Hi Tim, formatting in the sense i meant about the bold and italicized content. I am not sure when i store a bolded and Italized text(of String data type as you suggested) on to varchar will it be same or not.

As suggested i will implement the way you suggested rtf text stored in a String(Java Side) and the same in database (either varchar or clob). Hope it works successfully.

Thanks for reply tom.

The scenario goes like this. From the client side(EXTjs) i will be collecting the text sent in RTF. I need to first grab with some data type that supports RTF in java and then store the same in database and retieve it( without affecting the format of the text). Will it be possible using Strings? If i store strings in DB as varchar, the entire format of rich text will be lost rite?

I had thought of file handling by capturing the text from client in a RTF file and then storing the file as a BLOB object in DB. But the idea is rejected here.
Please help.

Hi All,

I have a basic question. I want to know how to store rich text content in java. Is there any specific data type to hold such data without affecting the original data. I should be in a position to store the rich text content on to some variable(of data type that supports RTF) and retrieve it when ever required.

We don use swings here. Also this requirement should be met without file handling. Please help me in this regard.

Hi All,

I am trying to develop a quiz application based on MVC architecture using JSP and servlets. I have a frame where left side displays the questions and right side displays the set of buttons(total no of questions). When i click on "2" button, its not overwriting the left pane, instead its appending with the left one and displaying 1,2 questions. When i click on 3rd button, the left pane is not getting overwritten. In my servlets i am using request Dispatcher to forward to Jsp which will display the frame. Can you please hel out here. Below is my code

//Frame displaying left side question and right side buttons
