XML binding using JiBX

JiBX is a XML binding framework which binds XML to your java class.
XML binding is a 2 phase process:
1. JiBX uses binding definition to define the rule how conversion wil happen and modifies byte code of the class.
2. In phase 2 JiBX runtime does marshalling and un-marshalling of java objects to populate XML to java and java 2 XML.

Algorithm
  • Add following jar files to your lib directory from JiBX distribution
    1. bcel.jar (Byte Code Engineering Library used to change bytecode for the class)
    2. jibx-bind.jar (1,2 are used in phase I)
    3. jibx-run.jar
    4. jibx-extras.jar
    5. xpp3.jar (3,4,5 are used in phase II)
  • Modify java class using binding compiler (java -jar ../lib/jibx-bind.jar binding.xml)
  • Write code for marshalling and unmarshalling of java object

Example:



public void XML2Java2XML() {
try {
IBindingFactory bfact = BindingDirectory.getFactory(Customer.class);
IUnmarshallingContext uctx = bfact.createUnmarshallingContext();

Object obj = uctx.unmarshalDocument
(new FileInputStream("customer.xml"), null);
Customer customer = (Customer)obj;
System.out.print(customer.toString());

IMarshallingContext mctx = bfact.createMarshallingContext();
mctx.setIndent(4);
mctx.marshalDocument(obj, "UTF-8", null,
new FileOutputStream("customer2.xml"));

} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (JiBXException e) {
e.printStackTrace();
}
}

Password Strength Meter

Almost every web site provides password strength meter.
To make a strong password it should contain:
  • Sufficient length
  • Mixed case
  • Combination of numbers and Special characters

My password strength meter works on same line:

If password is of minimum length and same case it is a weak passwd

If password is min length mixed case and number normal passwd

if password is min length mixed case number and special char it is medium password

if password is above min length and combination of number and special char, it is strong passwd
