Subject: Re: Running applet. Another question.
Well, it's amazing, but this worked. I swear i would have never resoved
this problem if you didn't help me. And as far as i remeber it was
mentioned in neither of numerious FAQs i read in vain attempts to find
the answer to the question. But another problem arised. Now i got the
following error:
---------------------------
Error: in loading image
java.lang.NullPointerException
at
com.sun.j3d.utils.image.TextureLoader.getTexture(TextureLoader.java:342)
at ColumnScene.<init>(ColumnScene.java:70)
at ExClip.buildScene(ExClip.java:98)
.........
---------------------------
Looks to me like you passed a null Image object into TextureLoader
constructor, so that the subsequent call to getTexture() got a
NullPointerException when attempting to access the Image's methods. This is
likely the result of not finding your texture file.
Remember, the applet i'm trying to run DID work as an application. All i
did was putting appropriate html into the directory with already
compiled classes. I ran applet in NS4.61 and tried to use ".", "./" as a
codebase or don't use codebase at all. I tried to put codebase in front
of and behind of code parameter. But nothing helped. Possilby that's
because an external file is being read and some kind of security
violation happens again.
This is not on the surface a security issue. I believe that it's just a
matter of installing your textures in the proper place on the web server host
machine and you probably need to specifiy the texture files as URLs, not simple
path names since they are now being found by the web server using http
protocol. Codebase needs to be a URL. For instance if your web server is
foo.bar.net and your classes are installed under /usr/local/http/htdocs/classes
and htdocs is where all your HTML files go, then your codebase would be
http://foo.bar.net/classes.
HTH,
