Geogebra 3.0

Greetings,

Has anyone tried to embed geogebra applets in the new version (3.0) using the Geogebra Filter. I can't get it to work properly. An error box appears saying i must update Geogebra because the version is different.
The problem must be in the filter because it works when exported by the application. Can anyone help me?

Thanks

Daniel

hi again,

I guess i found the solution afterall smile I replaced the .jar files in the filter/geogebra folder with the newest ones. Be sure to delete files from the JVM cache.

Hi Daniel

I jump to your own discussion wink and have one question. You replace the .jar file or files from the latest filter package? Last files from january 2007, is this correct?

Hi andy,

You must get the .jar files from the new geogebra release (available at geogebra.org) and then put them in the geogebra filter folder on moodle.

Best Regards

Daniel

I tried that, but noticed that there are some .jar files in the filter module but not in the standard distribution (I think it was geogebra_properties.jar?) Which of the libraries do I need to copy over?

When I upload my project, I get a "class geogebra.Geobra applet" error.

Thanks for the help! smile Derry

Hi, Daniel. I moved the following jar files from Geogebra folder to Geogebra filter:

geogebra.jar
geogebra_export.jar
geogebra_gui.jar
geogebra_cas.jar
geogegra_properties.jar

But, geogebra filter sends the same window: Any idea? TIA.

I mean there comes only three file inside:
- geogebra.jar
- geogebra_properties.jar
- geogebra_jscl.jar

but i have the same problem as you Monico, this was the reason i jump to this thread. I did not find the time to check this again, one thing Monico, did you clear the cache of your browser and java!?

Hello Everyone,

In fact, geogebra_properties.jar is not a part of the distribution. I kept the filter version and added/replaced the jar's from the distribution. So the filter folder has the following jar files:

geogebra.jar
geogebra_cas.jar
geogebra_export.jar
geogebra_gui.jar
geogebra_jscl.jar
geogebra_properties.jar

These are the files geogebra generate when you export your application to a applet.

ATTENTION: You must clear your browse's cache, JVM cache and temporary files like Andy suggested. Normaly there's a Java Control Panel where you can do that. In windows pltaforms it usually stands on you task bar.

Hope it helps...

Daniel

Hi, Andy. I cleared the browser cache and it works without problem.

Thank you

*.ggb file doesn’t start an applet.

In the past it works fine. Now we are using: Moodle 1.8.2+ (08302007)
Maybe I have changed something but what??

The javaconsole gives me the next information:

java.lang.NoClassDefFoundError: geogebra/gui/menubar/D

at geogebra.GeoGebraApplet.init(Unknown Source)

at sun.applet.AppletPanel.run(Unknown Source)

at java.lang.Thread.run(Unknown Source)

Hi Guido,

How did you udpated moodle? Maybe the geogebra filter folder had been replaced and the jar files are now outdated. Try updating the jar files by copying to filters/geogebra the newst jar files available with the new distribuition of Geogebra.

And remember...you must clear JVM and browser's cache after udpating the jar files.

Hope its helpful!

I always thought that geogebra works fine. But now I am not so sure. I haven't noticed it, because the geogebra software is always on my local computer. So Please can someone delete the geogebra software on the local computer and than try a geogebra-file in moodle.

This problem could have been avoided if the GeoGebra download that you get from the Modules and Plugins database contained only the filter code and not the applet. The README would explain that you must install two things: the filter (in this zip file), and the latest version of the applet, which you can get from sourceforge.

If done this way, the maintainer of the GeoGebra filter will not have to create a new download whenever the version of GeoGebra changes. Responsibility for version maintenance shifts to the admins who install the filter.

Sorry to resurect an old thread but the simplest solution to this is to use the webarchive so that it automatically updates to the lates version, that way no-one ever need to update it...

Attached it the filter with the archive changed to the web-archive.  If you replace the filter.php file that is in the original plugin with this you can then delete all the jar files...

Hope someone find this useful...
