pcflow utility

HI all,

I try to find an example that shows the utility of pcflow pointcut. Do you think that the following example is good?

Example: Adding security mechanism to all the getConnection calls that are in the predictive control flow of a Replace SQL execution query.  The advice and the java program where to incorporate the advice ae given in the following:

Aspect Secure {
    pointcut executQuery(String s): execution(*.executeQuery(...)) && args(*,s);
    pointcut getConnectionWithReplace(String s,Properties p): call(*.getConnection(...))&& args(*,p) && pcflow(executQuerywith(s))&& if(isFirstSubstring(s,"REPLACE"); 
    Before(Properties p, String s): getConnectionWithReplace(p,s)(): { 
                p.put("securityMechanism", new String("" + com.ibm.db2.jcc.DB2BaseDataSource.USER_ONLY_SECURITY + ""));
      }
}


import java.sql.*;

import com.ibm.db2.jcc.*;

public static void main(String[] args) {

     ...

Properties properties = new Properties();

 properties.put("user","db2adm");

 properties.put("password", "db2adm");

String url =..

....

Connection con =DriverManager.getConnection(url,properties);

Statement st = db2Conn.createStatement();

String query = "REPLACE... "

 ResultSet resultSet = st.executeQuery(query);

....
