Debugging JSF pages ... how to make it suck less ?

[Alex Nedelcu]

Although I like working with JSF, there is something really annonying ... the error messages are sooooo ugly.
I would like something like the ASP.NET default error handler, where a nice message, with the error details, is displayed.

Really, only a minor typing error and I get this ? ....

org.apache.jasper.JasperException: javax.servlet.jsp.JspException: Error getting property 'namess' from bean of type beans.Form
org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:510)
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:375)
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314)

The case above is fortunate as you can figure out what happened, but I bumped into cases where I couldn't simply tell what's going on.

Does anyone know of a solution to this ?

if you add the facelets library to your project, the exception might look like this one:

That's nice, thanks.

I've heard about Facelets.
And by using it, I have to wonder ... how production ready is it ?

Do you have experience with Facelets ?
What kind of problems have you experienced with using it ?
