reverse engineer an xquery

gistfile1.txt

steps
1.Create a simple java program that either call or embed an xquery
2.Input the java program into Altova UML/any open source available for java  for creating sequence diagram

import javax.xml.xquery.*;
import net.cfoster.sedna.xqj.SednaXQDataSource;

public class SimpleQuery
{
  /**
	 * 
	 * @param symbol
	 */
	public double GetBookPrice (String symbol) throws XQException, XQException
  {
    XQDataSource xqs = new SednaXQDataSource();
    xqs.setProperty("serverName", "localhost");
    xqs.setProperty("databaseName", "test");

    XQConnection conn = xqs.getConnection("SYSTEM", "MANAGER");
    XQExpression xqe = conn.createExpression();

    String xqueryString =
    "for $x in doc('books.xml')//book return $x/title/text()";

    XQResultSequence rs = xqe.executeQuery(xqueryString);

    while(rs.next())
      System.out.println(rs.getItemAsString(null));

    conn.close();
  }

/**
	 * 
	 * @param symbol
	 */
	public double GetBookDetails (String symbol) throws XQException, XQException
  {
    XQDataSource xqs = new SednaXQDataSource();
    xqs.setProperty("serverName", "localhost");
    xqs.setProperty("databaseName", "test");

    XQConnection conn = xqs.getConnection("SYSTEM", "MANAGER");
    XQExpression xqe = conn.createExpression();

    String xqueryString =
    "for $x in doc('books.xml')//book return $x/title/text()";

    XQResultSequence rs = xqe.executeQuery(xqueryString);

    while(rs.next())
      System.out.println(rs.getItemAsString(null));

    conn.close();
  }
}
