Subject XMLFORM WizardAction compilation problem
Date Tue, 30 Jul 2002 02:09:21 GMT
Hello,

I am new to XMLFORM. I followed the howto
instructions. I use Jbuilder tool. I beleive, the
userbean and WizardAction has to compiled. While
compiling I get tht following error:

************************************
"WizardAction.java": Error #: 300 : class UserBean1
not found in class rertn_frontapp.WizardAction at line
172, column 5


"WizardAction.java": Error #: 300 : class UserBean1
not found in class rertn_frontapp.WizardAction at line
172, column 25

************************************


The WizardAction is not able to access the userbean.
and the compilation fails. Is there something I am
missing? Please excuse my naievty to XMLFORM.

The code is below , basicaly i modified and remarked
the cocoon's sample code:
