ServletContext context = request.getServletContext();
getServletContext() is available from HttpServlet class that your servlet extended. You can invoke the method as if it were defined in your own servlet class
ServletContext context = getServletContext();

I am having single column in excel sheet which I want to replicate in Jython scripting and place it in adjacent column.The Content of the Column is as in the Pic below
from jxl import *
from jxl.write import *
from java.io import File
workbook = Workbook.getWorkbook(File("$(TargetFolder)\Book2.xls"))
targetWorkbook = Workbook.createWorkbook(File("$(TargetFolder)\Book2.xls"),
workbook)
sheet = targetWorkbook.getSheet(0)
columnIndex = 0
rowCount = sheet.getRows()
for i in range(rowCount):
row = sheet.getRow(i)
content = row[columnIndex].getContents()
rc.logMessage("Content -> " + content)
wc = sheet.getWritableCell(1,i)
newLabel = Label(1,i, content)
sheet.addCell(newLabel)
targetWorkbook.write()
targetWorkbook.close()
workbook.close()

How to get Total Columns Returned by Query
ResultSet rs = stmt.executeQuery(strSQL); ResultSetMetaData rsmd = rs.getMetaData(); int columnsNumber = rsmd.getColumnCount();
How to get Column Name from Query
ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM TABLE2");
ResultSetMetaData rsmd = rs.getMetaData();
String name = rsmd.getColumnName(1);
How to get Column Count from Query and Loop Through That
ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM TABLE2");
ResultSetMetaData rsmd = rs.getMetaData();
int columnCount = rsmd.getColumnCount();
// The column count starts from 1
for (int i = 1; i < columnCount + 1; i++ ) {
String name = rsmd.getColumnName(i);
// Do stuff with name
}
To Find a Column with particular Name
ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM TABLE2");
rs.getString(rs.findColumn("fullname"));
How to get List of Column Names from Query and Store it in a Array
ResultSetMetaData meta = resultset.getMetaData(); Integer columncount = meta.getColumnCount(); int count = 1 ; String[] columnNames = null; while(columncount <=count) columnNames [i] = meta.getColumnName(i); System.out.println (columnNames.size());
