<j2se version="1.4+"
href="http://java.sun.com/products/autodl/j2se" />

what does the + mean? Is it some sort of wildcard for "the current
version"? any 1.4.* ?

Is there a tool to validate your jnlp file syntax or to warn you if
you left anything important out?

Any 1.4 version, (+) 1.5 (, 1.6..),
Excluding any version with a '-'.
From..
<http://java.sun.com/j2se/1.4.2/docs/guide/jws/developersguide/syntax.html#resources>
" <j2se version="1.4+">
would not consider an installed 1.4.1-ea or
1.4.2-beta JRE as a match for the request"

I went hunting for a more specific reference to the '+'
(which I had always inferred to mean 'installed JRE'>='number stated')

..the JNLP spec. HTML version, section 1.4.
(where's the on-line version?)/JNLP/jnlp-spec-1.5/overview.html#example

"
(section) 1.4 An Example
...
<j2se version="1.3+"/>
...Java 2 platform, version 1.3 or _higher_ is required..
"

There, settled!

I find JAWS itself gives you some pretty explicit messages.
You might find you can call it from code, I have not tried
that.
