Send the one textfield value as hidden parameter value to action classes
<s:form>
<td><s:textfield name="gadgetStatus.gdstatusId"></s:textfield></td>

//This is displaying some value like 100. this value goes to our action classes through below using hidden field. .
<s:hidden name="statusId" value="%{gadgetStatus.gdstatusId}"></s:hidden>
<td><s:submit value="update" action="updategadgetvehicle" method="upadateGadgetVehicle"></s:submit></td>
</s:form>

In ur Action classes just created setter and getter method s for varaible "statusId".

How to convert number to word in java, Number to Word

Just use String().subString() method and you can develop java code to convert number to word. Like 12345678 to
one Crore twenty three Lakh forty five thousand six hundred seventy eight.

import java.text.DecimalFormat;

public class NumberToWord {
public static void main(String[] args) {
System.out.println(convert(12345678));
}
private static final String[] tensNames = { "", " ten", " twenty", " thirty", " forty", " fifty", " sixty", " seventy", " eighty", " ninety" };

private static final String[] numNames = { "", " one", " two", " three", " four", " five", " six", " seven", " eight", " nine", " ten", " eleven", " twelve", " thirteen", " fourteen", " fifteen", " sixteen", " seventeen", " eighteen", " nineteen" };

private static String convertLessThanOneThousand(int number) {
String soFar;
if (number % 100 < 20){ soFar = numNames[number % 100]; number /= 100; } else { soFar = numNames[number % 10]; number /= 10;
soFar = tensNames[number % 10] + soFar; number /= 10; } if (number == 0) return soFar; return numNames[number] + " hundred" + soFar; }
public static String convert(long number) {
// 0 to 999 999 999 999
if (number == 0) { return "zero"; }
String snumber = Long.toString(number);
// pad with "0"
String mask = "000000000000"; DecimalFormat df = new DecimalFormat(mask); snumber = df.format(number);
int hyndredCrore = Integer.parseInt(snumber.substring(3,5));
int hundredLakh = Integer.parseInt(snumber.substring(5,7));
int hundredThousands = Integer.parseInt(snumber.substring(7,9));
int thousands = Integer.parseInt(snumber.substring(9,12));
String tradBillions;
switch (hyndredCrore) { case 0: tradBillions = ""; break; case 1 : tradBillions = convertLessThanOneThousand(hyndredCrore) + " Crore "; break; default : tradBillions = convertLessThanOneThousand(hyndredCrore) + " Crore "; }

String result = tradBillions;
String tradMillions;
switch (hundredLakh) { case 0: tradMillions = ""; break; case 1 : tradMillions = convertLessThanOneThousand(hundredLakh) + " Lakh "; break; default : tradMillions = convertLessThanOneThousand(hundredLakh) + " Lakh "; }
result = result + tradMillions;
String tradHundredThousands;

switch (hundredThousands) { case 0: tradHundredThousands = ""; break; case 1 : tradHundredThousands = "one thousand "; break; default : tradHundredThousands = convertLessThanOneThousand(hundredThousands) + " thousand "; }
result = result + tradHundredThousands;

String tradThousand;
tradThousand = convertLessThanOneThousand(thousands);
result = result + tradThousand;return result.replaceAll("^\\s+", "").replaceAll("file://b//s%7B2,%7D//b", " "); }

How to make Zip file using Java, Creating a ZIP file in Java

To run this tutorial
1. Create one folder src
2. Put test1.txt and test2.txt in src folder.
3. After run this code, you will get myZip.zip file in src folder.

import java.io.FileInputStream;

//String[] filesToZip = {"src\\test1.txt"};
String ZipedFileName = "src\\myZip.zip";
zipConversion(filesToZip, ZipedFileName);
}

public static void zipConversion(String[] files, String ZipedFileName){
byte[] buffer = new byte[1024];
try{
FileOutputStream outputFile = new FileOutputStream(ZipedFileName);
ZipOutputStream zipFile = new ZipOutputStream(outputFile);
for(int i=0;i<files.length;i++){
FileInputStream inFile = new FileInputStream(files[i]);
zipFile.putNextEntry(new ZipEntry(files[i]));
int length;
while ((length = inFile.read(buffer)) > 0) {
zipFile.write(buffer, 0, length); }

zipFile.closeEntry();
inFile.close();

XML to PDF tutorial

To transfer xml information to pdf (create pdf file from xml file)
FOP : Formatting Objects Processor is an open source Java API that can convert your XML data into reports in PDF format.
1. Download fop from apache binary version
2. Unzip file and copy any drive say c:\fop-0.95-bin and add this path to your system environment path.
3. student.xml (c:\pdf\student.xml)
4. student.xsl (c:\pdf\student.xsl)
5. use command (c:\pdf> fop -xml student.xml -xsl student.xsl -pdf student.pdf)
You will get one student.pdf file. Very easy

Student.xml
