creating oval in excel using jsp

                         

In this program we are going create a sheet  and then after we create a oval. 

Code description 
The package we need to import is java.io.*,java.util.* ,org.apache.poi.hssf.usermodel.HSSFSheet,org.apache.poi.hssf.usermodel. HSSFPrintSetup, org.apache.poi.hssf.usermodel.HSSFPatriarch,org.apache.poi.hssf.usermodel.HSSFClientAnchor,org.apache. poi.hssf.usermodel.HSSFSimpleShape and org.apache.poi.hssf.usermodel. HSSFWorkbook.
 
The org.apache.poi.hssf.usermodel.HSSFPatriarch extends java.lang.Object and implements HSSFShapeConatainer.The patriarch is the tope level container for shapes in a sheet. It acts as a container for shapes and groups. 
The  org.apache.poi.hssf.usermodel.HSSFClientAnchor class is public class. The HSSFClientAnchor extends HSSFAnchor.A client anchor is attached to an excel worksheet. It anchors against a top-left and buttom-right cell. 

There are two constructors:
 HSSFClientAnchor(): 
This is used to creates a new client anchor and defaults all the anchor positions to 0. 

HSSFClientAnchor(int dx1, int dy1, int dx2, int dy2, short col1, int row1, short col2, int row2): 
This is used to creates a new client anchor and sets the top-left and bottom-right coordinates of the anchor. 

 The org.apache.poi.hssf.usermodel.HSSFSimpleShape class extends the  HSSFShape and the HSSFSimpleShape  class is used for a simple shape such as a line, rectangle or oval. 

We can set  various borders and set various color of the borders.
The method used in this example shift row

setShapeType(HSSFSimpleShape.OBJECT_TYPE_LINE):
This method is used to set the shape we can pass the following  statice parameters of HSSFSimpleShape:
static short OBJECT_TYPE_LINE 
static short OBJECT_TYPE_OVAL
static short OBJECT_TYPE_PICTURE
static short OBJECT_TYPE_RECTANGLE
 
In this example we are using  OBJECT_TYPE_OVAL  to create a simple oval.
 The code of the program is given below:

  HSSFSimpleShape shape1 = patriarch.createSimpleShape(a);
  shape1.setShapeType(HSSFSimpleShape.OBJECT_TYPE_OVAL);
  FileOutputStream fileOut = new FileOutputStream
(
"c:\\excel\\makingOval.xls");
  hwb.write(fileOut);
  fileOut.close();
  out.println("Your excel file has been generated");
    catch Exception ex ) {   }%>

The output of the program is given below:
