Conversion Error setting value 'xyx for 'null Converter'. in my page

[Yahya Arshad]

i am facing a problem that i have bind a component in managed bean

<h:panelGroup>
<h:inputText id ="fName" value="#{registerReader.fName}" required="true">


</h:inputText>
<f:verbatim><br/></f:verbatim>
<h:message for="fName" styleClass="errors"/>

before compenent binidng i was using value binding but my basic purpose was to put entered value in jsf page and submit them into database but by value binding null values were going so i tried for component binding but now it is giving two errors

<h:panelGroup>
<h:inputText id ="fName" value="#{registerReader.fName}" required="true">

one is

Conversion Error setting value 'xyx for 'null Converter'.

but if i use any convertor this error disappeares but another error appear

pages/reader/registration.jsp(40,0) '#{registerReader.fName}' Cannot convert 5555 of type class java.lang.Long to class javax.faces.component.html.HtmlInputText

if i try custom convertor which convert it user input to string this error becomes

	}





	public void setfName(HtmlInputText fName) {
		this.fName = fName;
		
	}





public String submitDB(){
	firstName = fName.getValue().toString();

	
	String query="INSERT INTO onlinelibrary.language (languageid, booklang) VALUES (7, "+"\'"+firstName+"\');";
	DBConnection db = new DBConnection();
