Follow-Up: Unsigned jar runs, signed doesn't!
Diego Pietralunga
the following.Former code crashed either.
There is an uncaught ERROR while loading the image.
This debug output shows where code gets, actually there is a
ClassCastException in 1.3.At the end of the post, I'm putting the error
from 1.4 (which is a SecurityException causing an
ExceptionInInitializerError while talking about CA certificates)
ClassLoader cl = ImgResourceAnchor.class.getClassLoader();
URL u =
cl.getResource("com/mycompany/myApp/res/img/main_background_2-460-300.jpg");
//
if (u != null)
{
Message.debugMsg("BackgroundJPanel: init(): " + u.toString());
this.theImgURL = u;
}else
{
Message.debugMsg("BackgroundJPanel: init(): img url is null!");
}
if (image==null)
{
Message.debugMsg("BackgroundJPanel: init(): creating image icon");
try{
/****** GETS STUCK HERE *******/
this.theImageIcon =
new ImageIcon(this.theImgURL);
}
catch(Exception ex)
{
Message.debugMsg( ex.getMessage());
}
catch(Throwable t)
{
Message.debugMsg( t.getMessage());
}
/***** NON EXCEPTION CAUGHT ************/
Message.debugMsg("BackgroundJPanel: init(): getting image");
image = this.theImageIcon.getImage();
Message.debugMsg("BackgroundJPanel: init(): got image");
ww = image.getWidth(this);
hh = image.getHeight(this);
