It's gonna use this Java Bean to craft the sentance.

package whatever;

public class Lentil {
private String owner;
private String possessions;
public void setOwner(String owner) {
this.owner = owner;
}
public void setPossessions(String possessions) {
this.possessions = possessions;
}
public String getSentance(){
return "My " + owner + " has " + possessions + ".";
}
}
If the values are left off of the set tags in the .jsp page, Java will attempt to find request variables of the same names as the variables to set and hand in their values to the Bean. The presence of both a request variable and an inline value seemed to cause Java to blow up when I experimented with it.
