Forms

2002-07-31 Thread Richard





Hi Guys,
 
Good Day!
 
On http://xml.apache.org/cocoon/tutorial/tutorial-develop-webapp.html
 
It is written that...
The website specification 
is missing the tags for form building, we will provide an example 
here: 
 
Where can I find the "tags for form building" syntax and description?
 
in the codes... 
 
    
  You can 
create a department by typing in 
the  name and pressing 
the "submit" button.    
    
  Name: 
    
        
  * These 
fields are required.    

 
How does the handler="create-dept.html"> attribute work?
 
The  element is not required by 
the FormValidatorAction right? 
This element were used only by the xsl 
transformation.
 
Thanks!

cocoon 2.0.3 on tomcat 3.2.4

2002-07-31 Thread Crispin Murphy

Hello there. I am trying to get cocoon up and running in tomcat 3.2.4.

I have done the following:

1. Installed tomcat.
2. Loaded the cocoon.war file into $tomcat_home/webapps.
3. Removed the jaxp.jar file from tomcat/lib. I would remove
parser.jar but parser.jar does not exist.
4. Installed xercesImpl-2.0.0.jar, xalan-2.3.1.jar, and xml-apis.jar
into tomcat/lib.
5. Installed the same 3 files into Java Home/jre/lib/endorsed/

Every time I try to access the cocoon page:

java.lang.NullPointerException
