I read a lot, I tried everything.. but I still not able to:
launch a transformation from browser
I found the documentation very poor about this.. I mean for a basic user like me..
Environment: Windows
PDI 4.4 stable -> directory: C:\Documents and Settings\Administrator\Desktop\data-integration
Java jre7 -> Environment variable: JAVA_HOME = C:\Programmi\Java\jre7
I try to explain what I did from the start. I think well..
I launched spoon.bat
created a new repository:
1.jpg
created a transformation that generate a random number and save it in a file txt on the desktop
Launching the transformation locally (Transformation2.ktr) , all it's ok..
After this I launch Carte from cmd
Carte.bat 127.0.0.1 8081
the URL http://localhost:8081/kettle/status/
give me the correct initial page

Now the problems.. how to launch Transformation2.ktr?
I read that the previous kettle status page just show something previous launched.. How I can launch it?
I tried this:
http://localhost:8081/kettle/execute...ormazione2.ktr
or with a user and password that I don't have..
http://localhost:8081/kettle/execute...ormazione2.ktr
but I always get an error:
This is my C:\Documents and Settings\Administrator\.kettle\repositories.xml file
I tried to put .kettle folder on C:\Documents and Settings\Administrator\Desktop\data-integration
and setting an environment variable
KETTLE_HOME = C:\Documents and Settings\Administrator\Desktop\data-integration\.kettle
but I get always the same result
I also tried to change transformation passing output to servlet (I don't know what this means)

Finally I also tried to create a server slave (I don't know what this means)

Final objective is to call the transformation from another pc on the net.. I imagine that I have to trouble with that because I tried to call status page and there are differences if I start Carte with 127.0.0.1 or with 192.168.0.2...
