Message:

Why JVM report tableScrollPane1.getViewport().add(jdbTable1, null); NullPointerException errors?

Posted by Xieyun on November 26, 2001 at 1:45 AM

I found put these words in the codes that report error:
tableScrollPane1.getViewport().add(jdbTable1, null);
but use jar these codes have not problem.
Error is so:
java.lang.ExceptionInInitializerError: java.lang.NullPointerException
