jsp usebean struts

i'm graceful new during take easy me.

the formula i'm perplexing work is:

<jsp:usebean id="ejd" class= "moverdetailform" scope="application"/>
<jsp:setproperty name="ejd" property="empfdjoiningdate" param="empfdjoiningdate" />

<% twine empfdjoiningdate = ejd.getempfdjoiningdate();
out.print("please work" + empfdjoiningdate); %>     

empfdjoiningdate returning 'null' i assume cant moverdetailfom.java?

this does exist

public category moverdetailform extends abstractcandidateform {

private twine empfdjoiningdate;

/**
 * @return advantage empfdjoiningdate.
 */
public twine getempfdjoiningdate() {
    relapse empfdjoiningdate;
}
/**
 * @param empname empname set.
 */
public vacant setempfdjoiningdate(string empfdjoiningdate) {
    this.empfdjoiningdate = empfdjoiningdate;
}

any suggestions many appreciated. i'm stuck!

thanks
