map referenceData

[fanfaron]

Hi,

I know the method referenceData return a map that contains objet
that I can use in my jsp page. things like a list
that I can use to make a drop down list.

But I want to pass a list in that map to a custom tag.

And I've been trying for month and I can't find a solution

I can use EL (${}) to construct my drop down, But I have
13 of them in a form, So my jsp is quite big, and I don't like that.

I have a custom tag that builds a drop down, but I just can't pass
the list to it. Because I cannot access it easily. How does
jstl access it??? simply with ${listJob}???

what does ${listJob} means really in ??? Which bean does it use??
How this introspection works???

I was trying to use

<jsp:useBean id="listJob" scope="request" class="java.util.List" />
But it doesn't work.

Have someone did that?

It depends on how you wrote your custom tag. Your tag is responsible for dereferencing ${xxx}. For an example, check the Spring tags' source code. Spring provides a nice utility for working with JSTL variables.

On a side note, you should really use a JSP 2.0 tag file. They are much easier to write than standard Java tags, and can handle the dynamic JSTL parameters automatically.

Thank you very much for indicating me about
existance of tag file,

I didn't even know their existance.

I found a interesting article on OTN(oracle technology network)
