jsp:useBean question

for instance, if we have this:

<jsp:useBean nameBean="X" class="Y" />

is it supposed to be a compile OR runtime error?

Tks.

hi,
this looks like a syntax error and hence i think it should be a compile time error. Please correct me if i am wrong

Hi Roy,

Actually it�s a "translation time error" i gues!

The container gets this error at translation phase, and the ".class(servlet)" is not generate.

Please folks, does this sentence make sense?

" **Every request-time** expression has a **translation time error** regarding sintax errors???**"


Tks.

Hi,

I guess if there are not at least a class and a id parameter in the <jsp:usebean >, the container is not able to translate the tag into the Servlet code that declares and possibly defines the corresponding javabean: they are the required info defining the class and name of the object => translation error sounds logical in that case.

do you also get an error when you specify id, class and an illegal stuff like beanName ?

(yeah, I could try it myself, but it's midnight here...)


Cheers,

Hi,

It is translation time error. The container validates all action elements at the translation time for the required attributes and syntax.

Thanks
