Different Versions of JWS Don't work with my jnlp - please help!!

Question

I had jdk1.5.0_14 installed with IIS serving a jnlp file that indicates the java version must be 1.5. I can download and run my application from a web page.
I installed jdk1.6.0_02. JAVA_HOME and the path environment variables both point to jdk 1.5.
I try to download the same jnlp via web browser. The JWS version indicates 1.6 but the java version correctly indicates 1.5. The problem, however, is that my app no longer runs - I get an error as my app tries to install some third-party tools that only run with Java 1.5 (the app can't run with Java 1.6 but I need Java 1.6 for other apps).
When I run this command "C:\Java\JDK1.5.0_14\bin\javaws 'C:\IIS\appdirectory\myfile.jnlp'" my application runs as it did previously.
Can anyone tell me if I can tell the system which version of JWS to use when running my jnlp file? I don't want to use the Java 1.6 version for my version that will be using JDK1.5.
Help would be greatly appreciated!!!

Thanks for your reply, however, I do have the j2se version tag set and when I have a Java Console window running along with my download the first line in the console window indicates it is using JWS version as 1.6 but the second line in the window indicates it is using JRE version as 1.5...I would like for both of them to be the same. So, I am getting the correct java version but something is happening with the JWS using the version from 1.6. Here's a snippet from my jnlp file:
<resources>
     <j2se version="1.5"/>
     <jar href="./ShipControlJavaPrototype.jar" main="true" />
               <jar href="./vecmath.jar"/>
     <jar href="./xith-tk.jar"/>
               <jar href="./joal.jar"/>
               <jar href="./log4j.jar"/>
     <jar href="./lwjgl.jar"/>
     <jar href="./vorbis.jar"/>
     <jar href="./xith_utilities.jar"/>
               <jar href="./swing-layout-1.0.jar"/>
               <jar href="./sqljdbc.jar"/>
     <nativelib href="joal-win.jar"/>
     <nativelib href="jogl-natives-win32.jar"/>
               <nativelib href="joystick.jar"/>
