Sorry for the OT post but the java forum was unresponsive.
How do you get
the size of a collection class in the JSTL EL?
You can do it with jsp expressions like:
Thanks David. Do you really think I'm not using struts :-) ?

Thanks Craig. I realize that it doesn't work because of the naming issue
but I was wondering if there was an easy way
It should also be relatively painless to use a composition/delegation approach.
public class CollectionBean {
private Collection c;
public int getSize() {
return this.c.size();
}
public void setCollection(Collection c) {
this.c = c;
}
public Collection getCollection() {

That's pretty much what I did except you can only set the internal
collection in the constructor. It's an elegant solution that should
probably (in some form) be included in a larger library.

What is a DynamicProxy? We may be talking about the same pattern with

But applying a proxy to this scenario seems like overkill. Wouldn't you have to
do something like the following:
public interface CollectionInfo {
public int getSize();
}
public class CollectionHandler implements
14 matches
