JAMVM:
./configure --host arm-xscale-linux-gnueabi --prefix=/usr/local --with-classpath-install-dir=/usr/local --enable-ffi
make
make install
We then transfer the required files to our device.
we run our programs as
jamvm helloworld
jamvm -verbose Button
helloworld runs perfectly fine and gives the desired output in proper time. But when we run any gui sample we receive following error:
Exception in thread "main" java.lang.ExceptionInInitializerError
at gnu.java.awt.peer.x.XToolkit.getClasspathFontPeer(XToolkit.java:208)
at java.awt.Font.getPeerFromToolkit(Font.java:329)
...
Caused by: java.lang.NullPointerException

at gnu.java.awt.peer.x.XToolkit.getClasspathFontPeer(XToolkit.java:208)
Can someone please guide us on this. This is becoming very critical.
Earlier we thought this to be jamvm issue, but on jamvm forums , it can out that we are missing something while cross-compiling gnu classpath.
It will be a great help if someone can direct us towards fixing this to see what we are missing to get the gui applications running with jamvm. We have made a small sample using java swing which creates a frame and 2 buttons over it.
Thanks in advance.
