issue using jfree chart with gnu classpath 0.98

[Dhaval Yoganandi]

Hi GNU classpath team,

I'm facing some problem using jfree chart with GNU classpath 0.98 and
JamVM. I'm using a redhat based linux which is only console based linux
and doesn't support desktop and graphics. while running following demo
in my machine with JamVM I get NullPointerException but it is working
fine with JDK 1.5 with update 14. While generating chart with jfree
chart it is also giving the same error.

import java.awt.Font;
public class FontDemo{
       public static void main(String args[]){
               Font f = new Font("SansSerif", Font.BOLD, 18);
               System.out.println(f.getName());
       }
}

OUTPUT:
/bin/jamvm/bin/jamvm -cp . FontDemo      Exception in thread "main"
java.lang.NullPointerException
  at java.awt.Font.getName(Font.java:427)
  at FontDemo.main(FontDemo.java:5)

can you shed some more light on this issue ?

Hi,

I'm not part of the GNU Classpath team, but I'm using it and well, I have to

say that I love it! At least for embedded systems it's great...

But to answer your question, the method font.getName() isn't implemented
(yet) in GNU Classpath 0.98. You can check the coverage for GNU Classpath
against Java 1.5 on this site: http://www.kaffe.org/~stuart/japi/htmlout/h-
jdk15-classpath.html

There you can find: 'method java.awt.Font.getName(): missing in classpath'.
What is a nice answer I guess... It don't means that you can't use the
java.awt.Font, but the method .getName isn't implemented yet.

I hope this is a good answer for you question...

Good luck,
Jan Pannecoeck

Jan,

Thanks for the positive comments.  However, the link you refer to is
very outdated (2007).  If you check:

http://builder.classpath.org/japi/jdk15-classpath.html

you will find results against the current version of GNU Classpath,
rebuilt several times daily.
Links to this are available on the GNU Classpath homepage:
http://www.gnu.org/software/classpath

getName() is implemented, that's why it throws a NullPointerException
rather than not compiling.  Dhaval, please file this as a bug at
http://gcc.gnu.org/bugzilla

Andrew,

Thanks for the remark, I didn't know I was checking against an old
implementation of GNU Classpath! Thanks for the link to the new site!!

Dhaval, sorry that I gave you the wrong answer!! I hope your problem can
be fixed soon!

Good luck,
