JApplet NoClassDefFoundError

Question

I\'m writing an Japplet on Eclipse, and from a moment to another, it stopped to work on the html page.

Here are the errors:

  Exception in thread \"threa         


        

Answer 1

1st thing you did not add gson library in your classpath and second your request(GET /static/java/com/google/gson/Gson.class HTTP/1.1) is wrong.

If you have gson jar under /static/java like MapGenerator.jar, you could make request for gson jar same as you did for MapGenerator.jar. But you can not make request to get class from that jar.

Answer 2

Apparently nobody told me that I cannot insert a Jar inside another Jar, and hope that all works well.

So I put my JAR libraries in the same folder of the applet, and I load the applet this way:

    <applet name="mapGenerator"
            id="mapGenerator"  
            code="main.MapGenerator.class"
            archive="{{STATIC_URL}}java/MapGenerator.jar, 
                            {{STATIC_URL}}java/gson-2.2.2.jar,
                            {{STATIC_URL}}java/plugin.jar"
                     >
                    <param name=id value="{{building.id}}">
                    <param name=piani value='{{floors}}'>  
            MAYSCRIPT
    </applet>
