JNLP as a Applet in HTML page

问题

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

回答1:

Your jnlp_ref should probably be an absolute URI, e.g. http://127.0.0.1:8888/applets/testehellojws.jnlp

Also there is a stray space at the start of your code value (though this is probably not the cause of your problem.)

回答2:

<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.

Checking on a related post, I decided to test the tag

<OBJECT>

. I thought that this would not work with JNLP, so we had tested before. After changing

<APPLET> 

to

<OBJECT> 

and referencing my jnlp file as a parameter, it worked! The browser ignores the code and archive parameters and run my JNLP.

thanks.

Try to remove [archive="CompatibilityApplet.jar"]
