i have scenario unable access variable present in action class in dao. struts framework ejb , old code jsp written in java class file. reverse side code display jsp comes java , ejb class files interface. particular variable in action class obtained request variable. want use variable in dao class. can think of 2 options. set in form , use form in dao , value. wouldnt work form reinitialised in method used. 2nd set them in session or request value null in dao.

how else can done. want access variable action class in dao. please suggest. thanks!

use overloaded method

say have

public void save(string firstname, string secondname){     jdbc.save(firstname, secondname); } 

but need new parameter! create same method , this

public void save(string firstname, string secondname, string userid){     //this keep backward compatibility     if(userid == null){         //whatever in older method, in case simple save         jdbc.save(firstname, secondname);     } else {         jdbc.save(firstname, secondname, userid);     } }  public void save(string firstname, string secondname){     save(firstname, secondname, null); }
