Hi !
When i try this i have this error:
NameError: global name 'WebwareError' is not defined
Another question...
How to call Webware Servlets methods from PSP ?
In the PSP page they say that PSP's have full access to the WebKit Servlet
API.
But... How to do this ?
Another thing... How to use the htmlinfo() method from req (HTTPRequest) ?
See ya !
