hello,
I am trying to run swing examples with kaffe+nanox but it is giving
error as:
java.lang.NoSuchMethodError: java/awt/Toolkit.addAWTEventListener(Ljava/awt/event/AWTEventListener;J)V
at javax.swing.JPanel.<init> (JPanel.java:109)
at javax.swing.JPanel.<init> (JPanel.java:85)
at javax.swing.JRootPane.createGlassPane (JRootPane.java:567)
at javax.swing.JRootPane.getGlassPane (JRootPane.java:474)
at javax.swing.JRootPane.<init> (JRootPane.java:526)
at javax.swing.JFrame.createRootPane (JFrame.java:221)
at javax.swing.JFrame.getRootPane (JFrame.java:205)
at javax.swing.JFrame.frameInit (JFrame.java:152)
at javax.swing.JFrame.<init> (JFrame.java:114)
at test2.main (test2.java:8)
so during its analysis i found that the program crash when it internally try
to call any UImamager.java function. I also found inside UIManager.java it
stuct inside static{} block when a call to functoin setLookAndFeel(LookAndFeel newLookAndFeel)
is made. Inside setLookAndFeel stuck at:
newLookAndFeel.initialize();
I found this function is defined in BasicLookAndFeel.java file. Inside
this intialize() function it stuck at:
toolkit.addAWTEventListener(popupHelper, AWTEvent.MOUSE_EVENT_MASK);
Here i found there are two Toolkit.java file:
1)/software/kaffe-1.1.7/libraries/javalib/awt-implementations/kaffe/java/awt/Toolkit.java
2)/software/kaffe-1.1.7/libraries/javalib/external/classpath/java/awt/Toolkit.java
I found that this function defined in (2)Toolkit.java but it try to include
(1)Toolkit.java and hence not able to find the function addAWTEventListener(popupHelper, AWTEvent.MOUSE_EVENT_MASK)
SUGGEST some methods or clue so that i can get out of this problem.
Thanks
Praveen Kumar
