JNLP as a Applet in HTML page

StackOverflow https://stackoverflow.com/questions/7313317

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

Was it helpful?

Solution 3

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.

OTHER TIPS

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.)

<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.

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