[Savannah-users] Unable to run GUI application using cross-compiled jamv

Subject: [Savannah-users] Unable to run GUI application using cross-compiled jamvm for arm

Hello everyone, 

First of all I apologize for this direct message. I went through the website and only found this address where I can post my query. I am sorru if I posted at the wrong place. Below is the description of the problem we are facing.

We have cross-compiled the gnu classpath 0.98 and jamvm 1.5_4 for our arm xscale device. When we run helloworld program, it works perfectly fine. But when we run gui applications, there is no response. Below are our commands which we gave for cross-compiling: 

./configure --host=arm-xscale-linux-gnueabi  --prefix=/usr/local --disable-examples --with-x --disable-qt-peer --disable-gtk-peer --disable-gconf-peer --disable-plugin --enable-alsa --disable-dssi --with-escher=/home/warrior/java-project/escher-0.3/src   --enable-local-sockets --enable-collections --enable-xmlj --disable-Werror  --enable-tools 


make install 


./configure --host arm-xscale-linux-gnueabi --prefix=/usr/local --with-classpath-install-dir=/usr/local –enable-ffi 


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 java.awt.Font.getPeerFromToolkit( 
Caused by: java.lang.NullPointerException 
   at java.util.Properties.load( 

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.
