Message:

Why java.lang.NullPointerException?

Posted by Blanca on November 29, 2000 at 5:04 AM

Hi everybody,

Please I need help, I don't understand this java error and I don't know what else to do.

I have to packages A and B

When I run package B alone, it works perfect, but when I call package B from package A, then I get the following error:

java.lang.ExceptionInInitializerError: java.lang.NullPointerException
at javax.swing.ImageIcon.
at com.borland.dbswing.DBTextDataBinder$UndoAction.
at com.borland.dbswing.DBTextDataBinder.
at com.borland.dbswing.JdbTextField.commonInit
at com.borland.dbswing.JdbTextField.
at com.borland.dbswing.JdbTextField.
at guiapp.UmlAppFrame.jbInit
at guiapp.UmlAppFrame.
at umlcfg.UmlCFGFrame.applicationButton_actionPerformed
...
...
...

guiapp is package B
umlcfg is package A

I get the error in a line that has the following code:

rValue = new JdbTextField();

Thanks for any suggestions or help,
Blanca
