Applet type JNLP does not open with OpenwebStart.

[seliinozkan]

I have 2 JNLP files, one of them is applet type and the other is application. However, those of applet type cannot be opened with openwebstart.

The main class of the applet is JHello2JavaExample which implements JApplet.

After the applet's start invoked, I noticed that the applet is closed directly by openwebstart. This situation does not apply to application types, I can open them.

Any Idea to get it working?

When I try with IcedTeaWeb 1.8.8, I can open this GUI.

Applet type JNLP:

  <resources>
        <!-- Application Resources -->
        <j2se version="1.8+"
            href="http://java.sun.com/products/autodl/j2se" />
        <jar href="clientJars/testApplet.jar" download="eager"/>
    </resources>
    <applet-desc 
         name="Hello Applet"
         main-class="test.JHello2JavaExample"
         width="300"
         height="300">
    </applet-desc>
