Which webstart version is starting my app ?? [confused...]

Question

I'm a bit confused, but maybe someone can help me out.
This is the situation:
-> Installed on my Windows machine:
* JRE 1.5.0 (of JDK, that's the same)
* also a JRE 1.4.2_07
* a firewall
* IE or firefox browser (with mime-type "application/x-javajnlp-file" mapped correctly).
-> a webapp on some (web)server (also with mime-type correctly configured). The webapp contains the necessary resources (jars, jnlp file).
-> here's the jnlp file:
<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="1.0+" codebase="http://server1/someapp" href="someapp.jnlp">
<information>
<title>Some App</title>
<vendor>Sun Microsystems, Inc.</vendor>
<offline-allowed/>
</information>
<resources>
<jar href="app1.jar"/>
<j2se version="1.4.2*" href="http://java.sun.com/products/autodl/j2se"/>
</resources>
<application-desc main-class="myapp"/>
</jnlp>
-> while starting the app, i notice that, i guess the 1.5 java webstart engine handles this app (it seems to be 1.5 stuff when i look at the layout of the dialog). BUT (!) the only traffic passing my firewall is that of the following application: .../jre1.4.2_07/bin/javaw.exe. So, th� question is: "what "java web start - version" (*) is actually running my code ??
(*) i'm not talking about the JRE. That should be 1.4.2_07, since i asked, in the jnlp, for my code to run in a 1.4.2* JRE. But there must be some javaws active, f.i. for examining my app jars on the webserver.
P.S. when i change the <j2se version ...> into 1.5+, the request i intercept then is actually coming from jre1.5.0_05/bin/javaw.exe (which i expected in the first place).
help.

Answer 1

Yes - in this case you run webstart 1.5.0 with jre 1.4.7
the jnlp mime type is setup by the windows installer when installing a jre that is the latest on the system. (it actually points to <windows dir>/system32/javaws.exe, which is set up as the latest version installed)
