Someone told me JDOM have problem in parsing and saving string value, so now I am working on jaxb. But please help me where I'm going wrong.

In jsf page question is my controller .

<h:outputText id="correctAns" value="#{question.questionModel.correctAnswer}" />  

when I am going to print this I got same.

But when i am save from inputext i got junk character when i am going to print in my controller. In my jsp page i have add <%@ page pageEncoding="UTF-8" %>

<h:outputText id="correctAns" value="#{question.questionModel.correctAnswer}" />
