Portlet + Applet WorldWind Java + BasicDemo = works ;)

[pred]

Hi !
With the help of Vash my coworker I have deployed on Liferay Open Source Portal 4.2.2 the WorldWind Applet.

Some steps :
1 - Refactor a bit BasicDemo.java in the SDK (application -> applet)
( use JApplet instead of Applet )
2 - Build the jar and...
3 - .. DON'T Forget to SIGN IT !!!! ( multiple local access )
use keytool and jarsigner from your jdk

4 - copy BasicDemo.jar and worldwind.jar on your applet directory with full jogl and gluegen lib ( use the pack from their website )
5 - here some sample code for your jsp page ( we use JOGLAppletLauncher )

            <applet code="com.sun.opengl.util.JOGLAppletLauncher"
                    width=600
                    height=400
                    codebase='<%=response.encodeURL(request.getContextPath() + "/applet")%>'
                    archive="jogl.jar,gluegen-rt.jar,worldwind.jar,BasicDemo.jar">
                <param name="subapplet.classname" VALUE="worldwinddemo.BasicDemo">
                <param name="subapplet.displayname" VALUE="WorldWind">
                <param name="progressbar" value="true">
                <param name="cache_archive" VALUE="jogl.jar,gluegen-rt.jar,worldwind.jar,BasicDemo.jar">
                <param name="cache_archive_ex" VALUE="jogl.jar;preload,gluegen-rt.jar;preload,worldwind.jar;preload,BasicDemo.jar;preload">
            </applet>

6 - Enjoy, your 'google Earth' thing on your web page in full 3D ( auto load of native library)

Any link to try it out ?

[pred]

Yes I will upload on my personnal Host the applet thing ( without portlet, there isn't any J2EE server ).

Today I will try to refactor again the main applet class, I don't like all these 'private static' things ^^.

I have to work on Rss layer too, my applet have to communicate with the portlet to edit geoRSS flows : A Double Click on the 3D World add coordinates to an HTML input outside the applet with the help of JSObject. This is to generate geoRSS information ( a servlet translate informations on DabaBase or write them in a xml temp file readed by the applet ).

I don't know if I'm truly understandable, my English is bad ( 'Oh Toulouse !' ), and this is a bit new for me ^^

Any new status on this?

Hi all,

I did the applet starting from the World Wind BasicDemo code, built a JAR, signed it with jarsigner and a key I created using keytool. I created the HTML file as suggested by pred, just changing the path.

When I open the HTML file, I receive the message
Error : Start failed : class not found : worldwinddemo.BasicDemo

I checked again the JAR file, which is correct since the signed file worldwinddemo/BasicDemo.class is there.

The applet tag part in the HTML is the following (the applet and all the libs and native libraries are in the same directory called "GeoSel"):

        <applet code="com.sun.opengl.util.JOGLAppletLauncher"
                width=600
                height=400
                codebase="file:///Users/frank/IdeaProjects/GeoSel/"
                archive="jogl.jar,gluegen-rt.jar,worldwind.jar,BasicDemo.jar">
            <param name="subapplet.classname" VALUE="worldwinddemo.BasicDemo">
            <param name="subapplet.displayname" VALUE="WorldWind">
            <param name="progressbar" value="true">
            <param name="cache_archive" VALUE="jogl.jar,gluegen-rt.jar,worldwind.jar,BasicDemo.jar">
            <param name="cache_archive_ex" VALUE="jogl.jar;preload,gluegen-rt.jar;preload,worldwind.jar;preload,BasicDemo.jar;preload">
        </applet>

I am using Mac OS X 10.4 and Java SDK 1.5.0_07.

The original BasicDemo application works perfectly. Does somebody have an idea why the applet doesn't?

Thanks!

Hi ciccio !
Please post your BasicDemo.java , I'm feeling troubles with it ^^

I put my applet version on a sample html page ( HERE).
I can't show Edit GeoRSS functionnality and Layer Manager because there are in my portlet application. I'm working with Liferay portal, jsr-168 JSF-MYFACES Portlets and DWR Ajax Proxy.

And yes, there is some PatMurris work on this !! ( I yell every days I LOVE YOU PAT from Toulouse in France ).
For fun try multiple shift and click on map ^^, this is part of edit GeoRSS functionnality.

Hi pred,

That's really great, WW in an applet. I'm quite new to java (as many people here...).
Could you explain more in details how to do it ? What do you change in BasicDemo to make it an applet ? My first experiments just gave me a blank panel...
Please please please !
Thanks

[ciccio]

Hi pred!

Thank you for your reply.

Below my BasicDemo code, I'm not sure whether I the applet has some problem, I didn't do a clean refactoring (I'm using JIdea and couldn't find).

However, I think the main problem is the OS. Your applet runs fine on Windows but on Mac OS X I get the same error message:

Error : Start failed : class not found : worldwinddemo.WorldWindIcare

So the problem is most probably the JOGL libraries on Mac and I have search in that direction.

Ok, thx for your reply too. It's quite strange applet doesn't work on Mac OS, BasicDemo contains some MacOS specific lines. I will search a work around later. :'(

Hi pred,

Unfortunately Java is not that plattform independent when it comes to more complex and interesting applications...

I will also try to find how to download and make those native libraries on the Mac work, independently of World Wind, since the problem must be with the Java's Open GL.

Regarding the Mac-specific lines, they seem to have no effect (except from the application name in the menu bar). Even after deleting them, the BasicDemo application works as with them.
