Hi!
Our application needs to run under JDK 1.2/1.3 and JDK1.1 + Swing1.1.1. 
(customer requirement)
We can not find a way to develop swing applications with GridBagLayout 
using the designer of  JBuilder 4.

The problem is that the designer generates code using 
java.awt.GridBagConstraints with
a constructor only available since JDK1.2:
JDK1.3 (Designer of JBuilder 4.0):
this.add(pnlPrimary, new GridBagConstraints(0, 0, 2, 1, 1.0, 0.0 
,GridBagConstraints.CENTER, GridBagConstraints.HORIZONTAL, new 
Insets(10, 10, 10, 10), 0, 0));

This Code can not be run under JDK1.1 +Swing!!!

When changing the JDK to 1.1 and adding the external swing packages to 
the project the designer, we still
can develop with the Designer but the generated code is not complete:

JDK 1.1.8:
this.add(jButton1);

The GridBagConstraints settings are simple omitted, so the GUI looks 
strange :-(
(In addition there are some NullPointerExceptions in the message tab)

I think GridBagLayout is one of the most widely used layouts, so this is 
a serious problem.
Does anybody have a solution for this problem ?

Thanks in advance

Stefan
