Hi all

I've created an applet with a main that can 'stand alone' via execution as

        java MyThing 

and all works well. Note that this applet/application does not fetch images.
Next I try to create an applet that should, if needed, be able to stand
alone in the same manner. However, it crashes as follows:

Exception in thread "main" java.lang.NullPointerException
        at java.applet.Applet.getAppletContext(Applet.java:83)
        at java.applet.Applet.getImage(Applet.java:110)
        at java.applet.Applet.getImage(Applet.java:122)
        at Gazette.getImage(Gazette.java:189)
        at Gazette.addFutureTense(Gazette.java:331)
        at Gazette.addSectionContent(Gazette.java:435)
        at Gazette.addContent(Gazette.java:467)
        at Gazette.makePublication(Gazette.java:230)
        at Gazette.init(Gazette.java:172)
        at Gazette.main(Gazette.java:535)

The trace indicates that there is no applet stub. Looks like I need one to
deal with images outside the appletviewer? I don't recall seeing that in the
documentation, but more importantly...what steps do I need to take to be
able to have a standalone application read in an image? 

Thanks

julie
