seems your dependencies are not included into your jar. Open your .jar and see whether all the dependency classes (like com.mysql.cj.jdbc.Driver) are inside. If they are not please see, Including dependencies in a jar with Maven.

[ERROR] Line 16: Unexpected exception while processing element 'inherits'

You have this line in your module .xml file:
<define-property name="gwt.logging.popupHandler" values="ENABLED, DISABLED"/>
You also have the same line in one of the inherited modules. This leads to this error. Make sure you only have it in one place.

Java Failed To Validate Certificate Java 8 Update 25

I am trying to access different sites that use Java and every time I get the failed to validate certificate error. I have looked at the security setting for this version and there are only 2 options, high and very high. How do I get around this error? I shouldn't have to add every site I want to use to the exception list. Here is the error

Where is an applet trying to load a class from?

I'm trying to debug an applet that occasionally fails with the stack trace below (on the Java Console).
It looks like it's trying to load binaries and it's getting an HTTP REDIRECT which isn't legal (perhaps because of the applet sandbox?).
Is there any way to turn on verbose class loading output (or other debugging that might be useful) on the Java Console? If this were a standard Java application (as opposed to an applet), I would put "-verbose:class" on the command line and see what I get - but I don't know how to do that with an applet.
I don't have access to the source for the applet - so I can't add any kind of instrumentation to the code itself.

You can add the -verbose:class to the command line of java by going to Control Panel, Java, Java, View, then editing the 'runtime parameters'.

To make your applet get sources NOT FROM its native host you have to sign it;
Here are some helpful tutorials

You need to sign the applet with a certificate.
see the sun Java site on signed applets for a description of how and why you need to do this.
