I have an input in my jsf page like this
<html:inputText id="ResponseOK" value="#{bean.ResponseOK}" binding="#{bean.ResponseOKInput}" />
I want to get the value in a servlet (by request.getParameter ("ResponseOK")) when i click on a command button
<html:commandButton value="Valider" action="#{bean.callServlet}"/>
which call a function
public void callServlet()
{
String url = "http://localhost:8080/TestOne/Timers"; //servlet
FacesContext context = FacesContext.getCurrentInstance();
try {
context.getExternalContext().redirect(url);
}catch (Exception e) {
e.printStackTrace();
}
finally{
context.responseComplete();
}
}
Unfortunately, in my servlet the variable Ok , return only null
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
String Ok = request.getParameter("ResponseOK");// return null
System.out.println(timerOk);
}
thank you very much
In order for you to be able to get a property from the request, the input must have the name attribute:
<html:inputText id="ResponseOK" value="#{bean.ResponseOK}" binding="#{bean.ResponseOKInput}" name="ResponseOK"/>
UPDATE:
I'm not too familiar with the JSF framework but i think your problem is the action button.
This button is not a submit button so the value of the input is not being sent to the request.
When calling a GET request, you need to pass the parameter in URL itself, so you need the url to look like:
http://localhost:8080/TestOne/Timers?ResponseOK=value
So you need to transfer the value of the ResponseOK input to the callServlet
method.
Hope that helps.
