essayant de déployer l'applet java en utilisant jnlp

Question

je suis en train de déployer applet à l'aide jnlp

mon fichier jnlp:

<?xml version="1.0" encoding="UTF-8"?> 
<jnlp spec="1.6" codebase="http://localhost:8080/docRuleTool/appletjars/" href="dynamictree-applet.jnlp"> 
    <information> 
     <title>dynamictree</title> 
     <vendor>dynamic</vendor> 
    </information> 
    <resources> 
     <j2se version="1.6" href="http://localhost:8080/docRuleTool/appletjars/" /> 
     <jar href="dynamictree.jar" main="true" /> 
     <jar href="prefuse.jar" main="true" /> 
    </resources> 
    <applet-desc 
     name="dynamictree-applet" 
     main-class="com.vaannila.utility.dynamicTreeApplet.class" 
     width="1000" 
     height="1000"> 
    </applet-desc> 
    <update check="background"/> 
</jnlp> 

mon code applet:

<script src="http://www.java.com/js/deployJava.js"></script> 
<script> 
    var attributes = { id:'DynamicApplet', code:'jstojava.dynamicTreeApplet',} ; 
    var parameters = {jnlp_href:'./appletjars/dynamictree-applet.jnlp'} ; 
    deployJava.runApplet(attributes, parameters, '1.6'); 
</script> 

Mon javascript:

function showSelected(value){ 
alert("the value given from "+value); 
DynamicApplet.dieasenameencode=value; 
} 

Erreur que je reçois:

execption: The application has requested a version of the JRE (version 1.6) that currently is not locally installed. Java Web Start is unable to automatically download and install the requested version. This JRE must be installed manually..

Answer 1

Le problème est avec cette ligne:

<j2se version="1.6" href="http://localhost:8080/docRuleTool/appletjars/" /> 

Java Web Start essayera de télécharger Jre 1.6 de l'URL donnée dans l'attribut href. Version corrigée ci-dessous:

<j2se version="1.6" href="http://java.sun.com/products/autodl/j2se" />
