Binding problem in .jsp page

M

Mongoose

Hi All,

I'm a new Java programmer and I'm working on a Java Server Faces
application. In one of my .jsp pages I'm doing some binding (code
shown below)

<h:graphicImage binding="#
{carstore.models.Jalopy.components.imageSmall}" />

and I'm getting this error:

"Cannot coerce type java.lang.Object to
javax.faces.component.UIComponent"

How do I best deal with the type mismatch??

Thanks,

Andy

You haven't shown us enough of the code. In particular, you haven't
shown us the part where the problem lies.

What is the backing bean code? The contents of the application
configuration resource file?

The message is telling you that the 'imageSmall' property is not a
pointer to a UIComponent.

Hi Lew,

Thanks for responding...here's the source code: carDetail.jsp - I put
an asterisk next to the lines where the error is occurring. Also,
this is a sample application found here:

am trying to make work in Rational Application Developer 7.5

I am not certain why you get the error, but I observe some potentially
relevant facts.

- 'carstore.models' is declared as a raw 'Map', which means that it
returns an element of type 'Object'. The same is true of the
'carstore.models.Jalopy.components' retrieved value. Something in the
retrieval of these values, probably the 'components' attribute, is not
keeping track of the actual run-time type. I would attempt adding
generics to the Java code, but I don't know if that will help.

- The project may include a 'CarBean' converter that would fix that,
but I didn't see it.

- The JSP code you show does not have the problem line you described:
<h:graphicImage
binding="#{carstore.models.Jalopy.components.imageSmall}"
/>

I don't have the answer, but perhaps these observations will help.

Hey Lew,

Thank you for your help . . . could you explain this line of code to
me?

binding="#{carstore.models.Jalopy.components.imageSmall}"

I have to admit I don't really understand what it refers to exactly???

Thanks!

I use the Java EE tutorial on Java Server Faces to help me on this
kind of thing:
<http://java.sun.com/javaee/5/docs/tutorial/doc/bnaph.html>

Step by step:

The 'binding' attribute links the control (e.g., command button) to a
JSF component, in your case a graphicImage.

That means that the Expression Language (EL) expression "#
{carstore.models.Jalopy.components.imageSmall}" needs to evaluate to
an appropriate JSF component on the Java side.

<http://java.sun.com/javaee/5/docs/tutorial/doc/bnahq.html>
<http://java.sun.com/javaee/5/docs/tutorial/doc/bnaqm.html#bnaqp>

In EL, the "dot" notation does a couple of things.

One, it invokes a getter method or a setter method for an attribute,
thus
"carstore.models"
invokes the 'getModels()' method of the 'carstore' object defined in
the faces-config.xml.

Otherwise, it acts as an array or Map dereferencer, same as the square
brackets '[]' notation, so
"carstore.models.Jalopy"
looks up the Map value for which 'Jalopy' is the key.

So you look at the source code dot by dot, looking for either a get
method or a Map key that corresponds to the name in the dot notation.

carstore
- backing bean defined in faces-config.xml
models
- getModels() method of that bean
Jalopy
- key to a Map, specifically the Map returned by getModels()
components
- a collection or getter in the value object associated with
'Jalopy', I forget which
imageSmall
- a value retrieved from 'components'

That last value, 'imageSmall', must be a reference to a JSF component
because you used the 'binding' attribute.

As an aside, I wonder why the example at that link declares a no-arg
constructor given that there is no other constructor and nothing done in the
constructor body.[/QUOTE]

Interesting question. For study, I recall writing explicit no-arg
constructors until I was comfortable with the equivalent default [1]:

class Parent extends Object {
public Parent() { super(); }
}

class Child extends Parent {
public Child() { super(); }
}

The example cited above appears to go only halfway, showing the
constructor itself but omitting the implicit superclass constructor
invocation.

Of course, modest indentation and less glitz would improve readability
more.

I've been out of the office . . . just wanted to say thanks to Lew and
all others that responded to my question. You've all been very
helpful . . .
