Question

I new to web-start and We are using exe4j to create executable from One-jar. In-order to make a “web start version” of our application I am trying to lunch One-JAR using web start with the specified Main-Class but I am getting the following error –

 java.security.AccessControlException: access denied (java.util.PropertyPermission one-jar.main-class read)
    at java.security.AccessControlContext.checkPermission(Unknown Source)

JNLP contains —

    <?xml version="1.0" encoding="UTF-8"?>
<jnlp spec="1.0+" codebase="" href="">
    <information>
        <title>Applet Takes Params</title>
        <vendor>Protype example</vendor>
    </information>
    <resources>
        <!-- Application Resources -->
        <j2se version="1.5+"
              href="http://java.sun.com/products/autodl/j2se"/>
        <jar href="Application.jar" main="true" />
    </resources>
    <application-desc main-class="com.simontuffs.onejar.Boot">
  </application-desc>
   <update check="background"/>
</jnlp>

I am trying to launch a Application.jar directly and com.simontuffs.onejar.Boot is the main class specify for JAR. I am also found this link that says we can not launch One-Jar with web-start. please help.

Answer 1

access denied (java.util.PropertyPermission one-jar.main-class read)

A web start app. can access any property if it declares all-permissions. If it is sand-boxed, it can only access properties prefixed with jnlp & some other JRE properties that are considered ‘safe’.
