The j2se element specifies what Java 2 SE Runtime Environment (JRE)
versions an application is supported on, as well as standard
parameters to
the Java Virtual Machine. If several JREs can are specified, this
indicates
a prioritized list of the supported JREs, with the most preferred
version
first. For example:
<j2se version="1.3" initial-heap-size="64m"/>
<j2se version="1.4+"/
Thank you, Scott. At last, someone who's read the JNLP spec. I've
tried
to make this point several times, apparently without success:
a JNLP file is not limited to a single J2SE version.
Perhaps citing the spec will finally settle this.
....
So assuming I have the syntax correct as shown...
1. If the above has been tried, then it should work.
2. If it has not been tried, then it should be tried.
I tried it this morning. The syntax Scott proposed does indeed do
the job.
You can verify it yourself by doing this:
-- Start with a 1.4.2 system, and then install 1.5.
-- Run your application with the j2se tags as shown
--> See that it picks 1.5.0.
-- Now, move aside 1.5 (into the parent directory, for example.)
-- Run the app again
-- It launches with 1.4.2.
You could try testing with 1.4.2 first, but then you don't have the
preferred VM list that gets generated by using Cache Viewer, so it's
not the same test.
Either ordering of the preferred VM versions in Java Preferences will
pick 1.5 first, if available, then 1.4.
