Creating JAXB classes through ANT Build script

It's just a matter of two steps.....
1) first need to create taskdefination of xjc class of sun.
2) Then need to generate the source code from schema  by creating a task in ant file.
     After generating source code need to do compile task in ant.

Finally JAXB classes are ready.....


Step one:

creating a taskdef of xjc



Step Two:

Parsing the string by using delimeter in java

import java.util.HashMap;
import java.util.Map;


public class StringParsingDemo {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub

String url = "http://localhost:8080/PrismWeb/REPORT/REPORTS_AggSectorRpt/ACCOUNT/$$BENCHMARK_CD$$/DATE/$$DATE$$/XML/TREE";
        String delims = "[/]+";

String[] tokens = url.split(delims);

   Map mapecm = new HashMap();
for(int i=0; i
String value = tokens[i];
String key = null;
if(value.contains("$") && i > 0 ){
key = tokens[i-1];
mapecm.put(key, value);
}
}
 System.out.println("Mapis " + mapecm);

}
