Booleans as properites

[daleth]

I feel like I must be missing it, but I really can't find it. Is there is a simple mechanism, within the XML configuration file, to create a bean of type java.lang.Boolean with a given true/false value? Something like <true/> or <false/> in the same vain as <null/>.

I know Spring would convert "true" in Boolean("true") if it can get at the argument type information but the case I ran into were non-typed collections (in my case, a map) where a value needs to be a Boolean. So, Spring wasn't able to figure out what the type was supposed to be.

If such <true/> and <false/> tags don't exist yet I'd like to recommend adding them, even if it's just in the util schema? Thanks!

<util:constant static-field="java.lang.Boolean.TRUE/>
<util:constant static-field="java.lang.Boolean.FALSE/>

Thanks, that's what I was looking for.

I have been going through the Documentation on the Spring .org website, but did not find anything about using these custom tags. Nevertheless, I feel they offer a variety of functionality.

Can you tell me what DTD do I import to use these <util: tags?
Where can I read up on <util: and other custom tags?

Thanks.

There's some information on this here.

1. They are described in the Spring Reference (2.x), see e.g. Appendix A.2.2 in the Spring 2.0.7 Reference.

2. You shall give up DTD completely and use XML Schema instead, see the same appendix for details.

3. If you for some reasons can not give up DTD or have to use Spring 1.x then you may use older syntax described in the same section under title "Before ..."

Thank you.

And theres some here as well outlining the exact util and the XSDs involved, just found it out.
