Java web start - Version problems

I've decided to make my app java web start, i prepared the .jar file and .jnlp. Here is .jnlp:

<?xml version="1.0" encoding="UTF-8"?>
<jnlp spec="1.0+" 
    codebase="http://www.mypage.com/jar/" 
    href="BoxChat.jnlp">
    <information>
        <title>BoxChat</title>
        <vendor>Kitty</vendor>
    </information>
    <resources>
        <!-- Application Resources -->
        <j2se version="1.6+"
              href="http://www.mypage.com/jar/"/>
        <jar href="chat.jar" main="true" />

    </resources>
    <application-desc
         name="BoxChat"
         main-class="chat.class"
         width="320"
         height="240">
     </application-desc>
     <update check="background"/>
</jnlp>

It crashes and says that i have no java 1.6 installed, but im SURE that i have it. What is the problem? Thanks for any replies.

Looks like the problem is with the below line:

<j2se version="1.6+" href="http://www.mypage.com/jar/"/>

You need to specify the vendor url only if you want to request a specific JRE version for example 1.4.2_04. Remove the href attribute and re-try.

When you install java usually there are two steps. The first is jdk and when it is finished then it asks you whether you would like to install jre. And webstart requires JRE installed correctly. So I would simply sujest to install it again and make sure that you perform the second step (jre).

Look through the tips in Java Web Start - Runtime Versioning. Look particularly for references to the JNLP Runtime Settings dialog.
