How we can create shape in excel using jsp

create shape in excel using jsp

In this program we are going create a sheet and then after we create a shape. At excel sheet e.g. we are creating line in this example. To create shape we use setShapeType() in this method we are passing the shape type as an arguments.

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_LINE to create a simple line.
The code of the program is given below:

      shape1.setShapeType(HSSFSimpleShape.OBJECT_TYPE_LINE);

      FileOutputStream fileOut = new FileOutputStream

    ("c:\\excel\\createShape.xls");

      hwb.write(fileOut);

      fileOut.close();

  out.println("Your excel file has been generated");
