Tim:
Thanks for tolerating me with these simple
questions.
I tried your method getProperty). But still I am
having problems.
This is what I want to do. I have a simple java
bean. I have a String variable x. I want to print the value of that x in the
browser using JSP.
This is what I tried:
1. I wrote a getter public String getX()
in the bean and tried to access the method. The error was: No such method
found.
2. I tried the getProperty in the JSP page. Error:
no such property in Bean.
Where am I wrong.
I am also going thru the link you sent me.
Thanks
/KK
