[Bug cp-tools/28012] New: Strange error message from appletviewer

[hendrich at informatik dot uni-hamburg dot de]

I just tried the classpath appletviewer (from cvs 2006.06.13 with jamvm on x86)
for the first time. Several of my applets work fine:

http://tams-www.informatik.uni-hamburg.de/applets/cmos/index.html
http://tams-www.informatik.uni-hamburg.de/applets/sram/index.html

but this one dies with an obscure error message:

http://tams-www.informatik.uni-hamburg.de/applets/jfig/applet.html


appletviewer http://tams-www.informatik.uni-hamburg.de/applets/jfig/applet.html

   at gnu.classpath.tools.appletviewer.Main.main(Main.java:272)

My source code says the following:

  public void init() {
      viewer = new JFigViewerBean();
      this.getContentPane().add( "Center", viewer );

      try {
        urlname = getParameter( "URL" );
        viewer.setURL( new URL( urlname ));      <-- line 31
      }
      catch( Exception e ) {
        System.out.println( "-E- " + e );
        e.printStackTrace();
      }

  ...

and the following html is used in the applet page:

<applet
  code=jfig.gui.JFigViewerApplet
  codebase=archive
  archive=jfig-bean.jar
  width=600
  height=500
>
<param name="URL"
value="http://tams-www.informatik.uni-hamburg.de/applets/jfig/
gallery/jfig-class-diagram.fig">
</applet>

So, the parameter value is a fully quoted absolute URL, located on the same
server as the applet itself. This should work.


Also, jamvm is completely dead after the above error and doesn't react to
cntl-c anymore. I don't like programs to intercept cntl-c...
