Re: Jexl in embedded Pipeline

Hello Greg,

I got  what I was looking for by using a programmed Pipeline.
Starting with Velocity to fill up an xmlstring with Hibernate bean data.
The only problem is that sometimes when I call Hibernate I get an error 
because there is no Hibernate session.
Maybe the reason is how I placed the lazy loading filte in the web.xm.

When I have time I investgate several other opportunities.

JAXBGenerator here I am missing some fields. I still don't know what is 
the reason. Maybe because I mix up different annotations.(Hibernate,  JAXB)

What is also working is simple calling the cocoon pipline snippets by 
localhost:8888

I am also trying to get the result of the URLResponse in the 
application. But till now I was not successful.

I also succeeded to replace Velocity by using the StringGenerator.

The last aspect I am investigating is using more cloud technology by 
sending only links.
But here I have to think about that the Information should not publicly 
accessible.

Greetings
Heiner
