Retrieve the Value of a Bean Property in a Servlet

[JiaPei Jen]

In my servlet, I delegate a method

findEditorData( username );

to a business logic class EditorService.java. The findEditorData( username ) searches the database and populates the properties of a JavaBean (EditorBean.java)

        EditorService service = new EditorService();
        EditorBean editor = service.findEditorData( username );

I got a NULL when tried to retrieve the value of one of the Bean's property in this servlet:

        String category = editor.getKeyValue(); //what is wrong with this statement

But, it is not possible. Because I had no problem to wrap the EditorBean in a session object:

        HttpSession session = request.getSession();
        session.setAttribute( "editor", editor );

and then passed the session object to a JSP, got the property from the session object, printed out the value of this property, which was not a null.

the thing to do is to look in your work folder (eg tomcat/work) and find the code for getting the bean in a servlet from the JSP you wrote that accessed it

for getting the bean in a servlet from the JSP you wrote that accessed it.

In my servlet, I tried to get one of the properties of the bean - I got a null.
I am not trying to, and I do not want to, get the bean from the JSP. I simply tested to get one of the properties of the bean in a JSP - it was not a null.

Without seeing the rest of your servlet code I can't be sure, but are you sure it's not a "scope" problem? Check that you don't have two variables called "editor" in your JSP, and that you have definately initialised the editor variable before you use it.
