application Module
Name -- ImportxlsAM
Package -- prajkumar.oracle.apps.fnd.importxlsdemo.server
Check Application Module Class: ImportxlsAMImpl Generate JavaFile(s)
4. Create Test Table in which we will insert data from excel
CREATE TABLE xx_import_excel_data_demo
( -- --------------------
-- Data Columns
-- --------------------
column1 VARCHAR2(100),
column2 VARCHAR2(100),
column3 VARCHAR2(100),
column4 VARCHAR2(100),
column5 VARCHAR2(100),
-- --------------------
-- Who Columns
-- --------------------

last_updated_by NUMBER NOT NULL,
creation_date DATE NOT NULL,
created_by NUMBER NOT NULL,
last_update_login NUMBER
);
5. Create a New Entity Object (EO)
Right click on ImportxlsDemo > New > ADF Business Components > Entity Object
Name – ImportxlsEO
Package -- prajkumar.oracle.apps.fnd.importxlsdemo.schema.server
Database Objects -- XX_IMPORT_EXCEL_DATA_DEMO
Note – By default ROWID will be the primary key if we will not make any column to be primary key
Check the Accessors, Create Method, Validation Method and Remove Method
6. Create a New View Object (VO)
Right click on ImportxlsDemo > New > ADF Business Components > View Object
Name -- ImportxlsVO
Package -- prajkumar.oracle.apps.fnd.importxlsdemo.server
In Step2 in Entity Page select ImportxlsEO and shuttle it to selected list
In Step3 in Attributes Window select all columns and shuttle them to selected list
In Java page Uncheck Generate Java file for View Object Class: ImportxlsVOImpl
Select Generate Java File for View Row Class: ImportxlsVORowImpl -> Generate Java File -> Accessors
7. Add Your View Object to Root UI Application Module
Right click on ImportxlsAM > Edit ImportxlsAM > Data Model >
Select ImportxlsVO and shuttle to Data Model list
8. Create a New Page
Right click on ImportxlsDemo > New > Web Tier > OA Components > Page
Name -- ImportxlsPG
Package -- prajkumar.oracle.apps.fnd.importxlsdemo.webui
9. Select the ImportxlsPG and go to the strcuture pane where a default region has been created
10. Select region1 and set the following properties:
