I followed your advice. In the Bean.java, I did the
following:
private String username = "natalie";
public String getUsername() {
return this.username;
}
public void setUsername(String username) {
this.username = username;
}
and I compiled all the relevant classes, re-run the
application, the FindEditorData.java writes out the
following in the browser:
The process did not complete. Details should follow.
name=natalie; kn=journal_category; kv=null
Now, the question is why the Bean.java does not pick
up the value of the hidden field 'username' from my
JSP while successfully picks up the value of the other
hidden field 'keyName'.
There is some data processing activities going on in
the FindEditorData.java:
String username = getUsername();
EditorService service = new EditorService();
String value = service.findEditorData( username );
The above data accessing codes had been tested outside
the environment of the application (the codes did what
I expected them to do without problem) before they
were integrated into the application.
