JNLP as a Applet in HTML page

Question

I'm trying to run my JNLP within an HTML page, but the java plugin does not run the JNLP, runs only the Applet.

Here is my code:

<applet width="800" height="500" codebase="http://127.0.0.1:8888/applets/"
    code="br.com.app.server.utils.CompatibilityApplet"
    archive="CompatibilityApplet.jar">
            <param name="jnlp_ref" value="http://127.0.0.1:8888/applets/testehellojws.jnlp">
</applet>

Thanks.

[EDIT]

An example:

http://java.sun.com/javase/ja/6/ea/6u10/plugin2/jnlp/CompatibilityApplet.java

<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="6.0+" codebase="http://127.0.0.1:8888/applets/" href="testehellojws.jnlp">
    <information>
        <title>App Hello</title>
        <vendor>My App Jnlp.</vendor>
        <homepage href="http://127.0.0.1:8888/Home.html"/>
        <description>My App Jnlp</description>
        <description kind="short">Appr</description>
        <icon href="images/icone.jpg"/>
    </information>
    <resources>
        <j2se version="1.6+" href="http://java.sun.com/products/autodl/j2se"/>
        <jar href="hello.jar" main="true"/>
    </resources>
    <application-desc main-class="br.com.app.server.HelloJWS"></application-desc>
</jnlp>

Please edit your question and just let me know it is edited.

OK

Did you miss the part about the documentBase?

I didn't.

I would recommend removing the space in the applet name attribute.

Done

Can you run any other JNLP embedded applets? E.G. the small (sand-boxed) GIFanim applet at my site?

Yes

What info. do you get reported from here?

java.vendor: Sun Microsystems Inc.
java.version: 1.6.0_26
os.name: Windows 7
os.version: 6.1

Answer 1

<application-desc main-class="br.com.app.server.HelloJWS"></application-desc>

That is the descriptor for a Java application (as opposed to an applet). For an applet, use something more like..

<applet-desc main-class="br.com.app.server.HelloJWS"></applet-desc>

Note:

1. Even that is not a correct descriptor for an applet, which must explicitly state a documentBase, name, width & height. See the applet-desc section of the JNLP File Syntax for more details.
2. It must (of course) be an applet. It is not possible to 'embed' an application into a web page using this technique.
3. JNLP and the Java Plug-In (required for both applets and web start) was deprecated and removed from the API in Java 9.
