Re: GraphStream java applet - corrupted graphstream.jar ? the org/miv/graphstream/ui/graphicGraph/rgb.properties file is not found

Jerry,

Then may be a generic java 1.7 problem, for Windows platforms: http://stackoverflow.com/questions/17572293/java-applet-cant-find-resources-in-jar-if-run-locally

Do you really need graphstream to run as an applet ?

Kind regards,
Ovidiu

Ovidiu,

Yes, the rgb.properties is certainly in the .jar file:

remmeh-mba:260 project remmeh$ jar tf suffixtree.jar | grep rgb

org/graphstream/ui/graphicGraph/stylesheet/rgb.properties

I should note that I am using the Eclipse IDE and my applet runs just fine when launched from within the IDE. I only get this issue when running from the .jar file generated by Eclipse. This seems to be a problem that others have encountered (not specific to GraphStream) but everything looks to be in order 

Any other ideas?

Thanks,

Jerry

Hi,

This is a quick debug hint: can you check is rgb.properties is in the jar file as well ?

If it is, the issue might be with the build process ...

Kind regards,
Ovidiu

hello,

I am using GraphStream for a university project and I am having some trouble
getting a GraphStream applet to work well embedded in html.

Upon loading my applet, the Java console prints the following:

        ... 21 more

It appears that in org.graphstream.ui.graphicGraph.stylesheet.StyleConstants
the exception is thrown here:

                URL url = "StyleConstants.class.getResource("rgb.properties");
                if (url == null)
                        throw new RuntimeException(
                                        "corrupted graphstream.jar ? the
org/miv/graphstream/ui/graphicGraph/rgb.properties file is not found");

However, rgb.properties definitely exists in the same context as
StyleConstants, both are in org/graphstream/ui/graphicGraph/stylesheet/.

Any idea as to why this might be happening? I am using gs-core-1.2.

Thank you!
